Fig. 37. Link integrity settings.

When the SMC2582W-B is in AP or Bridge Master mode and the Ethernet LAN interface is detected to be disconnected from the wired network, all currently associated wireless clients (STAs and Bridge Slaves) are disassociated by the SMC2582W-B and no wireless client can associate with the SMC2582W-B.The detection mechanism is based on pinging the IP address specified in Reference host.

3.5.1.3. Wireless Distribution System

Fig. 38.Wireless Distribution System.

Traditionally, access points are connected by Ethernet. By IEEE 802.11 Wireless Distribution System (WDS), APs can communicate with one another wirelessly. For example, in Fig. 38, AP 2 acts as an access point for the notebook computers and it forwards packets sent from the notebook computers to AP 1 through WDS.Then, AP 1 forwards the packets to the Ethernet LAN. Packets destined for the notebook computers follow a reverse path from the Ethernet LAN through the APs to the notebook computers. In this way, AP 2 plays a role of “AP repeater”.

Fig. 39. LAN-to-LAN bridging.

By WDS, two or more LAN segments can be connected wirelessly. As illustrated in Fig. 39, a pair of wireless LAN-to-LAN bridges is used to connect two LAN segments. Since the SMC2582W-B is WDS- enabled, it can be used as a wireless bridge even when it is in AP mode.
