I’m encountering an issue with my Wi-Fi connections on Ubuntu where I receive an error message stating that the activation of the network connection has failed. This problem occurs for all my Wi-Fi networks. Can anyone provide guidance on how to troubleshoot and resolve this issue?

I’ve been having this really frustrating issue with my Ubuntu setup lately, and I’m hoping someone here might have the magic answer. So, here’s the thing: whenever I try to connect to any Wi-Fi network—doesn’t matter if it’s my home network or a coffee shop’s—I’m hit with this annoying error message that says, “activation of the network connection has failed.” Like, seriously? Why can’t I just hop on the internet like everyone else?

I thought maybe it was just a quirk with a specific network, but nope! This happens with every single Wi-Fi connection I try to make. I’ve rebooted my laptop more times than I can count, and even reset my router, thinking that might fix something. But no luck. I’m really starting to feel like my poor laptop is cursed or something!

To add to the mystery, my Ethernet connection works just fine. So, it’s definitely a Wi-Fi issue—maybe a driver problem? I’ve looked into updating drivers, but I’m not super tech-savvy, and the whole process feels like a maze of confusion.

I’ve played around with the network settings a bit, disabling and re-enabling Wi-Fi, but nothing seems to work. I’m almost convinced that I’m missing some simple step that’s blocking my way to getting connected. Is there some hidden setting I should be checking? Or maybe there’s a command I can run in the terminal that could shed some light on this problem?

If anyone has been through something similar or has dealt with network connections in Ubuntu, I’d really appreciate your advice! I’d love to avoid doing a full reinstall of the OS, but at this point, I’m getting desperate. Any tips, tricks, or even just some comfort that I’m not the only one who’s faced this would be awesome! Thanks in advance for your help!

    1. Ubuntu Wi-Fi Issue Help


      Sounds like you’re having a tough time! That “activation of the network connection has failed” message can be super annoying. Here are a few things you can try:

      1. Check Wi-Fi Driver

      Since the Ethernet works fine, it might indeed be related to the Wi-Fi drivers. You can check the current drivers and see if there’s anything that needs updating. Open a terminal (Ctrl + Alt + T) and run:

      lspci -nnk | grep -iA2 net

      This will show you the network devices and their drivers.

      2. Update Your System

      Maybe check if your system is up-to-date because updates can sometimes fix bugs. In the terminal, run:

      sudo apt update && sudo apt upgrade

      You might need to reboot after this.

      3. Reset Network Manager

      You can try restarting the Network Manager service. Run:

      sudo systemctl restart NetworkManager

      Then see if that helps.

      4. Forget and Reconnect to Networks

      In your network settings, you can try removing any saved Wi-Fi networks and then reconnecting. Sometimes old settings can create issues.

      5. Check for Blocked Devices

      Sometimes network devices get blocked. You can check this by running:

      rfkill list

      If it says “blocked,” you can unblock it with:

      sudo rfkill unblock all

      Then try connecting again.

      6. Check Logs for Errors

      If you’re still stuck, checking the logs might give you more info. You can do this by running:

      journalctl -xe | grep NetworkManager

      Look for clues in the output.

      Hopefully, one of these fixes works! You’re not alone in this struggle—it can be tricky at times. Good luck!


    2. It sounds like you’re dealing with a frustrating Wi-Fi connectivity issue on your Ubuntu setup. Given that your Ethernet connection is functioning well, it’s likely that the problem is isolated to your Wi-Fi configuration, potentially involving drivers or network settings. First, I would recommend checking for any proprietary drivers that may need to be installed for your Wi-Fi card. You can do this by opening the “Software & Updates” application, navigating to the “Additional Drivers” tab, and seeing if any driver options are available for your wireless network adapter. If a proprietary driver is listed, try selecting it and applying the changes. After that, perform a system reboot and see if the issue persists.

      If that doesn’t solve the problem, it’s worth resetting your network settings to rule out any misconfiguration. You can run the following commands in the terminal: sudo service network-manager restart to restart the Network Manager service, and nmcli networking off followed by nmcli networking on to toggle network management. Additionally, try checking the status of your Wi-Fi with iwconfig — it should display a list of network interfaces and their statuses. If the command shows that your Wi-Fi interface is disabled, you might need to enable it with sudo ifconfig wlan0 up, replacing ‘wlan0’ with your actual Wi-Fi interface name. Should these steps not resolve the issue, reviewing log files like /var/log/syslog may provide more specific error messages related to the Wi-Fi connection attempts and help identify other underlying causes.
