Bridge mode is a configuration option to enable Transparent Bridging.

In 802.11a/b/g/n-type wireless networks

IEEE 802.11

IEEE 802.11 is a set of standards for implementing wireless local area network computer communication in the 2.4, 3.6 and 5 GHz frequency bands. They are created and maintained by the IEEE LAN/MAN Standards Committee . The base version of the standard IEEE 802.11-2007 has had subsequent...

, configuring bridge mode requires that the wireless side be configured to be a Station for a particular Access Point, so a configuration interface, often via an integrated webserver, is generally provided.

In wired networks, such as ethernet

Ethernet

Ethernet is a family of computer networking technologies for local area networks commercially introduced in 1980. Standardized in IEEE 802.3, Ethernet has largely replaced competing wired LAN technologies....

, bridge mode generally requires no further configuration, as both sides are peers.

While in this mode, the router basically accepts only one device and controls all network traffic dedicated to this device.
