Setup WDS2
WDS2 (Wireless Distributed System 2) links up access points to create a
wider network in which mobile users can roam while still staying
connected to available network resources. The wireless client and root
access point has to be set up with the same channel frequency. This
allows them to connect even when the link is lost, as the channel
frequency setting is preserved.
In this example, there are 2 access points: Access Point 1 and Access
Point 2, with Access Point 1 as the root access point.
