Reliable and High-Performance WiFi ('n' models only)

The Vigor 2850 Series 'n' models feature 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 Vigor2850n and Vn models includes 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.

Selectable Dual-Band

The Vigor 2850n and 2850Vn 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 Vigor2850n

and Vn 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.

Wireless Security

The Vigor 2850 Series provides several independent levels of security including encryption (up to WPA2), authentication (802.11x) and

methods such as MAC address locking and DHCP fixing to restrict access to authorised users only. The Web interface lets you see how

many and which clients are currently connected as well as their current bandwidth usage. An 'instant' block lets you disconnect a wireless

user temporarily in case of query. The Wireless VLAN facility allows you to isolate wireless clients from each other or from the 'wired'

LAN.

The Vigor2850 wireless versions also allow guest access with password protection so that visitors can use your WiFi access, but only with

a password which you set for them. When the user connects to your wireless LAN, they are firstly presented with your login screen before

any Internet access is permitted. This is in addition to any encryption system you have running.

The Multiple SSID features enable you to have up to four distinct or common virtual wireless access points. For example, you could have

one for company usage, with access to your company LAN and another for public access which allows internet surfing only. Setting up

wireless security is made easier thanks to the WPS feature (WiFi protected setup) whereby your client PC can get it's security keys by

pressing a button on the front of the router.

If your laptop PC's built-in wireless doesn't support 802.11n wireless or the 5.8GhZ band and you want to take advantage of that, you

can use the optional Vigor N65 USB adaptor.

For specialist or more demanding coverage applications, optional aerials can be used with the Vigor 2850 to potentially increase the

range of wireless coverage (depending on environment) or provide directional coverage in order that your wireless transmission is

focussed and concentrated into one direction only, for example into a room or across open space. With the increasing popularity of

wireless LANs, you will want to choose the least congested wireless channel (Nos. 1-13) for yours so the Vigor can scan and provide a list

of all devices in the vicinity so that you can choose the best channel (see screenshot below).

 802.11n Compliant

 Switchable Dual-Band (2.4Ghz or 5.8Ghz)

 Hardware wireless co-processor for increased throughput

 'MIMO' Technology with three aerials (2T3R) for diversity

 Packet Aggregation and Channel Bonding

 Optional Higher Gain or directional aerials available

 Also Compatible with 802.11b and 802.11g Standards

 Active Client list in Web Interface

 Wireless LAN Isolation (from each other and/or wired LAN)

 64/128-bit WEP Encryption

 WPA/WPA2 Encryption

 WPS - WiFi Protected Setup for client security setup

 Switchable Hidden SSID

 Restricted access list for clients (by MAC address)

 Time Scheduling (WLAN can be disabled at certain times of day)

 Access Point Discovery

 WDS (Wireless Distribution system) for Bridging and Repeating

 802.1x Radius Authentication

 Wireless Rate-Control

 Automatic Power Management

 802.11e WMM (Wi-Fi Multimedia)

Above : The Vigor2820n provides a local survey of other

access points so that you can choose the least congested channel.
