Quectel EM060K-GL not working with Beryl AC1300

Hello you,

i have tried to figure out a way to equip my Beryl AC1300 with LTE connectivity.

I found the following in the docs: Cellular - GL.iNet Router Docs 4

And decided to buy the one modem i could find online, the Quectel EM060K-GL.
Amazon-Link: Amazon.de

I put the modem into a carier board from Waveshare: https://amzn.eu/d/cR5BWj7

The lights are activated and if i plug the carier board into my PC it shows up and i immediatly have LTE connectivity.

Unfortunately this isn´t the case for my Beryl AC1300.
If i plug the carier board into the router it doesnt detect it:

I stumbeled upon some posts which had a similar or identical problem, but i can´t figure out what to do.

Thank you in advance :smiley:

After upgrading, everything just works.
