If Wi-Fi is not working on your Mac, start by checking whether the problem affects only the Mac or every device on your network. Then restart Wi-Fi, reconnect to the network, and restart your router. If your Mac connects but websites do not load, check VPN settings and DNS. For persistent problems, use Wireless Diagnostics to identify possible signal, configuration, or hardware issues.
Quick Answer
Try these steps in order:
- Make sure Wi-Fi is turned on and Airplane Mode is not affecting your connection.
- Check whether other devices can access the internet.
- Turn Wi-Fi off and back on, then restart your Mac.
- Forget the Wi-Fi network and join it again.
- Temporarily disconnect your VPN and check DNS settings.
- Restart your router and modem.
- Use Wireless Diagnostics if the problem continues.
Before changing network settings, save your work. Some troubleshooting steps disconnect the internet, close connections, or require you to enter your Wi-Fi password again.
Check Whether the Problem Is Your Mac or the Network
First, determine how widespread the problem is. Try connecting a phone, tablet, or another computer to the same Wi-Fi network.
- Only your Mac has a problem: The issue may involve your Mac’s Wi-Fi settings, VPN, DNS, software, or wireless hardware.
- Several devices cannot connect: The router, modem, internet service, or Wi-Fi provider may be responsible.
- Your Mac connects but has no internet: The Wi-Fi connection may be working, but the router, DNS, VPN, or internet service may not be.
Also check whether the problem affects every website or only one. Open a few unrelated sites in your browser. If only one website fails, the issue may be with that site rather than your Mac or Wi-Fi network.
Turn Wi-Fi Off and Back On
A quick Wi-Fi reset can resolve temporary connection problems.
- Select the Wi-Fi icon in the menu bar.
- Turn Wi-Fi off.
- Wait about 10 seconds.
- Turn Wi-Fi back on.
- Select your network and enter its password if prompted.
If you do not see the Wi-Fi icon, open Control Center from the menu bar and select Wi-Fi.
You can also use System Settings:
- Open the Apple menu and choose System Settings.
- Select Wi-Fi.
- Turn Wi-Fi off, wait briefly, and turn it on again.
Check Your Wi-Fi Network and Password
Your Mac may be connected to a different network, a guest network, or a network with a weak signal.
- Open System Settings.
- Select Wi-Fi.
- Confirm that the correct network appears under the connected network.
- If necessary, select Details next to the network to review its settings.
Move closer to the router if the signal is weak. Thick walls, floors, large appliances, metal objects, and long distances can reduce wireless performance.
If macOS repeatedly rejects your password, confirm that:
- Caps Lock is off.
- You are using the correct network password.
- You are connecting to the correct Wi-Fi network.
- The router’s password has not recently changed.
Restart Your Mac
Restarting can clear temporary network and system problems.
- Save your work.
- Close open apps if possible.
- Open the Apple menu.
- Select Restart.
- After your Mac starts, select the Wi-Fi icon and reconnect.
If an app prevents the restart, avoid forcing it to close unless necessary. Force-closing an app can cause unsaved work to be lost.
Forget the Wi-Fi Network and Join Again
Forgetting a network removes its saved connection information from your Mac. This can fix corrupted or outdated Wi-Fi settings, but you will need to enter the password again.
Forget a Current or Nearby Network
- Open the Apple menu and select System Settings.
- Select Wi-Fi.
- Find the network under known or nearby networks.
- Select Details next to the network.
- Choose Forget This Network or Forget This Network…, depending on the macOS interface.
- Confirm the action.
- Return to the Wi-Fi list.
- Select the network and enter its password.
If you are currently connected to the network, forgetting it will disconnect your Mac immediately. Save online work first.
If you do not see the network in the list, select Advanced in Wi-Fi settings and review the saved networks. Remove the affected network if it is listed there, then connect again.
Restart Your Router and Modem
If multiple devices have no internet access, restart the network equipment.
- Save work that depends on an internet connection.
- Unplug the router’s power cable.
- If you have a separate modem or gateway, unplug it as well.
- Wait at least 30 seconds.
- Plug in the modem or gateway first.
- Wait several minutes for its status lights to stabilize.
- Plug in the router.
- Wait for the router to finish starting.
- Reconnect your Mac to Wi-Fi.
Do not press the router’s Reset button unless you intend to restore factory settings. A factory reset can erase the Wi-Fi name, password, and other custom configuration.
If the router has separate 2.4 GHz and 5 GHz networks, try both. The 2.4 GHz band may work better at a distance, while 5 GHz can offer higher speeds nearby. Some routers automatically combine these bands under one network name.
Check for VPN Interference
A VPN, or virtual private network, routes internet traffic through another server. This can improve privacy or provide access to a work network, but a damaged profile or temporary VPN outage can cause a Mac to appear connected without internet access.
To test whether a VPN is responsible:
- Open the VPN app.
- Disconnect from the VPN.
- Try several websites.
- If the internet works normally, reconnect the VPN and check its settings or update the app.
You can also review VPN configurations in macOS:
- Open System Settings.
- Select VPN.
- Turn off or remove a configuration only if you recognize it and no longer need it.
Warning: Removing a work, school, or organization-managed VPN may prevent access to internal resources. If the VPN belongs to your employer or school, contact its administrator before deleting the configuration.
Other network-filtering apps, security tools, parental-control software, and antivirus products can also interfere with connections. Temporarily pause a third-party network feature only long enough to test the connection, then turn it back on.
Check DNS Settings
DNS, or Domain Name System, translates website names such as example.com into numerical internet addresses. If DNS is not responding, Wi-Fi may show as connected while websites fail to load.
Review DNS Settings
- Open System Settings.
- Select Wi-Fi.
- Select Details next to the connected network.
- Select DNS.
- Review the listed DNS servers.
- Select Cancel if you only wanted to inspect the settings.
If your organization, internet provider, or router requires specific DNS servers, do not remove them without checking first.
Add a Public DNS Server for Testing
You can test whether your current DNS service is the problem by adding a reputable public DNS server.
- Open System Settings.
- Select Wi-Fi.
- Select Details next to the connected network.
- Select DNS.
- Select the + button under DNS Servers.
- Enter a DNS server address supplied by a trusted provider.
- Select OK, then Apply if macOS displays that button.
- Test several websites.
Adding a DNS server changes how your Mac looks up website addresses. It does not repair a failed internet connection, router, or Wi-Fi signal.
To reverse the change, return to System Settings > Wi-Fi > Details > DNS, select the added server, choose the – button, and apply the change. If the DNS server was supplied by your organization or network administrator, restore the original settings instead.
Renew the DHCP Lease
DHCP automatically gives your Mac an IP address, which is its address on the local network. A bad or expired address can prevent internet access.
- Open System Settings.
- Select Wi-Fi.
- Select Details next to the connected network.
- Select TCP/IP.
- Select Renew DHCP Lease.
- Select OK.
Your connection may briefly stop while macOS requests a new network address. This step does not erase your files or Wi-Fi password.
Use Wireless Diagnostics
macOS includes Wireless Diagnostics, a tool that can examine Wi-Fi conditions and create diagnostic information. It does not automatically repair every problem, but it can reveal signal, channel, or connection issues.
- Hold the Option key on your keyboard.
- Select the Wi-Fi icon in the menu bar.
- Choose Open Wireless Diagnostics.
- Follow the on-screen instructions.
- When the initial check finishes, review the recommendations.
Wireless Diagnostics may ask for information about your network and may create diagnostic files. These files can be useful to an IT professional or Apple Support representative. Avoid changing advanced wireless settings unless you understand the effect.
You can also hold the Option key while selecting the Wi-Fi icon to view additional connection details, such as signal information, channel, and connection rate. The exact information shown can vary by Mac and macOS version.
Test in Another Location or With a Different Network
Connect your Mac to a different Wi-Fi network, such as a phone’s personal hotspot or a trusted network elsewhere.
- Your Mac works on another network: The original router, password, DNS, or network configuration is likely responsible.
- Your Mac fails on every network: The problem may involve macOS, a VPN or security app, or the Mac’s wireless hardware.
If you use a personal hotspot for testing, remember that it may consume cellular data quickly.
Install Available macOS Updates
Updates can include fixes for system and networking problems.
- Open the Apple menu.
- Select System Settings.
- Select General.
- Select Software Update.
- Install available updates if appropriate.
Save your work before installing an update. Your Mac may restart, and the installation can take time. If your Mac cannot access the internet, use another connection temporarily or download updates when a reliable network is available.
Troubleshooting Common Mac Wi-Fi Problems
Mac says it is connected, but there is no internet
Check whether other devices can browse the web. If they also fail, restart the modem and router. If only your Mac is affected, renew the DHCP lease, disconnect the VPN, and test DNS settings.
Wi-Fi keeps disconnecting
Move closer to the router and test whether the problem occurs in one location or everywhere. Restart the router, forget the network, and join it again. Wireless Diagnostics can help identify weak signal or interference.
The Wi-Fi network does not appear
Make sure Wi-Fi is turned on and that the router is broadcasting its network. Move closer to the router and restart it. If the network is hidden, choose the option to join another network and enter its network name and password manually.
The Mac connects slowly
Check the signal strength and test near the router. Other devices, nearby networks, Bluetooth accessories, walls, and appliances can contribute to interference. Restart both the Mac and router, then compare performance on another network.
Only one website or app does not work
Try another browser or website. If other sites work, the problem may be specific to the website, app, account, or its server. Check the app for updates and temporarily disable browser extensions if the issue occurs only in a browser.
Wi-Fi works in Safe Mode but not during normal startup
A login item, VPN, security tool, or network-filtering app may be interfering. Review System Settings > General > Login Items and temporarily disable unfamiliar network-related items. Do not remove software you need for work or school without confirming its purpose.
Nothing fixes the problem
Contact your internet provider if multiple devices cannot connect. Contact the network administrator for work or school networks. If your Mac cannot connect to any Wi-Fi network and other devices work normally, Apple Support or an authorized service provider can help determine whether hardware service is needed.
Frequently Asked Questions
Why does my Mac say “Wi-Fi connected” but have no internet?
Wi-Fi connectivity only means your Mac can communicate with the router. The router may not have internet access, or DNS, DHCP, a VPN, or the internet service itself may be failing.
Should I reset my Mac’s network settings?
macOS does not provide one universal “reset network settings” button. Start with less disruptive steps such as forgetting the network, renewing the DHCP lease, checking DNS, and disconnecting the VPN. More extensive manual changes can remove custom settings and affect work or school connections.
Will forgetting a Wi-Fi network delete my files?
No. Forgetting a network removes its saved Wi-Fi connection information, including the saved password. It does not delete personal files or applications.
Can a VPN cause Wi-Fi problems?
Yes. A VPN can block or reroute traffic when its connection, configuration, or software is not working correctly. Disconnect it temporarily to test whether normal internet access returns.
How do I know if the router is the problem?
If phones, tablets, and other computers also cannot access the internet, the router, modem, or internet service is likely involved. Restart the equipment and contact your internet provider if the problem remains.
When should I contact Apple Support?
Contact Apple Support if your Mac cannot connect to any Wi-Fi network, Wireless Diagnostics reports a serious issue, or the problem continues after testing another network and disabling third-party network software.
Final Thoughts
When Wi-Fi fails on a Mac, identify whether the issue affects one device or the entire network first. Reconnecting to Wi-Fi, restarting the router, forgetting the network, renewing DHCP, checking DNS, and disconnecting a VPN resolve many common problems. If the Mac still cannot connect anywhere, Wireless Diagnostics and professional support can help identify a deeper software or hardware issue.
