MC7710 unable to reconnect to 3G or LTE from 2G



after the start of AirCard Watcher I connect to the LTE Network but when the signal falls down to 2G, the Modem is unable to automatically change to 3G or LTE.

If the signal strength falls from LTE to 3G it can go back up to LTE without any problems.

I have tested it on 3 Laptops with the same issue.

Please help.

Firmware: Generic LTE
Driverversion: 12.9.1005.15

Best Regards



Is there any active data session goin on ?


Yes but just 2G, it is unable to switch back to 3G and LTE
