Summary

This guide helps you troubleshoot and resolve: How to fix Mac Wi-Fi that keeps dropping or won't connect. Follow the steps below to fix the issue.

Common Causes

Wi-Fi connectivity issues on a Mac can range from occasional dropouts to a complete inability to connect. This guide walks you through troubleshooting steps for modern macOS versions, including Ventura, Sonoma, and Sequoia.

Quick Fix Steps

Before diving into detailed troubleshooting, try these common fixes first. They resolve the majority of Wi-Fi issues on macOS.

1. Toggle your Wi-Fi off and on by clicking the Wi-Fi icon in the menu bar and selecting Turn Wi-Fi Off, waiting ten seconds, then turning it back on.
2. Restart your Mac by clicking the Apple menu → Restart.
3. Restart your router by unplugging it from power for 30 seconds, then plugging it back in. Wait two minutes for it to fully boot.
4. Check for macOS updates by going to System Settings → General → Software Update.

Detailed Instructions

Forget and Rejoin the Wi-Fi Network

Sometimes your Mac holds onto outdated network settings or a corrupted password. Forgetting the network forces it to start fresh.

1. Click the Apple menu → System Settings.
2. Select Wi-Fi from the left-hand sidebar.
3. Find your network under Known Networks and click the More (three dots) icon next to it.
4. Select Forget This Network and confirm.
5. Click the Wi-Fi icon in the menu bar, select your network, and re-enter your password.

Renew Your DHCP Lease

Renewing the DHCP lease can resolve IP address conflicts that frequently cause dropouts.

1. Open System Settings → Wi-Fi.
2. Click Details… next to your connected network.
3. Switch to the TCP/IP tab.
4. Click Renew DHCP Lease and confirm.
5. Click OK to apply the changes.

Change DNS Servers

Switching to a public DNS server can improve connection reliability if your ISP's DNS servers are slow or unreliable.

1. In System Settings → Wi-Fi, click Details… next to your network.
2. Select the DNS tab.
3. Click the + button under DNS Servers and enter 8.8.8.8.
4. Click + again and add 8.8.4.4 (Google DNS) or 1.1.1.1 (Cloudflare DNS).
5. Click OK to save.

Check for Third-Party Software Interference

Third-party VPN clients, firewall applications, or security software can interfere with Wi-Fi connectivity. If you have recently installed any network-related software, try temporarily disabling or uninstalling it to test whether the connection stabilises.

Wi-Fi Icon Missing or Wi-Fi Will Not Turn On

If the Wi-Fi icon is missing from the menu bar or Wi-Fi will not turn on at all, try the following:

1. Open System Settings → Control Centre.
2. Scroll to the Wi-Fi section and ensure Show in Menu Bar is set to Always or Show in Menu Bar.
3. If Wi-Fi still will not turn on, go to System Settings → Wi-Fi and ensure the Wi-Fi toggle is switched on.
4. Restart your Mac and check whether Wi-Fi becomes available.
5. If the issue persists, check for macOS updates at System Settings → General → Software Update.

Troubleshooting

Delete Wi-Fi Configuration Files

If the above steps haven't resolved the issue, corrupted preference files may be the culprit. Deleting these forces macOS to rebuild them.

1. Turn off Wi-Fi by clicking the Wi-Fi icon in the menu bar and selecting Turn Wi-Fi Off.
2. Open Finder and press Shift + Command + G to open the "Go to Folder" window.
3. Enter the following path: /Library/Preferences/SystemConfiguration/
4. Locate the following files and move them to your Desktop as a backup:
   • com.apple.network.eapolclient.configuration.plist
   • com.apple.wifi.message-tracer.plist
   • NetworkInterfaces.plist
   • preferences.plist
5. Restart your Mac. macOS will recreate these files automatically.
6. Turn Wi-Fi back on and reconnect to your network.

Check for Interference

Physical obstacles and other wireless devices can interfere with your Wi-Fi signal. If your Mac connects fine in one location but drops out in another, interference is likely the cause.

• Keep your router away from microwaves, cordless phones, and Bluetooth devices.
• Minimise walls and metal objects between your Mac and the router.
• Try switching your router to the 5GHz band if your Mac supports it, as it is less prone to interference than 2.4GHz.
• Check if other devices in your vicinity experience the same dropouts to determine whether the issue is with your Mac or the router.

Run Wireless Diagnostics

macOS includes a built-in diagnostic tool that can automatically detect and sometimes fix Wi-Fi problems.

1. Open System Settings → Network → Wi-Fi.
2. Click Details… next to your connected network.
3. Click Open Wireless Diagnostics….
4. Follow the on-screen prompts to allow the tool to analyse your connection.
5. Review the summary report for any identified issues and recommended fixes.

Reset NVRAM (Intel-based Macs Only)

Non-volatile random-access memory (NVRAM) stores certain settings that macOS can access quickly. Resetting NVRAM can resolve persistent hardware-related connectivity issues on Intel-based Macs. Apple Silicon Macs (M1, M2, M3, and later) do not have a user-resettable NVRAM or SMC, so these steps do not apply.

1. Shut down your Mac completely.
2. Press the power button, then immediately hold Option + Command + P + R.
3. Continue holding the keys until your Mac restarts and you hear the startup sound play a second time, or until the Apple logo appears and disappears a second time.
4. Release the keys and allow your Mac to finish starting up.

Business Wi-Fi Environments

If you are connecting to a business or enterprise network, additional factors may apply:

• Enterprise networks using WPA2-Enterprise or WPA3-Enterprise may require a username and password or a digital certificate rather than a simple pre-shared key.
• Captive portals (common in offices, hotels, and shared workspaces) require you to open a web browser and accept terms or log in before full internet access is granted.
• If your Mac connects to the network but cannot reach the internet, try opening a website to trigger the captive portal login page.
• Contact your IT administrator if you suspect certificate issues, MAC address filtering, or network access restrictions.
