X1 Carbon 5gen + Sierra EM7455 problem

2021-04-05, 10:25 AM

Hello

 

I've bought OEM Lenovo LTE modem FRU01AX748 (part sourceв from a notebook xxxxx).

Installed both modem and antennas. On errors, drivers are ok. I am in Russia.

System says it has connected to LTE network and have access to the internet. But in fact internet doesn't work.

But if I turn on NordVPN application, internet access works. 

No problems with access via WiFi or LAN without VPN. 

It doesn't depends on GSM operator.  

 

Please advice.

Hello atas,

 


Greetings

 

How was it when connecting with different machines? 
How about connections on different configurations?
Can you share the machine type model / MTM (ex. 81C70000RK) from the sticker as it would help us detail more about your machine variant.

I don't know how this modem worked on the original machine. My machine is 20HRS04C00 but after Motherboard failure I've got i7-16Gb instead of stock I5-8Gb. Plus SSD replaced with compatible 512Mb drive. What do you by "connection on different configurations"?

Sorry, I am not sure of your current motherboard, and from what original machine it came so we cannot confirm compatibility of the WLAN card on it and its whitelisting.

If feature is not originally offered then we can't guarantee that it would work.
Lets wait for the comments of fellow users who might have the same set up working.
