After I upgraded my modem to a SIM7600 (and replaced my SIM card) I hoped the GSM would be running well again.
I'm sorry to say that I still have issues. Every few days GSM will disconnect with "Last Error: User Interrupt". When it disconnects this way it won't connect anymore. Not even when I change location. Only after a "module reset" the connection comes back for another few days.
The antenna I use is the internal antenna of the car. I had no issues like this last year. Same antenna then.
Am I alone with this behauviour?
Any ideas?
Thanx
Chris
