we had the problem, that our mobile devices (Orderman) in an restaurant, sometimes brake the connection and must be restart to conect again. In the Notifications we see the messages disconnect-info [ap-sent-disassoc-with-code-2] and disconnect-info [ap-sent-disassoc-with-code-2]. Anybody an idea what the problem happens?
It normally connects to one AP without duplicated AP's. But when I set it on the main network, I get [ap-sent-disassoc-with-code-2] while connecting. 802.11r is disconnected on that network, and band is 2,4 with auto channel selection.
We are having the same issue and we sent the info to support which they gave me the answer of hard setting the channels . We also had the same error codes.
If support finds an issue please post it. I can't imagine there was no fix.
