LAP1142N cycling IP addresses from DHCP

Hello everyone,

  I have a LAP1142N that is connected to a 3560 nonPoE switch (using compatible power injector) that will not associate to the controller I have set-up. The wireless is existing and I have about 11 other APs connected to the controller with no issues. The AP will pull an IP address from DHCP running on the primary controller. The AP pulls a new IP address in roughly a minute. I set the pool to be 3 IP addresses and set a contant ping to each, there is about 1 request time out before the next IP address starts pinging. I went to the controller and pulled the following message error from the log.

*Feb 13 14:24:58.614: %LWAPP-3-HDR_ENCAP_ERR: spam_lrad.c:4216 Unable to encapsulate LWAPP header for discovery response; AP (APs MAC address)

*Feb 13 14:24:58.614: %APF-3-PDU_ENCAP_FAILED: apf_net.c:771 Failed to encapsulate a PDU for transmission to station00:00:00:00:00:00. Destination IP address not set in L3 mode.

I have tried a different cable, connecting to a PoE switch, different controller, larger DHCP range, hosting DHCP on the distribution switch, I am awaiting console access to the AP since this is remote work. The controller is running Software Version 5.1.151.0. Thoughts?

The 1142N is a CAPWAP based AP and requires your WLC be running a minmum of a 5.2 release.

You will need to upgrade your WLC to support the 1142N.  What other models of APs do you have joined?

The other APs in use at the site are 1242AG's. Will reply once the software get upgraded. thanks for the input.
