Fix Wi-Fi Not Working on Mac in macOS 14 Sonoma
This guide will show you different troubleshooting methods to fix your Wi-Fi when it’s not working on your Mac.
1. Check if You’re on the Right Wi-Fi Network
If you’ve multiple Wi-Fi networks saved on your Mac, your Mac might skip the one you want to connect to and connect to an unexpected one. As a result, you might see an exclamation mark on the Wi-Fi icon, and you’ll receive a notification that says you don’t have internet access. To verify you’re on the correct Wi-Fi network, select the Wi-Fi icon in the menu bar and see if the Wi-Fi network’s name is what you wanted.
There may be times when you see Wi-Fi networks with the same name, and as you get confused, Mac will too. In such situations, connect to both and visit any website in your web browser to check if it works. If not, connect to a different one and repeat the same. Once you find the Wi-Fi network you’ve been looking for, forget the Wi-Fi network you don’t want.
2. Remove and Reconnect to the Wi-Fi Network
If you’re still facing this issue, it’s best to remove the Wi-Fi network from your saved list and then connect to it again, as it may reset it to its usual settings. Here are the steps to remove and reconnect to any Wi-Fi network:
1. Click on the Apple menu () and select System Settings.
2. Select Wi-Fi from the left sidebar.
3. Scroll down on the right side, and click Advanced.
4. Select the three-dot menu in the new dialog box to the right of the Wi-Fi network you want to connect.
5. Click the Remove From List option from the dropdown menu.
6. Close the dialog box and toggle off your Wi-Fi.
7. Wait a few minutes and turn on your Wi-Fi again.
8. Select the Join option from the Other Networks section on the Wi-Fi you want to connect. Enter the password if prompted and click Join.
Once done, your Wi-Fi should work as usual, and if not, proceed with the following troubleshooting methods in this guide.
3. Run Wireless Diagnostics
If you still can’t figure out the issue, your next best solution is to run the Wireless Diagnostics app on your Mac. It’s a tool developed by Apple to detect problems with your wireless connections.
You can access it by searching for Wireless Diagnostic in Spotlight search or Launchpad, followed by the Return key. Otherwise, you can hold the Option (⌥) key on your keyboard, click the Wi-Fi icon, and select the Open Wireless Diagnostics option from the list.
Once opened, follow the instructions (mostly clicking the Continue button) and the Wireless Diagnostics will run and determine the error with your Wi-Fi network. If it finds any issues, it’ll guide you through the required troubleshooting methods to fix them. As a result, you will get a good idea of the issue.
4. Make Sure You’re in the Wi-Fi Network’s Range
You get better signals and internet speeds near your Wi-Fi router. But as soon as you go far away, the Wi-Fi signal starts to drop, and if you go far enough, it’ll completely disconnect.
There are also times when you’re close to the Wi-Fi router, and you still don’t get the Wi-Fi signal. It may be due to walls between your Mac and the router or some problem with your Wi-Fi router if there’s no obstacle between you and the object.
It’s good to ensure that you’re in your Wi-Fi network’s range before you conclude anything further.
5. Restart Your Router
If you find that your router is having some issues, the first thing to do is to restart your router. You can do that by unplugging the power adapter from the power outlet and waiting 10 minutes before you plug it back in.
However, if you have a power button on the wireless router, you can simply press it to turn it off and wait 10 minutes before you can push it again to turn it back on.
6. Renew DHCP Lease
You can only use this troubleshooting method if you can connect to your Wi-Fi network. Nevertheless, as complex as it sounds, DHCP (Dynamic Host Configuration Protocol) lease is a part of TCP/IP settings that can get your Wi-Fi network running again when renewed. Follow these simple instructions to learn how to renew the DHCP lease on your Mac:
1. Open System Settings from the Apple menu ().
2. Select Wi-Fi from the sidebar.
3. Click the Details option next to your connected Wi-Fi network.
4. Select TCP/IP from the new window and click the Renew DHCP Lease option.
5. Choose the Apply option when you receive a confirmation prompt.
6. Click OK at the bottom, and you’re ready.
Try opening a website from your web browser on the Mac, and see if your internet is working again or not. If not, move forward with the following troubleshooting methods.
7. Check DNS Settings
Every ISP provider has a default DNS, and when it’s not working, you’ll run into Wi-Fi issues on the Mac. In such cases, you can use an alternate public DNS provider like Google or Cloudflare to see if it solves your problem. Follow these steps to know how you can change your DNS on Mac:
1. Open the Apple menu () and select System Settings.
2. Click Wi-Fi from the sidebar and then Details next to your connected Wi-Fi network.
3. Select DNS on the left side of the new window.
4. Click the Plus (+) button, type 220.127.116.11 or 18.104.22.168, and press the Return key on your keyboard.
Check if your internet is working again; if it isn’t still, proceed with the following methods.
8. Make Sure You’re Not Connected to a VPN
Sometimes, willingly or unwillingly, we leave a VPN turned on and forget about it. VPNs are good for masking your IP address. But since they must reroute your internet every time you send a packet of data, your internet speed can slow down when more data accumulates.
To fix this, check if a VPN is running in the background. If you can’t find any VPN app in the Dock or the menu bar, you can find it through the System Settings on macOS. Go to System Settings and select VPN from the sidebar. If you see any toggle turned on next to the listed VPN apps, turn it off.
9. Update to the Latest macOS
If nothing mentioned above works for you, it could be a bug with macOS. If you’re on a Developer or Public beta, you should wait for the next update and hope Apple will fix the bug. Hence, installing the latest updates on your Mac is best, where Apple fixes most bugs. Here’s how to check for the latest updates on macOS:
1. Open the Apple menu () and select System Settings.
2. Go to General, followed by Software Update.
3. Click the Update Now after you receive an update. Your Mac will restart once the update finishes.
Once your Mac restarts, try connecting to your Wi-Fi again and verify if Wi-Fi is working or not. If not, there aren’t many troubleshooting methods, so try the following last resorts.
10. Contact Your ISP
Sometimes it might not be your Mac, but your ISP (Internet Service Provider) having an issue at their backend. There can be various reasons why the ISP can’t provide you with the internet. A maintenance break could happen or some problem with the cables that provide internet or something else.
Hence it’s best to contact them and discover the problem with your Wi-Fi network. They’ll visit your home and troubleshoot the problem with your Wi-Fi network, router, and your Mac before they can conclude anything.
11. Contact Apple Support
Suppose your internet provider visited you and ensured everything is alright from their end and the router; it’s probably a hardware issue with your Mac. If that’s the case, you must visit your nearest Apple Support, where they’ll take your Mac, diagnose the problem, and fix it. The process may take 3-5 days, and they won’t charge you a fee if your Mac is under warranty or the Apple Care+ plan.
These were some of the best ways to fix the Wi-Fi not working on your Mac. We hope you resolved the issue through this guide. Again, if Apple Support can’t fix the problem, they’ll replace the Mac for you if it’s under warranty or the Apple Care+ plan.
