Convexa B1300 4G usb modem question


I have a GL-B1300(Convexa-B) setup as my router.

I want to use the 4G modem option. Internet - GL.iNet Docs

I am considering buying or something like this.

However, I am not sure how to determine whether this dongle will work with the Convexa-B. I know there is a compatible modem list: Internet - GL.iNet Docs This page links to ROOter by Of Modems and Men which states:

Support is available for modems that use the USB port, the PCie interface and the M.2 interface.

Does anyone know whether the 4G modem will work with the Convexa-B or how I find out?


Please note that the AliExpress device is only an adapter and does NOT include the actual 4G LTE module, which is more expensive. You have to buy one of the the Compatible Modems listed on the GL.iNet page (e.g., Quectel EC25-E, EC25-A, EC25-V, EC25-C) that plugs inside the adapter.

If you decide to proceed, here are some caveats:

  1. Different 4G LTE modules work only with different mobile carriers and countries/regions
  2. The 2 main interfaces are M.2 Key B and mini PCIe, with mini PCIe seeming to be more common (e.g., Quectel EC25-A), but the AliExpress device is M.2 Key B and will not accept mini PCIe
  3. I recently tried 3 different similar products from Amazon for my Sierra Wireless M.2 Key B module, but none of them worked and I returned all of them.

I do not work for and I do not have formal association with GL.iNet

Ah thanks @wcs2228 that explanation really helped. I’ll try to find out what LTE modules will work with my carrier. Cheers.

Hello, I was able to use my EM160R-GL with a box similar to the one you posted, it’s slightly larger to support 4 antennas (so that every RF connector is correctly addressed on the EM160R-GL, remember to never power up anything without every antenna connected)

I’ve flashed ROOter and for the list of supported modems you need to refer to them, not GLiNet since ROOter handles the establisment of the MBIM connection over USB and other AT commands to know modem’s status such as signal quality, temperature, APN settings, temperature etc.

Here’s a picture:

and a speedtest…
