Connection Issues on WPA2 Enterprise WIFI

[CyberWolf25]

I have been having strange connection issues on my university's WPA2 Enterprise WIFI that uses PEAP authentication with MSCHAPv2. I can connect to the network with my username and password and then It works for a little bit, but after 1 to 2 minutes it stops working. The network shows as still connected but no websites will load and no data can be sent or received. In this state web pages will simply try to load forever. Home WIFI and Ethernet work fine. The only way I have found to fix it is to turn WIFI off an back on again from settings but this is not practical to do every 1 to 2 minutes. There appears to be no real consistency in the time it takes before connections stop working but it usually happens fairly quickly after connecting.

I am using 64bit Linux Mint 20.3 on a Lenovo laptop with an Intel Core i5-1035G1.

Have you contacted the IT department at the university? I would.

Have you contacted the IT department at the university? I would.

Unfortunately, they just tell me that they only provide limited help for Linux devices so they can put their resources towards the majority of students who use windows or mac. The help they provided boiled down to make sure your password is correct and WiFi is enabled. They then tell me that they will not provide further support on their end and that I should use Windows to ensure compatibility.

Sorry to hear that.
