We are seeing clients having random and unpredictable connection issues in housing facilities where we have Cisco 702Ws. We have debugs and a TAC case open, but it's been slow trying to determine root cause via those methods. We are running on 8540s and WiSM2s with Cisco controller code: 8.5.131.0. This sounds buggy, but we are not seeing this as a bug from Cisco and TAC has not been able to provide any analysis. Here is the "debug mac" of one client seeing the issue (the specific debugs immediately after successful authentication completes and the problem begins):
*apfReceiveTask: Sep 07 14:39:02.898: 0c:54:15:49:34:9b 0.0.0.0
DHCP_REQD (7) DHCP Policy timeout. Number of DHCP Discover 0, DHCP Request 0 from client
*apfReceiveTask: Sep 07 14:39:02.898: 0c:54:15:49:34:9b Interface Group was NULL.Number of DHCP Discovery 0 from client
*apfReceiveTask: Sep 07 14:39:02.898: 0c:54:15:49:34:9b 0.0.0.0 DHCP_REQD (7) Pem timed out, Try to delete client in 10 secs.
