I have a 5508 with 37 AP's working fine running 220.127.116.11. The GUI is OK and everything is working fine.
There is a bug fix I need in version 18.104.22.168, but when I do the upgrade everything works fine, except I cannot get the GUI to load.
Any suggestions welcome.
Solved! Go to Solution.
Still have the problem.
Tried different browsers, clearing cache, disabling Firewall etc etc.
What port is the GUI on as I get this reported error in the browser
CSCux75436 WLC loses default kernel route when dynamic int is created on 2nd port
This should get you back to your backup image (once you access the GUI you can upgrade again to 8.1)
using serial cable, access the CLI
config boot backup
config wlan disable all
config interface vlan management 0
reset > system > y
hope that will help!
Try different browsers. Some browsers work well and some don't. This is the crazy piece. I use to use Chrome and it broke after either I upgraded to a certain code or upgraded Chrome.

Can you be specific about what the browser issue is?
When dealing with 8.0.X and 8.1.X, I use IE 9 after I upgraded two of my controllers to 22.214.171.124 the browser would break. For 8.2.X, I have to use Chrome or Opera.
Enable the option "Inspect Element" and you'll see the errors.
I've run into this issue with a 2504. I also noted that while the WLC appeared to be functioning and manageable via console, the GUI and telnet/ssh were broken. Did you happen to check if you could telnet/ssh into your box after your upgrade?
I don't have a fix yet but just wondering about how similar our problems are.
Had exactly the same issue while upgrading a 2504 to 8.2.100. Switched back to backup code and all went back to normal.
Anyone opened a SR?
CLI is OK but I did not try telnet/ssh. I switched back to 8.1.131 which was the previous version, and the GUI is OK again. I will wait for the next release.
