Constant wifi disconnects with usb adapter on windows 8.1

[MetoD]

I am running Windows 8.1 using a Netgear WNA3100 N300 wireless usb adapter.

Every time I try downloading a file over 2gb it disconnects before i get to finish. I re-installed/updated the driver, disabled the power management so the pc doesn't turn it off to save power. I have a good signal and the distance from the router is one floor above.

Any ideas as to a solution?

I ended up switching channels in the wifi settings and changing my dns to google's. I can stay connecting for a little over an hour then I get disconnected. Still trying more solutions.

Does anyone know if using a pci card has better connectivity then a usb adapter?
