Unlike a WDS, your DD-WRT router can now receive and redistribute a wireless signal from a generic AP.Typically, you would use wireless repeater mode to rebroadcast a signal too weak for your wireless clients to pick up reliably – assuming that your DD-WRT router can pick up the host AP, of course. Thanks to the new V24 beta firmware, a single DD-WRT router can be set up as a wireless repeater. In the real world, you might own only one router which can run DD-WRT. For the most reliable results, each router should be the same model running the same firmware. At a minimum, each router in the network must support WDS. In fact, we earlier demonstrated precisely how to do it our second DD-WRT tutorial. Setting up a WDS is a perfectly respectable thing to do. But those days are gone – and by “those days,” I mean 2006. In the old days, when you wanted to extend the range of a wireless access point, you had to set up a WDS, or wireless distribution system, coordinating two or more WDS-capable routers.
