I am experiencing slow WIFI Speeds of 54mbps and dropping to 18mbps in some cases. I've checked my router and the problem doesn't rely there.
If anyone has a WiFi patch/fix of somesort to get Wireless N speed, please share the link.
I am using RCMix S V2.0.1 ROM
Many thanks.
Maybe your SD Card is too slow to write more than 1.8mb/s ?

? I'm talking about WIFI speed, how is SD Card related?
there are patches that enable WiFi N but i think they are rom-related.
like the one baadnewz did for insertcoin (downloadable as an add-on from his webpage)

Well you can even have 100mbit WIFI speed, but when you are downloading something to the SD on the Phone it's limited to the write/read speed of the SD Card.
Correct me if im wrong lol.
For example i have Wireless 'G', but i can get around 1.3mbps max download speed because ****ty sd card.
Hope you know what i mean.

Your right since downloads are stored and used as cache on your SD card. You should think about getting a genuine class 10 card if your a fan of speed.
If you would like to do an internet speed test then use this site http://www.speedtest.net/ or install the app on the android market.
Oh and wireless N is enabled in the latest Gingerbread update according to a few reviewers, not that I've reviewed this myself but will do when I install the update.
I thought hardware wise the Desire only had b and g, not n. Or am I missing something about the patches?

I know... I'm baffled about this one too mate
The newly released GB from hTC has wifi b/g/n as stated on the hardware page under the settings. The hardware has alawys supported n, they just haven't enabled it untill now. In real life difference isnĀ“t all that big. I get 22 mbit/s now instead of 15 before. This is with a 100 mbit connection through a dlink dir655.
I am using 802.11n for quite a while. The speed is good, and compare with 802.11g, there is definitely difference in throughput.
I have the rom Reflex v1.2.7 and has WiFi n as can be seen in the attached picture. I found speed difference switching from Wifi b/g to Wifi n use whith a n wifi router obviously......
How can you tell if you have b, n, or g wifi and what's the difference? System info doesn't show this info.

Yes, but that doesn't mean to say it's logical though. It may just be that in his case he found it was faster but the difference between them may be something else and not based on speed.

I know this because I have configured my router as well as can be seen in the attached capture. This router lets you set automatic modes or set only b, g or n mode and I configured Wireless n.
On the other hand, when I check work perfectly otherwise the signal gets weaker ....

IIRC, there was an article (forgot where ) comparing handsets like Desire, Galaxy S, iPhone and Torch...
I recall them testing both download and upload...
On average all of them hovers around 12-20Mbps mark...
I found that the wireless n patch is still available on mediafire: mediafire(dot)com/?34oo489d9roqf#4g812p9sfh8iy
Am I right in thinking that since desire ROMs are still using the old kernel that this could be used somehow with a 4.0+ ROM?
Not enough posts for links -.-

The value displayed in the picture comes from a text entry in the build.prop of that ROM. You could edit it to say "802.11greencheese" and that's what it would display. The only way to truly tell is to get your Access Point to display what rate the connection to/from your Desire really is.
I think I necroed a thread, doubt there's people expecting post replies now

Hey There,
I've just installed this fine ROM today, and it seems great,
but for some reason, the wifi reception is BAD now.
It works fine if I seat near my router, but if I move 3 meters away
it looses the connection ... and says the reception is POOR.
Any1 else has this problem?
Which version of CM10 did you flash, if it's anything older than beta 1 try flashing Beta 1 ? if you still have problems after Beta1
Try flashing a different kernel and see if that resolves your problem. (if i can spare you some time, try faux123's kernel)
http://forum.xda-developers.com/showthread.php?t=1647993
And then if you still have problems.
Try running the Viper ROM 2.6.0 with the Butter hacks runs very smooth.

Thanks for the quick replay
I flashed the "[08-09] [ROM] CyanogenMod 10 - Endeavor Unleashed" rom.
I don't think this is the same cm10 everyone's using.
and I don't really understand, doesn't the Kernal comes with the rom?
Can I change it without changing a rom ?

I notice the same problem a few days ago (I think is since I have install CM10). I have switched on OrDrost since 2 days, I tried the Faux kernel and finally I just revert to full stock rom and my wifi signal haven't change :/

But on the stock rom WIFI was ok.
Update: Ok I did the "Squeeze" test. Wifi is great whn I squeeze
So it is a hardware problem?? How it only started after I put CM10?
Have you reinstalled the stock rom since you have the problem?
I don't know if CM10 is the cause, or it's a coincidence..
there's an UNOFFICIAL release at the moment which may fix some issues, though I've not noticed anything and I've had every release since A10 installed, so it could be a hardware issue.
I'm on the newest build of cm10 and my WiFi network is fine. I can from leedroid and so far just the same. I do have a tiny bit of earphone cable between my back and hard case which gives me my full bar due to the hardware fault.
Couldnt be bothered sending it back. So this works. Bit did recorded it with HTC so they know I have the fault.

Not yet, I really hate the stock rom.
tgcp, Where can I get this rom?
(Although it really seems like an hardware problem,
I heard the latest stock update helps a little so there
might be a software solution)

But if you use Cm10 without that little earphone cable, the wifi won't work good?
BTW, what does htc support ask to fix the problem? Do they care you rooted and unlocked the device?
The cable is about 3mm in lengh and as i have a hard case, its enough to compress the connection inside the phone where the fault is.
Htc would of course fix it, but whats the point if the phone is working and its not noticeable.
I would have had to relock bootloader and go back on stock rom.

I can't move more then 2 meters from my router or it disconnects.
Does your wifi issue not that bad? (without the cable's help)
With out my fix the signal is a joke. 1 bar when 3 feet away. Wasnt usable.

Problem is I can't get back to stock! from what I understand the Stock RUU for my phone wasn't released ...
Do you think HTC will be "understanding" and fix the wifi issue even with a custom rom?
(they'll know anyway that I opened bootloader)
Try flash the Rom with the stock kernel, that will surely solve the WiFi problem.

Did you not do a backup before installing custom rom. Im positive that even if you relock the bootloader they can see that if they went in to recovery. But unlikely. So if you flash stock rom and re lock bootloader, remove root you should be fine

Hi, try using tbaldens CM10. It can be found under HTC ONE X ORIGINAL ANDROID DEVELOPMENT. I found this to be the best CM10
I have been chasing this problem ever since installing CM10 on my Evo 4g LTE. I was getting 4 times the wifi distance on the stock rom. I go about 30 ft. outside the office and wifi drops. Also, what is the most annoying... I stream over our LAN, and when the screen is off, it turns wifi off after a few minutes. (and yes, the check box is checked to keep wifi alive). I've also tried all of the wifi fix apps and none work. If I leave the screen on and stream........ it is good anywhere from 1/2 hour to an hour, then it will just stop. This kills my battery of course. The problem 1st occured when I first bought my OEM 4g lte, but there was an option in the advanced menu "best wifi performance", after checking that, it worked great, then I switched to CM10 and I now have the wifi issue, and there is no option for "best wifi performance". I've tried a couple other jellybean roms and they have the issue as well. This is driving me nuts. I hope someone finds a solution. I don't think the average person would find this as a problem, but when I stream over the net and move all about the shop, it is unacceptable.
I faced the same issue but not on any other ROM. It was specifically with Cyanogenmod 10. I was upset because it gave me the best results but the wifi result was really poor.
However, since I work with wireless networks often, I decided to explore Cyanogenmod's wifi settings. I noticed that if you go in the Advanced Wifi functions (which you can find in the Wifi options menu) you will notice that there is an option called "Wi-Fi Region Code".
Apparently, this option allows you to select the frequency bands your device can operate and is subject to the different world regions. It is quite possible that your Access Point follows the regulatory body of your country and you should know which frequency bands they allow the AP to operate. Due to this it may be just that the Cyanogenmod, by default, put you in a different regulatory domain and limits your frequency band to a subset offered by the AP. Hence, this effectively limits your wifi reach even if you are sitting right next to the AP.
I chose "Japan" since I remembered that their regulatory domain allowed for quite a large subset of frequencies that are allowed on the WIFI spectrum. This immediately increased my received signal strength and I did not have any problem since.
I suggest you play with this, it is likely that your android device will start functioning correctly. However, if you are facing this limited frequency issue on more than one device and that too running different operating systems and different wifi hardware...chances are that your wifi router is malfunctioning. In that case, replacement or repair of the Access point is the best alternative.
Good luck. I hope this solves your problem.

I've tried changing my Region Code, but for some reason it keeps defaulting back to Europe... Any ideas? I've tried changing it numerous times, same result.
I've seen a few similar threads to the one I'm about to make. I've tried different suggestions which I will post here. Yet, none of them seems to work and I'm curious to see if anyone of you has a fix for my problem. My phone is an unbranded international HOX using the 9.7.2 ARHD rom by Mike1986. Here we go:
Problem
While being on WIFI my push notifications aren't coming through in time. There's a delay from anywhere between a few minutes up to as much as 40+ minutes. The phone doesn't have this issue being on the mobile data network. I'm also not 100% sure if the delay is still there when I'm on an different router. Even when I turn on the screen again, the messages seem to come in randomly.
Settings
WIFI best performance enabled
Static IP by router
WIFI sleep policy: Wifi always on
Tried suggestions
Wakelock: One thread described using an app called REGPON keep-alive, which installs a wakelock onto the phone to keep the data connection alive. This app did not do the trick. It only drained my battery and the messages still didn't come through.
Wifi performance: Set the phone to maximum wifi performance. This seemed to work for a while but ended up not working proper either
Kernel: Try a different kernel was one suggestion. I've switched from Stock to Faux123 010 kernel. This didn't change anything about the WIFI problem.
Static IP + Portforwarding + Disabling router Firewall: I've tried both port forwarding on port 5228 and even the range 5224-5228. I've also tried setting up triggered ranges. Maybe I'm doing something wrong on this part though. The router firewall is disabled and it should no longer block anonymous WAN packages.
Disable SmartSync: With the Suite Tools that are included in Mike1986's rom I've disabled Smartsync. No results as far as the wifi problem goes.
Probing app: I've tried an app that supposedly probes my router at least every minute in order to keep the connection alive.
Switching between b/g/n network: Didn't make a difference. The signal quality of the router is also good.
The only thing that did work for extended periods of time was using this remote control app that allows me to type through my PC keyboard, where the text ended up on the phone. I've also got an app installed to test push notifications. It's capable of making a log. Maybe that'll give you guys more information.
Right now I'm not sure if it's an issue with the HOX or if my router somehow stops the traffic. I don't recall having this problem on my HTC Desire. Does anyone have anymore tips?
Thanks,
Zendio
No problem with Gmail push notification on Stock 2.17.401.2.
Yesterday I still was on ARHD 9.7.2, also there I never noticed any delay.
Edit: this complies to various wifi networks (@home, @office, @parents etc.)

I am so sorry to hear you are affected by this problem, but also happy someone else is experiencing the exact same thing as I am !!!
I have tried different solutions to no avail.
Would love to hear something on this topic !!
Also I should note, I don't have any kind of task killer installed.
In general use WIFI feels really fluid and responsive. I really have no idea what could cause these problems.

I hope so. My One S is experiencing the same thing. I've tried everything above. No luck. Some stuff is fairly critical that I get it as soon as it comes in. I might try getting ahold of a Nexus 4 and do some testing with its wifi, just to make sure it isn't a general Android problem.
What router do you have? My issue was any android device in the house. Turned out it was my router, I put a custom firmware on it and all my trouble have gone away. My friend has the WiFi issue on a virgin media superhub.

I have an Asus RT-N66U. Funny you should suggest that. I'd planned to throw Tomato on it tonight and see how that works out. I did some tests at my folks' and their router had the same results. It's some cheap Netgear thing. Not sure of the model at the mo. I'll post back with results. If not tonight, tomorrow some time.
No go
Well that was unsuccessful. Actually it slowed things down. With the default firmware I get notifications from the instant I press power to wake up my phone. With Tomato there was a second or so before I got them.
Time to try DD-WRT tonight to see if that does the same thing.
I have an rt-n56u so the older version of yours and I'm running the Asus wrt that is being made, its fixed all my problems and is awesome tbh.

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?

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?

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 ?

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?

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.

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)

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
ok, googled the past couple months with no results. searching here still no results...
my s3 seems to have sluggish wifi wherever i go, no matter what modem, no matter how many settings i changed advised by posts ive found. *#0011# turning off psm does not work. changing advanced settings will not, static ip does not, flashing roms tw or aosp only same results in all.
im beginning to think this is a hardware problem, not software. cant get a new one cause i don't find it a need for insurance cause if something breaks its cheaper to fix ordering online, plus the fun doing it yourself.
does anyone know if we ever had a flash-able zip to fix like the international version? tried and bricked of course. or any steps that i haven't posted i didn't find searching?

Is it a newer one or an older one? The reason I ask is because all S3s are not built the same. I've had mine since they 1st came out, and have never had 1 issue with wifi speed. I just rooted a newer Sprint 1 and a Boost 1, both of them had wifi issues even after I set a static IP for each on my network.

its the newer build. forgot to mention zeroed out some of the http settings in ##data# for the speed boost. 4g zips.
i cant even find a diagram online to find where any wifi chips are located. went as far as taking a heat gun to the board itself and applying weight to it after like the famous ps3 fat fix. yea, i went that far lol:silly:
