Ideally, you would hardwire the second device to your WRT and set it up as an access point. Are you implying that you can't run a wire to the second floor..
I am going to try that, hopefully I can position the N router(set as an access point) so the signal upstairs is better without moving all of my original equipment
both routers are several years old, do the newer ones(without going high dollar) have better range?
