After downgrading to 14 version,the L830-EB still work as before on both Win10 and Linux. I think it may be a problem about the hardware. Hope Lenovo can give some help.

Fibocom L850-GL not working in T480s

I bought a wwan card (Fibocom L850-GL). Installed it and was everything all right.

 

I ran System Update today, which found an update V.2.0.1.44, which I installed. System Update suggested me to restart my laptop. I did so an since than the following happens:

 

  1. System Update finds the very same update again and again. (And shows it in the history as installed update.)
  2. Cellular connection does not show up among available networks.
  3. No trace of the device in device manager, so I am not able to reinstall it or go back to an older version.
  4. Windows beeps sometimes, as if a new device was found, but nothing happens.

Any idea is wellcome! Thank you!

I have seen this happening as well. I have stopped installing the update for now. Hope Lenovo fixes soon, very annoying.
