My customer is using Cisco WLC 4402 running 220.127.116.11 and is reporting that Wireless clients are getting disconnected and reconnected every half hour and when I check for the trapslog I get the following error messages.
Decrypt errors occurred for client 00:19:d2:76:2e:7e using WPA2 key on 802.11b/g interface of AP 0 0:1a:30:2e:c2:b0
AP's Interface:1(802.11a) Operation State Down: Base Radio :00:1a:30:2e:be:90 Cause=Heartbeat
I have checked for known issues but couldn't find any pertaining the issue or error message.
Could someody help or share any info to find way out to troubleshoot as what is causing this issue.
Thanks in advance.
