PSA : do not update Fibocom L850-GL WWAN Driver to version 2.0.1.91 (nz3wj27w)

2020-06-30, 8:24 AM

Hi.


Lenovo Vantage recently updated the Fibocom L850-GL WWAN Driver to version 2.0.1.91 (nz3wj27w) on my X1 Carbon 6th.

Since the update, I have noticed the version of the driver have a bug and uses a lot of CPU (System/Interrupt) (module UDE.sys).

 

Disabling the Intel(R) XMM7360-P WWAN device in Device Manager solves the problem.

If you don't use the WWAN feature, disable the device in Device Manager or in BIOS.
If you use WWAN, try a previous driver version.
