I've heard good stuff about Buffalo never checked it out yet.. I will post my findings.. not sure why Linksys has so many versions of just a single router but maybe they have reasons.
I used to run two Linksys routers w/ Tomato one was a wireles bridge behind the other. Experimented with the Buffalo router mentioned. I have now sold both Linksys routers an run one Buffalo and have no need for the bridge on the network now the wireless quality improved that much. -- My grandkids ARE cuter than yours!
