I just set up DD-WRT on my new WRT320N (thanks to those who suggested it). I got an antenna kit and a big heatsink/fan and it works GREAT. Friends have already said that my wifi seems WAY better than with my DIR-655. Anywho, I'm fairly familiar with DD-WRT, but I want to pick the best TX power. I hear it's about balancing signal and noise to get the best throughput, basically. Is there a QUICK and accurate way to figure this out? I don't really want to copy files back and forth in 1mW increments... Thanks!
