What I would like to achieve is two nodes using a wired backhaul. All DHCP, DNS, firewall, etc, handled by my opnsense router. I just want radio handoffs and the like between the mesh devices. Two other mesh units will use radio for the backhaul.
Looks like I have 802.11r and 802.11s working. Well, I really need to configure a second device to know for sure, but I’m caught in VLAN mess right now.
This video helped with the 802.11s: OpenWRT - 802.11s Mesh WiFi Network - YouTube and he has a further 802.11r video that is linked in the description. Not too difficult and the video is recent enough that the openWrt Luci interface matches. Note: I did update my access point to OpenWrt 22.03.2 r19803-9a599fee93.
