Network problem validating identity
I'm trying to set it up using Windows as opposed to the proprietary Rosewill software -- the Rosewill software is a little over my head.
It can find the network fine, but when I try to connect, I don't get the password prompt -- it moves straight to "validating identity," scans, and then says "Windows was not able to find a certificate to log you on to the wireless network Foo." The maddening thing is that the card was working fine a week ago, in the same box, using the same OS.
In order to connect to eduroam network in future, simply bring up Wireless Network Connection window by double-clicking its icon in the tray bar , select eduroam network and click on Connect.
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).
Please refer to the documentation of your vendor's card in order to turn it off as this may interfere with the procedure here documented.
I cannot get WPA2 enterprise to work on my network. Windows Domain, using IAS and its own CA Linksys WAP200 Access Point I setup the AP to use WPA2-Enterprise Mixed using RADIUS I setup and registered IAS on the domain controller.
I added the AP as a client with and have tried using both RADIUS Standard and Cisco as the RADIUS type.
The client settings on the laptop match the IAS settings and the certificate is definately installed.In a few simple steps you can bypass Windows Validation, and the resulting "Limited or No Connectivity" issue on an encrypted connection.In the next window click on the "Authentication" tab, Make sure "Enable IEEE 802.1x...." checkbox is UN-Checked, the rest of this window should be greyed out.I then tried installing the supplied Sitecom N adapter, after some problems the network appears but I can't connect, I am told "Windows was unable to find a certificate to log you onto the network" I read several threads that led me to uncheck "Enable IEEE 802.1x authentication for this network" and I actually managed to enter the WPA2 code but this just leads to the message "This connection has limited or no connectivity" and "validating identity". In any event I am finding that after rebooting the WPA2 code is no longer there and it has reverted back to Open WEP.
