I'm thinking about connecting back up my WRT54G v1.1 just to get some better 2.4 range in and outside my home. My WRT600n just doesn't seem to have the oomph!
I am admittedly a Linksys Router hoarder. Goodwill had a Linksys E2500 and WRT110 for $5 ea. Had to pick them up just to keep in my spare collection. I love a great deal.
