Why don't you consider investing in wifi extenders? I have the wifi extender kit from devolo (try googling wifi extender kit). My Infinity BTHH5 is upstairs, one end of my wifi extender kit plugs into the upstairs HH via Ethernet cable then plugs into the mains socket, and the receiver (2nd part of the extender kit) is plugged into a mains socket downstairs. They're very good for getting wifi into 'out of range' areas in the house.
