Adding a Second DD-WRT Router as an Access Point

Here’s another in an ongoing series of posts not only for my five blog followers 🙂 but so I can remember some technical thing I’ve done when I need to do it again five years from now.

My router (“Router 1”) which takes the connection from the DSL modem is located in a terrible place for whole house wireless coverage. So I have a second router (“Router 2”) in a location to provide wireless coverage to the rest of the house, connected to the first router via an ethernet cable. Both routers have the wireless set to the same SSID and password, but different channels.

How did I set up Router 2 so that it’s part of the network created by Router 1, without creating a whole separate second network? This procedure is a good summary. Though actually for the flavor of DD-WRT on Router 2, the setup was a little different. The key here was to select “WAN disabled” and “DHCP forwarder” as shown in the screen shot below (click to enlarge). (Router 1 is a Netgear without DD-WRT.)

Both routers have the wireless set to the same SSID and password, but with different channels. So I can roam around the house freely, and my wireless devices will lock on the stronger signal, switching to the other wireless signal as needed. Success!
