I previously set up GL-MV1000W and GL-A1300 as a “LAN-only” access point, similar to the method described above by @David.
My procedure:
- Disconnect any Ethernet cable connected to the WAN port and any tethering/cellular device connected to the USB port.
- Connect to the router via wifi or Ethernet cable connected to the LAN port. Log into the GL.iNet Admin Panel and Disable any Repeater wifi that may have been set up previously. Alternatively, reset the router to start fresh.
- Log into the LuCI UI and go to Network → Interfaces → LAN → Edit. On the General Settings &Advanced Settings tabs, set Protocol to Static address, IPv4 address to a static IP on the main LAN subnet (e.g., 192.168.2.10), IPv4 gateway to the main LAN router (e.g., 192.168.2.1), DNS servers to the main LAN DNS servers (e.g., 1.1.1.1, 1.0.0.1). On the DHCP Server tab, Check/Enable Ignore interface to turn off the DHCP server. Save and Apply the settings, then the router will reboot.
- After the router has rebooted, plug in an Ethernet cable from the main router LAN port to the GL.iNet router LAN port (no connection on the WAN port).
- Connect to the router at its static IP address (e.g., 192.168.2.10) via wifi, Ethernet cable connected to the LAN port, or through your main LAN router.
- Log into the LuCI UI and go to System → Startup to Disable and Stop mwan3 from running.
The GL.iNet router will then be connected on your main LAN only, on the same subnet, accessible by wifi or Ethernet. The LED on the router may keep flashing that there is no Internet on the WAN and, if this is bothersome, you can cover it with black tape. Alternatively, turn off the LED by DIsabling/Stopping gl_led from running in LuCI and editing /etc/config/gl_led to set led_enable and led_daemon to ‘0’.
I do not work for and I do not have formal association with GL.iNet
