Connection lost after disable VLAN

Montland

During my tests, I observed that after certain configuration changes, it is no longer possible to log in. The access point loses its connection, and the issue can only be resolved by performing a factory reset on the device. This behavior does not appear to be normal and should be investigated further.

A specific example: The issue occurred immediately after deactivating the VLAN function under the "VLAN Settings".

The access point is connected via the Zyxel switch

With VLAN 1 as native checked this means the AP is on a untagged network I have (on my NWA50AX PRO) changed this so my AP is on VLAN 4091 and native unchecked this means the AP must be on a the VLAN 4091 tag network.

Hi @Montland,

"As Native VLAN" is checked, that means the packet will be untagged.
