Just upgrade software on my WLC5508 from 7.0.98.218 to 7.3.112.0 via GUI interface.
The upgrade was successfully,I can login to WLC.The other 2 WLC also upgraded to the same version and works.
The only issue,for Guest Vlan user didt get IP address and web login page.
Then we decide to revert to old image and working normally
Do you have any suggestion how to troubleshoot it?
