The DrayTek Vigor 2820Vn is a fully featured ADSL2+ modem and wireless router for advanced installations.

A next-generation ADSL wired modem combines with 3G wireless broadband in the Draytek Vigor 2820Vn wireless router. It can work as a central hub for business connectivity, thanks to assorted high-performance specifications that includes VoIP telephone ports, content-filtering firewall and VPN facilities.

For wireless local area networking, the Draytek Vigor 2820Vn uses three antennae to enable good coverage for 802.11b/g and draft-n Wi-Fi clients.

Its internal modem can be used for ADSL and ADSL2+ broadband connections, while a USB port allows the setup of a 3G wireless dongle. The HSDPA/GSM option on the Draytek Vigor 2820Vn can be used as the principal method of wireless distribution in locations that have no wired option; or as a failover that maintains connectivity only if the primary wired link should fail.

That single USB port can also be used for printer sharing; or even as a dial-up modem backup, if you plug in your own 56K USB modem device.

Internet news and reviews

Unlike most domestic wireless routers, the Draytek Vigor 2820Vn has all its ports and sockets arrayed across the front panel, along with a matrix of nine LEDs to denote operational status. On the back panel are three detachable aerials and the DC power inlet and on/off switch.

There are four LAN ethernet sockets available, although only the first offers gigabit speed connection; the remaining three are limited to 10/100Mb/s operation.

We tested the Draytek Vigor 2820Vn on an ADSL2+ line from Be Unlimited. Download speeds were fractionally higher than those from Be's own Thomson modem, averaging around 16.1Mb/s (against 15.5Mb/s), while upload was a little slower at around 0.8Mb/s (versus 1.1Mb/s from the Thomson).

Setup of the Draytek Vigor 2820Vn through a web browser window gives advanced control over the unit's many features, including bandwidth management, load balancing (when using more than one WAN connection), multi-PVC (permanent virtual circuit) customisation, and many wireless security configurations, from WEP to WPA2 with AES or PSK encryption.

We found one issue with uPnP port forwarding failure, as the Draytek Vigor 2820Vn would not allow Back To My Mac remote access sessions to be started through Apple's MobileMe service.

Build quality of the Draytek Vigor 2820Vn hardware is high and the unit never got noticeably warm in use.
