The Vigor2866 series routers support multi-WAN with one xDSL WAN port and one configurable Ethernet WAN port. The built-in xDSL modem is compatible with VDSL2 including profile 35b supervectoring, ADSL2+, and G.fast which can deliver fibre-like speeds up to 1 Gbps. The WANs can be configured in either load-balance or failover modes to maximise Internet bandwidth and up-time.

Higher Transmission Efficiency with OFDMA
OFDMA has been used in LTE for many years, and is now available in 802.11ax for multi-user mode.

With legacy OFDM, each frame is transmitted across the entire channel width. When the transmission rate is low, this causes more latency and jitters and lower the overall efficiency.

OFDMA splits a single frame into groups of subcarriers, and each subcarrier can be sent simultaneously. With multiple access mode, it allows multiple users to transmit at the same time thus improving efficiency and enhancing user experiences in high density environments.

802.11ax (WiFi 6) BSS Colouring (Vigor2866ax only)
In traditional 802.11 Wi-Fi networks, access points are designed to wait and take turns if other signals of the same frequency are detected from adjacent access points. This sharing of a resource, in this case radio frequencies, is called a basic service set (BSS). 802.11ax adds Colouring to the BSS information being broadcast so that APs can use the same channel at the same time without having to take turns. This increases Wi-Fi efficiency, particularly in high density environments.

An 802.11ax AP using BSS Colouring has the ability to change its BSS Colour if it detects another AP using the same BSS Colour on the same frequency.

Assisted Wi-Fi Roaming – built-in in selected Wi-Fi Vigor Routers and all Vigor Access Points

Extend Transmission Range
When a Wi-Fi client moves out of its effective transmission range which is defined by the Basic Rate and/or Received Signal Strength threshold, the AP forces the Wi-Fi client to pick up a nearby access point with stronger signals thereby extending the range.

Improve Data Rates
When the “Minimum RSSI with Adjacent AP” option is set, APs or routers on the same local subnet will exchange client information with each other and switch to the AP or router that has the strongest signal, ensuring that data rates can be as good as possible.

Better User Experience
Instead of ineffective transmission with low basic rates or RSSI, the better links provide better user experience while saving the airtime.

No Controller Required
Assisted Roaming is a built-in feature in all Vigor Access Points and a number of Wi-Fi routers; it saves the need for an ad-hoc wireless controller and is an ideal solution for simple network deployments.

Router Spec -

Load Balancing
Maximise throughput and reliability by using multiple Internet connections.

xDSL Modem
Integrated xDSL modem supporting G.fast to deliver fiber-like DSL speed.

VPN (Virtual Private Network)
Build a secure and private tunnel from the LAN of the Vigor2866 Series to remote offices and teleworkers over the Internet.

SSL VPNs work through firewalls providing secure remote access to any network environment.

Bandwidth Management
Prevent one device using all the bandwidth with bandwidth limit policy, session limit policy, and QoS settings.

Firewall & Content Filter
Filter web pages by URL keywords or web category to block access to insecure or inappropriate content.

VoIP Friendly
The Vigor2866 Series can do port forwarding and reserve bandwidth for VoIP traffic automatically, making VoIP setup effortless.

Free DDNS service to access the router using a fixed hostname of your choice.

Central AP Management
Use the Vigor2866 router as a wireless controller to maintain and monitor VigorAPs.

Central Switch Management
Set up VLANs easily from the router and get a centralised hierarchy view of the switches.

Hardware Acceleration
Without sacrificing traffic control features such as QoS, Bandwidth Limit, WAN Budget, Traffic Graph and Data Flow Monitor, Hardware Acceleration enhances performance for:

NAT & routing connections

Hardware NAT & Routing
With Hardware Acceleration and Hardware QoS enabled, the router supports up to 8k NAT and routing connections, and firewall performance reaching 940Mbps on single WAN and 1.8Gbps combined performance on multi-WANs.

Hardware QoS
Hardware QoS allows prioritization of applications and services on DrayTek routers, to improve performance of critical applications such as VoIP, conferencing and video streaming, etc. Furthermore, it allows flexible bandwidth allocation to suit business requirements.

Hardware IPsec
While the Vigor2866 series already has improved IPsec performance over the previous Vigor2862 series, with Hardware Acceleration enabled, IPsec performance can now reach 800 Mbps. The first 16 tunnels are automatically accelerated on a first come first serve basis. If any drops out, a new tunnel will be put into the accelerator automatically to top off 16 accelerated tunnels.

Application QoS allows prioritisation of applications and services on DrayTek routers to improve and enhance critical applications such as VoIP, conferencing and video streaming, etc. It also allow flexible bandwidth allocation to suit business requirements.

VoIP First
VoIP is always a top priority! The default VoIP port, UDP 5060 (configurable) has priority out-of-box with QoS.

Improve Experience for Business-Critical Apps
Select your business critical apps, and easily put them into QoS classes.

Flexible Bandwidth Allocation
Bandwidth will be reserved for high-priority classes, and can be used by low-priority classes when available.
