Router - A device that connects two or more portions of a network at the Network Layer (OSI Layer 3).
NetworkBridge - A device that connects two portions of a network at the DataLink Layer (OSI Layer 2). With regard to a wireless router, "bridgemode" means the routing functions are disabled, and the device connectsto an existing wired network to provide wireless access.
AccessPoint - A device that acts as a hub in an IEEE 802.11 wireless network.Client devices such as computer wireless cards can connect to an AccessPoint, and then can connect to other network services such as hardwiredservers or the Internet.
Wireless Distribution System(WDS)- A system that enables the wireless interconnection of AccessPoints in an IEEE 802.11 wireless network. This allows WDS-enabledAccess Points to connect together wirelessly, usually to expand therange of the wireless network.
As you can see, "Wireless bridging" is a very confusing term. This is why we stick to using the term "WDS".
Buffalorouters (and indeed most other consumer routers) are multiple devicesmelded into one. A typical Buffalo router is a Router, Access Point,Switch, and also can be configured in "bridge mode". WDS is an entirelyseparate feature, only supported on some models.
