Eduroam Wifi Issues

[User 15552]

Is there anything in the kernel log about the failure? e.g. run `sudo journalctl -f` in a terminal window and look for red or yellow messages about brcmf when the connection goes bad.

I can't join my school's WPA2 network because of a driver crash after authentication, but your problem sounds different. I'll try connecting to eduroam next time I'm on campus and see if it behaves the same way.

Thanks for the suggestion. I did run `sudo journalctl -f` and  this is what it told me at the time the wifi dropped.

Also the following error: `Error getting the SSID`

Also just saw another error message that keeps coming up and I am not sure if it is related.
