I have the 5th gen Carbon X1 with integrated LTE / 4G modem. Sometimes when I wake my laptop, I cant connect to the mobile network unless I do a reboot to the machine. I get an error claiming no valid APN is set and I ned to set the APN.
Im not 100% sure in under what circumstanses it exactly happens at. I think at least if Im leaving home from ethernet via Thunderbolt 3 dock and I put the computer to sleep. When I wake up the machine and try to connect to the mobile network I get that message and cant connect. After reboot it connects and works fine.
There might be more situations when it happens too, but always reboot and it works. I have tried uninstalling the Sierra inf package, reinstal drivers etc, but doesnt seem to help. Also I have tried both options from bios on the automatically choose network when on ethernet (dont remember exactly what it is but anyway).
Everyone else has their integrated LTE working?
