X1C7 Windows 10 and Fibocom L850-GL - anybody got it working?

2019-09-14, 20:19 PM

I am receiving an error when I try to connect to the cellular network with my X1C7:

 

"Can't connect to this network. Enter an APN and try again"

 

I have tested this SIM card in T420 and it can connect successfully. Win 10 is updated to the latest, all drivers too, but still no success.

 

Output from the cmd shows that the SIM card is recognized and registered on the network, but still no successful connections:

 

One thing I did notice is that my driver is "generic mobile broadband adapter" released by Microsoft and no matter what I try to install the Lenovo one - removing, choosing manual update, it still stubbornly chooses the generic one.

Any chance you found a fix for this?

The only resolution we found was to disable selective suspend and uncheck the box to allow windows to turn off the device to save power but when we do this it causes WUDFHost crashes when coming out of hibernation.

I did - by using a different carrier.

 

I tried their sim card and it worked without a flaw. To this day I don't know what was the issue with old guys (that same account worked on my old T420)

Glad to hear you found a resolution. We've tried a couple different carriers but no luck. Lenovo continues to blame Microsoft. 

 

Thanks for the quick reply!
