CBW150AX losing connection to management AP

[vhud-tv]

On a customer site I have installed 5 CBW150AX in a VLAN (mgmt VLAN is primary on switch port).

However, after some time, some access points are no longer seen by the primary AP.

Network connectivity is there (verified). IP-Adresses are:

• primary: 192.168.5.51/24
• 192.168.5.50/24
• 192.168.5.52/24
• 192.168.5.53/24
• 192.168.5.54/24
• 192.168.5.55/24

I can ping all devices. When I reboot a device, it is found, but after a while (days to weeks) it disappears from management.

Switches are SG/CBS Switches.

Wifi on the APs is working.

Any suggestions welcome.

I resolved the issue over the night. It seems to me that the issue was related to a failed upgrade process from 10.4.2.0 to 10.6.2.0.

I performed upgrades to 10.6.2.0 on the devices which could be reached. One of the member APs did not perform the upgrade. Thus I disabled PoE on the switch port and performed the upgrade for the first two devices. I then disabled PoE on the switch port the primary AP was connected which led to a new primary comming up, which showed no member APs until rebooting the primary. After upgrading I disabled PoE on this port taking the device offline and so on until all APs haf been upgraded. Then I activated the APs one by one.

Worked now instantly. I also connected a *new* unconfigured device, it upgraded and integrated itself into the environment as expected.
