WLC 2006 DHCP locking up

We have a WLC 2006 that is setup to distribute IPs to wireless clients using the internal DHCP server. Occasionally, wireless clients can connect to the APs (four 1131AGs) but do not get IP addresses assigned.

Rebooting the WLC temporarily fixes the problem.

software version is 4.0.155.0

anyone experiencing this or know of a solution?

thanks!

Apparently, others have observed similar DHCP behavior.

You may want to read a related thread ("Wireless Clients eventually not issued DHCP through WLC4404") in the "General" conversation section.

Hi,

thanks for your reply. i did read through that one before posting my own and the difference is that the WLC is the DHCP server in our case.

Re: WLC 2006 DHCP locking up

this problem persists after upgrade to s/w 4.0.155.5.

I am also seeing clients Associate ok to the AP but in the "Auth" status it says "No"

These messages are appearing in the log:

10 Thu Oct 19 17:13:26 2006 Coverage Hole Detected for AP CafeAP whose Base Radio MAC is xx:xx:xx:xx:xx:xx. Number of Failing Clients 1

Any ideas? Anyone?
