Strange Decrypt Errors on WLC

Hello,

I'm using a WLC 2100 series, and I have an issue where my wireless network will work perfectly for a few days, then all of a sudden I will see hundreds of "Decrypt errors occured for client <Mac Address> using WEP key on interface of AP <Mac Address>." At this point the clients associate with the controller, but they do not receive a DHCP address. Has anyone run into something like this before? If anyone can offer any insight it would be greatly appreciated as I'm not sure what to try next.

Thanks,

Steve

Try to upgrade the firmware on the devices. This is usually due to incompatibility isses with the devices. Are you using WEP or another authentication method?
