Hi
I have some troubles with one of my clients on my wireless networks.
The session timeout on my WLC is 30min. per default and the clients gets disconnected every 30 min as expected. But this one client takes about 1-2 minutes before i reconnects.
Is there any reason for this or is it a client problem?

Feb 21 09:30:35.623 *apfReceiveTask Client expiration timer code set for 10 seconds. The reason: Client was marked for deletion, and it was on associated, power save or blacklist state. Other message would provide reason for delete
Feb 21 09:30:45.623 *apfReceiveTask Client disassociation event has occured. Possible reasons may be due to AP Radio Reset usually due to channel change or wlan was manually disabled or Client unable to get valid DHCP IP for WLAN using DHCP required
