A client wants a wireless network in their large, old house with thick wall that kills signals. What’s the best way to implement? Here’s what I’ve come up with – attach a Buffalo hi power G router to the cable modem (located on the middle of 3 floors) and link 3-4 other identical buffalo router units to the primary via a WDS star config. I will be placing one on Buffalo unit on each floor. Will this work? Is there a better way to do this?
