I have some issues reported by a customer that when they move locations they are unable to reconnect and/or get an ip address.
29 x IAP215
6.4.2.6 - 4.1.1.7
I have checked a couple of times when it was reported and there were 2-3 APs where none of the clients had a valid ip address and only 169.254. Each occassion was different APs. Rebooting the AP seem to resolve it and any client connecting to it gets a proper ip address.
At one point during the issue I was able to do a pkt-dump on dhcp and what I could see was the client requesting an ip address and the server responding. Unfortunately I could not verify the response was going back to the device over the wifi.
- port config on all aps checked and fine.
- helper address setup on switch
- address pool is nowhere near exhaustion.
- dhcp server is receiving the requests and responding
I will raise a TAC case for this as it is pointing to something up with the APs, but wondering if anyone has had similar issues.
