wlc 2100 error

hugh.lancaster — Sun, 04 Jul 2021 01:59:09 GMT

Just purchased and installed a Cisco WLC 2100. I am getting the following message on the controller:Decrypt errors occurred for client 00:18:de:82:eb:57 using WPA2 key on 802.11b/g

The client is connecting but I am not getting a dhcp address.

Hugh,

What code verson is running on the WLC? If you are running any 6.0 other than 6.0 199.0, then you need to upgrade as there are some nasty bugs in the other 6.0s. One of which allows a client to associate, but then not be able to get an IP and all you see on the controller is decrypt messages. There is a software advisory for these issues:

Thanks,
