I have a Lenovo ThinkPad Egde E520 (1143) and I have trouble using my Wireless adapter under Win8 64-Bit. On Ubuntu 12.04. 64-bit I have no trouble. The problem is that I almost always only get a limited concectivity to my network and sporadically I get a full connection. Also my computer presents problems while installing the Bluetooth driver.
Could it be that WIN8 64-bit and my wireless-adapter are not compatible?

if you need it). I see on the Lenovo Page that they have W8x64 available for the Intel card. Though the w7 driver should work.. Have you tried plugging in Ethernet and doing a Windows update to see if Windows does it automagically?
