there are now
extenders out.. should get you much higher speeds than 1.1. I'ld make sure all your routers/extender have gigabit ethernet to support the higher speeds though.. while your internet might only max at much lower speeds, having a gigabit network at the house is quite useful- we use a NAS for music/photo/video storage and went to a gigabit network last year and I have been really happy with the uptick in performance...
