Ok, updating my sister's PC to windows 8.1 it has no drivers for her wireless adaptor. It's a SMCWUSBS-N4 wireless N adapter. It works in in windows 7. Going 5 bars @ 150Mbps with no issues. Here's the website: http://www.smc.com/en-global/products/product/46
If anybody can jimmy rig this or find generic realtek/tp-link drivers for this it would be great.
PS. Already tried doing all the x64 drivers on the page, so don't suggest that.
