I am experiencing a problem at a couple of customer sites. I have the WLC configured to point to a Microsoft DHCP server. Periodically, all of the clients will be unable to obtain a DHCP address. Currently, the only fix I have been able to come up with is to reboot the WLC. Obviously, this is not the desired solution. Has anybody experienced this problem and been able to permanently fix it?
What version of the OS and client software are you using?
Have you done a bug check on CCO?
On the clients, are you using the vendor's client software, or MS Zero Wireless Config?
Let us know
I have the exact same problem. The 4404 passes the DHCP addresses from the DHCP server to the clients until it just stops. The clients appear to be connecting, but then return an error of "this connection has limited or no connectivity". That is my sign to go reboot the controller. There isn't a bug listed for it yet and I need a patch or fix if anyone has it. Thanks!
We encountered the same issue and were told by Cisco TAC to use the local DHCP server. The engineer said it was a bug that should be fixed in January.
and when i put comm 'sh dot ass'
i see a next screen
0004.6147.a875 172.16.3.236 unknown - self As
0004.6169.de1f 0.0.0.0 unknown - self As

i have just one AP1231G, but my problem same too - wireless clients not obtaining IPs periodic from external DHXP server (freeBSD)
With wired clients working good
I talked to the TAC and they said this is an issue with 220.127.116.11 and they are working on a fix. The alternative is to use the internal DHCP server on the controller. That isn't an option at this client, yet; but I am looking forward to a fix as this is quite frustrating to reboot randomly to fix it.
