Hi Khaleefa,

This is a pretty common problem that is usually associated with one of 2 things;

1. The time setting on the WLC and the PC running the upgrade tool (must be in sync).

2. A problem with the SSC (Self Signed Certificate).

Have a look at these great threads from last year that provide answers to both problems.



Here are some excellent docs;

Lightweight AP (LAP) Registration to a Wireless LAN Controller (WLC)


Hope this helps!
