Problems with AP205 & AP105 APs in an Instant cluster

We recently (end of January) added a AP205 to an Aruba instant cluster which contains 6 AP105s in addition, and are now experiencing problems on the WLAN when the AP205 is plugged in and active.
  - The problems start within about 45 minutes to 2 hours after the AP205 becomes active in the cluster, with users complaining about slow/unreliable/intermittent service.
  - When IT support then investigates, they discover high latency and packet loss over the WLAN, even to services on the LAN.
  - Sometimes, all the SSIDs also dissappear from the air (i.e., they are not discoverable) for a short period (30 seconds to about 2 minutes).
  - The only way to resolve these problems are to reboot all the APs, but this is however just a short term solution as the problems start again within about 45 minutes to 2 hours.
  - The only permanent solution/work around found so far is to remove the AP205.
Does anyone have any ideas on what the issue could be?

What version of Instant is this?

Are you using broadcast filtering on that network?

Have you tried making the AP205 the preferred master?

Do you know which version of the firmware you're running? We have both sets of APs in the lab and I'll see if I can reproduce it...

I'm wondering if this issue is related.. I have a TAC case open:


Do the management interfaces also drop? I had to setup a syslog server to get the info to TAC.


If you can't get an AP tech drump from the weGUI (which I couldn't due to high CPU consumption), it was suggested that I could try to grab and AP tech dump from the console.
