Setting up an Cisco Lightweight AP previously configured

by Samuel Mitchell, posted in Wireless

We had a problem at work where we had to change the IP address of the Cisco Wireless controller (WLC) and as a result all the APs were orphans with no way to rejoin the WLC.

In our environment, we did not have the CISCO-WAP-CONTROLLER configured in the DNS server so the APs had no way of getting the new WLC IP address.

I had to connect to each APs via the console port (blue) using a serial cable. When I connected to it, I used the default login of Cisco/Cisco which is factory default configured username and password for any APs that joins an cisco WLC.

When I login and went to the privilege mode using command enable. after you have entered the privilege mode, you can use the following AP commands to manually configure the AP network settings and controller IP address to ensure it rejoins the WLC:

  • AP# capwap ap ip address 192.168.0.5 255.255.255.0
  • AP# capwap ap ip default-gateway 192.168.0.1
  • AP# capwap ap controller ip address 192.168.0.2 255.255.255.0

These commands sets the AP’s IP address manually and the controller ip address that the AP should use to register.
