wireless network, cannot find certificate

[Red Squirrel]

I have a secondary nic I use to connect to my external network but for whatever reason it wont work anymore. It says it can't find the certificate (what certificate? for what?) so it wont connect. I entered the WPA2 key and it worked fine a day ago now all of a sudden I can't reconnect to it. I tried to delete it and reconnect and reenter the key, still nothing. Anyone ever seen this before?

Your authentication type has been changed somehow. Change your security settings to match the access point, do not rely on automatic. The certificates are used for protected authentication.

My guess is your client is set to WPA-Enterprise and have PEAP, EAP-TLS or some other enterprise authentication selected instead of just straight WPA-PSK.

After messing with it more it ended up working, but I'll know to check that next time.
