Windows 10 1903 - T470 Fibocom L831 no network traffic

2019-06-21, 13:58 PM

Just upgraded a T470 from B 1809 to 1903 and now the Fibocom L831 wwan card do not work/pass any traffic.

It is connected to my isp, gets a ip address and default gateway, but i cant ping either the assigned ip address or the gateway (of cause).

 

Tried resetting network card settings to default, remove wwan card and let windows find it again, newest driver installed 18.03.19 10.0.18362.1.

 

Any clue why Windows b1903 do not handle the mobile broadband nic correct?

Exactly the same problem appears on my T480. (Fibocom L830-EB)

 

I tried;

 

- Network reset

- reinstall driver (10.0.18362.1)

 

I am planning to clean install Windows 10 1903. But I don't believe this will fix the problem :(

I found my problem. It was caused by the Npcap lookback interface which i had to disable,
