Ubuntu 16.04 doesn't support PEAP authentication without CA certificate

Question

In our college, we have PEAP authentication system for LAN Authentication. With the new Ubuntu update to 16.04, the PEAP Authentication asks for the password again and again and doesn't connect. It used to work perfectly in Ubuntu 14.04. Any suggestions?

Answer 1

Please use nmcli to add the password.

1. Edit /etc/NetworkManager/system-connections/CONNECTION_NAME:

   [connection]
   id=CONNECTION_NAME
   
   [802-1x]
   password=YOUR_8021X_PASSWORD
   

2. Restart your network

   systemctl restart NetworkManager
   

3. You may need to bring the interface down and up to test the new changes:

   nmcli con down CONNECTION_NAME
   nmcli con up CONNECTION_NAME
