[Q] Wifi Issues

I would have posted this in the Sensation Android development area, but I don't have sufficient privileges to do so.
I no longer have WiFi.
I am using the 4.1.2 CM Kang, and I originally had WiFi working with that ROM, but it stopped working about a weeks ago, and I can't get it to come back.
If I watch the Wifi on/off toggle, I can see it blink white for a split second then return to grayed out about once every 5-10 seconds.
I've checked the WiFi settings, and the only thing that looks peculiar is that the region code under Advanced says "Europe," but when I try to change that, it just reverts.
I have tried a factory data reset,re-flash of the ROM, and installing newer versions of the ROM with no luck.
Does anyone have any suggestions?

tried this ?

WiFi will not turn on

I tried to install WiFix Manager, and I followed the directions closely, but WiFi still will not turn on.
The country code always reverts back to Europe in the Advanced WiFi Settings.
I'm on T-Mobile US, running AOKP aokp_pyramid_unofficial_Oct-19-12.zip; a JB ROM; 4.1.2
I previously tried the CM10 Kang for the HTC Sensation, but switched ROMs to make sure that it wasn't issue with the ROM.
To be clear, my problem is not that the WiFi radio never locks to a particular signal, it's that the WiFi radio won't even turn on.
When I go to WiFi settings it just says, "Turning on WiFi...," and never actually turns on.
My best guess was that it had something to do with the WiFi country code, but that's really just a stab in the dark; open to suggestions.
Thanks

Surely, there's someone out there that can help?

In order of easiest and quickest to longest time it will take to do each one...
Install the latest version of the ROM (10/23) overtop of your existing rom (5 minutes)
If that doesn't work...
Do a full wipe and install a fresh copy of the latest version. (15 minutes, with Nandroid backup)
If that doesn't work...
Format your SD card (save all the contents to your computer first) (40 minutes between copying every to the computer and back to the SD card)
NON ROM RELATED OPTION IF YOU ARE S-OFF
Reinstall your firmware as it's possible something got messed up. You will have to boot to recovery after this and wipe cache and dalvik or you will get bootloops. (5 minutes, but a little more involved)
My guess is that the full wipe and fresh install is the most likely to work the first time.

is there a sensation specific guide for this procedure?

Still perplexed
How do I know which kernel and radio combination should work best with my ROM. I switched out to AOKP to see if that was the problem, and I believe I'm using the 3.33 Kernel, but I don't know how to check to make sure it installed correctly.

Had the same problem as you but a full wipe and reflash would bring it back. Seems to be a CM10 problem since it happens with Bruce's and Paranoid roms. Try a Sense rom and see if wifi works.

Is OpenSense considered a "Sense ROM?"

Try that rom, more stable and better performance than all the popular roms.

I had the same problem only option was another room Android_Revolution_HD-Sensation_6.8.0 (this is the rom)

so long, and thanks for all of the fish...
I figured it out.
I bought a Samsung Galaxy S III. WiFi is working again.
Thanks for all of the help!

wifi cm10
I have tried several CM10 roms. It is as you said about the region code. It reverts back to the original and doesnt save it on the settings

Even though editing db file doesn't work. Actually it changes the country code. I guess the ROM changes it during booting. Because while it boots you can see that the wifi is connecting first then goes off. I have tried several roms. DOnno what the problem is. probably JB both on cm10 and aokp

Wifi error

So my wifi doesn't work.
Everytime I try to put it on, it switches off almost immediately . Sometimes I am not even able to switch it on at all. (the switch button becomes grey).
I got this phone from a friend of mine a year ago. The wifi wasn't working either back then (but I believe it had worked at some point in the beginning). When I got the phone it still had the stock rom. Then I flashed some custom roms, mostly CM (gingerbread, ICS). That didn't do any good for my wifi. So I downgraded my hboot and s-offed my phone. Also flashed a new radio, but that didn't help either.
I am slowly beginning to think that it's a hardware issue. But today, ever since a year, my wifi turned on and I was connected for 10 minutes! Then I rebooted my phone to see if it would work again, but unfortunately it didn't.
I read something about flashing a new kernel to fix your wifi, could that do the trick?
Also I read a lot about doing clean rom installs to fix your wifi (so wipe all partitions etc), tried that, didn't work.
Info about my phone:
Android 4.2.2
CyanogenMod 10.1 -20130808 -unofficial-saga
kernel version: 3.0.84-g0263617
radio (baseband version): 20.4801.30.0822U_3822.10.08.04_m
Hboot:
saga put ship s-off RL
hboot 6.98.1002
radio: 3822.10.08.04_m
I hope there are some things I have overlooked, because it would be so great if wifi could be fixed.
Thanks in advance!

flash the latest kernel by flinny, it should resolve the wifi issue,
Clean install is preferred when u change ROMS.

Just to clear things up. Do you mean the andromadus kernel? http://forum.xda-developers.com/showthread.php?t=2097379
edit:
I've flashed the andromadus kernel by kylon. Kernel version 3.0.101. Wifi still isn't working.
I can't find the kernel by flinny. Do you have a link?

Wifi Issue

Hello, recently I got my HOX (AT&T version). Obviously, the first thing I did was rooting it (And yes, I'm pretty sure that I did it correctly, I rooted it, unlocked the bootloader, rooted it again, S-OFF it and updated the HBOOT to 2.14 in order to install CM 11). The first rom I installed was the official CM11 and the wifi issue started, I thought that it might have been a bug because it was a nightly (despite the fact that it was the latest nightly). I tried to fix it by installing another rom (PAC rom), and the issue was still there.
After searching for solutions, I tried everything I could: I did a factory reset (both in the ROM and in the recovery mode), I formatted the internal memory, I installed the latest nightly, the official release, I flashed the boot.img using fastboot, I erased the files in /data/wifi folder. But none of this solutions worked.
Here's exactly what happens: I flash the rom and the gapps, then I reboot the phone. Once it boots, I choose the language and I get the google account screen (The one that asks if you want to use an existing account or if you want to create a new account). Before it allows me to choose anything, it goes to another screen that says "To see available networks, turn your wifi on" for about 2 seconds, then it says "Turning wifi on" and nothing ever happens, no matter how many hours I wait, no matter how many times I reboot the phone, it always says the same thing.
I went back to JellyBean for a while and everything worked fine, now that I saw a thread in which an user posted a CM12 build. I did everything again and flashed the ROM, and I still got the same problem.
Please help.
PS: Sorry if I made a lot of grammar mistakes, English is not my main language.

Have you tried running an RUU?
Transmitted via Bacon

I solved it, I was searching how to update the RUU and I read that some ROMs have mobile data/wifi issues if your Hboot wasn't at least 2.15, and I had 2.14.
Anyways, thanks for the help.

[Q] KitKat ROM WiFi reconnect issue

I have read and searched through numerous threads trying to find a remedy to my WiFi issues. While mine are similar to some, I have some uniqueness. I can flash and set up a ROM and phone successfully. After leaving WiFi range and returning I can neither connect nor access any WiFi settings. While accessing the WiFi settings the phone hangs and then settings crashes. After turning WiFi off and rebooting, everything is fine and I auto-connect to the network after boot.
I have tried a few different KK ROM's: KarbonKat, SlimROM and another whose name escapes me. All provide the same reconnect issue. I have also tried three radios, AT&T 2.20, 3.18, and VODAPHONE 5.06 with no difference in performance. I have successfully flashed Candy5 LP ROM (and all is working fine) but I love the customization of KarbonKat and would like to hang with it. Does anyone have any insight on the problem or any WiFi tweaks that I am missing that could help? I am HBOOT 2.15 and S-Off. Thanks.

CM13 no sim

Hey guys, I just flashed the CM13 nightly from stock 5.0 and now I'm showing no sim card. I saw a couple threads saying that newer twrp builds have issues with flashing radios, so I reverted to twrp 2.8.6 and did a clean flash, with no love. Tried flashing the radio zip, no love. Tried flashing the 3 most recent radios through fastboot, no love.
Any assistance would be greatly appreciated

Are you flashing both the bootloader and radio? If this doesn't work, I suggest flashing the latest stock MM to make sure the phone is working, then flash CM13.

Good call, trying it now

okay, flashed to stock 6.0.1, worked like a champ, flashed back to cm, now it connects to the network, but drops to no service after a second or two. Progress! Now that I know that you have to flash bootloader and radio, i'll try some different combos and see if i can get something to work. If nothing else, i can always go back to stock MM
Thanks!

Have you tried CM13 with a custom kernel? This may solve the issue.

You need to do alot of reading, no insult intended. Don't run b4 you can walk. If you didn't know to flash the radio and bootloader you need to learn alot. Luckily it's a bullet proof phone. Nightlies are not stable and not for daily drivers. They are works in progress and buggy as a result. Not for noobies, IMHO

The OP did flash different radios. It is not always necessary to flash a modem and bootloader to have a working phone.
