Connect to the Internet via cellular

The router can be used to access the Internet through cellular. There are two cases, some models have a built-in 3G/4G model; some models have a usb port and can be plugged into a usb 3G/4G modem. The operation steps are similar, here is GL-AXT1800 as an example.

On the left side of web Admin Panel -> INTERNET, Cellular sector.

Note: Some SIM cards may need to be activated the first time you use them, so please activate them in your phone before using them in your router.

  1. We recommend to turn off the router first, insert your SIM card into the USB modem then plug the USB modem into the USB port of the router, and then turn it on again. If you insert a usb modem at power on, the page may be no change, please refresh the page.

  2. Please access the web Admin Panel -> INTERNET, Cellular sector. The first time, it may not connect automatically, but it has read the name of your carrier in the upper left corner and the IMEI, then please click Auto Setup.

    Please ignore the warning of Incompatible Modem

  3. Connecting.

    Note: Some SIM cards may have special usage restrictions, such as the need to use a special APN. If your SIM card can't be registered, please consult your network operator if it has special restrictions.

  4. After a while, it will be connected. Otherwise, try Manual Setup.

    When the usb modem is plugged into the router the second time it is powered on, it is usually automatically recognized and a connection is established. It may not get the information of signal, modem name and IMEI.

When Internet access is not available, the corresponding warning is displayed. To determine whether you can access the Internet or not, please go to Multi-WAN page.
