Hi,
I am using a Quectel UC20-G that fails to work reliably once the system has booted.
After every 5th or 6th startup, the modem will have one of the following errors (from the Windows Cellular setting):
- No service
- Disconnected - if the cellular setting has this error and you try to conenct manually - you get error message “Can’t connect to this network. Enter an APN and try again”
- The modem is installed in a Giada F210 PC running Win10 Enterprise LTSC.
- The windows Cellular setting is set to auto connect
- The APN setting is correct
- I am using the UC20 drivers from the Quectel website: V 5.0.1.1
- Revision is UC20GQDR03A19E1G
- IMEI is 860147042675072
I have tested a couple of different SIM cards but the results are the same. After 5-6 reboots, the cellular setting will show this error and only a reboot can fix it. This is a problem as these are supposed to be unattended IoT devices.
I also tested an older UC20EC using the same hardware (PC, SIM, OS, etc). The older card does not have this issue, even after 20+ restarts, cold starts, and power cycling at the wall socket. .
Is there a newer driver/firmware available for this modem?
kind regards
Peter
