Wifi not connecting after updating roms - EVO 4G Q&A, Help & Troubleshooting

I have a problem with my wifi not connecting after I've updated to a new version of a ROM.
For instance, with Myn's warm, wifi and everything worked perfect, however after updating to the second version, wifi will locate but not connect to and hold the signal.
The same goes for MIUI.
I always do a full wipe and if I flash back to the first versions of these roms the wifi works fine.
Is there something that I am missing?

[Q] AOSP rom issues!!!

I have flashed two different AOSP roms (evo deck, and savage-mod). Everytime I get them up and running I am having the same issues with them. My 4G has trouble toggling on and off. It will boot up on, but as soon as I turn it off and turn it back on it gives me an error. Same with the built in hotspot. Also tried using the wireless tether app from the market and when I start tethering it just sits there. Once I hit the back button and start again it says "tethering has started with errors..check log" Everything else seems fine. GPS works, mms, 3g speeds are fast. I just don't understand. I have ran AOSP roms before with no issues. I'm flashing using CWM and doing three wipes each of factory data, cache, and dalvik. Then running a superwipe before flashing rom. Any help????

Y dont you just use the built in hotspot aosp roms come with?
I have tried that. It says "error" as soon as I try to activate it. It's like it intially works sometimes right after reboot, but then breaks after I turn it off and try to activate it again. And I prefer the app because you can tether 4g from it
Edit: So I flashed the newest tiamat kernal 4.08 and it seems to have helped with the 4g, and the built in hotspot. The 4g icon does not turn green, but it is in the status bar and speed test show its on. The only thing not working is the tethering app.

[Q] TMOUS ROM 3G data problem..

Hey Guys..
I had the hard work done, got s-off and had clockwork recovery on, but was having problems with wi fi/data knocking itself off at any times. Turns out it was a bug with the rom, so i decided to change to another..
and made a mess. Eventually i lost cwm recovery, was back to the chinese one and flashed TMOUS and eventually got it going. It looks and works great, except..
no 3g data. Wifi is perfect, gps is fine i think(latitude working) but no 3g connection, even though it says in settings that network operator is identified and 3g data is enabled also.
I reflashed a few times, same as. do i need to reflash a new radio?

[Q] wifi not working after updating

I updated my rooted G3 running stock rom using the LG Support Tool today, but the wifi does not seem to work after updating. When I open up the wifi tab, the wifi is switched off, so i switch the wifi on, however, it would not detect any wifi networks at all. The box where it usually lists wifi network still says "turn wi-fi on in the upper right corner to see available devices", but ive already switched wifi on. the wifi was working just fine when it was running kitkat

Do a factory reset. You would probably run into other problems like chrome not knowing where the sd card is when trying to download. I thought it was running perfect but ran into the sd thing, then I noticed my wifi was bugged. All my problems where fixed after a factory reset. Important to note that I didnt use the kdz to update instead I used a twrp zip I made. Another note, pretty sure that I dirty flashed from kitkat that last time when I noticed the problems (fashed both ways for testing).

[Q] WiFi stopped working.. Tried everything

I've done a lot of searching around here and couldn't find anything that could get my WiFi working again. A while back I was following a tutorial that would let me edit my network bands, but I could never get it to work.. Shortly after I noticed my WiFi stopped working. I'm not sure if it's a coincidence or not. Anyways, I've tried everything. I've used stock RUU's to flash it back to stock (erasing everything), installed different ROMs, Kernels, etc. I've noticed the WiFi will work shortly after a fresh install but after a bit it just stops. Turning it on will give a WiFi error followed by "settings has stopped working". I've even opened up my phone and made sure the antennas were connected correctly but that didn't do anything. My Bluetooth works just fine though!
I'm s-off and rooted
Helped one of my friend - installed latest firmware update, but he has phone without root and locked bootloader + s
-on
Where can I find the firmware update?
Did you try using a different SSID ?
Or did you verify the RUU flashes clean ?
Maybe your WiFi Chip is broken
