On a System76 Darter Pro laptop with Ubuntu 18.04, the WiFi at my school suddenly stopped working, but I can still connect to my dorm WiFi.
I recently changed my password and then when I had to reverify my information to sign in it asked for a domain which was odd. I'm able to connect to my dorm wifi still because the password for that wifi hasn't had to be put back in. The wifi will attempt to connect when I press "no CA certificate is required" but it never works.
If it makes any difference I'm attending ASU, we have 2 wifi's that are possible to use; the ASU wifi, and eduroam wifi. They both use PEAP wifi, I am very new to any network connections. I have tried EVERYTHING I could find on google and asked in all geo-stories, went to the tech service center and they didn't know what to do. I tried using the certification that ASU recommended to use and that didn't work. It's getting to the point of affecting my school work so please if you have ANY suggestions please let me know!
