A wireless security system with good roaming support, but it isn’t perfect

Not a great performer in testing, but a firmware update that delivers the performance we saw with the TL-WR841ND would make it great value.

Although the basics of this router are somewhat low spec (no 802.11n or Gigabit Ethernet), the extras do make it interesting.

An expensive route, but the Netgear Prosafe SRXN3205 provides the reassurance of of an SSL VPN along with a long warranty.

Respectable performance and a security assistant makes the Belkin N1 Vision a good contender for a small office.

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.

The especially full feature set of the 7404VNOX makes it stand out from the crowd.

An older router missing a couple of key features, but worth considering for a small office equipped with older and slower Wi-Fi and Ethernet equipment.

A good demonstration of the benefits of 802.11n, and a good choice for offices requiring a basic router.
