Hi Khalid,

Paste the output of these commands:

sh sysinfo from WLC

sh version from AP

Also paste the complete bootup process from AP console.

also this is the bootup process

[Sandeep Choudhary]

which method are you using to discover WLC ?

Your AP and WLC are in diff subnet/vlan ?

Also paste the output of this command:show auth-list

Product Version.................................. 8.0.121.0

There is a very good reason why Cisco no longer allows people to download this specific firmware.  I strongly recommend to upgrade the firmware first before doing any troubleshooting.

This version can still be downloaded, 8.0.120.0 has been removed.
