Fairly new to the Office-Extend arena, but I have two Air602 OEAP units for testing. Overall functionality is great but I do have one slight annoyance.
While i'm connected to the "Corp" ssid, the one pushed from my WLC, it will occasionally drop my connection. My Wireless NIC will sit there and sent ARP broadcasts and get no response, this lasts for about 30-60 seconds and then everything will reconnect like nothing happened.
This is only an issue on my Office Extend AP, my LWAPP in the office dont do this to me. I have verified that the problem is not linked to just my PC. I have another laptop that I tried at home and got the same behviour.
I did a packet capture during the "silent" period and i see my wireless adapter sending packets, but getting no responses. The controller doesn't see the Ap disconnecting nor do my clients disassociate or see the SSID disappear.
I've verified it's not my internet connection at my home because I had a client on the "local" SSID on the AP as well as the "Corp" SSID, the corp ssid client lost connection while the local SSID client maintained internet access without any interruption.
My 5508 WLC is on my "internal" network behind an ASA running 8.4(3). I thought maybe the firewall was an issue so I tried another non-Cisco firewall as well and got the same behavior.
WLC: Cisco 5508 22.214.171.124
AP Type CAPWAP
AP Model AIR-OEAP602I-A-K9
OS Version 126.96.36.199
I dont see an OS upgrade available under CCO downloads for the AP. Any ideas where I should start to look for this?. Thanks.
I'm seeing a similar issue running the 188.8.131.52 code. However, it's only happening (or being reported) for mac users. And it can go well beyond 30-60 seconds. It can go on indefinitely sometimes until I disconnect and reconnect to the SSID. My SSID does show connected, but similar to your experience, no arp responses from the default gateway. I did a packet capture to see this. Interestingly, not long after starting the capture I see some EAPOL packets come in and suddenly it starts working. So would seem that 802.1x is blocking the port and for some reason I'm not re-authenticating. I tried disabling session time out, but that didn't solve it.
Here's the packet trace where it's not working then suddenly starts working:

This is the start of a display filter cross reference between Wireshark and OmniPeek.
The 1st installment is a table of advanced filters. More filters will be added as time allows.

I have created a Powershell script to automatically add a Wireless Guest User on Cisco WLCs. (tested on 2500 Series)
The script should be completely self explanatory.
