This error is why i could never run Windows 8.1 on my machine and it seems to of transferred over to windows 10 too.

I've had this issue with my old netgear wireless adapter and this one. It happens around 2-5 times an hour, i looked it up and I've tried many fixes some of which include: Setting power settings to Max Performance.
