X250 issues with Sierra EM7345 after Windows Fall creators update 1709

After installing Windows Fall creators update 1709 my Sierra EM7345 almost doesn't work. When I establish the connection everything works fine, but only for 15-30 seconds, then connection goes away. Ping 8.8.8.8 starts throwing error: General failure. 

I tried installing newest driver from lenovo support, but situation hasn't changed. Driver properties screenshot attached.

It seems Abdesamad has found a workaround to the issue. Disabling unneeded network adapters in control panel solves the issues. I've had a few VPN adapters, Abdesamad had VM NICs that should be disabled. I guess NICs with static IPs interfere with cellular modem interface somehow.

Same issue with the P50 adn EM7455 when using external usb ethernet adapters with a fixed ip address (internal lan is on dhcp). Any hints how to use the cellular internet connection and keep any adapter with a static ip address enabled?

 

Thanx!

Not really.  I have DISABLED and UNINSTALLED the Sierra Wireless adapter in Device Manager but somehow Windows keeps turning it back on which eventually leads to a BLUE SCREEN citing wmbclass.sys as the problem.
