What wireless mode can be used to configure WDS?

The mode suitable for configuring Wireless Distribution System (WDS) is the station-wds mode. When a device is set to station-wds, it allows that device to connect to an access point (AP) while also enabling it to act as another AP for clients that want to connect. This dual functionality makes it possible for the device to rebroadcast the signal from the original AP, effectively extending the wireless network coverage.

In WDS setups, the station-wds mode is particularly crucial because it is designed for connecting multiple radio units to form a cohesive and expansive wireless network, supporting seamless roaming and transparent bridging for clients connecting through different devices in the WDS network.

Other options do not serve this purpose effectively. The ap-bridge mode is intended for access points connecting directly to clients, the nstreme-dual-slave mode is for use in environments utilizing Nstreme technology for wireless communications between two Nstreme devices where one acts as a master, and bridge mode typically functions at Layer 2 without the specific capabilities required for WDS. Thus, station-wds is the specifically designed mode for WDS configurations, allowing for appropriate network expansion and connectivity.
