In addition to combining an ADSL modem with an 802.11n router, it also allows the connection of a USB 3G modem as an alternative link with automatic failover or to allow operation at a temporary site.
On top of that, it acts as a two-line VoIP adaptor with a single FXO port allowing the handsets to share a normal phone line.
An unusual feature is the serial port for attaching a console device.
The Quick Start option in the web interface simplifies initial setup, and even includes details for several local VoIP providers so all you need to enter are your account details instead of messing with arcane technical details.
The overall arrangement of the web interface seemed clearer and more logical than the bulk of the products tested here.
The device logs inbound and outbound VoIP calls (including any missed calls) as well as the usual system and firewall events.
Talking of the firewall, it comes with three preconfigured settings (low, medium and high security) or you can roll your own set of rules. In addition to the rules-based firewall, the 7404VNOX makes it easy to block instant messaging (MSN and Yahoo) and peer-to-peer (BitTorrent and eDonkey) traffic.
Other upmarket features include VPN, WDS and Gigabit Ethernet.
The documentation is reasonable, but as usual assumes a greater degree of familiarity with networking concepts than is reasonable these days. Manufacturers don’t seem to have realised that ‘ordinary people’ set up small networks, and they may require some guidance - especially concerning the more advanced features of a router.
And the phrasing needs attention, for example “The input format is in character style and key size should be in the range between 8 and 63 characters.”
Wireless performance - at least as measured by our tests - was mixed. The 7404VNOX was one of the fastest routers over shorter distances. But file transfers at long range were slower than we expected. Average times recorded were 3, 19 and 73 seconds.
The 7404VNOX conveniently bundles multiple functions into one reasonably compact case. Just beware of paying for features you don’t need.
