LTE 4g cards Fibocom 850-gl WWAN FRu 01AX792 do not work on thinkpad L15 amd ryzen

2021-01-21, 10:11 AM

I have a L15 amd 20U8S0AH00 which is wwan ready, ie there a 2 antennas. I bought 2 fibocom 850gl to get the LTE feature but they get disconnected and connected all the time on windows 10. This is on windows 1809, 2004, 20h2 and 21h1. I hear the chime sound every two minutes.

On various  clean installs, I tried to install the drivers with lenovo system update, with lenovo vantage and with windows update directly. Nothing works.

The cards are FRU 01AX792, which is what is required for the thinkpad L15 has seen here https://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-l-series-laptops/thinkpad-l15-type-20u7-20u8/20u7/20u70004ge/parts/display/model

 

I tried with and without a working SIM card in the slot.

 

Please provide a way to update the firmware of those cards once and for all.

 

There is a famous problem with those cards

https://forums.lenovo.com/t5/ThinkPad-X-Series-Laptops/Fibocom-850-GL-WWAN-does-not-install-seem-to-exist/td-p/4509271

 

Here is the problem under USBlogView

 

I get Lenovo Vantage to install the drivers, but after reboot the drivers is again required...

 

 

 

 

In device manager, I don't even get

0.9.4.399          (ModemControl)
3.19041.2019.1    (Fibocom GNSS Sensor)
18500.5903.0025.1  (FirmwareUpdateDriver)

 

all i see is Intel(R) XMM7360-P WWAN

 

 

 

 

here are pictures of the cards

Hello OKlee,

 

 


Greetings

 

 

 

Please uninstall the current WWAN driver.  Click the box to completely remove it from the system, and then manually install the current version available from the support site.

 

 

 

 

Update us how it goes.


Regards, 
Lorenzo_Lenovo

yes i tried the manual install with r17wj07w.exe from https://pcsupport.lenovo.com/fr/fr/products/laptops-and-netbooks/thinkpad-l-series-laptops/thinkpad-l15-type-20u7-20u8/20u8/20u8s0ah00/pf20nzc4/downloads/driver-list/component?name=Réseau %3A Sans fil WAN

 

I choose ''install' as the option and it produces the same effect: nothing is installed and the chime sounds keeps going. THis was done with both the SIM and without the SIM card.

 

I also tried the manual install with extract, then click Setup.bat in  C:\DRIVERS\WAN\20212101.18593412 and still the same failure
