Then go to "authentification" tab and untick the box saying "Enable IEEE802.1x to the availiable network" and that should solve your problem Graham UKRight, Graham's solution worked for me.I had been able to connect previously, but the connection would always indicate that it was validating.You just have to find the common setting between the two devices.When setting up WPA you will see the option for either a radius server (Enterprise, and you see this in the corporate environment) or a place to enter a passphrase (Pre Shared Key, PSK).
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.
Then if your operating system is windowsxp please follow the attachment to have a try.(they sent me a file attachment with the email) If your operating system is vista please refer to

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.
