When a wired Ethernet backhaul link is used to attach a Wi‑Fi System Extender to a Wi‑Fi System Controller, setting up custom Wi‑Fi channels on the Extender is now possible. Setting non-overlapping Wi‑Fi channels on different Wi‑Fi System nodes will maximize wireless clients' performance. If a wired Ethernet backhaul link disconnects, the Extender will automatically switch to a Mesh wireless backhaul link to resume operation. In this case, depending on the Mesh wireless backhaul interface, the corresponding Wi‑Fi channel on the Extender will follow the backhaul link. Once a wired Ethernet backhaul link is restored, the Extender will automatically use wired backhaul and preset Wi‑Fi channels. [NDM-1801]
