[Q] ICS Wimax Slower Speeds, Persistant IP Related?? - Samsung Epic 4G Touch

Ok I can't ask in developers pages, but I have an observation from my attempting to get better 4g (wimax speeds) in ICS.
I have come up with a conspiracy theory, that's may not be true, but conspiracies are fun.
Ok so I decided to try out the Blue Kuban ICS rom, its got a lot of nice features BTW!!! Using the AGAT kernel v.0.6.7. with the 0.2.2 repack.
I have tried a myriad of different modems, such as EL29, FI127, and FF18 the one thing I noticed is some of the modems have better signal strength and signal quality (raises a question whats the best signal strength, and quality figures one can get? I've seen -69, and 24).
It has really been driving me insane that, I can't change my 4G(Wimax) IP in ICS, all it took in GB was a simple toggle on and off of my wifi.
I was going through my speed test results and among my first speed tests using Blue Kuban, and the FI127 Modem, I got over 8Mbits down, was happy and went to sleep played with a few other things on the phone.
Next day, never got above 3Mbits... Even at 3AM tried different servers, of course I know speed test isn't the end all be all test, but even a broken clock is right twice a day.
Started looking at phone information, and I noticed that the higher speed was connected to a different IP as well as had a different visible IP. This begs the question, why can't we manually try and change the IP, I've been trying to find something that alludes to this in the "WimaxHiddenMenu"

So far I haven't figured out if there is any way to change the Wimax DHCP lease, or get it to acquire a new IP.
So my conspiracy theory, has Google, colluded with companies like sprint to prevent people from taking advantage of their Data Rates, by assigning us throttled gateways? Is this really a Kernel bug, or is it a deliberate thing, why wouldn't they be able to make the Wimax work just as good, as in Gingerbread?? Is the source code that incompatible?
Here are some nice screen shots of my fail, and AIDs...

Of course now I'm just talking to myself, but I also read that there is a way to change, the 4G(wimax) modem MAC address, in ICS I suppose that would be a way of tricking the towers into thinking your using a different device, but I always thought MAC addresses were unique to the device, also I'm not sure how to construct a valid MAC address.
Is there more information on this, topic??
Has anyone figure out how to get the E4GT running ICS, to drop its DHCP lease, and acquire a new IP.
I was clued in to that what I seek is probably somewhere in /system/data or some similar directory.
But haven't found anything that I can read in plain english that may be wimax ip related.

Ok so I think I conclusively proved to my self that it isn't the persistent 4G IP address in ICS, that was causing my speed problems.
I used this Kernel repack
http://forum.xda-developers.com/showthread.php?t=1942823
The first Kernel repack (AGAT_FI27_repack.zip) gives me much better 4G speeds, on top of the blue kuban kernel.
The second repack (AGAT_FI27_repack_2.zip) you can download screws up the 4G speeds, with the blue kuban kernel.
I was getting in excess of 6-7Mbit down, with The first repack.
Out of Curiosity, I downloaded the latest AGAT Kernel, from The Kuban Updater, and installed it.
The speeds went back to mediocre, so I installed the AGAT_FI27_repack.zip over the latest AGAT_v0.6.8 Kernel.
Now I'm getting between 10-11Mbits consistantly!!!
Also I am using the FI27 Modem
So this is great News for People who have reverted back to Gingerbread roms.
So probably no speed throttling conspiracy regarding the persistent 4G IP, but perhaps and attempt at preventing IP Ban evasions.
Regardless, of the reason, I still like being able to reset, my IP. I found a buggy unstable IP changer, that works for changing the 3G IP, but just seems to hang with 4G for displaying any data, and the reset seems to restart the 4G but just hangs in the "getting new IP mode"
The app is called "IP Changer for Mobile Network" by Yu, buggy but sort of works...
Ok I think I'll get off my rant box now, and try and get past 10 posts, so I can link images and such :|

Hey OP... I enjoyed reading you talking to yourself and thank you for testing kernels for speeds for 4g on BluKuban... I have had similar frustrations but only have 4g at work not at home so have not had time to do the testing...
anyway... thanks and thanks for the jovial musings

[Q] Radio + Data Speed Question

With all the excitement going on with the Wimax being alpha tested in the CM ROM it got me testing my data speeds the last few weeks.
From my understanding 3G speeds should be decent and range between 1 - 3 mbps down, and using Sprints 3G network I am not coming close to that.
I am using the SpeedTest.net app for my results, and I have read from some posts that the app might not be that accurate.
Here are the results that I have been seeing (displayed as Mbps) using the closest server to me (Random Lake, WI - even though other servers are giving me the same low scores):
1/6/11 - .18 down and .37 up
1/6/11 - .16 down and .30 up
1/2/11 - .30 down and .77 up
12/27/10 - .45 down and .27 up
12/27/10 - .34 down and .27 up
12/27/10 - .12 down and .20 up
12/24/10 - .45 down and .70 up
12/24/10 - .15 down and .62 up
As you can see, not close to the 1 - 3 range that I would expect. I am checking that the icon is showing 3G and 1X when doing the test as well. Here is some information to help deduct and (hopefully) solve my issue.
My EVO is from release day, not the 004 hardware
I'm running CM 6.1.1
CM stock kernal that comes with it - 2.6.35.9 [email protected] #1
Theme is Project_Bliss HD (modded by me to include some different emoticons and Batman themed notification shade)
I have flashed all of the latest
*Radio - 2.15.00.11.19
*Wimax - 27167_R01 (even though where I live has no 4G)
*PRI - 1.90_003
*NV - 1.90_003
I have flash a Sense ROM and update Profile and PRL
I live in Appleton, WI area if that matters at all.
So am I just looking at my results wrong? If I'm not, what are some solutions that I can look at to improve my 3G data speed? Any other test I should run or try?

Thanks for letting Cyanogen know that. So it sounds like I'm not alone in this?
Are you having any issues?
Sent from my EVO (CM6.1.1) using XDA App
A lot of those results look like they could be from when you were connected at 1x speeds. Sometimes it seems like the status bar icon doesn't update quickly for the change in network type. Also, how strong of signal do you have. If you're at the edge of data coverage, the rate might be low because a lot of packets are getting lost in transmission. Have you seen what your speeds look like in other locations? In my home town I regularly get over 2mb, but when I was traveling a few weeks ago in some places I could barely pull 300k.
I have check all over town since my apartment is further away and gets lower strenght. Im getting the same results close or far away from a tower.
Sent from my EVO (CM6.1.1) using XDA App
i started noticing this with my evo aswell, actually about yesterday, my stats are about the same in the OP, i live less then a mile from the 4g tower, i've even been about 200 yards away and gotten crappy 4g signal, anywhere from only 3-4 dl, and barely 1 ul.
Hopefully this helps. I was also experiencing 1x speeds although the phone indicated 3G. I upgraded to an EVO after modding my Hero for the past year. Thus I was pretty comfortable with rooting, installing roms, etc. within 24 hours of getting my EVO I decided to root it and try out some of the roms available.
Almost immediately after rooting using unrEVOked I noticed signiffigantly slower data speeds. (I'm not pointing any fingers, only documenting what led up to this) I first tried out the latest CM6 rom. Upon booting it indicated 1x speeds though posts that I read stated that you are actually recieving data at 3G speeds. I think that CM6 may actually be reporting the data connection accurately while the sense rom is not. Using speedtest.net's app (I know it dosen't report speeds accurately) I was consistently recieving between 80-160 kbs download and 60-100 kbs upload. I then downloaded the same app to my wifes unrooted EVO and ran a side by side comparison. Using the same server and within seconds of testing each her EVO was downloading at 800-1600 kbs download and 600-1000 kbs upload while mine was still recieving at the afore mentioned speeds. I tried updating PRL, profile, running the stock rom to no avail. I then tried RUU and unrooting without any change.
I was convinced that either Sprint was throttling my connection or the transmitter in the phone was defective or damaged. I was ready to return the phone to Radio Shack where I purchased it last week but I decided to call Sprint and inquire about the throttling issue first. Sprint assured me I was not being throttled and they also thought I may have a defective phone but they asked if I would perform a ##DATA# before returning it. Amazingly enough this worked and my data speeds have returned to 3G speeds of around 1000-1400 kbs download.
I'll detail the procedure but I make no guarantees this will work for anyone else. Also you'll need your MSL, there are guides that detail how to obtain this or you can all Sprint and ask nicely. Also I did this while stock and unrooted and I haven't tried to reobtain root again yet so if this works for you while rooted let me know. Finally I believe you'll have to perform this using the stock dialer as I don't believe that the CM dialer will work for this.
Procedure is as follows:
Open dialer and type ##3282#. (##DATA#)
You should now be taken to the epst prompt. Choose "Edit Mode"
You will now be asked for your password. This is your MSL
Next you want to choose "Data Profile"
While in Data Profile hit the "Menu" button at the bottom of the phone.
Next choose "Restore" and allow the phone to reprovision.
Let me know if this works if you try it while rooted as I'd like to reroot again but I'm a little gun shy now that it's fixed again.
I'll give that I try and see what happens. I have to flash a stock ROM first and hope that any changes follow me along back to CM ROM. I am also going to try the Wimax kernal to see if that helps since that ks reporting to be a possibility.

this sorta helped me a bit, but i just also ended up flashing back to 1.77pri and nv, though i still have the latest wimax and radio and 60674prl on myn's rls5, however i'm still experiencing way below average data speeds as compared to what i used to, i have a release day evo with 0002 hardware, and .76 hboot, even my 4g's are slower then what they used to be.
FWIW, I experienced a drop in speed as well. I used to get 1-2 Mbps easy. Now all I get is around 500. Very strange.

i really hope your right, i mean the other day with cmWimax i nailed a 7.61, now i'm lucky if im even in the 3 range for moar gee's, lol, even with reg sense rom's i'm barely in 3 range as well, i have a tower that is only about 200 yards away that is 4g and it still suxor's.
I haven't had a chance to test the above, I'm about to start to do that.
I did try out Sprints Network Speed Test and got results from it above 1.0 finally. Then I tried using the speed test app and it was giving me location in Europo to test? This morning it is back to normal and both the speed test app and Sprints website both were giving the same results - around .80.
I'm going to flash the Wimax for CM and see if that helps out. If not, then I'm going to flash a Sense ROM and do the #DATA# trick listed above.
Here is the website for Sprints speed test website. You'll need the latest Flash installed from the market for it to work.

ok, so using the sprint site, i/m actually where i should be as before, back above 7 for 4g, not tested 3g yet, but working on it.
EDIT: wow, my 3g still blows, lol.

i have noticed though with this release of myn's that i do keep dropping 4g and reconnecting, something that i have never did before on other dev's rom's.
Well, both attempts to fix it didn't work. The new Wimax for CM didn't give me faster speed and the flashing to Sense ROM to do the ##DATA# didn't help either.
Anyone else have any ideas?

im clearly half retarded

so i thought i did the right thing...to start from the top...my old evo broke...got a new evo...didnt update the prl...rooted/flashed a new rom and boom...my internet blows...its stuck on 1x...so..i flashed a sense rom...updated the prl...now im missing something because when i go back to the roms i wanna use...its still stuck on 1x...what am i doing wrong?

You're most likely not doing anything wrong. I assume you're using an AOSP rom. Aosp roms show your true signal, if you're on 3g or 1x. Sense roms show 3g all the time, even if you're on 1x. Sense lies to you. Aosp shows the truth. Although there is now a mod that allows you to see true signal on Sense as well now.

A PRL is a "preferred roaming list" and has nothing to do with data speeds unless you're talking about data speeds when you're roaming. Do you mean that you are getting no 3G coverage at all?

Are you sure you are getting 3g at all? Sense doesnt tell you when you are on 1x unless you grab an app for that. Are the 1x culprits all aosp and you are just under the impression you are getting 3g on sense when in all reality you are not? Run a few speedtest.net tests and let us know what your speeds are on both on both. I doubt your speed changed.
hmmm...interesting....well im running MIUI...but its weird...because i used to get good signal...i wonder if maybe this is tying in too all the problems it seems a lot of people are having...im gonna run the speed test right now and see
signal and speed arent necessary related, though i believe aosp does calculate that into theirs. On sense it is (almost?) always separate. Anyhow I have only seen a few phones get "stuck" internally at 1x, no worries that would also be fixable.
You may just be having tower issues, thank sprint for that. Another good question is do you get 3g on a diff tower? drive out of the range of your current tower and see what ya get.
yea im gettin a steady 1x from home all the way to work which is about 15 miles away...
my first test:
Ping: 558ms Dl:125 Ul:148
second test:
ping: 807ms Dl: 126 Ul: 140
3rd:
ping: 786ms dl: 126 ul: 143
im not too knowledgable about this stuff....but i feel like the numbers are good right?
No, those are def 1x speeds. Sprint average is 540k. Being that you have used multiple towers i would assume its the phone. Grab easy settings from triforce, luke and see what the settings are. If you cant get back to 3g you may want to grab the 2g/3g toggle from triforce, luke for a buck and set it to hybrid or evdo only and see if that works. Its the only thing that helped me once.
I tried profile restores, other prls, everything. Have you tried any other prls? I wouldnt suggest a profile restore because you dont have 3g and it needs that to provision.
Have you gone into ##3282# (sense rom), and cleared your profile data (top item, then menu IIRC). This will cause the phone to reboot, and do an OTA activation on the subsequent boot.
Have you messed with your 3g settings - meaning, is the device being forced into cdma mode only??
Which rom did you specifically flash?
And I guess most importantly, before you did anything, did you ensure 3g/4g work with the phone in its stock state?

I had this same issues awhile back and the quoted text is what worked for me.
you can try a profile restore but it may not activate well without 3g. Sprint told me that themselves, so have others...though it did activate for me, i have seen people get stuck though for a bit...
well...from what i understand i guess i have no idea if 3g was working before...i know 4g did work fine...and it still works weather im using the wimax setting on a sense rom or even before i rooted it....so somebody give me a run down of what to try...i read a lot of those suggestions...and to be totally honest...i have no idea what too do...like i said im kinda new to this whole thing
nevermind...i found the thread with the whole step by step process...thanks for your help guys...i got it up and running

Seriously need Help. :/

I recently bought a used Epic 4gt, with a bad ESN, I have a GS1 and all i had to do was copy all my info to the new GS2. Im currently on boost my GS1 works fine so it was going to be pretty easy. I repaired the esn and flashed everything to GS2. Everything works except 3G. I tried everything I can think on from going to stock el26 to el29 to custom roms and back to stock. Tried using open DNS and changing APN to boost, with no luck. I have the 3g icon with up/down arrows and they flash. Under #data AAA-passes, it has an IP address, I get both 1x and 3G but when it comes to loading browser page or Google Play its no go. Tired different modems with no luck. I know my donor phone and GS1 are working just fine, with the same info applied as does the GS2. I dont know what else to try, I mean I get text and send text and make and receive calls, just no data coming in even with 3g icon present. If anyone can help me it would be great and will donate with paypal. GS2 currently sitting on EL13 modem with rogue 1.4.1 kernal and el29 TNZ blend 3.0 rom.
[email protected] in case i dont see the reply on the thread.
You've tried switching just the modems too right?
Sent from my SPH-D710 using XDA
Problem Solved wheww
Yes, did try just the modem from EG30 to EL29 EG31 FC07 and FC14. *note the best signal i got was from EL29 and EL13, but EL13 seemed to make my epic4gt act different but thats just me.
So heres what happened, since i live in a brick house i get really ****ty signal, for some reason but out side i get like 2 bars to 3. Anyways all was copied correctly but since the signal was weak the whole time i was trying to get it to work and didnt make any progress i ended up tweaking my settings in qpst. so that that broke my 3g and when i went back still no progress so i was stumped.
the next day started fresh and decided to call boost and have them refresh my account which ended getting a new msid and getting a sprint rep error 16. after that i had to reprogram my incognito and gs1 back to working condition. and also try to get my gs2 working but this time i had to go back and forth out side to get a signal and see if the error 67 stopped from coming up.
had to get flash prl 60681 to be able to update the prl and update the profile on my gs1, same thing with the gs2. after numerous attempt's i got it working finally took forever to lock a good 3g signal. still slow even in good area but i guess thats how gs2's are. this was suppose to be a smooth flash turned to nightmare but all in all good experience.
if anyone needs help let me know i think i can be of some help since this incident.
currently on Calkulin's_E4GT_ROM_v3.0 rogue 1.4.1 el29 all working now.
I personally love fd19 modem, it works by far the best for me. But every phone is different. Feel free to try later fed modems.
Another thought of mine was, of you go to your phone dialer, enter ##8272# you should pop up with a menu. If you have your msl number you can change some setting. If you click edit > others > multimedia and change all the proxy values to 0.0.0.0 that may help with speeds. There is a legit walk through on how to do it but this is all just off the top of my head.
Sent from my SPH-D710 using XDA
Yea, I had already zeroed out the proxy settings. dont know if it helped but i did it anyways.
I'll try other modems as soon as I get a good feel on el29 and might give el13 another try.
thx for the tip tho

Where is the WIMAX!!!??

So im having an issue with my 4G Connection when i choose to use it, keep in mind im a typical flashaholic and ive through a lot of rom's, my phone shows that it connects to WIMAX but there is no data coming through browser doesnt run, play store, facebook you name it and sometimes a i have full bars, has anyone encountered the same issue

Have you tried toggling airplane mode, or a reboot?
yea many times its very frustrating, i am currently in CM9 Alpha 3 and it happened this morning while i was omw to work
I haven't met this kind of case.are you sure that you are right?
yea dont take it wrong but im not a noob when it comes to this its just weird, its been happening for a while now in what ever custom rom i flash
So call Sprint tech support and have them try some steps of their own.
Dont mean to be an ass but what do you think they would solve over the phone, a Factory Reset, update my Profile and PRL, Airplane mode, ive tried all of that

I would flash a modem again, as this did fix my problem when I flashed CM9 and lost data and calls. You won't lose nothing by trying, good luck
Maybe the tower is down? Maybe they will refresh the data from their end? Customer care CAN do some nice things in trouble shooting. Use ODIN to go back to a 100% stock tar and see if it works then!
... please delete...
The issue you are experiencing happen over in the Boston area probably about 4 months ago give or take. So don't panic like I did. I had given up back then, unrooted, and took the phone back into the store telling them my wimax stop working only to find out that all of their phones are going thru the same issue. I would check with the sprint store or ask some one in your area if they are experiencing the same issue.
Me too..

I know this is an old thread but I just got the phone (used) and am having the same problem. It's *stock* JB GB27 (rooted or not) and I have not been able to get any data over 4g even if Wimax says its connected, with an IP address, Gateway, DNS address and says it's active on Sprint. And in a strong WIMAX coverage location. Ping says "host unreachable".
As soon as I turn off 4G, 3G takes over and all is good. To the OP, did you ever discover the cause?
Thanks in Advance.

Wimax sucks even when it is working. Sprint really isnt supporting wimax any longer. What is out there is all you are going to get. If you get it, great good for you. If not, oh well...

That's kinda how I look at it too but I might take up the challenge to try to resolve it or play around with some custom roms now that I am rooted. Maybe go back to Gingerbread and see what happens. I actually liked Gingerbread's app drawer better.

You can try running a more updated rom, such as cm10.1 or gb27. Stay away from any 4.3 rom though, since 4g isn't supported.:good:
Thanks for the responses, so I found something odd when this happens,
I wrote down the stats the phone gave me about my connection, IP,
Gateway and DNS server. Everything checks out as belonging to sprint,
EXCEPT my IP 6.6.2.142. Well, that IP just happens to belong to the
pool of IPs allocated to the US Department of Defense Network!

Is Sprint/Clear's servers possibly mis-assigning IPs???? This is from 2
totally different Wimax areas but I'm pretty sure that the same IP was
assigned to my phone both times.

[Q] New-to-me GS3 WIFI Drops/erratic. Fix??

hi friends this is my first post in GS3 world. We live in a rural area and are dependent on good WIFI service - I do tech work so the WIFI in the hacienda is very robust. All our other many devices love the WIFI rig: 2 ipad mins, one Galaxy Note 1, another older Galaxy, two laptops, one HTPC, etc. Only the new-to-me GS3 has issues with it. The visual indicator on the handset seems to not give an accurate picture, so we keep going into settings and seeing what is reported there... "Strong" signal is usually what displays, but in use, sending messages, making wifi calls, whatever, the results are pretty bad. We're using the stock messaging [google] app and stock T-Mobile WIFI calling app.
I want to say that web browsing is a little better, but can't really give details.
ROM etc:
android 4.1.2
baseband T999UVDMD5
Kernel 3.0.31-1128078
build JZ054K.T999UVDMD5
searching around the web I see a lot of the same complaints but really lousy diagnosis and lousier fixes [turn off 'data'; reboot the handset; call T-mobile... that sort of 'fix']
What is the scoop? Is there an internal WIFI antenna connection inside that needs to be checked?
Is there some elusive patch from Samsung?
Is the rig Channel-sensitive? [some older handsets only liked channel 11, or others only channel 6, etc.]
pls point me to the definitive thread if there is one...
thanks in advance
I'm not sure of any threads with much information on this. I don't recall seeing very many WiFi issues at all with the S3.
Are you rooted? Custom ROM?
If so you may want to try some of the other modems/baseband. Link in my Sig.
Otherwise, maybe try Odin flashing the UVDLJC or LJA firmware.
You say it's new to you, so I'm assuming you got it used. Do you know who you bought it from and did they report any problems?
How does it perform on other WiFi networks?

its all stock now.
are you saying to go ahead and nuke, reinstall stock ROM?
I don't have the option of going down Root66 - we are utterly dependent on WIFI Calling.
Is there a way to stop scanning selectively? that is, when I am on my own AP, there's no point in constantly scanning - there are other very weak wifi AP's in the vicinity and I"m wondering if somehow that causes an issue? my Note 1 is rock-solid. I don't recall a single drop with it in the 6 months I've had it. Most disconcerting is when WIFI calling drops - I've been using T-mobile devices for years and only once did I have one for which WIFI calling would disconnect, restart, and reappear like this. It will drop out, then refind its WIFI connection, then you get the "WIFI is Ready" all over again, just like you do when Rebooting the phone.

Yes, nuke everything. That's the only way we can rule out modified/mismatched firmware as a cause.
root66 is stock firmware with root injected into the system image. So wifi calling will still be there. It's just whether or not you want root.
Also wipe data/factory reset. If using stock recovery, this WILL wipe your internal SD. Backup your user apps with TiBu/RTB, and your internal SD card. Do not backup system apps.
You can adjust scanning frequency with build.prop modifications, but I personally use Tasker to control when it's on and off.
ahh. my fault.
ok, we'll get on it tonight and report back when squeaky clean.

please; need a little guidance
Friends, I successfully nuked the GS3, flashed with Root66, got everything working really well but the WIFI issues resurfaced.
Does the GS3 just have a really weak radio?
Compared to even the most humble Galaxy S4G [old and tired], its WIFI performance is not impressive.
Compared to my personal Galaxy Note 1 running more/less stock ICS, its awful ... annoying, unreliable, glitch.
WHY?
My suspicion is that it has trouble switching/credentialing/authenticating from one physical router/AP to another. In our wifi lan setup we have a common AP composed of 2 routers of different chipsets/mftr. Works dandy on ipads, iphones, windows 8, windows 8.1, my Note 1, older/retired/sold androids, etc. The Galaxy S3 is pretty much alone at having trouble when the physical signal of one gets weak and the second one is available - it seems to fumble the ball. Thus, you try to make/receive/talk wifi Call, and get random drops, retries, reload of the WIFI Calling APP.
is there a fix?
Set static channel?
Set static IP [instead of DHCP/select] ?
Grab inSSIDer from the play store, it'll show you if you are on the best wifi channel for your network.
Try turning off some of your other devices wifi connections. May be that the router isn't handling them all at once very well.
Do you have anything that operates on the Wireless-G standard? If so shut it down. Itll only severely degrade the entire networks performance.
You need to be rooted for this, but try the LJC and LJA modems, others too if your up for it.
Does it exhibit the same problems on other wifi networks?

Thank you for helping!
OK - Let me ask a question [it is rooted - root66 per above, busybox, SU, etc]:
I've used InSSIDer before and moved channels here and there and what I noticed is that the way inSSIDer deals with signal data display, whatever channel you pick, it will show one of the other channels as being "better". switch to that channel, and it will show some other channels to be better, etc round and round we go. maybe I'm not using it right...
as to G-only devices I'll give that a shot - I think one of my windows units may be all G. easy fix.
To me it seems clear: the places where the GS3 goes ambiguous and fails to maintain a connection is where the two AP signals [again, one AP,one login, one authentication type, but 2 physical] are pretty evenly matched, per how WIFI Analyzer displays the data. If I shut off the tertiary router, it will just drop signal when you move a tad too far away which is what one would expect, but the GS3's "reach" is the worst of the lot. I'm hoping somebody has figured out how to get hold of that radio and boost the signal.
I don't have a feel for how it does otherwise - we are dependent on WIFI calling at home/office - when out and about its the usual drill... sit in the right spot at the restaurant and you're good.
Those modems you suggest: do they support T-mo WIFI calling APP ?

As or inssider, or any similar app, I don't go by what it says is the best channel. I simply look for the channel that has the fewest networks overlapping it. It probably tells you a different one us best each time because its taking into account that there is now another network on the previously recommended channel, yours.
If you have a single G device on an N network, it'll slow the entire network down to wireless-g speeds. So yeah, shut down that machine and ill bet you see improvements across the board. (You may need to reboot the network and other devices)
If you have one router and one AP but both with the same ssid and pw that may be causing your problems. With this type setup there's no way to really be sure which you're connected to. You may connect when close to one, but when you move away from it and closer to the second, it won't connect to the closer/stronger one automatically. Even if you turn it off then on again, it may still connect to the first if the signal is strong enough, even though there may be a stronger one available.
Try having it connect to the ap using different credentials and then you should have greater control over which you're using at a given time.
Allthe modems should function properly with everything they are supposed to, so yes they'll all work for wifi calling. I was looking into a way to adjust the Tx power for wifi a long time ago. Ill see if I can find what I was doing and try again. If you use a 3rd party router firmware (dd-wrt or tomato), you can adjust Tx power on the router itself if I remember correctly.

in reverse order:
- as to to the wifi device power/range I was speaking of the phone/handset, not the router. But since you mentioned: I have not found an N or beyond router that has GOOD open source; open-wrt, dd-wrt, tomato et al - if you really read carefully what the feedback is, a lot of them suffer bad speed degradation. the old wrt54gl's would run full-tilt G speeds, over a wide range, and last for many years, but I have not found the equivalent in any other device running or capable of running one of the good [or formerly good] open-source codebase
- Are you sure about that client-bridging common-ssid/pw/encryption? the whole point of such firmware is to make the transition seamless and it is for every device except the GS3: two ipad's, one Galaxy S4G [999v], one Galaxy note T879 [debloated stock ics], two HP workstations, three laptops - gateway, thinkpad, hp Envy - not one of those devices gags when switching router signals. only the GS3. with the other devices, you literally forget that you've got multiple routers
The GS3 code has multiple network notifications also that the other two Galaxy's do not: it interrupts your blasted work to INFORM you that you're signal is dropping [how dumb is that?] - then it informs you that you've been disconnected, and informs you that you're "not registered on the network", then it informs you that it is logging in again, then it informs you that WIFI Calling App is ready for use as though it was the first time you used it.
- I will give the modems a whirl. I'll stash a full nandroid and try them out - If any of you happen to have a link to the 'how to' steps pls pass on as it will save me a lot of careful reading.
oh, and I was wrong about G-device; i replaced that one with an N device. Frankly, G speed is way fast enough. my internet connection is only 20Mbps so if I had the old WRT rigs back and up/running it would be PLENTY fast. Mixing B with G... now that was a real problem - there you were talking about effectively 1 to 5 Mbps

I havent used any 3rd party firmwares for my networks in a long time. I was assuming that for the Wireless-N routers, they would have come a long way and solved a lot of their issues by now. My mistake.
I am sure about the router/ap setup. (Is your second set up as an Access Point or Repeater? Either way the same issues can still present themselves) I refer you to the following website for information on this and a little bit to back up my claim. It may be worded better or easier to understand than me, but either way its good info.
http://www.smallnetbuilder.com/wire...w-to-add-an-access-point-to-a-wireless-router
Step 3 is where this is touched on.
I have to be honest that I am skeptical that your other devices are transitioning over to the AP. (im guessing they are ALWAYS connecting to the AP) Unless their radios are actually much weaker than the GS3's. In fact, what I suspect at this point is that your GS3 is trying to connect directly to your router all the time, while your other devices are connecting to one or the other, all of the time. This is one of the draw backs to using the same SSID, it is difficult to tell which you are actually connecting to.
Read over that linked page. Let me know what you think.
Will do. thanks for that.
if your theory is right, on any one of the frequent auto-disconnect cycles, you're saying that the GS3 will connect to which? the stronger one? any idea how the firmware is setup to pick a winner?
Also, webbing around for answers [there are a LOT of threads on this issue as it turns out], there's a good deal of discussion about 5ghz vs 2.4ghz bands, and that samsung/t-mo have changed how the firmware handles transitions [or connect/disconnect] to one or the other. i.e. https://support.t-mobile.com/thread/37707?start=0&tstart=0
I can set my routers to one or the other if that would help - Any ideas if one is preferable?
Ever heard of GS3 being "channel sensitive"? I have not. Early WIFI/WIFI-Calling capable models from several mftrs were quite channel-nitpicky.
I could easily check that transition [seamless dropping of one, connecting to another] if there was a way to verify the MAC of the connected ap. know of such? I can't find much in the way of advanced settings but I have not a guide to the keyboard/manual settings methods for this build 4.1.2.
read the article but see no discussion of your point.
pick the right link?
the setup I'm using is simple wireless bridging - no physical medium between the twain. subordinate router has the mac address, encryption type, ssid, credentials and channel setting of the boss. reboot and done.
pretty much the same type of bridging as with DD-WRT [though it has a lot more options... more confusing]
I really think that the GS3 modems aren't that good, especially when it comes to wifi calling. My family and I haven been having some bad signal problems as of late so we've been relying on wifi calling to make calls. I had a lot of dropped calls in the past but I knew that had a lot to do with the old modem/router setup I was using. I would lose internet connection not matter what I was on. The internet would just drop and then reconnect, very frustrating if you were on a call or playing Xbox live. so last week I hooked up a new Comcast modem with wifi. The drops stopped but I still have to literally be standing right next to the modem if I wanted to make sure I didn't lose a call. If I walked into the kitchen, which is 15ft away, I'd get the little beep that warns that I'm about to lose the wifi signal. I know my signal that's coming from the router is good because all my devices, including the phone says so. Hell, the kids across the street asked if they could have the password because their internet was shut off and my signal is strong over there.
I don't have anything technical to support what I say, just experience but that experience tells me that Tmobile's wifi calling doesn't work that well unless your within 3 ft of the router.

Accorfong to my research it'll try to always connect to the first one it connected to. Even if the signal is stronger on another. That's the main point I was linking to that article for.
As for which band to choose, 2.4 is usually best. 5.0 is faster, but with a shorter range and more susceptible to interference.
tmob removed the option as you can manually select which you prefer. There is an apl I include with all my roms though that'll give this option back. Let me know if you want the link, though I doubt it'll help ypur particular problem.

read the article but see no discussion of your point.
pick the right link?
the setup I'm using is simple wireless bridging - no physical medium between the twain. subordinate router has the mac address, encryption type, ssid, credentials and channel setting of the boss. reboot and done.
pretty much the same type of bridging as with DD-WRT [though it has a lot more options... more confusing]

Ok, so its more of a repeater setup. The routers are not connected to each other via Ethernet or powerline?
Step 3 of that article is what I wanted you to read. Its on the 2nd page. (Though I do suggest reading the whole of both pages)

I really think that the GS3 modems aren't that good, especially when it comes to wifi calling. My family and I haven been having some bad signal problems as of late so we've been relying on wifi calling to make calls. I had a lot of dropped calls in the past but I knew that had a lot to do with the old modem/router setup I was using. I would lose internet connection not matter what I was on. The internet would just drop and then reconnect, very frustrating if you were on a call or playing Xbox live. so last week I hooked up a new Comcast modem with wifi. The drops stopped but I still have to literally be standing right next to the modem if I wanted to make sure I didn't lose a call. If I walked into the kitchen, which is 15ft away, I'd get the little beep that warns that I'm about to lose the wifi signal. I know my signal that's coming from the router is good because all my devices, including the phone says so. Hell, the kids across the street asked if they could have the password because their internet was shut off and my signal is strong over there.
I don't have anything technical to support what I say, just experience but that experience tells me that Tmobile's wifi calling doesn't work that well unless your within 3 ft of the router.

Make sure you don't have a bottleneck somewhere on your network. (Such as a misconfigured router, a docsis 1.0 cable modem, etc.) Or as I stated before, if you have a wireless g device active on your network, it'll force the whole network to degrade to wireless g speeds. Also use inssider to check if you are on the best channel. And check for any points of interference. (Microwaves, cordless phones, power hungry appliances, etc)
If your cell signal went south recently, it may be due to the work tmobile has been doing. What worked best before, may not anymore. Try out the many other available modems to see if it improves.

Thos is a copy/paste of the text I was referring to.
(Starting under step 3)
But most wireless clients are very "sticky" and tend to stay associated to the first AP they encounter,*even when APs with stronger signals are available. So I recommend setting a*different SSID*for the AP, so that you can manually control connection.The other advantage of setting a different SSID for the AP is that you'll be able to see both the AP and your main wireless router if you're using the Wireless Zero Configuration utility that is built into Windows. Even in Vista, Microsoft has stubbornly chosen to not show multiple wireless networks that use the same Network Name / SSID.
4) Set the AP channel
One large network practice that you*do*want to follow is to set the AP to a different channel than the main wireless router. In the U.S. you should use only the non-overlapping channels*1, 6 and 11. So if your main wireless router is set to channel 6, set the AP to either 1 or 11.You should probably do a quick site-survey first (see this HowTo), to make sure that you aren't setting the AP channel to one used by a neighbor's network. If you can't find a completely clear channel, choose the*weakest*neighboring network and set the AP to its channel.

I'll look into it.
Thanx
