Yes and yes. It doesn't work, by not finding any networks to join.
Might sound stupid, but check if the powerswitch (if any) is enabled. Look if you can find any networks using the NetStumbler
application. Preconfigure your wireless network in the Network and Sharing Center
-> Manage wireless networks
and see if you see any traffic in the Wireshark
packet analyzer (also try promiscuous mode).
If all of that doesn't result in anything it looks like the driver isn't compatible... One thing you can try if that's the case is, to connect your PC to the Internet using a Ethernet cable and run Windows Update. Another possibility is to install Windows 7 and if it works using the included drivers or Windows Update drivers, extract these using for example Driver Genius
and use them in Windows Server 2008 R2.
Hope this pushes you into the right direction!
