WDS (Wireless Distribution System)

From wiliGear wiki

Jump to: navigation, search

NOTE: This document describes WDS configuration for Wili-S 4.0, Wili-S 5.0 and later versions, using Atheros 5.x and/or Madwifi-ng driver. For Wili-S 3.5x (using old madwifi driver) use Wili-S 3.5x WDS configuration.

Description

WDS (Wireless Distribution System) is a Wireless mode that enables wireless bridging in which WDS peers can communicate with each other without association, and/or wireless repeating in which APs and/or clients communicate both with each other and with wireless stations. WDS peers are used to bridge two or more wireless service sets (networks).

  • There's no such thing as a WDS peer.
  • If needed only to bridge 2 wired networks - use Wireless ACL (Access control list) configuration to prevent undesired association of other clients.
