Okay I have a nexus 7 (an android tablet). For the first 3 months it works wonderfully, but recently it has started disconnecting from the WiFi each night at about 12:15 a.m. It won't load any apps after. The WiFi signal is still strong, but the icon turns from blue to gray. I checked with my brother(just in case my dad set a timer) but he didn't notice anything so it works in the rest of the house. Does this happen to anyone else?
