We have recently installed 13 AP250s in our office. 2 of them had CAPWAP issues. Initially manual reboot of the switch port fixed the issue but eventually they went to an inaccessible state even from CLI. The logs showed that APs are frozen during reboot procedure and we received new APs as replacement. Today another AP lost the CAPWAP connection and is not coming back online. The event happened at 3:48 AM when there is no traffic at all. Another kind of issue is that whenever I update and upload a config to a Test AP, the test AP always loses CAPWAP connection and wouldn't come back. From CLI access, it is noticed that if I configure the management IP and VLAN again manually then it would come back online. I wanted to know if anyone else has the same stability issues.
