Ho to Fix macOS Sequoia WiFi issues

Having trouble with Wi-Fi issues on macOS Sequoia? This guide provides clear, step-by-step solutions to get your Mac back online smoothly and reliably.

Check Your Basic Network Settings

Before diving into advanced fixes, confirm that your Wi-Fi is turned on and you are connected to the correct network.

  • Go to Apple menu > System Settings > Network.
  • Ensure Wi-Fi is enabled.
  • Verify you’re connected to the right network and review details for any warning signs like incorrect IP configuration or security issues.

This quick check may uncover simple configuration errors that cause connection problems[2].

Toggle Wi-Fi Off and On

This simple but effective step can fix many temporary glitches.

  • Click the Wi-Fi icon in the menu bar.
  • Turn Wi-Fi off and wait 10-15 seconds.
  • Turn Wi-Fi back on and reconnect to your network.

This refreshes your network connection and can clear momentary bugs.

Restart Your Mac

A system reboot clears cache, refreshes network hardware, and resolves many minor software glitches.

  • Click the Apple menu and select Restart.
  • Once restarted, try connecting to Wi-Fi again.

Many users report instant improvements after restart[1][3].

Forget and Re-add Your Wi-Fi Network

Removing your current Wi-Fi network and reconnecting can clear corrupt settings specific to that network.

  • Navigate to Apple menu > System Settings > Wi-Fi.
  • Click Details (next to your network) and select Forget This Network.
  • Reconnect by selecting the network from Wi-Fi options and entering the password.

This often resolves persistent connection or authentication issues.

Flush the DNS Cache

A corrupted DNS cache can prevent proper website loading and network stability.


  • Open Terminal (Applications > Utilities).



  • Enter the command:


    sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder


  • Press Return, enter your admin password when prompted.



  • Restart your Mac afterward.

Flushing DNS clears stale cached data and can restore connectivity.

Change Your DNS Servers

Using reliable DNS servers like Google (8.8.8.8 and 8.8.4.4) or Cloudflare (1.1.1.1) can enhance network performance and resolve loading problems.

  • Go to System Settings > Network > Wi-Fi > Details > DNS.
  • Replace existing DNS addresses with preferred DNS servers.
  • Save and reconnect.

This can speed up connections and bypass ISP DNS issues.

Reset Network Preferences

Especially if Wi-Fi randomly disconnects or drops, resetting your Mac’s network preferences can help:


  • Turn off Wi-Fi.



  • In Finder, use Go > Go To Folder and enter:
    /Library/Preferences/SystemConfiguration/


  • Move these files to your desktop as a backup:

    • com.apple.airport.preferences.plist
    • com.apple.network.eapolclient.configuration.plist
    • com.apple.wifi.message-tracer.plist
    • NetworkInterfaces.plist
    • preferences.plist

  • Restart your Mac.



  • Turn Wi-Fi on and reconnect.


This method deletes potentially corrupted network configurations and forces macOS to recreate them cleanly[4].

Disable “Limit IP Address Tracking”

A known macOS Sequoia bug can cause unstable Wi-Fi due to the Limit IP Address Tracking feature.

  • Go to System Settings > Network > Wi-Fi > Details.
  • Find Limit IP Address Tracking and turn it off.

Many users have found this restores stable connections without any further changes[7].

Use Wireless Diagnostics

macOS includes a built-in tool to identify Wi-Fi problems.

  • Hold the Option key and click the Wi-Fi icon.
  • Select Open Wireless Diagnostics.
  • Follow the on-screen instructions to diagnose and attempt automated fixes[5].

Restart Your Router

Sometimes, the issue may not be your Mac but your router or modem.

  • Unplug your router’s power cable.
  • Wait 30 seconds.
  • Plug it back in and wait a couple of minutes for it to reboot.
  • Test your Mac’s Wi-Fi connection again.
