DrayTek Vigor 2830VNP Wireless N Dual Band ADSL2/2+ Firewall Router with VOIP

DrayTek Vigor 2830VNP Wireless N Dual Band ADSL2/2+ Firewall Router with VOIP

The Vigor 2830VNP model features 802.11n wireless LAN specification and has been certified by the WiFi alliance for cross compatibility and WiFi compliance (including WPA/WPA2 and WMM).

The Vigor2830VNP model include a hardware co-processor for WiFi which can provide an increase of up to 40Mb/s for WiFi connections compared to our other models.

802.11n provides a total wireless bandwidth of up to 300Mb/s using new methods such as packet aggregation and channel bonding. Throughput depends on your own environment (factors such as obstructions, number of hosts and distance all make a significant difference), but actual transfer speeds of over 100Mb/s are achievable (based on our real world tests). In addition, 802.11n provides greater coverage and resilience to interference compared to previous wireless standards thanks to the MIMO technology and the Vigor's triple-antennae diversity arrangement. This offset arrangement of aerials provides offset paths between hosts so that interference can be overcome.

The Vigor2830VNP includes Dual-Band technology. Most commonly, WiFi operates in the "2.4Ghz" band but with the number of people using Wifi these days, all sharing the same channels as well as DECT and Bluetooth also using the same band, congestion is a real problem. Everyone has to share the same bandwidth, and 802.11n uses three times as much as previous technologies. The Vigor2830n 'Plus' models can be switched to use the 5.8Ghz band instead which is far less congested. If your laptop of wireless device does not support the 5.8Ghz band, you will need a add a USB 'dongle', also available from DrayTek.
