Just noticed something interesting yesterday. I had a single client connected to an IAP-215 with the IAP connected directly to a PC via ethernet (test environment).
I noticed when running "show clients" via the CLI that the client appeared as expected, but the signal strength and speed where both listed as "0 (poor)".
However, I could still ping and communicate with the client from the test PC without any issues. The RSSI of the AP as read by the detector was also very strong and showed that it was connected.
After about 25 seconds the signal went up to "52 (good)" which is what is expected in the lab environment.
The client had been in a powered-down state and just powered up. I had a script checking the client signal strength every 3 or 4 seconds.
I've seen this happen once before, so twice now in several weeks. It's a pretty rare occurence in the lab, but have seen it multiple times now.
About how long does it take the client list to update in the CLI? What might be causing the delay in updating the signal strength/speed fields for a client?
