Our IAP 205 doesn't respond to ARP broadcasts

We have a few 205 IAPs and they don't seem to respond to ARP requests from wired connection and neither from wired lan. Any idea what could be wrong with their configuration?

What's the output of the console on boot up of the IAP?

When you say "arp requests", what are you trying to do?

Trying to ping them. They respond intermittently to ping, but not always. I see a lot of destination unreachable messages for packets destined to them.

Hmm, I'm a newbie with Arubas, so I don't even know how to see that boot screen?

Are those APS present in the CAM/ARP table of the layer 3 switch?

No, they don't seem to appear there either. Other devices from the same network are in the arp table.

Do you have the AP plugged into ethernet 0?

Yes, that is the case. They respond sometimes.

A correction: I checked again and they actually show up in the ARP table of the switch. When pinged e.g. from workstation, the workstation sends ARP broadcast, but never receiving response from the device attached to the same switch. I still see the same IAP sending broadcasts itself, asking for MAC of other devices (IAPs) on the same network.
