I'm working on my sisters computer that she got for Christmas a few months ago. its a brand new DELL~ INSPIRON 15. but there is something wrong with the wifi, I can get it connected but it randomly disconnects for no reason and its getting really annoying. if anyone knows how to fix it please tell me ok.
you can message me on facebook
my name is Austin Green
thanks

Driver issues, placement of the router in comparison to the pc, is the router signal going through several walls? Power settings have adapter not running at maximum performance. good luck
