Many people seem to run in-to this problem, none of the suggested drivers from other various forum posts including this one would install or be recognized by Windows 7 Enterprise SP1 x64.
I found using the Intel Centrino Wireless-N 2230 driver downloaded directly from Intel's site worked (don't confuse it with the Bluetooth driver).
Hope this helps.
