    There is an internal wireless network that uses WPA2-Enterprise with PEAP. I am unable to connect to the wireless network, unless I manually add the network and tell it not to validate the server certificate.

    No other computers experience this. I believe that the certificate was changed recently and I didn't have problems before that, so I would think that my computer is still using that old certificate and is why it isn't working.

    I tried finding the certificate and removing it, but I don't think I really know how to do that. Any help would be appreciated.

    Have you tried removing the network and then rejoining automatically?

    Yeah tried that; it was unable to connect to the network. Then, I manually added it again, unchecked validate server certificate, and got internet again.

    Falling short of the server that is authenticating your computer, I will defer to the next person.

    This sounds like a corporate network. Why haven't you addressed this with the IT department?

    For you to be able to get around the certificate authentication and get on the wireless network, unfortunately, means who ever set it up didn't do a good job. WPA2-Enterprise uses Radius authentication to validate whether a particular device is authorized to connect to even start to talk on the network. But the authentication doesn't end there. The next part of the authentication process should be a username and password challenge. The encryption key used to secure the wireless connection is based on the username and password entered and is only used after the username and password is authenticated. This is usually done via Active Directory or LDAP.

    It does sound like the certificate has changed. You can try to locate the expired certificate by into IE and into Internet Options. From there click on the Content tab and you'll see a button for Certificates. You'll have to hunt through the various tabs like Personal, Trusted Publishers, etc. From there you can upload or delete certificates.

    Again, this sounds like a corporate network setup and you should really be consulting the IT staff for help as if you need a new certificate, they'll be the ones that will issue you one.

    Well, I am the IT department. The boss wouldn't help, because he always tells me to figure it out for myself. Also, since it doesn't affect other people, then it definitely isn't a concern for him.

    I tried looking for the old one, but can't find it or I was just missing it.

    Thanks for the help though.
