LG G3 Wifi Connection Issues
I have the same exact issue. Literally same exact issue. I got mine to work for a little while after setting my WiFi to broadcast B&amp;G only. I really hope someone finds out how to fix this issue soon. Btw I'm running XDAbbeb's ROM and have tried 3 or 4 others.

Edit: People on the G3 reddit are reporting this issue as well. One user said that replacing the battery fixes the issue.
