I was running hellfire but then my tablet "froze" so i forced it to shut down and power back on. It kept freezing. So then I installed cm9 energy and it didn't freeze but wifi wouldn't work. It would say "turning wi-fi on" forever. I then advance restored my kindle 6.2.5 stock backup in its entirety (with multiple wipings between each rom btw) and it was glitchy AND wifi was still failing. Although it would say that it was on, it clearly wasn't working. I then took the 6.3 update and flashed that. It acts like it works, except that it says that no wifi networks are available. (fyi I have 3 routers: 1 for guests (802.11b), 1 for family (802.11g) and 1 for me (802.11n 2.4/5ghz)
Since I "think" i'm fully back to stock, including the kernel: I don't get what's wrong.

Problem:
1) Bill (TMobile) is past due. for about 3 weeks ive been using wifi only in my house to stay connected, working just fine.
2) for about 3 months, ive been USB tethering to my desktop since it doesnt have a wireless card. now it takes my home wifi signal to the phone, thru usb, to the computer. all drivers are full up-to-date.
3) two nights ago i installed the new 2.3 Gingerbread update from LG's site, went without a hitch.
4) ever since then, my data has been freezing at downloads, browser instantly jumps to page not available, "Data Error, Retry" popup, only when im NOT tethering though. normally id blame the update, but there are plentyyyy of people without this problem.
5) yes, you heard right. when my phone is plugged in usb, it wont connect, but when i enable usb tether, the data to the phone works. its almost as if its my COMPUTER giving signal to the PHONE. this is ridiculous. when i unplug, the data continues to work for about 1 minute, then nothing.
im completely stock 2.3 with not a single new app downloaded. so i factory reset and wiped everything, loaded back in as if it was out-of-the-box, same results.
ive tried switching my WiFi off policy to never go to data (shouldnt matter, i did this for weeks without changing that, so i set it back to the standard option) i also know in 2.3 if your screen goes off it switches to data, so i set my screen to stay awake while plugged in.
needless to say... HELP.
I posted a similar thread in the forums for the T989, but didn't get a good response, so I figured I'd try here.
Basically, my wifi stopped working for some reason a while ago. I got it early in January, and the wifi was working initially, but eventually stopped for some reason. I tried rooting it and upgrading it to ICS, and the wifi began to work sometimes, but it was hard to tell what I could do to trigger it working. I think it had something to do with toggling various power saving settings.
Anyway, I've tried basically everything to get the wifi working. I've tried dialing those test codes, like *#*#526*#*#, and those didn't work. I've tried flashing various custom and stock roms, being rooted and unrooted, flashing kernels, flashing the radio, using Wi-Fi fixing apps, etc, and I haven't been able to fix it.
Right now I'm on AOKP Jelly Bean 4.1.2, and the Wi-Fi works intermittently at best. Last night it was being incredibly cooperative, but for some reason this morning it quit on me again, and won't work. Currently, the switch to turn Wi-Fi on is greyed out, and I can't move it, but the screen says "Turning Wi-Fi on...". I'm seriously at my wits end, and have no idea what to do. Can anyone offer me any help here?
I've had the 4.4.2 OTA about 2-3 weeks now, and for the most part its worked fine but as things go on I am noticing it starting to go a bit buggy. I have had issues with my Wifi, like this morning turned the phone on and it would not connect to my wifi, sure it saw it and it had full strenght but it would not connect to it, I went in manually and selected it nope nothing, I forgot network and connected again, nope nothing, restarted the phone nope, after 5 restarts it connected. I've also had issues with wifi connecting when coming out of airplane mode, everything else turns on but I have to mess around with wifi to get it going again.
Also had issues with apps crashing randomly, also had periods of sluggishness for no apparent reasons.
Anyone any ideas?
About the Wifi, try the Wi-Fi fix in this forum, maybe that'll help. For me stock is going absolutely fine. I was on OmniROM, but the updates start becoming a little buggy for me, so I switched back to Stock.
I have an S7 edge (SM-G935F) that currently runs the Superman rom. It has a strange issue where suddenly, out of nowhere, wifi stops responding. It has done this before, but then it was on stock rom. It was actually one of the reasons I reflashed it. After flashing, everything was fine for 2-3 months and then it started acting up again.
It's so bad that I now mostly run it on 4G (luckily I have a 35GB plan) because it can take upto a full minute to get it to respond on wifi after it's been sleeping.
As far as I can tell, the problem manifests itself like this:
* Phone has been unused for a while, wifi is on, wifi is connected to a network (problem is not network specific)
* I try to open any app that uses data, no response. If I just keep hammering retry/refresh/update etc it starts responding after anywhere between 20-60 seconds.
* During the non-responsive period the wifi-icon sometimes gets the little exclamation mark, but not always.
* After a period with wifi off it sometimes uses 20+ seconds to refresh and connect to a known hotspot.
I can probably fix it again by reflashing another rom, but I'm afraid the problems will be back in another few months.
Any suggestions on what I can try (besides returning it, I'll do it if I have to, but I'd rather not). Are there any wifi logs I can check after the problem appears next time. (I know how to use a terminal)

Install the stock rom. It was your faulty custom ROM if all get back to normal.
Sure, I can do that. But you did see that the problem existed before I installed the custom rom right?
The original manifestation of the problem was the reason I flashed another rom in the first place.
Hi, im having this problem for a while, and some other phones are showing this problem also (here)
in summary, phone connect to WiFi, works great, turn screen off, put phone down, and after a while, phone is now unreachable. can't connect to it if i have a ftp server on it for example, can't connect on whatsapp on the PC cause it need the phone connected to work, messages won't arrive, or arrive after 15 minutes of delay.
if i pick up the phone, unlock, WiFi does not work, it keep showing only the "up" arrow and no "download" arrow. can't connect to internet, can't connect to local PC (VNC for example) nothing works. after 30 seconds or so, it comes back, and internet works. sometimes it does not. disabling WiFi and enabling again, everything works fine. if put to sleep, everything start again.
the weird thing is, usually after update to a new version of MIUI (for example, the last 12.0.5.0 a few weeks ago) the problem goes away for a few days. always works great, every time, no problems. a few days later, the problem appears again.
tried everything i could find, no option helped, tried even disabling magisk/xposed, etc, to make sure no "mod" was causing it, nothing.
my only options now are formatting and starting from 0 or try another ROM, like LineageOS, but i'm trying to avoid cause i have tons of customized apps, bunch of banking apps, and everything works fine, except for this one problem.
any help appreciated!
PS: during the whole time, the wifi do not get "disconnected", it remains connected but not working. also tried different routers, no change. using only 2.4ghz.
I installed Lineage OS, the problem didn't show up anymore.
installed all the apps previously installed, everything still working fine for over a week.
I guess was just software related...
