Totally agree. A bad G link will still give as good as a GOOD B link. G will give 5 mbps even when it is close to not connecting and B requires superb signals to get 5 mbps.

I have quite abit of G out there. All the clients and ap's I install today are G. 60's is great, 70's work just fine too. 60's get top performance, 70' is still a great very fast connection and even low 80's beat B.
