Ease of Use

The wifi connection disconnected every once in a while. Even after upgrading the linksys firmware the problem didn't go away. Finally I installed DD-WRT firmware which did the trick. Now the signal is stronger and only disconnects very seldom. I love the router now.

Best 5Ghz Router for the price

by A customer on 8/22/2010

I had been looking for a 5Ghz router for a while since I live in an apartment complex where the 2.4 Ghz bands are all overcrowded, and this router has performed amazingly given how little I had to spend. The dual radios are nice, since they allow legacy devices to connect as well. Unfortunately, this router was dropped during Linksys's transition from the WRT naming scheme to the eXXXX naming scheme, but this router is far superior to the current e2000 (former WRT320N) in wireless performance.

Product Overview

Built for speed, the Simultaneous Dual-Band Wireless-N Router delivers double the bandwidth so you can enjoy movies, gaming and music more smoothly, with less lag, all around your home. Easy to use and set up; includes Mac setup wizard.

Experience faster wireless connectivity with fewer interruptions with two bands of Wireless-N, today's most advanced wireless technology. The 5 GHz and 2.4 GHz bands are designed to work separately yet simultaneously, so you can easily customize your ideal configuration - for example, use the 2.4 GHz band to surf, email and print while keeping the less crowded 5 GHz band free for time sensitive traffic like music, gaming and high-definition video.
