The Mesh menu is absent because the current GL.iNet EasyMesh implementation requires the Mesh Main Router to operate in Router mode. Mesh nodes act as managed bridges/APs and can use Ethernet backhaul, but a Mesh Main Router operating in AP/bridge mode behind the Brume 3 is not currently supported. Flint 2 and Beryl AX received Mesh in the v4.11 firmware line, but your requested all-AP topology cannot use it. GL.iNet staff have confirmed that AP-mode Mesh is under discussion, with no committed version or ETA: Mesh Network in AP mode using firmware ver 4.11.
For your present topology, keep both devices in AP mode and configure:
- The same SSID, passphrase, and security mode on both APs.
- Fixed, different non-overlapping channels—use 20 MHz and channels 1, 6, or 11 on 2.4 GHz; select separate clean channels on 5 GHz.
- Similar channel widths on each AP and enough physical overlap for clients to discover the next AP, without excessive transmit power.
- WPA2-PSK/AES for maximum client compatibility, or identical WPA2/WPA3 settings on both if all clients support them.
This permits ordinary client-controlled roaming, although clients may remain attached to a weaker AP longer than desired. The official GL.iNet web interface does not independently expose 802.11r configuration. Manual 802.11r configuration through LuCI is not a supported configuration for this firmware/model combination, and its persistence through GL.iNet GUI changes or firmware upgrades is not guaranteed. This feature is not officially supported by GL.iNet. Any guidance is provided on a best-effort basis, and GL.iNet Technical Support may not be able to troubleshoot or maintain this configuration. If retaining the Brume 3 as the gateway is mandatory, the matched AP configuration above is currently the supported approach; otherwise, using one compatible Wi-Fi router as the Mesh Main Router in Router mode would be required for GL.iNet Mesh and wired backhaul.
