How can I resolve Wi-Fi connectivity issues on my MacBook Pro 2018 with an Intel chip running Ubuntu 22.04?

I’ve been struggling with my MacBook Pro 2018, which has that Intel chip, ever since I switched to Ubuntu 22.04. It’s supposed to be a great distro, but I’m having the most frustrating Wi-Fi connectivity issues. Sometimes it just won’t connect to my home network at all, and even when it does, the internet speed is painfully slow. I’ve tried a few basic fixes, like rebooting the router and toggling the Wi-Fi on my laptop, but nothing seems to be working.

I’ve also messed around with the Network settings in Ubuntu. I double-checked that the Wi-Fi is enabled, and I even deleted and re-added my home network a couple of times, thinking that might help. I’ve seen some posts about potential driver issues with Intel cards running on Linux, but I honestly don’t know where to start with that. It feels like I’m in way over my head!

I did some searching and saw people mention installing specific drivers or tweaking things in the terminal, but I’m not totally comfortable with that yet. I’m worried I might mess something up and make it worse. Could it also be an issue with power management settings? I read a few forums discussing how that could affect performance.

It’s frustrating because I do need to get some work done, and hopping onto my phone’s hotspot isn’t exactly a permanent solution. Then there’s the fact that my other devices connect to Wi-Fi without any issues—so it’s definitely an issue with my laptop. Have any of you run into this problem? What steps did you take to resolve it? Any help would be super appreciated! Detailed instructions would be fantastic since I’m kind of a beginner when it comes to Linux. Thanks in advance!

    1. It sounds like you’re dealing with a frustrating connectivity issue on your MacBook Pro running Ubuntu 22.04. First, it’s worth checking if your Intel Wi-Fi drivers are up to date, as outdated drivers can often lead to performance issues. Open a terminal and type sudo apt update followed by sudo apt upgrade to ensure your system is fully updated. Additionally, you can check for proprietary drivers by going to Software & Updates and navigating to the Additional Drivers tab. If there are any recommended drivers for your Wi-Fi card, you can enable them from there. Sometimes, installing the linux-firmware package helps, so you can do that by running sudo apt install linux-firmware in the terminal.

      Regarding power management settings, it’s possible that they are affecting your Wi-Fi connection. You can disable power management for your Wi-Fi card by creating or editing a configuration file. Open the terminal and type sudo nano /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf. Change the line wifi.powersave = 3 to wifi.powersave = 2 to disable power saving on Wi-Fi. After making this change, restart the Network Manager with sudo systemctl restart NetworkManager. This should enhance your Wi-Fi performance. If problems persist, consider exploring forums or documentation relating to your specific Intel Wi-Fi model for additional tweaks specific to your situation.



    2. Ubuntu Wi-Fi Issues on MacBook Pro


      Help with Wi-Fi Issues on Ubuntu 22.04

      Sounds like you’re having a rough time! It can really be a headache when things don’t just work out of the box on Linux, especially on a MacBook. Here are some ideas you can try to tackle those pesky Wi-Fi issues:

      1. Check for Updates

      First, make sure your system is up to date. Open the terminal (you can find it in your applications) and run:

      sudo apt update && sudo apt upgrade

      This will update your package list and install any available updates. Sometimes, new drivers or fixes come through updates.

      2. Install Intel Drivers

      Your Intel chip might need specific drivers to work better. You can try installing the linux-firmware package. In the terminal, type:

      sudo apt install linux-firmware

      After that, reboot your machine with:

      sudo reboot

      3. Disable Power Management

      Power management settings can sometimes throttle your Wi-Fi performance. To turn it off, you can edit the configuration file. Run:

      sudo nano /etc/modprobe.d/iwlwifi.conf

      If that file doesn’t exist, you can create it. Add the following line:

      options iwlwifi power_save=0

      Save the file (press CTRL + X, then Y, and hit Enter). Reboot afterwards!

      4. Check Your Wi-Fi Configuration

      Sometimes it’s good to double-check your Wi-Fi settings. Go to the Wi-Fi settings and ensure that your network is set to connect automatically and that you have the right password saved.

      5. Look for Kernel Issues

      If nothing seems to be working, you can try booting with an older kernel version. Sometimes the newest kernel might have issues with certain hardware. You can choose an older kernel from the GRUB menu when you start your computer.

      6. Recap and More Help

      If you’re still having problems, consider checking the Ubuntu forums or communities for Intel-specific issues. There’s a lot of knowledge out there!

      As you get more comfortable in Linux, don’t hesitate to explore and try new things. Just remember, you can always ask for help if you feel stuck. Good luck, and I hope you get your Wi-Fi sorted soon!
