The best investment I've ever made and one that really fixes my WiFi problems. UPDATE: There is a room in my house that is not receiving a radio signal, in short the previous owner built the room as an annex and lined the walls and ceiling with metal mesh making the room look like a Faraday cage. One CAT5e cable per room with one of these provides wired and wireless access even in a "cage" with no wall/ceiling access point. :)
