Re: Router Replacement? As far as seeing what wireless signals are near you, passmark.com has WirelessMon software where you can see the signal strength, channel and other info. It's not free but has a 30 day free trial.
I found all routers in my neighborhood were on either channel 6 or 11 (seems to be a default). I switched to channel 1 and my wireless performance was a little better.
