APs go into standalone but don't recover

Unanswered Question
Aug 27th, 2009

We have an issue of APs losing communication to the WLC, going into standalone mode and not completely returning to LWAPP mode once communication is restored. The controller is a 4404 running version 5.2.178.0. The WLC is at our corporate office and the APs are scattered around the country at small sales offices. We are running H-REAP to the 1242 series APs.

If the WAN link drops or the site loses power, the AP loses communication to the WLC (obviously). When the WAN/power restores, the AP restores communication to the WLC, but clients connecting get 0.0.0.0 as an IP. The local router at the site hands out the DHCP addresses. The fix has been to bounce the PoE switch port or rebbot the AP from the WLC. Removing power to the AP is the best recovery right now. Any ideas how to fix this issue? Thanks

I have this problem too.

I contacted my Cisco Rep regarding the above mentioned Bug ID and was told that the bug is tied to version 6 of the WLC code. So that doesn't pertain to me since I am using version 5.

Has anybody else experienced the issue of clients not getting an IP address after the AP is required to re-establish communication to the WLC?
