Thanks, I think this is the answer! I was having no problems today but noticed that the PC was connected to 5Ghz. Sometimes it connects at 2.4Ghz. When I disabled 5Ghz and forced the PC to use 2.4Ghz the problem came back. So now all I need to do is seperate those services and/or tie the PC to 5Ghz. The PC is a laptop but I never move it from the desktop. I am using a USB mouse and USB keyboard adapter to an old IBM keyboard. > https://sortatechy.com/spot-and-fix-bluetooth-interference-with-wifi/ > > If your PC is using wireless and can use a 5Ghz channel, try moving > your PC wireless to a 5Ghz channel first.
