For the life of me, I can't figure out how to get the mini to connect to my 5ghz network while running Windows 7 (x32). If I boot up to Lion, which has all the latest updates, I can connect to the 5ghz network, so this must either be a driver issue or a settings problem within the Windows 7 environment. It appears that the Mac Mini uses this Broadcom adapter (BCM943224PCIEBT) I have the latest version of Boot Camp (v3.3) installed, but the WiFi driver contained here is one from 2009. So I upgraded the WiFi driver to 184.108.40.206 for BCM43xx to no avail. The adapter still won't log into the 5ghz network. To be clear, I can see the network broadcast, but get a message "unable to connect." I had the same problem in Lion before installing the latest updates, so something in the latest updates fixes this problem on Lion but Apple is yet to roll out this fix in the Boot Camp drivers. - Router: WNDR4500 (N900) - Network has all encryption disabled Huge thanks to anyone that can solve this riddle.
