Hi, if I get an AC router and an AC extender, then connect to the extender using a device on N, will the extender run my N transmission back to the router at AC speed? Or does it revert to N? My problem is that I have a 2 story house. My modem and router are on the second floor at one end of the house, roke and tv are on first floor at other end. I currently have an N router and extender, and it just doesn't work worth a darn. Any other config that folks could think of here? Can a poweline go across circuit breakers?
