Whenever i plug in my ethernet cable my keyboard stops working (g19 logitech). I can see the lights on the keyboard and screen but it stops functioning and i have to unplug/replug usb for it to be back to normal.
Any ideas how to fix this.
p.s I am aware i have other issues as well but please could you respond to this one if you can.
thnx
