[Q] Wifi Problems. - T-Mobile, Samsung Galaxy SIII

So i've been running on Stock Jelly Bean 4.2.2, using Roms such as CarbonDev and ParanoidKangdroid. I had been running on CarbonDev for about 3 weeks when suddenly i ran into wifi problems. Sometimes the wifi indicator would be blue or grey, but it would just not work. Anything in the browser would get stuck at around 10% loading and then display unable to connect. Nothing in the Play Store or Youtube works, it just shows the spinning circle. After this, i tried completely wiping and trying the same ROM, wiping and trying different AOSP ROMs, wiping and trying Touchwiz ROMS, but nothing worked, the same thing always happens. I've also tried setting it to only accept 2.4 Ghz or only accept 5 Ghz, turning off wifi power save in service mode when using a TouchWiz ROM, and wiping the cache and data of the Google Services Framework application, all to no avail. I didn't drop the device or put it into any kind of abuse either. Has anyone else suffered from similar problems or know how to fix it?

Seems like your wifi is screwed. Try to odin to full stock rom. Otherwise you have to fix I guess.

Where can I get full stock ROM for my sgh-t999VVLLH2

[Q] Kindle Fire wi-fi keeps dropping

Hi,
I'm running the latest CM10 (Linaro). My Wi-Fi connection constantly drops for a few seconds then reconnects. It was doing this on CM9 as well. Not sure about what it did when stock (wasn't stock for long).
Is this an issue with the Kindle, or with the rom(s)? Is there a hardware update? Any help would be appreciated.
Thanks!
mike
Seems to be a common gremlin with custom ROMs. There are a few that don't drop, or as often. Gotta test em all.

Thanks. I just did a full wipe and installed [ROM][10/10/2012] Unofficial AOKP Jellybean Build 4.
Same problem. I suspect if I went back to a stock rom, the wifi issue would disappear. But no way... this Jellybean build is fricken awesome.
Might a different kernel help? Could it be that I just have a lemon?

This sounds like a hardware problem. While there have been some wifi issues in the past, these have been resolved. Dropping constantly is hardware. Reload stock and exchange it with Amazon.

I installed the stock rom (MoDaCo Custom ROM). The wi-fi seems to be working great.
Maybe I'll just leave it stock. It's not so bad once I put Go Launcher on!
- Update - I did a thorough wipe of everything, installed the latest CM10 (SEMI-NIGHTLY] CM10 + 4AI.1.7 KERNEL [STABLE). WiFi seems to be working properly now.
Thanks,
Mike
Mine is/was doing this on CM10 SGT7, but I think it's application specific. Some apps kick the wifi off constantly, like every 20 seconds, while it can stay on perfectly fine on others. If I shut down all apps I seem to stay online just fine. I'll keep experimenting and see what is doing it. I'm also wondering if it's a combination of the KF and my DIR-655 router, which doesn't like some devices anyway and maybe just has a conflict with this one for some reason.
Anyway I'm going to keep testing the SGT7 before wiping and switching. I'm also going to wipe and reinstall SGT7 because if it was really a ROM-specific problem it would probably be identified as a problem for a lot more people using those ROMs and be listed as such.
I'm guessing it's a problem that some versions of the KF have, but is also due to a few specific apps and how they access data. I just hope it's not Chrome that's doing it.
WiFi Drops
I'm running straight up Hashcode's ROM 4.1.2 / Kern 3.0.31+ (Oct 10 2012). It's been an ongoing issue. Not sure how someone can say "It's hardware related" when stock amazon rom doesn't have this issue. I've been able to recreate it almost 100% using a torrent client (aTorrent, etc) soon as bandwidth hits about 300kb range, the wifi turns to an off setting. Seems if you don't throttle the connection somewhat, the system drops the network layer completely as a out of control app?
I'm going to try a wipe/update and see what happens. It's very annoying trying to get sypebeta installed when its downloader just goes full balls to the wall and dumps at nearly 90% every time

Intermittent WiFi Stability on AOSP

Hey everyone, just came over here from the HTC One X ( AT&T ) forums, smashed the screen on it and used an upgrade to get an AT&T SGS3, loving it so far. Had it rooted and custom recovery, and was on a custom ROM not even an hour after getting home. Anyway, onto the main part of this post.
I tried CM10 ( the 11/01 and 11/02 nightlies), both of the AOKP, and LiquidSmooth, and on all of them, my WiFi stability is not there. It seems to disconnect at random, if connect at all, and when i walk out of range of the router, and then come back, it will not automatically reconnect until i go into airplane mode. Trying to turn WiFi itself off and back on does not work - it won't turn off/back on, it sticks at what it was at.
TouchWiz ROMs, everything works just fine. I'm pretty sure it was working on MIUI as well, but i didnt have MIUI on there long enough to properly test it.
I am using the UCLH9 radio, since AFTER searching the forums pretty in-depth, i found that all radios prior to UCLH9 had wifi driver issues. Flashing this new radio did NOT fix the issue.
I have tried both stock CM10 kernel AND Ktoonsez's kernel (which is pretty freakin awesome, btw! :good: ) and still have WiFi problems.
I have tried flashing ROMs through both TWRP and CWM Recoveries, and have done a full wip of /system /data /cache and /dalvik-cache 3 times each before flashing a ROM.
I'm a pretty competent at flashing ROMs and troubleshooting problems, I am a pretty well-known beta-tester for multiple Sense and AOSP ROMs over at the One X forums, and I have a very good knowledge of how to work ADB and Fastboot. I've been around XDA for a little while, and I know the way of things around here. (don't want you guys thinking im just another a$$hole that threw a post up the second a problem occurred without doing some research first!)
If anyone has ANY ideas as to what may be causing the wifi drivers to crash, PLEASE fill me in.
I've tried all the same things you have and have had no success. The best wifi stability I got was the AOKP_d2att milestone1 w/ lean kernel combination, but wifi would stay connected for 3-5 minutes as opposed to 30 seconds.
I briefly tried CM9, but that still had wifi issues. I might try a few other ICS roms
I came across these threads that documented the problem across other phones:
code.google.com/p/android/issues/detail?id=34942
code.google.com/p/android/issues/detail?id=36993
I've decided that I'm stuck with ICS until the official JB comes out.

Well, I flashed Intergalactic, which is a modded Stock ICS TW ROM based on the AT&T firmware. Shortly after, I reinstalled TWRP recovery and flashed task's AOKP with ktoonsez's kernel, and WiFi works!
This is similar to an issue we had several weeks back with CM10 based ROMs on the HTC One X, you couldn't get LTE unless you flashed a ROM based on Android 4.0.3, it was something with CM10 obviously, because it was fixed in one of the October nightlies iirc.
Try flashing intergalactic and then task and ktoonsez aokp and see if your WiFi is working and let me know

Nope, no luck this way either.
Wifi under Intergalactic works fine.
TWRP flash AOKP milestone 1 alone, with the ktoonsez kernel, or with lean kernal and my wifi still hangs after ~1 minute of inactivity. The phone grinds to a halt. If you can get to the settings, it says that I am connected to my router, but shows no signal bars. If you can then turn wifi off, the phone un-freezes, and (except for no wifi access), the phone is back to normal. If you now turn wifi back on, it stays up for another minute or two and goes down again.
I'm open to any other suggestions.
Thanks though

i am using task and ktoonsez rom....when i first installed it, i noticed wifi dropping, it was annoying.
kinda dont happen anymore. The only 2 things i can think of that might have helped me is; i flashed a new modem i747MVLLE8(I'm with rogers), and under Wi-fi(menu/advanced), i unchecked poor connections.
also my router is 2.4ghz and 5ghz band, but i am connected to the 2.4ghz band.
hope it helps somehow.
I had horrible dropouts and speed with my last WiFi router. I forget the name/model but it was a new model (released this year) that had great reviews.
I went back to my old router and all my wifi problems disappeared.
I do get dropouts once in awhile still. But I haven't done a clean ROM install in awhile.

Telnav problems, won't start

My s3 is rooted, and I'm currently running the people's Rom. Since I loaded the this particular Rom, I haven't been able to get telnav to work. I tried clearing data, deleting and reinstalling from Sprint zone, I even read somewhere that getting rid of Google voice might solve the problem, so l did that and still no joy. It starts up and then the screen goes black and white down, no fc notice. Anybody have a fix for this? It worked fine on jelly bomb Rom and freegs3. I'm beginning to think it's something with the Rom.

[SOLVED] WiFi Can't Obtain IP Address on AOKP

Hello, I've been having a problem with wifi on all new 4.2 roms over the last week or so. For an unknown reason, I can connect with phone data but attempts to get on wifi have been mostly unsuccessful. WiFi just says "obtaining IP address" but eventually times out and starts authenticating again. I have tried wiping everything with 3 different roms and now I'm on Tasks AOKP rom (12/23 with stock kernel) and having the same problem. I've tried all available Canadian modems with the same results (data is best for me on LLH1 though). If I switch back to CM10 (12/16) my wifi works perfectly.
I can get wifi if I mash the on off a few times as it usually causes a force reboot and when it boots I get wifi about 50% of the time. Attempts to modify router settings and reboot my hardware have been futile.
Anyway, I'm hoping one of you is interested enough to peruse the log I saved using "wlan" as a filter. I don't know if that's the best filter but it seemed to show the gist of it. Thank you in advance!

I'm having the same issue task aokp 12/23. Also, if I try to toggle the wifi in the settings screen, it reboots the phone.
However you might try to do this. This morning, I flashed the 12/23 kernal found in task's op. I can toggle wifi on/off now without issue. But i'm not anywhere near wifi to check if it connects.
I found WiFi at target and I'm posting from it. It connected right away.
So, flashing the kernel alone after flashing the ROM, fixed my problem
If you were having the same problem as me, I have to wonder if disconnecting and attempting to reconnect will work.
I downloaded tasks 12/23 underwear kernel, booted to recovery, wiped cache/davlik, flashed only kernel, wiped cache/davlik and rebooted. Tried toggling wifi a dozen times, phone crashed, rebooted, still can't get IP. I imagine that if I play with it long enough I'll get wifi back temporarily, but I use wifi more than data so I'd like it to work better if it can.

Back at home, I can't connect to wifi.
Edit. randomly tried it again, and it connected instantly.
Yeah. I've spent a lot of time troubleshooting router settings (channels, signal type etc) and have thought on several occasions that I had fixed it, but shortly after found that it was a one time connect. I have a spare router in storage that I'm going to try, soon, and that should help me decide if it's a router problem or a JB issue.

Well, no need to play with the router I have managed to obtain flawless wifi, but not on Tasks rom. The 12/27 illusion rom works great, but I can't get mobile data working on it. I switched back to tasks with hope that a future update sets the wifi straight.

I tried the official CM10.1 12/28 nightly this morning and quickly discovered that wifi was working great. I was able to turn it on/off multiple times and reboot without issue. I flashed a different Canadian modem and reflashed tasks AOKP rom (no kernel, no gapps) and wifi was broken again. That logcat makes me think it's something to do with how the rom is handling DHCP requests, but I'm a noob and hardly know anything about any of this stuff.
A nan restore to my AOKP rom got all my stuff back, but it's takes me a solid 30 minutes to get wifi connected.

I updated to tasks AOKP 1/1/13 and my wifi is working perfectly! I considered switching back to 12/12/23 to see if it was the build, but who cares?!
This issue is resolved.

[Q] Data and syncing turn off when screen is off.

After running on a stock ROM(but rooted /w TWRP), I decided that I wanted to install a custom ROM so that I could tether if needed. Well, big mistake. I wiped stock and accidentally wiped my stock backup when going to flash a custom ROM and so far I've tried XenonHD, Jedi X19, IllusionROM, and now I'm on a Stock-Tweaked. So far, every single ROM has caused massive delays in receiving SMS messages and syncs from stuff like gmail.
Data is definitely working, and i've tried both the epc.tmobile.com and fast.tmobile.com APNs but my phone keeps hanging when it trys to send some texts and, if I have texts "waiting" to be delivered to my phone, I only receive them once I turn on my phone screen or only if the screen is on. So what the hell is going on here?
I am not installing anything on the ROMs aside from what's coming with them. The issue presents itself immediately after I boot for the first time and set up gmail.
It seems that if I go to 4G/3G/2G mode only the issue doesn't persist. Or at least not as much. But then I can't use LTE! =/
I've tried multiple ROMs that were TW and multiple that were simply AOSP. So 4.1.2, and 4.3 roms. I even accidentally flashed a 4.2.2 AOKP ROM.(for the Note 2, of course). I am not back to the stock Odin recovery with a root injected stock image but i'm still suffering from the same problem =/. This really sucks. Is there a way to completely wipe EVERY trace of an older Android install off of the phone?
I haven't tried the total stock bare bones one yet because the mirror is so slow, it's currently at 641 / 895 MB downloading and has about an hour left. It's the 4.1.2 June release.
I'm attaching a logcat to this post as well, from when I had the screen on, locked it, turned the screen on, and unlocked the phone.
I just realized the logcat is about 58k lines long, so I'd start from the bottom and go up since that was the most recent phone activity of when I actually went through the motion described earlier.
Let me know what happens when you try the stock sw.

I had this problem is well. I had to call at T Mobile I told him I was getting long delays in my text messaging, yes I know you're not getting delays it's only happen to you when your phone is in sleep mode. I told him I already did all the normal stuff to correct the problem. they reset their network connection. That fixed it for me. Hopefully your problem is that simple.
