I'm having serious issues with my Dell XPS 15 in that the wi-fi would drop out every 20 mins or so at home. It has been widely reported that the XPS 15 (L521x) has had wireless problems.
I have googled and reset/flushdns
and also netsh int ip reset
but restart couple of times but nothing seem to be working for me.
Can anybody guide me what exactly do I need to fix this issue? my warrenty is expired.
