Overview

In AP mode, the AP connects to its upstream network using the Ethernet port (LAN port). If a critical
node between the LAN port and the upstream network fails, the AP as well as the wireless devices
connected to the AP cannot access the upstream network. If uplink detection is enabled, the AP
regularly pings specified hosts through the LAN 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 LAN port serves as the uplink port).
