For those interested in small dual band routers, we have recently posted test SECN firmware for the GL-iNet AR750M dual band device.
It can support various combinations of AP and Mesh connections across the 2GHz and 5GHz bands, and so it may be suitable for simple mesh networks eg where it is desirable to run the mesh network on a separate band to the APs as a backbone network.
The 5G (1T1R, 20dBm) radio has a uFL antenna connector on the board, so it is possible connect an external antenna.
The 2G (2T2R, 23dBm) radio has two antennas built in to the main PCB and can operate in MIMO mode.
SECN Firmware
-----------------------
The default SECN firmware configuration runs an Access Point on 2GHz and a Mesh on 5GHz, bridged on the LAN network side, as for other SECN devices.
A Mesh WAN mode configuration is also available, so you can set up for example a 5GHz mesh backbone network for nodes that provide local individual AP networks on 2GHz for wifi client access.
Mesh and Access Points can be configured to operated on either or both 2GHz and 5GHz radios.
The test firmware is available here:
SECN-VT-RACHEL Firmware
------------------------------------------
The default SECN-VT-RACHEL firmware runs as a simple router with an Access Point on 2GHz with the Ethernet WAN port active.
The default configuration also runs a "Public" (guest) Access Point which allows access to the library content but not the WAN.
A "WAN Mesh" mode is available, and this configuration runs a Mesh on 5GHz, bridged on the WAN side of the router.
This configuration allows automatic sharing of an upstream network connection (eg to an Internet modem/router) between multiple devices.
If the Ethernet WAN port of one device is connected to the Internet, then the connection will be shared to all other devices via the 5G mesh.
This can be used as a simple way to provide classroom routers serving digital library content, and sharing an Internet connection.
The test firmware is available here:
If you are interested in using this device, please test and report any issues.
