Quick Answer

To fix the "Network Unclaimed" issue in Ubuntu 22.04.1, you need to install the necessary network drivers using the linux-modules-extra package. For USB port problems, updating your system to get any available driver updates can help.

Understanding the “Network Unclaimed” Issue

In Ubuntu, the “Network Unclaimed” issue typically arises when the system fails to recognize the network adapter due to missing drivers. This issue can be identified by running the command sudo lshw -c network. If your Ethernet controller and network controller are listed as “UNCLAIMED”, it means the system does not have the necessary drivers to use these devices.

Installing the Necessary Network Drivers

To resolve this issue, we need to install the necessary network drivers. The package that provides network drivers is linux-modules-extra. Follow the steps below:

  1. Identify your kernel version: Run the command uname -r in your terminal. This command will output the version of the kernel your system is running. For example, it might display something like 5.15.0-99-generic.
  2. Download the appropriate linux-modules-extra package: Visit the Ubuntu packages website and download the linux-modules-extra package that corresponds with your kernel version. For instance, if your kernel version is 5.15.0-99-generic, you would need the linux-modules-extra-5.15.0-99-generic package.
  3. Install the package: Transfer the downloaded package to your Ubuntu computer using a USB key or similar method. Open a terminal and navigate to the location where you saved the package using the cd command. For example, cd ~/Downloads. Install the package using the command sudo dpkg -i linux*.deb. This command installs the package on your system.
  4. Reboot your system: Finally, reboot your system with the command sudo reboot. After rebooting, check if your network devices are now working.

Fixing USB Port Problems

USB port problems can also be a result of missing drivers. To troubleshoot this, you can update your system to get any available driver updates. Follow these steps:

  1. Update your system: Run the command sudo apt update to update your package list. Then, run sudo apt upgrade to upgrade all the outdated packages. These commands ensure your system and its drivers are up-to-date.
  2. Check your USB devices: After updating, check if your USB devices are working. If not, you may need to install specific drivers for those devices.
