Pre-802.11n, Functionalities: VPN Pass-Thru, Firewall, Voice over IP Gateway (VoIP), WAN: 1 x 10/100/1000 Base-T, LAN: 10/100/1000...
The Duo technology in the DIR-855 supports dualband (2.4GHz & 5GHz) wireless signals at the same time. This allows you to check e-mail and browse the Internet using the 2.4GHz band while simultaneously streaming High-Definition (HD) movies and other media on the 5GHz band. The DIR-855 is designed for users looking to get a true HD wireless connection that can handle multiple HD video streams throughout the house, while being backward compatible with your existing 802.11g and 802.11a products.
Although it’s not a screamer at short range, the good long-range performance (at 5GHz at least) makes the Linksys WRT610N an attractive choice
The DIR-855 is among the fastest wireless routers in our tests and would be particularly attractive to all-Windows networks.
A good demonstration of the benefits of 802.11n, and a good choice for offices requiring a basic router.
Although the basics of this router are somewhat low spec (no 802.11n or Gigabit Ethernet), the extras do make it interesting.
