LG G2 WiFi Issues

Hello,

So suddenly my LG G2's WiFi stopped working. It detects networks and refuses to connect. It does connect once in a while, but says "Internet unavailable"
I've tried multiple WiFi Networks. I've reflashed Lollipop, no luck. I flashed the stock KitKat and still no luck.

Would anyone be able to assist me? :confused:

Thanks in advance,
