I recently bought a new Linksys wireless router and after setting it up with basic WEP security, I tried to logon from my laptop and was successful! So then I tried to connect from my desktop computer that has a wireless USB adapter attached to it and I ended up getting this error message: Fabulous! I checked my settings on the wireless router to make sure I didn’t accidentally setup certificate security, but found no such thing.
Also, since I was able to connect from my laptop with no problem, it led me to believe it was something wrong with my desktop.

If a self-signed certificate (or any certificate from an untrusted CA) is in use, most clients will reject the connection since they cannot validate the server's identity.
