WiFi will not stay on - Atrix 4G Q&A, Help & Troubleshooting

Atrix 4G 4.5.91 rooted
Nothing else done to it.
I have been using my WiFi, along with the AT&T Smart Wi-Fi app for a couple weeks with no problem at all. I have not installed anything new or changed anything at all.
For some reason today, my WiFi will not stay on. I turn it on, it brings up the "Wifi networks found" and then Wifi just shuts off. I can no longer connect to WiFi because the service itself just shuts off.
And when I try using the AT&T Smart Wi-Fi it won't connect at all. Just hangs for a while and then says it cannot connect (because WiFi shuts off.)
Please help! I am now the victim of the AT&T "unlimited" data plan BS where they slow me down if I use too much data, so I have to use WiFi.
About the only thing I can think of that has happened in the last day different than normal is that I had the juice run out of a battery. But WiFi worked fine after putting in a new battery. I have no idea why it just all of the sudden will not stay on.

Phone doesn't attempt to reconnect to network

Hi guys, I have enjoyed my HD2 for a half year now, but after a recent trip abroad, during which I pulled out my sim card, my phone now does not try to reconnect to the tmobile network after losing a signal.
For example, I do not receive a signal at my school, however, when I leave school in the afternoon, my phone still does not receive a signal. I have to manually go into phone settings in the comm manager and "find network" to be able to connect. Does anyone know how to fix this? Because this is really annoying having to do this everyday after school...
the phone stops searching after so long. (Cant remember how long, an hour, maybe)
HTC say this is to prevent the phone spending all day searching for a cell tower, which it does at full power, so your battery would die rather quickly.
Rather than manually searching for a signal, you should be able to switch to airplane mode then back to normal again.
well, it used to work fine before I left the country, and turning the antenna on/off does not solve the problem

[Q] Phone powers off after a few minutes of tethering

On latest archidroid. I'm heavy travelling right now and really require hotspot.
After about ten minutes of WiFi hotspot my phone won't turn on. Tether stops working. Whether os is just frozen I can't tell. No backlight. But I do need to hold power for a long time to get it going. Feels like I have to do it twice, not sure.
Any ideas? Would really appreciate a solution.

[Q] Wifi speed suddenly turn extremely low

I am currently using Nexus5 with android 6.0.1. I have used it for 3 years, everything works fine.
However, starting from yesterday, whenever I try to connect my N5 to my router's wifi, the wifi speed gone very low (<1KB) and this also slow down the internet speed of all devices that connected to the router. All things back to normal after disconnecting the wifi.
What is the cause of the problem? It is strange because the phone looks good and it happens suddenly. I tried to reset/reboot both the phone and the router several times but nothing helps. Please help!

Having The same issue with WIFI

WiFi connection dropping.

Hello
I had this V30+ H930G for awhile and it's been about 10 days that my WiFi keeps dropping when I connect it and if I try to reconnect it quickly after it drops (by clicking Connect) nothing happens so I have to either wait a few seconds or disable and enable wifi to get a retry at connecting which I still have a high chance of getting DCed again from WiFi.
Here is what I tried so far:
4 Different WiFi routers one of them were another cellphone.
Network Reset
turn on and off battery saving
Updating/repair phone through LG Bridge.
Reset/Erase everything.
sometimes my WiFi stays on for hours but sometimes it just drops every 5 seconds. with full 5 bars
even if the WiFi is open and not password protected it drops.
so does it sound like hardware problem? I didn't try to downgrade to previous versions. I don't wanna repair this phone if possible, but I'm still wondering if this is a hardware problem or just software?
