II-5 Virtual Controller - Wireless
This feature allows users to establish and manage a network of DrayTek devices connected by
Wireless or Wired links.
The network consists of one Root and multiple Nodes. Root controls this network and syncs
configurations to Nodes. Normally Root and Nodes use the same Wireless SSID/security, and
Wireless clients can connect to any of them.
For Mesh networks, Root is also the outlet to the Internet. All devices of a network are in the same
Group. The root can add a new Node to its Group or delete members from its Group. Users can
choose VigorMesh or EasyMesh to establish the Mesh network. If Mesh is disabled, a network with
wired links alone could still be established as long as AP Management is enabled.
Vigor router plays a role of Mesh root in a VigorMesh network.
Please note that, within VigorMesh network,
the total number allowed for mesh nodes is 8 (including the mesh root)
