• config network web-auth https-redirect disable
• config network web-auth secureweb disable

Additionally, we need to prevent users from trying to log in to the ME GUI via RADIUS. Provided you have only added the two RADIUS servers above and don't have any others configured, run the following commands:

• config radius auth management 1 disable
• config radius auth management 2 disable

After applying the commands above you will need to reboot the controller. Type the below commands:

• save config
• reset system

The ME AP will now reboot and be ready for use.

NOTE: You need to add all the AP Base MACs to the portal. To see these, type show ap join stats summary all from the SSH or command line.

! You must also install a valid SSL certificate on your controller/AP, in order to avoid authentication issues !
