9.9 Uplink Detection

In AP mode, the AP connects to its upstream network using the LAN0 port. If a critical node

between the LAN0 port and the upstream network fails, the AP as well as the wireless clients

connected to the AP cannot access the upstream network. If uplink detection is enabled, the AP

regularly pings specified hosts through the LAN0 port. If all the hosts are not reachable, the AP

stops its wireless service and wireless clients cannot find the SSIDs of the AP. The client can

reconnect to the AP only after the connection between the AP and the upstream networks is

recovered.

If the uplink of the AP with uplink detection enabled is faulty, wireless clients can connect to the

upstream network through another nearby AP that works properly.

See the following topology (The LAN0 port serves as the uplink port).
