In this article, we will guide you through the process of troubleshooting and resolving the issue of a USB WiFi adapter not being recognized in Ubuntu 22.04. This is a common problem experienced by many Ubuntu users, but with the right steps, you can easily get your USB WiFi adapter up and running.
Understanding the Issue
When you plug in your USB WiFi adapter, Ubuntu 22.04 should automatically detect and use it. However, there are instances where it doesn’t recognize the adapter, which could be due to various reasons such as incompatible drivers, hardware issues, or even a faulty USB port.
Checking the USB WiFi Adapter
The first step in troubleshooting is to check whether Ubuntu is detecting your USB WiFi adapter. You can do this by running the lsusb command in the terminal. This command lists all USB devices connected to your system.
lsusbIf your USB WiFi adapter is listed, it indicates that Ubuntu is detecting your device at a hardware level. If it’s not listed, try plugging it into a different USB port or check it on another computer to rule out a hardware issue.
Identifying the Chipset
The next step is to identify the chipset of your USB WiFi adapter. This is important because the chipset determines the driver that your device needs to function correctly. You can find this information from the manufacturer’s website or the product documentation. For instance, if you are using the AWU650 adapter, it uses the Realtek RTL8821AU chipset.
Installing the Driver
Once you’ve identified the chipset, you need to install the appropriate driver. Most manufacturers provide Linux drivers for their devices. You can download the driver from the manufacturer’s website and extract the ZIP file. Inside the extracted folder, you should find an installation script, typically named install.sh.
Change your current directory to the extracted folder using the cd command:
cd /path/to/extracted/folderThen, run the installation script:
sudo ./install.shThe sudo command is used to run the script with root privileges, which is necessary for installing drivers. The ./ before the script name is used to specify that the script is in the current directory.
Using a USB WiFi Adapter with Built-in Linux Kernel Support
If the manufacturer-provided driver does not work or is not available, consider using a USB WiFi adapter that has built-in support for the Linux kernel. These adapters work out-of-the-box without the need for additional drivers. You can find a list of such adapters on various Linux forums and websites.
Keeping Up-to-Date with Driver Compatibility
It’s important to note that not all USB WiFi adapters are compatible with Linux, and even if they are initially compatible, future updates to the Linux kernel may break their functionality. Therefore, it’s crucial to stay informed about driver compatibility. You can refer to resources like the Ubuntu Hardware Compatibility List and various Linux forums for this information.
