X1 Carbon 3rd Gen mobile broadband stopped working

I try to keep that short:

 

symptons:

- i see my mobile broadband network in tray, i can connect it. it shows fine, no error, looks like connected perfectly.

- on Diagnose the Mobile NUmber shows cryptic signs, and i get the error:

the mobile broadband adapter is sim-pin2 locked. (hope translation is fine, my installation is german: "Das mobile Breitbandgerät ist durch eine SIM-PIN2 gesperrt."

 

- i cannot browse anywhere, i cant ping, i cannot even ping own IP and Gateway.

- Hardware: Sierra Wireless EM7345 4G LTE

- Driver: 10.0.16299.192

- Firmware FIH7160_V1.2_WW_01.1616.01

- GPRS; EDGE; UMTS,HSDPA;HSUPA;LTE;HSPA+

 


This started 2 days ago, 5th February 2018, after i installed new Windows 10 Updates (Windows 10 , 1709 (Build 16299.192)

 

i tried:

- remove SIM card,

- replaced SIM card with a new one

- uninstalled driver, reinstalled

- deleted and reconfigure APN

 

... Still all looks fine, as it would be perfectly connected, but cannot ping/reach anything.

 

Any ideas? Thank you!

Welcome to the Community

The modem' fw version seems the recent.
Are the drivers installed from x1c gen3 download page?

Change the APN value from Auto to your cellular operator's (tariff plan, contract etc.) one:
Settings > Network & Internet > Cellular > Advanced options > Add an APN.

Even if in the future the Auto value will return back, PIN 2 request should not appear.
