Using my 'new' Gateway PC I have tried to upgrade 8.0 to 8.1. Each time (3x) the PC goes thru the entire upgrade (download, gathering info, installing) for a period of a few hours. Then it tried to perform a restart and THEN tells me it can't complete. I think I traced it to an incompatibility with my wireless dongle driver software for the by ASUS, a USB-N13 (N300 Adaptor) When I try the web site for this device to get the latest driver, I see only compatibility with Windows XP (the latest MS OS!) I purchased this dongle in Nov 2013 and don't see why MicroCenter would sell me something so outdated. Is there a fix/patch/download yhat gets me out of this morass?
