Why is my Mac connected to WiFi but no internet?

Most of us treat WiFi the same as the internet, even if Wi-Fi is simply a tool connecting you to a local network that directs you to the internet. That's to say that having Wi-Fi-connected doesn't guarantee you internet access, though it usually does. The problem mainly lies in your router, the network provider, and Mac.

If your Mac won't connect to internet but other devices will, your Mac is most likely the culprit.

If other devices can't connect to the internet as well, there's something wrong with the router or internet service provider.

If you can't access the internet with a Hotspot from your mobile data, the internet service provider or your Mac is causing trouble.

If your Mac can connect to the internet via other WiFi networks, there's a problem with your router.

Specifically, the reasons for Mac connecting to Wi-Fi but no internet are as follows:

  • Corrupted preferences file
  • Troublesome Profiles
  • Operating system bugs
  • Expired DHCP lease
  • Wrong date, time, or location
  • Faulty router settings
  • Software blocking internet
  • Outdated router firmware

It's hard to find the reason why your Mac won't connect to WiFi but phone will without trying anything. Nevertheless, you'll likely find a working fix below regardless of the cause.

Create a new network location

Usually, your Mac sets the network location automatically for you. However, if your Mac is connected to WiFi but no internet, you need to create a new one.

    preferences.plist           
    Settings.plist

 Note: You may not have all the preferences files listed here.

Suppose you still experience that Mac won't connect to internet but other devices will; it's time to renew the DHCP lease.

Renew your DHCP lease

DHCP (Dynamic Host Configuration Protocol) assigns unique IP addresses to your devices, including router, iPhone, Mac, etc., so that they can be found on the network and communicate with each other.

The DHCP may be experiencing an issue or being expired; consequently, your Mac connects to WiFi but no internet. Fortunately, the lease can be easily renewed.

  1. Open the Apple menu and choose System Preferences > Network.
  2. Click WiFi > Advanced.
  3. Select the TCP/IP tab.
  4. Tap on Renew DHCP Lease, followed by OK.renew DHCP on Mac to get back Wi-Fi

Many have the "WiFi connected but no internet on Mac" problem fixed after going through the steps above. If not, there may be some issues with your DNS provider.

Change your Mac's DNS

DNS (Domain Name System) translates the domain names we enter in browsers (like iboysoft.com) to the correspondent IP addresses so that the browser can understand and load internet resources. A slow, offline, or faulty DNS provider may result in Mac connecting to WiFi but no internet. 

Therefore, if your Mac is connected to WiFi but Safari won't work, changing your DNS provider to a free public service like Google might help.

Fix WiFi is connected but no internet on Mac:

  1. Close all the open browsers.
  2. Navigate to the Apple menu > System Preferences > Network.
  3. Choose Wi-Fi > Advanced.

Quit mDNSResponder

Mac connecting to WiFi but no internet could result from the mDNSResponder process as users reported successful internet access after stopping the process from running. You can quit mDNSResponder from the Activity Monitor.

  1. Launch Activity Monitor from Finder > Applications > Utilities.
  2. Locate mDNSResponder, select it and click the ✖ icon to stop the process.quit MDNSponder on Mac to regain internet

Turn off VPN or security software

If you have your MacBook connected to WiFi but no internet after updating to macOS Monterey, PIA (Private Internet Access) may be the issue. The same goes for other security software like DNSCrypt or anti-virus programs. If you have them configured, try uninstalling or turning them off and see if your WiFi starts to work.

Disabling the above software should have resolved the issue of MacBook Pro losing WiFi connection if you have one set up. Otherwise, continue with the next solution.

Factory reset your router

If you find your MacBook Air connected to WiFi but no internet using a specific network, factory resetting the router while keeping the same username, password, and security protocol can get your internet back. Follow these steps to fix Mac WiFi connected but no internet:

  1. Keep your router plugged in.
  2. Locate the reset button on the back or bottom of the router.
  3. Use a paperclip or the kind to hold down the button for 30 seconds.

Remove your WiFi and reconnect

Some manage to get back on the internet after removing and reading WiFi on Mac. If your MacBook has WiFi but no internet, you are recommended to do the same. If you don't remember your WiFi password, note it down before getting started.

Update macOS

On the occasion that you have your MacBook connected to WiFi but no internet on macOS Monterey, Big Sur, or Catalina, it's a good idea to update the Mac operating system to the latest available. In the hope that a newer update will solve the software bugs in the current macOS. But if you have entirely lost the internet connection, this method will be out of the question. If so, move on to the next one.

Update the WiFi router

Fix WiFi is connected but no internet on Mac:

  1. Open a web browser on the computer that has no problem connecting to the internet with your WiFi.
  2. Type in the WiFi router's IP address.

  4. Enter your router's username and password, which you can find on the manual or the router itself.
  5. Locate the section for Firmware Update.
  6. Visit the router manufacturer's site.
  7. Download the firmware update file.
  8. Extract the firmware files out to your desktop.
  9. On the Firmware Update page you found before, tap on Choose File or Browse.
  10. Select the update file and wait for the process to be done.
  11. Restart the router if it doesn't happen automatically.

If the internet is still not working, take a look at Apple's guide for Wi-Fi router settings and access points.

Prioritize network

If you noticed your MacBook connected to WiFi but no internet on Catalina or other macOS versions, it may have connected to a saved WiFi network that's currently inactive. It's best to check if working WiFi is arranged on top of the Preferred Networks.

Fix having connected to WiFi but no internet on Mac:

  4. Click on Advanced.
  5. Drag your preferred network to the top.
  6. Tap on OK.

If you find the Wi-Fi internet speed is abnormal, you can run macOS networkQuality command on the Terminal app to test the network quality.

Run Wireless Diagnostics on Mac
