After upgrading to Ubuntu 24.04 LTS, my Wi-Fi connection has stopped functioning. I am looking for solutions to resolve this issue. Has anyone encountered a similar problem and found a way to fix it?

So, I finally decided to upgrade to Ubuntu 24.04 LTS because I’ve heard so many great things about it, but now I’ve hit a major snag—my Wi-Fi connection has completely stopped working! I mean, how frustrating is that? I was hoping for some cool new features and enhancements, but instead, I’m stuck in this digital limbo where the internet is just out of reach.

I’ve tried a couple of things already, like restarting my laptop and toggling the Wi-Fi switch (you know, the old “turn it off and on again” trick). I also updated my drivers thinking maybe that would do the trick. But nope, nothing. The Wi-Fi icon just shows that it’s searching and then gives up on life, which is super annoying. When I check the settings, it doesn’t even recognize my home network anymore. It’s like my laptop has decided to go on a Wi-Fi detox!

I’ve browsed through a couple of forums and found some people mentioning similar issues after upgrading, but the suggestions were all over the place. Some said it could be a kernel problem, while others pointed to missing firmware. I’m not exactly a tech whiz, so I feel a bit overwhelmed trying to figure out where to start. I thought about rolling back to the previous version, but that feels like taking a huge step backward instead of embracing the latest release.

Has anyone out there gone through the same situation? I could really use some help or at least a bit of guidance on what to try next. I’ve seen other people mentioning using the terminal for some commands, but I’m honestly a bit intimidated. If you’ve managed to fix your Wi-Fi issue after upgrading or know of a straightforward solution, please share your wisdom! It would mean a lot to me right now, and who knows, maybe I can pay it forward once I’m back online!

    1. Upgrading to Ubuntu 24.04 LTS can sometimes lead to unforeseen issues, particularly with hardware support like Wi-Fi connections. Given your description, it sounds like the upgrade might have altered some settings or created a mismatch with your network drivers. A common step to troubleshoot this is to check if your Wi-Fi card is correctly recognized by the system. You can do this by opening the terminal (press Ctrl + Alt + T) and executing the command lspci | grep -i net. This will display a list of recognized network devices. If your Wi-Fi card is listed, it confirms that the system recognizes the hardware. Also, verify that the network manager service is running using the command sudo systemctl status NetworkManager—this might provide clues if there are related issues.

      If you find that the driver is causing issues, you could try reinstalling or switching to a different driver version. Use the command sudo apt update && sudo apt install --reinstall network-manager to reinstall the network manager. If that doesn’t help, you might consider checking for proprietary drivers under “Software & Updates” > “Additional Drivers.” Sometimes, third-party drivers are more reliable for Wi-Fi hardware. If you’re intimidated by terminal commands, I recommend following step-by-step guides available on forums like Ask Ubuntu or the official Ubuntu documentation. They often have user-friendly tutorials that can make the process less daunting. Remember, you’re not alone in this; many users have faced similar challenges, and the community is typically very supportive.

    2. It sounds like you’re in a bit of a bind with your Wi-Fi after upgrading to Ubuntu 24.04 LTS! That’s definitely frustrating, especially when you were looking forward to trying out the new features.

      First off, since you’ve already tried the basics like restarting and toggling the Wi-Fi, here are a few things you might want to consider:

      • Check for Additional Drivers: Sometimes, the Wi-Fi drivers aren’t automatically installed. Go to Settings > Additional Drivers. See if there are any proprietary drivers available for your Wi-Fi card that can be activated.
      • Reinstalling Network Manager: If you’re feeling up to it, you can try reinstalling Network Manager. Open the terminal (don’t worry, you got this!) by pressing Ctrl + Alt + T and run the following commands:

        sudo apt update
sudo apt install --reinstall network-manager
      • Check Kernel Version: Since some folks mentioned kernel issues, you can check your kernel version in the terminal with:

        uname -r

        If you find that the kernel version is indeed causing trouble, you might want to try booting into an older kernel from the GRUB menu when starting up your computer.

      • Firmware Issue: Sometimes, missing firmware can cause Wi-Fi issues. You can look for a package called linux-firmware. You can install or update it using:

        sudo apt install linux-firmware

      After making any of these changes, make sure to restart your computer to see if your Wi-Fi comes back to life!

      Don’t hesitate to look up tutorials or guides on these commands if you’re unsure—they can really help ease the intimidation factor. If all else fails, rolling back is always an option later, but hopefully, one of these steps will do the trick!

      Good luck, and feel free to ask if you have more questions as you troubleshoot!
