If you are running a Lenovo X1 Carbon notebook, chances are you may have some problems connecting to your wireless network. This issue could be due to outdated wireless driver software or a hardware problem.

In order to fix these problems, you should update the WLAN drivers. Luckily, there is an easy way to do this:

UEFI BIOS support

The UEFI BIOS supports a number of features. These include setting the date and time, reviewing hardware configuration information, setting wireless or hotkey functions, and changing the power-on startup process.

One of the best UEFI features is a firmware update that can be downloaded and installed from within the OS. Lenovo joined the Linux Vendor Firmware Service (LVFS) project in August 2018.

This enables BIOS updates and other firmware such as the Thunderbolt controller to be queried for and installed using the fwupd utility. This is the most efficient way to install a firmware upgrade since it doesn't require booting into the OS.

Another feature of the UEFI bios is a "whitelist" that prevents swapping out an LTE modem for one that is not supported by the BIOS. However, a way to evade this whitelist has been found.

LTE modems

A few laptops have built-in LTE modems that allow them to connect to mobile networks and access data. LTE is also known as 4G or Long Term Evolution, and it provides much faster data speeds than Wi-Fi.

If your laptop has built-in LTE, you can get an LTE data plan from your mobile carrier. This can be a great option for people who need to stay connected on the go.

Alternatively, you can use an external modem or hotspot to connect to an LTE network. These devices can provide high-speed wireless data to your laptop, but they are more expensive than LTE plans.

If you are using a Lenovo laptop that has an eSIM, you can activate an additional cellular data plan without having to remove or insert a physical SIM card. This is a great way to save on roaming charges when traveling abroad.

LVFS support

The Lenovo X1 Carbon wifi Driver for windows supports firmware updates via the Linux Vendor Firmware Service (LVFS). This is a web service that allows users to download metadata about available updates and optionally install them.

The LVFS is a web service that can be used by OEMs to upload firmware archives and by users to securely download metadata about available updates and optionally, the updates themselves. It also helps users understand what firmware updates are available on a device and how to install them, making it easier for consumers and end-users to stay updated.

It's a mature, critical part of the Linux ecosystem and is used by over one hundred vendors; 15 of those are multi-billion dollar companies. Richard Hughes, the project's founder, told me that his goal is to get 95% of updatable consumer hardware supported by the LVFS.

Cabinet files

Lenovo joined the Linux Vendor Firmware Service (LVFS) project in August of 2018. This allows BIOS updates and other firmware like the Thunderbolt controller to be queried for and installed through fwupd.

This is a great step forward for Lenovo. It means they are now able to provide deployment-ready driver packages that will allow you to automatically download, extract and import Lenovo drivers into your environment.

The tool does all of this from an XML feed provided by Lenovo’s site, reading this and performing some other bits in the background. It is available to download from here and can be used in MDT or SCCM.

Before installing these driver packs you should make sure your internet connection is stable and that you don’t have any firewall or antivirus software set up that is causing problems with the wifi drivers. You should also check that the drivers you have installed are correct and compatible with your computer model.
