WSR-1166DD Wireless Bridge Configuration

[TheDonovan]

Buffalo states on the product page:

WIRELESS BRIDGE

Configure two or more AirStation AC1200 Gigabit Dual Band Open Source DD-WRT NXT Wireless Routers to act as a standalone wireless bridge. Create a permanent, high-speed wireless link capable of speeds up to 866 + 300 Mbps and wirelessly extend the range of your network.

There is a switch on the back of the router "WB" to place the router in Wireless Bridge mode however there is no documentation on how to make these routers connect in this mode. There is no documentation in DD-WRT NXT Wiki on how to do this nor does Buffalo Level 1 tech support know how to do this.
