Every once in a while, my laptop simply. Stops receiving wi-fi. With or without the Fn-F3 combination to turn it on/off. This is always accompanied by slightly corrupted audio in whatever may be playing, and occasionally a small amount of system lag.
It first seems to drop my home wi-fi, then all the others on my local list vanish all at once. Plugging in an ethernet cable does NOT fix this, it tells me that I have 'No Internet Connection' through that network, despite it being plugged into the router and being a good cable. Other devices have no problem connecting to the router, the problem is with my laptop. Stops seeing any connection whatsoever.
