1. Update the Kernel

The first step in troubleshooting this issue is to update the kernel. The kernel is the core component of the operating system and it directly interacts with the hardware. By updating the kernel, you may be able to resolve compatibility issues with the Wi-Fi adapter.

To update the kernel, open the terminal and run the following commands:

sudo apt update
sudo apt upgrade

The sudo command allows you to run commands with administrative privileges. The apt update command updates the package list on your system, and the apt upgrade command upgrades all outdated packages.

After running these commands, reboot your system and check if the Wi-Fi adapter is detected.

2. Install the Firmware

If updating the kernel doesn’t solve the issue, you may need to install the firmware for the Intel Wi-Fi 6 AX200 adapter. The firmware is a piece of software that provides low-level control over the hardware.

You can download the firmware file from the official Intel website or the Linux wireless wiki. Once you have downloaded the firmware file, copy it to the /lib/firmware directory by running the following command:

sudo cp /path/to/firmware/file /lib/firmware

Replace /path/to/firmware/file with the actual path to the downloaded firmware file.

3. Check for Conflicting Drivers

Conflicting drivers can prevent the Wi-Fi adapter from being recognized. To check if any conflicting drivers are loaded, run the following command:

lsmod | grep iwlwifi

The lsmod command lists all loaded kernel modules, and the grep command searches for the specified pattern, in this case, ‘iwlwifi’. If any conflicting drivers are listed, unload them using the rmmod command followed by the driver name.

4. Check for Hardware Switch

Some laptops have a physical switch or a key combination to enable/disable the Wi-Fi adapter. Ensure that this switch is in the ‘on’ position. If you are unsure about the location or operation of this switch, refer to your laptop’s user manual.

5. Check for BIOS Settings

Lastly, access your computer’s BIOS settings and ensure that the Wi-Fi adapter is enabled. BIOS settings can vary greatly depending on the manufacturer, so refer to your motherboard or computer manual for specific instructions.

If none of the above solutions work, it is possible that the Wi-Fi adapter is not fully compatible with Ubuntu 20.04. In such cases, you may need to consider using an external Wi-Fi adapter that is known to be compatible with Linux.

Remember, it’s always a good practice to backup your important data before making any changes to your system. Troubleshooting hardware issues can be complex, but with patience and the right information, you can resolve them.

We hope this guide has been helpful in resolving your Wi-Fi adapter issues on Ubuntu 20.04. If you have any questions or suggestions, feel free to leave a comment below.

What is a kernel?

The kernel is the core component of the operating system. It is responsible for managing the system’s resources, such as memory, processes, and hardware devices. It acts as a bridge between the hardware and software, allowing applications to communicate with the hardware.

How do I update the kernel in Ubuntu 20.04?

To update the kernel in Ubuntu 20.04, you can use the apt package manager. Open the terminal and run the following commands:

sudo apt update
sudo apt upgrade

The apt update command updates the package list on your system, and the apt upgrade command upgrades all outdated packages, including the kernel. After running these commands, reboot your system to apply the updates.

What is firmware?

Firmware is a type of software that provides low-level control over the hardware. It is stored on a hardware device, such as a Wi-Fi adapter, and is responsible for initializing and controlling the device. Installing the firmware for a specific device can help resolve compatibility issues and improve its functionality.

How do I unload conflicting drivers?

To unload conflicting drivers, you can use the rmmod command followed by the driver name. For example, if the conflicting driver is named "driver_name", run the following command:

sudo rmmod driver_name

This will unload the driver from the kernel. You can then check if the Wi-Fi adapter is detected.

How do I access the BIOS settings?

To access the BIOS settings, you need to restart your computer and press a specific key during the startup process. The key to access the BIOS settings can vary depending on the manufacturer. Common keys include F2, Del, Esc, or F12. Consult your computer’s user manual or look for on-screen prompts during startup to determine the correct key to press. Once in the BIOS settings, navigate to the section related to hardware or devices and ensure that the Wi-Fi adapter is enabled.
