After the most recent update on Ubuntu 22.04, I’m experiencing a loss of network connectivity. Has anyone else encountered this issue and found a solution?

So, I’m hoping to tap into the collective wisdom of this community because I’ve hit a bit of a snag after the latest update on my Ubuntu 22.04. I’m not sure if it’s just me or if others have experienced this, but my network connectivity has gone completely haywire since I did the update. It’s like my internet just decided to take a vacation without me!

I usually keep my system up to date, and I’ve never run into issues like this before. Everything seemed fine during the update process itself—no errors or anything. But once I rebooted, I noticed that I couldn’t connect to my Wi-Fi, and when I tried using a wired connection, it didn’t show any network available. It’s driving me crazy because I rely on my computer for work, and I can’t afford to be offline for too long.

I’ve tried the usual troubleshooting steps, like restarting my router and checking if other devices can connect (they can, so that’s a relief). I also looked into the network settings on my system. Everything appears normal, but when I try to connect, it just keeps failing without giving me much information about what’s going on. I even dug into the terminal and ran some commands to check for errors or issues, but I’m not exactly a networking expert, and I’m not sure how to interpret all those lines of text.

Has anyone else here faced something similar? If so, did you find a fix that worked for you? I’ve done a bit of digging online, and it seems like I’m not alone in this issue, but the solutions I’ve come across are either too technical for me or just don’t seem to apply to my situation.

Any advice would be super appreciated! I really want to get my internet back up and running, and I’d be eternally grateful for any tips or tricks. Let me know if you need more information about my setup or the steps I’ve taken so far. Looking forward to hearing from you all!

    1. Ugh, I totally get how frustrating that must be! I’ve had my share of network troubles after updates too. It’s like the universe just decides you don’t need the internet anymore. 😩

      First off, it’s great you checked if other devices can connect! That’s always a good first step. Since you mentioned the usual troubleshooting (like restarting your router), here are a few more things you could try:

      • Check Network Manager: Sometimes, a simple restart of the Network Manager can help. You can do this by opening a terminal and running sudo systemctl restart NetworkManager.
      • Reinstall Network Drivers: Maybe the drivers got messed up during the update? You can try reinstalling them with sudo apt-get install --reinstall network-manager. Just be careful and make sure to check if your Wi-Fi card is recognized afterward!
      • Check Connection Settings: Open the network settings and look for your Wi-Fi connection. If it’s not listed, try adding it manually. If you have the option to forget the network and reconnect, that might help too.
      • Kernel Rollback: If all else fails and it’s really driving you up the wall, you can try booting with an older kernel. At the GRUB menu during startup, choose *Advanced Options* and select an older kernel version.

      If you can access your terminal, running ifconfig or ip a might show if your network interfaces are up and running.

      Honestly, don’t lose hope! There’s a good chance it’s just a small hiccup from the update. If you can share any specific error messages or what commands you’ve tried, maybe we can figure it out together!

    2. It sounds like you’re facing a frustrating issue with your network connectivity after the recent Ubuntu 22.04 update. Given that everything seemed fine during the update, it’s possible that the network driver or configuration has been affected. A common issue post-update can be related to drivers, especially if you’re using proprietary drivers for your network hardware. It would be worthwhile to check for any additional drivers required for your Wi-Fi and Ethernet connections. You can do this by going to “Software & Updates,” navigating to the “Additional Drivers” tab, and seeing if there’s an option to revert to a previous driver or update to a recommended one. If this doesn’t resolve your issue, consider running the command `dmesg | grep -i network` in the terminal, which can provide hints about any kernel or driver-related issues that may be happening during connection attempts.

      If checking the drivers doesn’t yield any results, you might want to reset your Network Manager configurations. Sometimes, configuration files can become corrupted during an update. To reset the Network Manager, you can open a terminal and run `sudo systemctl restart NetworkManager`. This will restart the network services and might help re-establish connectivity. Additionally, try deleting the existing network configurations by going to `/etc/NetworkManager/system-connections/` and removing any profiles related to your Wi-Fi or wired connections (be sure to back them up first). After doing so, reconnect to your network and see if the issues persist. If all else fails, consult the Ubuntu forums or community pages, as other users experiencing similar issues might have shared tailored solutions that suit your specific setup.
