A router running DD-WRT v24 is able to create a wireless bridge. The bridging mode is selected from a drop down menu on the Wireless > Basic Settings page.




There are several variations of bridging. Use the following to determine which type is best for you. See the linked tutorials for information and examples of the different bridge types.


Client Mode Wireless In this type of bridge, your DD-WRT router connects (using radio) to an AP (access point) or wireless router. The DD-WRT router creates a subnet LAN. The subnet LAN has clients connected to it with cable connections. (On the firmware page, the menu choice for this mode simply reads “Client”.)


Client Bridge In this bridge, your DD-WRT router connects to an AP or wireless router and extends the original LAN. No subnet is created. Wired clients connect to your secondary router. Both routers are in the same LAN.

If you don't require extending the range your wireless LAN, this is probably your best option. An example of this is hooking up one or two wired computers in a bedroom where there is no wired connection. The DD-WRT router is located in the bedroom and the computers plug into the router.

An advantage of a client bridge is having secondary computers obtain DHCP leases from your main router. Furthermore, you don't need to setup port forwarding on your secondary router. Security measures and access limits are controlled by the main router.


Repeater Bridge This bridge is like a client bridge, except it adds the functionality of extending the range of your wireless network. The range is extended because, presumably, the secondary router is some distance removed from the first. In repeater bridge mode, a wireless client can connect to either your main router or the secondary router (repeater bridge router).

Unless you need to extend your wireless coverage, it's probably not desirable to use this mode. Some of the radio bandwidth will be consumed by the repeater function.




Other modes not discussed here are AP, AdHoc and Repeater. Although these modes employ the router's radio, they are not considered to be bridges.
