Cisco Wireless Controller - all Wireless clients getting duplicate IP error.
Posted on 2012-04-13
I have a Cisco 2504 Wireless Controller with one lightweight AP. The AP, WLC and wireless clients are all on the same subnet.
Every single wireless client gets a message that it has a duplicate IP address, even thought they don't. I even went as far as to assign a wireless client a static IP address that's not part of our DHPC leases and it gets a duplicate IP address error.
I'm a novice when it comes to these and the person we paid to set it up doesn't have a clue.
