EM7455 LTE Software broken Please help

2019-01-03, 13:52 PM

Lenovo Tablet 10 - Type 20L3


Serial Number: ###########
Machine Type Model: 20L3CTO1WW
Operating System
Windows 10 (64-bit)
Im entirely unsure which microsoft update has broken the LTE card. I last used it in december and only realize that it is broken now, after the holidays. The LTE says that it has service but can not connect. It gets an error about an APN. I tried to uninstall the device in device manager then reinstall it because it says that it is using a microsoft generic driver. This did not work. After installing the brand new drivers, the device switches to microsoft drivers. When I try to point to the drivers manually, it says that it is already using the best drivers. 
This is very upsetting as I am paying a monthly fee to use the wireless capabilities. PLEASE HELP!!!
Mod's Edit: Serial number removed from public view to protect member from its unwanted use.

Having the same issue, on an X1 Gen 6 with the newer Fibocom cellular card (L850-GL). Verizon service.

Constant APN issues, have to restart computer to get it to work. Been about a month. Very frustrating.

LTE worked fine on boot, but after sleep it connect, but No Internet.  Power off and and on would resolve the issue.  Sleep always broke it.

Lenovo replaced WWAN module and it has worked fine since for me.
