As part of my ongoing battle against my speed issues, I decided to pick up a new router. I'm convinced that the Actiontec doesn't have a great wifi signal. I get 4 bars less than ten feet from it. I picked up an TPLink Wireless-N router from Amazon, and I've got it set up and working. My question is, what settings should I change on the Actiontec to get the best perfomance? I've turned off the radio, but I'm sure there are some that I'm missing.
