In this article, we will guide you through the process of installing the RZ608 MT7921K Wireless LAN driver on Ubuntu 18.04. This process involves updating the kernel, installing missing firmware, checking secure boot status, and clearing the CMOS state.
To install the RZ608 MT7921K Wireless LAN driver on Ubuntu 18.04, you need to update the kernel, install missing firmware, check Secure Boot status, and clear the CMOS state if necessary.
Updating the Kernel
The first step in this process is to update your kernel. The kernel is the core of your operating system and updating it can often resolve compatibility issues with hardware.
To update the kernel, you can use the following command:
sudo apt-get install --install-recommends linux-generic-hwe-18.04This command installs the latest Hardware Enablement (HWE) stack for Ubuntu 18.04, which includes the latest kernel.
After installing the new kernel, you should reboot your system for the changes to take effect:
sudo rebootInstalling Missing Firmware
Next, you need to ensure that all necessary firmware files for the MT7921K are present in the /lib/firmware/mediatek/ directory.
If the required firmware files are missing, you can download them from the manufacturer’s website and copy them to the appropriate directory using the cp command:
sudo cp /path/to/downloaded/firmware /lib/firmware/mediatek/This command copies the downloaded firmware file to the /lib/firmware/mediatek/ directory. Replace /path/to/downloaded/firmware with the actual path to the downloaded firmware file.
Checking Secure Boot Status
Secure Boot is a feature in UEFI that prevents the loading of unsigned kernel modules. If Secure Boot is enabled, it may prevent the MT7921K driver from loading.
To check if Secure Boot is enabled, you can use the following command:
mokutil --sb-stateThis command displays the current Secure Boot status. If Secure Boot is enabled, you should disable it in your UEFI settings.
Clearing the CMOS State
In some cases, clearing the CMOS state on your motherboard can resolve issues with the wireless adapter.
To clear the CMOS state, you need to short the necessary pins on your motherboard. The exact pins vary depending on the motherboard model, so you should refer to your motherboard manual for specific instructions.
Conclusion
By following these steps, you should be able to install the RZ608 MT7921K Wireless LAN driver on Ubuntu 18.04. However, remember that these are general suggestions and there may be other factors or specific configurations that could affect the compatibility of the driver with your system. Always refer to the documentation provided by your hardware manufacturer for the most accurate information.
The RZ608 MT7921K Wireless LAN driver is a software component that allows your Ubuntu 18.04 operating system to communicate with and utilize the wireless LAN capabilities of the RZ608 MT7921K wireless adapter.
Updating your kernel is important because it ensures that your operating system has the latest compatibility improvements and bug fixes for hardware devices. In this case, updating the kernel can help resolve any compatibility issues between Ubuntu 18.04 and the RZ608 MT7921K wireless adapter.
You can check your current kernel version by opening a terminal and running the following command: uname -r. This will display the kernel version installed on your system.
No, updating the kernel requires a system reboot for the changes to take effect. Make sure to save any unsaved work before initiating the reboot.
The missing firmware files for the MT7921K wireless adapter can typically be found on the manufacturer’s website. You can download them from there and then copy them to the /lib/firmware/mediatek/ directory on your Ubuntu 18.04 system.
The process of disabling Secure Boot varies depending on your computer’s motherboard and UEFI firmware. Typically, you can access the UEFI settings by pressing a specific key (such as F2 or Del) during the system startup. Look for the Secure Boot option in the UEFI settings and disable it.
Clearing the CMOS state is generally safe, but it should be done with caution. Make sure to follow the instructions provided in your motherboard manual and be careful when shorting the necessary pins. If you are unsure or uncomfortable performing this step, it is recommended to seek assistance from a knowledgeable individual.
