DrayTek Wi-Fi Solutions

In the age of Internet and Intranet, Small to Medium Businesses (SMBs) all over the world need to connect devices to each other (Local Network) and to the outside world (the Internet). They need reliable network connections for the LAN and the WAN, and more importantly, the functions that allow the businesses to tick without missing a beat. These include security in access control, Firewall protection, Load Balance/Failover in case things go wrong, and capability to access files securely from anywhere, etc. Among all these functions, Wi-Fi, or Wireless LAN, have become a key technology SMBs rely on for fast deployment of network devices and sharing of resources.

With unique DrayOS firmware, DrayTek Corp. leads the field with business level routers that not only fulfil the basic requirements for LAN and WAN connectivities but also support business applications for the SMB market. Among these business applications, DrayTek continues to bring about state of the art Wi-Fi solutions to support the SMB market. Below is a list of these Wi-Fi solutions:

Central AP Management

Central AP Management (APM) provides a convenient and easy way to manage, monitor and configure up to 20 DrayTek Access Points (AP) in a local network from a central console.

With Central AP Management, AP profiles can be preconfigured on the router, and when a new AP is connected to the network, this configuration can be pushed to the AP. Other functions include:

  • Upgrading firmware
  • Backup and restore configuration
  • Monitor the traffic status
  • Rogue AP detection tool to mark an AP as friendly or rogue AP
  • AP load balance

Central AP Management is an integrated feature in Vigor2860, Vigor2925, Vigor2952 and Vigor3220 series routers.

Central AP Management supports up to 20 Wireless Access Points




Multiple SSID and VLAN

Multiple SSIDs allow the administrator to create logical networks to service different workgroups or guest users. For example, you may provide restricted free Wi-Fi access for guest users and secure Wi-Fi
for different departments within an organisation.

You can use the VLAN feature in DrayTek wireless routers and Access Points to separate your private network from the public network.


Operation Modes (for Access Points)

In Wi-Fi deployment, the signal strength and distance coverage are always the most important factors to consider. DrayTek’s Wi-Fi solution provides the following Operation Modes to cover various situations:

  • AP: AP acts as a bridge between wireless devices and wired Ethernet network, and exchanges data between them.
  • AP Bridge-Point to Point: AP will connect to another AP which uses the same mode, and all wired Ethernet clients of both AP s will be connected together.
  • AP Bridge-Point to Multi-Point: AP will connect to up to four APs which use the same mode, and all wired Ethernet clients of every AP will be connected together.


  • AP Bridge-WDS (Wireless Distribution System): AP will connect to up to four APs which use the same mode, and all wired Ethernet clients of every AP will be connected together.
    This mode is still able to accept wireless clients.For example, the AP Bridge – WDS mode extends the Wi-Fi internet access over a large area across office buildings or warehouses.
  • Universal Repeater Mode: As a universal repeater, the VigorAP will connect to the main Access Point and accept wireless clients at the same time, and therefore can extend signal coverage of the main Access Point.universal-repeater-operation-mode


Security and Access Control

Wi-Fi security is vital to prevent unauthorised users from stealing bandwidth from your Internet connection or accessing your network and confidential data. Draytek wireless routers and access points
provide WPA and WEP encryption to secure access to the Wi-Fi network. For higher level security, you can use the WPA/802.1x security method.

Security can be further enhanced by enforcing access control using the MAC address Filter to allow known devices to establish a connection. For example, to allow certain devices to access Wi-Fi SSID 1, you can add these to the white list. So any devices that do not have a matching MAC address will be denied access to SSID 1.  On the other hand, you can use the Black List to allow any device to connect to the SSID except for the device with a matching MAC address.


Wi-Fi Hotspot Web Portal

DrayTek’s Wi-Fi hotspot web portal provides an easy and convenient method for a business to provide free (or paid) Wi-Fi access to their customers. Customers can log in using their social login accounts (Google and Facebook) or by use of a PIN code. This eliminates the need to create multiple user accounts to provide free Wi-Fi access and makes it easier for customers to use your services.

The web portal page can be customised to the business requirements to display the business logo, background image and provide login methods.

You can set up free/paid Wi-Fi access for customers to your business and have some control over what they can do in your network. In addition, you can direct customers to your web portal to view services or products you have available as well as any promotions you have running. Access to the Internet can also be controlled by use of the firewall features to prevent unauthorised use of your network services.


Sample Web Portal Pages



DrayTek VigorAP 900 and VigorAP 902 access points include roaming capability.

There are two roaming methods:

  1. AP-assisted Client Roaming. This will disconnect an attached Wi-Fi device when a minimum threshold is reached and an adjacent access point is available to take over the connection. This provides uninterrupted Internet access when moving from one access point to the next.
  2. Fast Roaming (WPA/802.1x). This method uses Pairwise Master Key (PMK) caching where Access Points and Wi-Fi devices maintain the Pairwise Master Key Security Association PMKSAs for a period of time. This speed up re-connection when a Wi-Fi client roams away and –back from an access point.

Airtime Fairness

The Airtime Fairness feature overcomes the problem where slow Wi-Fi devices reduce network performance, putting faster Wi-Fi devices at a disadvantage. It provides equal airtime to all devices with
the resulting improvement in Wi-Fi performance. This option is useful in environments with a mix of 802.11ac, 802.11a, 802.11n and 802.11g Wi-Fi devices.

For example, in the diagram below, Client B uses only ¼ of the time compared client A, but only allocated ¼  of network time. With Air Time Fairness, both clients are getting same time for transmission. As client B is faster, it can transmit 4 times as compared to client A. Client A transmits the way it was doing before. The result of this technology is that the network performance will improve.
