WaveShare SIM7600 comes in several versions, including USB and HAT form factors. It’s known to work with Pi and Ubuntu.

Thanks - I will try the USB version: https://www.waveshare.com/sim7600g-h-4g-dongle.htm

If it does not help, I think you have to contact waveshare directly.

Hey all, I am having a issue with my raspberry setup. My Waveshare 4G HAT works fine, but sometimes it reconnects the USB interface. In the logs it says it disconnects and after 5 sec it connects again. Could this be a driver issue? How can I resolve this issue? OS: Raspbian Bullseye 64bit Software:...

The 'SIM7600' is just a generic name (based on the main chipset used). Do you have details of the actual board you are using, the version of Pi and its OS and how you have it set up (RNDIS / PPP etc)? Do you have anything plugged ...

Hey, I am using an original power supply for the raspberry, the SIM7600 is powered through the raspberry

bidrohini

Hello, what power supply are you using for the SIM7600? Power shortage can be one reason.

I got to the cause and found an axe, not solution.

The root cause is Modem Manager which comes with network manager, MM is known for grabbing ports randomly and I found no fix on that. It needs to grab port to work in the first place.

But I manage to disable it and 4G still works
