Asked: 2024-09-26T23:47:03+05:30 In:

I recently installed Ubuntu 23.04, and I’ve encountered an issue where my WiFi adapter is not recognized. It was functioning properly just yesterday. Can anyone provide guidance on how to resolve this problem?

I really need some help here. I just installed Ubuntu 23.04 a couple of days ago, and everything was going smoothly until I woke up this morning to find that my WiFi adapter is not recognized anymore. It was working just fine yesterday! I’m not sure what happened overnight, but it’s quite frustrating.

I’ve tried a bunch of the usual troubleshooting steps—rebooting the system, toggling the WiFi switch on my laptop, and even playing around with the network settings a bit. When I go into the Settings to check for WiFi, it just shows “No WiFi Adapter Found,” which is making me feel pretty stuck. I really don’t want to have to connect to the internet via an Ethernet cable all the time.

I’ve done some research online, but the solutions I found seem a bit over my head. I saw some people suggesting that I might need to update or reinstall network drivers, but I’ve never really done that before, and I’m worried I might mess things up even more.

Has this happened to anyone else? I’d love any tips or suggestions you might have. Should I be checking out any specific drivers? Is there a command or tool in the terminal that could help me see if the adapter is even being detected at all?

Also, if you’re thinking about suggesting anything related to kernel updates or configurations, could you please break it down for someone who’s not super tech-savvy? I’m just trying to get back to being able to connect without hassle.

It’s kind of absurd how much we rely on WiFi these days, and now I feel like I’ve taken a step back without it. Any help or advice would be so appreciated! Please let me know if you need any more details from my end, like my hardware specs or any error messages. Thanks a ton!

    1. WiFi Adapter Issue in Ubuntu 23.04

      WiFi Adapter Isn’t Recognized

      Sounds like you’re in a frustrating spot! Here are a few things you can try to get that WiFi adapter back up and running:

      1. Check if the Adapter is Detected

      Open up the terminal (you can find it in the applications menu) and run this command:

      lspci | grep -i network

      This should list your network devices. If you don’t see your WiFi adapter listed here, it might be a hardware or driver issue.

      2. Reload the WiFi Driver

      You might be able to reload the driver for your WiFi. Try this command in the terminal:

      sudo modprobe -r

      Replace with the actual name of your WiFi driver if you can find it in the output from the previous command. Then reload it:

      sudo modprobe

      3. Update Your System

      Sometimes, simply updating your system can fix the issue. Run:

      sudo apt update && sudo apt upgrade

      4. Check Additional Drivers

      In the settings, you can look for “Software & Updates” and then click on the “Additional Drivers” tab. Sometimes, proprietary drivers for your WiFi card might be available there.

      5. Restart Network Manager

      Another thing to try is restarting the Network Manager with:

      sudo systemctl restart NetworkManager

      6. Kernel Issues

      If you’re feeling adventurous, maybe check your kernel version with:

      uname -r

      If there’s a known issue with your kernel and WiFi, you might consider downgrading or upgrading the kernel, but that can get a bit technical.

      7. Last Resort

      If nothing seems to work, and you are really stuck, you might want to seek help on forums like Ask Ubuntu or the official Ubuntu forums. Usually, people are quite helpful, just provide them with your laptop model and any error messages you see.

      You’re definitely not alone in this, and I’m sure you’ll get back online soon! Good luck!



    2. It sounds frustrating that your WiFi adapter is not being recognized after a period of working perfectly. First, let’s check if your system is detecting the WiFi hardware. Open a terminal and run the command lspci | grep -i network. This command lists all PCI devices and filters out the network-related ones, helping you identify if your WiFi adapter is even recognized by Ubuntu. If your adapter doesn’t show up in this list, it could be a hardware issue, but if it does, you’ll want to check if the drivers are correctly installed. Running sudo lshw -C network can provide more detailed information about your network devices and their driver status.

      If your adapter is recognized but not functioning, you may need to install or update the drivers. You can do this by using the command sudo apt update && sudo apt install --reinstall , where corresponds to the driver for your specific WiFi hardware. To find out the specific driver needed, you can visit Ubuntu forums or search for your WiFi adapter’s model to see which driver is recommended. Finally, be cautious with kernel updates; if you need to update the kernel, it’s best to follow guides that detail the process step by step, allowing you to revert changes if something goes wrong. With careful steps, you should be able to restore your WiFi connectivity without needing to wire up your laptop!
