Click on Properties once you select the wireless network that is having problems.
You will need to enter your encryption information here in order to connect to your network.
Select your encryption type from the "Network Authentication" and "Data Encryption" drop downs.
If your network is Encrypted go on to step 6 otherwise Click ok and try to connect to your network again.
In this window make sure you are in the "Association" tab.
I can't figure out why I can't get it up and running now.
There's no WPA2 on the card, just WPA and WPA-PSK: WPA-PSK was the only setting that would let me enter a network key.
If, for any reason, the connection turns to Manual, in order to re-connect, just bring up the available Wireless Network Connection window by double-clicking its icon in the tray bar , select eduroam and click on Connect.
In order to configure the connection back to Automatic, edit the eduroam profile, go to the Connection tab and check Connect when this network is in range: Figure 14: Setting Automatic connection  = If the Wireless Network Connection icon is not present, this may be due to the wireless network manager of your vendor's card taking over from Windows' built-in one (Wireless Zero Configuration).
If the box was checked, then that was why you were getting the “unable to find a certificate to log you on to the network” message because Windows is looking for one, but your wireless router is not setup for certificate security. Once I unchecked that box and tried to reconnect to the wireless network, everything worked fine!
