My LG 8.3 has been working fine for over a year but recently it's started losing wifi every few minutes. I have good signal level, I've used a sugnal analyser to check for channel interference and that's fine, I've tried it on other wifi networks, but same problem. Have to go into settings, select the wifi network and connect, fine for a minute or so then drops out again. Also uninstalled recent apps in case something was interupting the wifi. At a total loss for what to try next, the pad is virtually unuseable. I'm running Android 4.4.2. Anyone have any ideas??
