My wifi adapter randomly disconnects and usually right after that my keyboard does as well. The only way to get my connection back besides restarting is to stick it into another usb port but then I'm left constantly switching port to port until I run out. I have already tried disabling the power saving mode in the usb root hubs and I've also tried changing the power saving option in control panel. Some one please help me this issue has be plaguing me since I upgraded from windows 7 to windows 8,and onward to 8.1
