Signal, 3G, 4G Network Tweaks - EVO 4G Q&A, Help & Troubleshooting

I have flashed all the latest radios and do so every so often when I flash a new rom. I just tried out Ava V10 rom and in the changelog it says 3G and 4G performance tweaks and tower preference tweaks. We'll in my area (suburb of chicago) I actually noticed a decent increase in reception and 4G/3G speeds.
I was wondering if it was anyway possible to take these tweaks and apply them to another rom? Thanks

I'm interested in the topic because my 4G speeds while tethering are low (30-80KB/sec) even though I have full bars of 4G. I'm in West Palm Beach, FL. I know higher speeds are possible! When I tether in 3G I get 15-80KB/sec.
I tried the guide here with no change in speeds.
I followed this guide as well but my settings were already at 0 (for the port) and 0.0.0.0 (for the proxy address).
When you type ##3282# there is a menu for "WiMAX", even a sub-menu named "bandwidth", I figured maybe something was possible...

I found this here which is entitled "Boost your WiMax 4G Speeds..." It has 2 tricks you can use. Post #1 and #7
Here are the default ##data# settings in case you screw something up.

Strange 4G behavior - beyond speed tests

I have been feeling out my 4G connection for awhile now, and I am still having a strange experience with it. Speed tests always give good results, but actually using 4G for daily tasks is not working out well so far. Often times it loads pages and market or maps slower than with 4G...
I had been having this off and on all week, but I thought it was just my poor 4g connection at home. Anyway, now I'm writing from a mall with a very strong connection. Now I'm noticing when I load a page or open maps/market, it actually disconnects from 4G and loads with 3G for a second or two then switches back..
I've been using fresh, dc, and bugless ROMs, and always with the latest radio. I've had to apply the 4G patch a few times to get 4G working, but once it's up, it behaves the same...
Is it the ROM, my phone, or the nature of 4G in philadelphia?
I'd guess it's the nature of the 4g. It's still a new market. One thing, the bars on your phone only show the connection to the tower, not the connection to the internet. My 4g has been like that in places around Dallas, but closer to the heart of Dallas, I get more consistent connection. Someone correct me if I'm wrong, but that just seems to be the nature of technology here on the bleeding edge.
I might add, that for whatever reason, I cannot load my XDA bookmark to the evo 4g page on 4g at all, but it loads fine on 3g or wifi. I have yet to understand that one. Other pages seem to load ok though.
I've also noticed issues on xda, I think it's related to flash. I noticed if I load flash only sites on 4G it never loads or takes a stupid long time... If I cut to 3G it loads fine... On xda, it's the flash ads..
Having the phone process information and display it is much different then just doing a speed test. I'm in Philly also - but only use the 4G for tethering.

I agree completely, but the issue is that, on some pages (usually with flash) It loads and displays the information faster on 3G than on 4G... I'm not sure what would cause that. I'll try tethering and see if it's the same... I'll also try 4G when I'm in central philly...
I wonder if flash determines what quality to stream the content at? Like if you use sprint tv on 4g you will get higher quality video but it can be laggy trying to catch up to the stream. When on 3g the quality is a little less but doesn't skip around at all.
I'm having similar issues with my 4G connection. Some pages won't come up. The progress bar loads up to about 50% then either takes a really long time to bring up the page or not at all. All I get is a blank page. The xda forums are one of the sites I'm having problems with also. It loads up fine over 3G and WiFi. I'm currently running the OMJ rom, latest Radio, and the Fresh 4G fix. I'm not sure if the problem lies with my rooted Evo or the 4G network.

That makes sense to me. Still, it seems strange that the network or phone one struggles to keep up like that. Ah well, like I said, the nature of things out here on the bleeding edge.
i have experienced similar 4g/3g flipflopping behavior and pisspoor wifi. its like the radio is very slow to get a connection as coming out of the pocket and then while in use it will go to 3g then say it's found a 4g and get on that and back to 3g. sometimes i'll see 4g w/ full strength but am unable to do any internet functions (web browser, pandora, meebo, appbrain all fail indicating no network). by putting it into Airplane mode...count to 3...take it out of airplane mode the radio reconnects and is able to pass data as expected.
i have done full cache, delvikcache, (and the other whatchamacallit) formatting between builds. and cleared the cache after updating the radio (even tho i shouldn't need to for Fresh .3)
i have not fussed with App2SD nor anything Flash related.
not sure if i live/work on the "edge" of coverage or if it's EVO (software or hardware) related. I"m leaning more to the coverage at this point. between testing it more as i move around town and next weeks froyo builds maybe the 4g gods will shine down upon me.
Increase WiMAX_Idle_Sleep(s) setting
I had the same issue and found these instructions which show how to increase WiMAX_Idle_Sleep(s) setting.
hit ##DATA# > Edit mode.
Put in your msl code
Chose WIMAX
Scroll down to Wimax_Idle_Sleep
Change the value from 10 to 300.
Click menu, commit changes and restart the phone.
See ' [GUIDE] Easy way to get MSL without calling Sprint or using CMDA Workshop' to get MSL Code, or just call Sprint and ask for it.

I work in Philly and have the 3g 4g connection problems too. Your fix did not work for me. No matter what Rom or fix I've tried I can't keep a stable 4g connection without the stock Rom flashed. Sometimes WiFi tether will work on 4g with a custom Rom but anything else and I have all kinds of connection issues. I don't think its the network because 4g connection cards work just fine.
Edit: my main cause of concern is that simultaneous talk and data. I like to be able to talk and still follow sports scores while working. Sticking to stock for now.

4G Constant Scan - connect/disconnect

I have tried to search but it doesn't like to include 4G (to short to be included) in the search box so forgive me if I wasn't bright enough to find this somewhere else.
My EVO will scan for 4G service. It then says connecting to Sprint, then flashes disconnected and scans again only to say connecting to sprint. Rinse and Repeat this process over and over. I have had this issue both on clean installs of fresh rom and currently on Koni's elite series rom. Anyone have this issue as well/and or know of a solution.
I do have a 4G MAC address so I would think that I should be able to connect.
Thanks in advance for the help

Well for one are you in a strong 4G coverage area?
Try shutting off your phone, pull the battery for a minute or two and restart your phone. (If you call Sprint and tell them this issue - this step will be the first one they tell you to execute)
Also you can try updating your profile and PRL, When I am having weak signals under 4G/3G - I update my profile & PRL and it always seems to fix the signal issue...
hope this helps

this happens to me when trying to connect to a 4g signal from my apartment. it will say "scanning... connecting... obtaining IP address/disconnected/scanning...connecting..." (sometimes the "obtaining ip address" does not appear) yet if i try to connect in other parts of town it connects fine. wimax sucks as far as connectivity, so until more towers appear and the signal is better there's probably no way to fix your issue. ive tried every inch of my house, and of course by the windows is slightly better. if you can manage to get a "poor" or "fair" 4g connection you'll probably end up with slower speeds than 3g anyway. it's really misleading because the software indicates the phone is trying to connect even though the signal isn't good enough to maintain a connection. clear and sprint coverage maps indicate my address and neighborhood as "best" 4g coverage too, so i have little hope of this ever improving. there is a thread for updating your ##data# values to get the phone to connect sooner and stay connected longer which i think probably helps, but not enough for me (nothing you do on your end can improve the tower signal) and even if it did, like i said you're connecting at "poor" or "fair" signal and your data speeds will often remain slower than 3g.

I am good coverage areas, my work where I am now can get it in buildings and comically my home is exactly on the line of in-home/on-street. Tried pulling the battery to same results, I think I have current PRL 60675 PRI 1.90_003. Not sure what you mean for the profile though.
Thanks for the tips.
I can connect to 4g with a poor/fair signal now, and heres how I did it if anyone cares:
flashed joeykrim's rooted stock sprint rom (5.1 I think)
updated prl through settings menu
updated profile through settings menu
use msl reader app from market to get msl code
go to dialer and type (NOT call) ##DATA#
enter MSL, go to edit mode, tap the first out of the 5 or so menu items
press menu, choose "restore" (phone will reboot or power off)
turn phone back on and enable 4g with phone on window ledge.
somewhere along the line (flashing many many different roms and wiping a lot, trying various kernels and tweaks) I had gotten stuck in the seemingly irreversible 4g/wimax connection/disconnection loop. Now I can at least connect!

I seem to not be getting the best signal strength as i was before is that a commen problem with this rom??? i use to have great signal when i was on stock all the time at my house

Keyword there is "seem". Every rom uses different algorithms to determine signal strength. One bar on one rom can be the same signal strength as 6 bars on another. So basically, don't trust the bars.

That definitely is a good point and needs to be taken into account, but that being said, I used a little tweak I found over at HTCevohacks.com to boost my connections. Basically just bypasses the Sprint proxy and speeds things up a little bit.
I will copy and paste the instructions below, all credit being given to HTC Evo 4G Hacks.
Before doing this though you'll need to flash a sprint sense rom or else this method doesn't work.
First, install MSL Reader app from the Market (yes, it’s free) and find the MSL of your HTC Evo 4G or 3D.
Then call ##3282#.
Choose “Edit Mode”.
Enter the MSL code you got earlier for password.
Then goto Advanced->RTSP/HTTP Setting.
Then set RTSP proxy IP to 0.0.0.0.
and set RTSP proxy port to 0.
and set HTTP proxy IP to 0.0.0.0.
and set HTTP proxy IP to 0.0.0.0.
Choose back button, menu button, and hit “Commit Modifications”.
This should get your Evo 4G or 3D rebooted.

You aren't actually "boosting" your signal. You signal is the same as it was before the hack. That hack just bypasses sprint's proxy's when streaming media, which is the ONLY time you will see a difference with that hack
The signal bars on the stock ROM do not accurately represent your overall signal. It only shows call quality signal, not data. CM7, and many other ROMS, use a more true representation.

I understand that haha... I don't see why I can't call it a boost seeing as I explained in the post it bypasses sprint's proxy. All good though, thanks for helping people clarify.
Thanks for all the response guys i did some reading on it that day found most the crap out

[Q] Force EVDO Rev0?

Hey everyone, I'm not sure if it is possible, but does anyone know of a way to force the modem to use EVDO rev0 instead of revA?
I'm noticing on my speed tests that I am getting faster speeds at my house when the network is shown as connected to rev0 rather than revA.
Thanks
i notice the same
If your talking about using 1x instead of 3G I have noticed that as well, there just isnt a simple way of doing it. You can try ##debug# in your dialer, type in your MSL, go to others select HDR/1x selection, then select CDMA only mode then press ok then you will always be on 1x
hmmm.. good observation
Rev0 and 1x are not the same plus when 3g roaming it uses rev0 too
Sent from my Unnamed 2.0.1 EL29 powered Galaxy S2 brought to you by Sprint
Yeah I'm not talking about 1x/3G, I'm just referring to 3G. I remember on my old Touch Pro 2 there was a way to disable revA, but I can't find it on this phone.
That's interesting I never new about that.

[Q] N900T: fixes for poor signal?

My N900T has much worse signal than my previous Note II - between 15 and 20 dBm worse, so essentially unusable out in the fringe area I live in.
I'm running SlimKat 9.0 (4.4.4) baseband is N900T UVUENK3 (which I think might be the most recent modem).
I'm using a StraightTalk ATT SIM (phone is unlocked) but that shouldn't matter for signal strength
I've got Preferred network type: LTE
And in service mode / phone info, I have preferred network type: LTE/GSM auto (PRL) - unchanged from standard.
I've removed the back cover (the one under the battery door) and made sure all the "fingers" make good contact with the contact pads that are built into that cover (fixed my GPS but not baseband)
Anything else I can check? Should I try some ATT radios to see if signal improves?
Or is this just the nature of the beast? Move to the city or get a different phone?
Thanks for any input!
Had this problem but hopefully the fix I used will work better. I flashed pac rom from nightly and resulted in no signal even though showed 3 bars(never higher or lower) but no connection in reality. Tried this and got signal kinda ( very slow and missed calls and sms)
Anyway
On tmobile network but might help either way idk never had att.
First goto
Settings/More Networks/...
Then first try the lte if not heard using 3g can fix signal connection with custom roms.
Check your apn settings and verify with att/simple talk
And if needed hit the mobile operators and let it do its thing.
Still not working can try fixing another way let me know.
Screens attached and can't post link ig but quick Google search should net you the setting. I did keywords "att apn settings"
Let me know how it goes. Flashing pac rom see how update goes this time for me lol
The signal got a good bit better when I replaced the antenna signal cable. Cost a whole $3.
I'm still 5 or 6 dBi down from my old note 2, but, from my forum reading, that might be the nature of this beast.
I have same problem, poor network, and sometimes when I go to some club or cafe I dont have network and on S2 same network I have full signal 3G, H+
