I've just built a system and did a clean install of Windows 7 Home Premium 64-bit, and I can't get the wireless card to connect to anything (NEXXT 122NXT12). I had first installed 32-bit and it worked fine with Windows default drivers, but now even with 64-bit drivers it won't work, I am however getting a message about the drivers not being digitally signed, can this prevent the card from working? I've tried disabling driver signing using elevated command prompt (http://www.howinthetech.com/disabling-digital-driver-signing-in-windows-7/) and Driver Signature Enforcement Overrider (http://www.raymond.cc/blog/archives/2009/08/24/loading-unsigned-drivers-in-windows-7-and-vista-64-bit-x64/), neither seem to work. Can anyone help me figure this out? Or even better, direct me to drivers that would work?
