4. With EA4500 on channel 157 (40 wide), I was getting 3 times the transfer speeds of my older WRT160N. While the 2.4 Ghz looked better as far as signal-to-noise ratio, it was competing HEAVILY with 24-25 other wifi networks. The 5Ghz range was fairly clean in my area. The transfer speeds (practical test) proved to be better here.
