WiFi devices not getting IP, WiFi Interface "unplugged", vxlan interfaces missing

LHerzog

We updated WiFi AP Firmware 3 days ago. on one location with some AP55c clients connecting to a WiFi will not get IP addresses. I cannot even see the DHCP requests with packet capture.

I noticed the WiFi interface is shown as unplugged. When I noticed the issue, the Interface did not even have a MAC address (00:00:00:00:00:00).

So I edited, disabled, enabled the SSID and the interface. It remains in unplugged status. No luck, at least it got MAC address again by those changes.

Unplugged and no MAC Address:

After changing and re-applying settings back to original values:

any help on this please?

update 7.7.2021: noticed missing vxlan adapters on the HA nodes that came up after reboot of the nodes. See comments below.

    Seems like the APX is still talking to the Aux instead switching to the primary. That should be investigated by support, what is going on. Personally i moved most customers to Central wireless and VLAN for different matters.

    I found a workaround for the issue without booting both HA appliances finally:

    remove it from the AP group, then add again. From CLI output below you can see that the missing 8 vxlan adapters were only added after this change. Same would have happened when rebooting the primary HA node.

    both SSIDs that were not working are working now again. Clients get DHCP and Hotspot will appear. Web-Surfing is working either.
