Excerpt: The Linksys WRT600N is the first 802.11n draft 2.0 router we’ve tested that can operate on both the 2.4GHz and 5GHz frequency bands simultaneously. It’s also the most expensive Wi-Fi router we’ve ever tested. We tested the router at its default settings: The 5GHz radio operating in 802.11n-only mode and the 2.4GHz radio operating in mixed 802.11b/g/n mode. (Both radios have access to the same integrated four-port gigabit switch.
Pros: Dual-band blows all other routers we've tested out of the water; Storage Link give ad-hoc NAS functionality.
