it quits working when I----
One problematic fix i had to do was an older gentleman kept bringing in his laptop complaining that his wi-fi quit working. Turn on laptop, connect to my wi-fi, worked fine every time he brought the laptop in.
Shortly before I retired he had the laptop back in. My wi-fi isn't working, and hasn't worked properly since the last time i saw you.
Again, connected to the wi-fi I used and it worked fine (I had learned to just leave the connection in the list).
Showed him it worked fine and again asked if he had any problems with his other wireless devices.
He said he never had any problems with his phone or tablet, but every time he plugged in the Ethernet cord, his wi-fi quit working on his laptop.
Cue Loony Tunes music and a Yosemite Sam angry face.
