So I'm going to try to explain exactly what's happening, but I might leave out a few important details because I don't realize they're important.
At my university here in Denmark, I connected to the campus wireless network for the first time last week, and everything worked fine. I'm on a Macbook, and I connected by going Network Preferences ---> Airport ---> Advanced ---> 802.1X and there I put it the appropriate network and login info. Everything worked.
Today, however, the second time I've tried to use it, I'm unable to connect to the Internet. On the Network Preferences screen, it says Airport has a "self-assigned IP address" and cannot get online. It doesn't appear to be authorizing my login to the network. I asked our campus IT specialists this morning for help, and they couldn't figure it out.
When I first signed up last week, I had to click to allow a certificate to be stored on my computer; the IT guys seemed to think finding this certificate and deleting it would help. But we couldn't find it. I deleted all the certificates stored in my Keychain, and yet it just wouldn't prompt me to allow the certificate over again. Any other places to look? Or any other possible explanations for this problem?
Apologies if I'm leaving out any crucial info, please let me know if I need to describe anything else.
EDIT: Also, I have no idea why the flag above my post says I am in Tibet. Tibet?!
We'll be back right after order has been restored here in the Omni Center.
