Jetson Nano with waveshare 7600G - LTE stops working after ~1hour

I am using the Jetson Nano B01 with the waveshare 7600G LTE module which connects via GPIO and USB (Port 2).

the module works out of the box. However the LTE drops after 1 to 4 hours (most times after 1 hour). I contacted the waveshare support and was told to change the PID switch:

from: AT+CUSBPIDSWITCH=9001,1,1

to: AT+CUSBPIDSWITCH=9011,1,1

according to this link (Raspberry Pi networked via RNDIS - Waveshare Wiki)
via:

sudo minicom -D /dev/ttyUSB2

There are also some tutorials on how to install the LTE module via command line (e.g. GitHub - phillipdavidstearns/simcom_wwan-setup: A guide and files for setting up the Waveshare SIM7600G-H Hat for Jetson Nano)

but nothing resolves the problem of the dropping LTE …

I have tried multiple SIM cards from multiple providers (in Japan: Softbank,bmobile) … nothing works …

Sorry for the late response, that might be issue on hat LTE module, and we can’t support it further.
