Your MacBook might be on Wi-Fi but with no Internet connection for a range of different reasons. It could be down to your router, your Internet service provider, or your MacBook software.

Jun 27, 2011 'Why can't I connect my Mac to the internet' Most connections work by your Mac connecting to a modem/router, which connects to the internet. Things could be wrong between your computer and the. If your web browser, email program, or any of a hundred other internet-connected apps on your Mac starts complaining about not having a connection, you may have to do a bit of sleuthing to figure. Click on the Apple Logo in top-menu bar and select System Preferences in the drop-down menu. On System Preferences screen, click on the Network option. On the Network screen, select WiFi Network in left menu bar and click on the Advanced button. On the next screen, select the WiFi.

Try these steps if you can't connect to any of these apps:

Check the system status page

Check Apple’s System Status page to see if there’s an outage for a service in your country or region.

Make sure that your device is connected to the Internet

Use any Internet browser to connect to any website. If nothing loads, use another device on the same network to see if it can connect to any website. If no other devices can access the Internet, turn off your Wi-Fi router, then turn it on again to reset it. If you still can’t connect to your Wi-Fi network, contact your Internet provider for more help. If only your first device can’t connect to the Internet, get help with Wi-Fi on your iPhone, iPad, or iPod touch, Apple Watch, Apple TV, or Mac.

If you use cellular service to connect to the Internet on your iPhone or iPad, make sure that you have cellular data turned on for the app that you're using. To do this, open the Settings app, tap Cellular, then turn on Cellular Data.

Update your software

Update to the latest version of iOS or iPadOS, macOS, tvOS, watchOS, or software for your non-Apple device. Then try to connect again.

Check the date and time

Make sure that the date and time on your device are set correctly for your time zone.

On your iPhone, iPad, iPod touch: Open the Settings app. Tap General, then tap Date & Time. Get more help with date and time.
On your Mac: Open System Preferences, then choose Date & Time.
On your Apple TV: Go to Settings > General > Date and Time.

If the date and time are incorrect, update them or turn on the option to set date and time automatically.

If you see a different connection alert message

Use the steps above if you see one of these error messages:

'Cannot connect to the iTunes Store. An unknown error has occurred.'
'We could not complete your iTunes Store request. The iTunes Store is temporarily unavailable. Please try again later.'
'Could not connect to the iTunes Store. Make sure your network connection is active and try again.'
'We could not complete your iTunes Store request. The network connection could not be established. There was an error in the iTunes Store. Please try again later.'

Wi-Fi problems on macOS Big Sur/Mojave/Catalina

Wi-Fi connection — it is central to intelligent life on Earth. But there could be numerous reasons your Mac won’t connect to Wi-Fi: a new software update, broken Wi-Fi preferences, or several networks conflicting with each other. Below we’ll explain what to do when you can’t connect to Wi-Fi or your connection is constantly dropping off.

So here go the most common symptoms for Wi-Fi problems on Mac:

Mac won’t connect to internet, but other devices will
Mac connected to Wi-Fi, but no Internet access
Wi-Fi connection keeps turning off
Slow or unstable Wi-Fi connection on Mac?

Tip: In case your Mac is generally slow, which obviously affects the Internet too, you may start with fixing the performance issues first. The quickest is to delete junk and old caches from your drive and browsers. Here you can download the free version of CleanMyMac app. It helps to remove the unwanted files, bloatware, and junky web browser extensions. In a few minutes, your Mac should be relatively fresh.

See if your Mac keeps having Wi-Fi connection issues. If it does, read on.

Ways to fix Wi-Fi on Mac

Run the default Wi-Fi assistants

To troubleshoot Wi-Fi problems on Mac it’s good to start with native tools that came with your OS.

Go to Apple Menu -> System Preferences -> Network

This window lets you inspect your Wi-Fi preferences. If your Mac has internet connection problems, click Assist me as shown in the screenshot below. This will launch a built-in Diagnostics tool.

Did it solve the problem? Good news there’s another instrument provided by Apple, a Wireless Diagnostics app.
Option + click the Wi-Fi icon in the top right corner
Click Open Wireless Diagnostics…

Delete and reset Wi-Fi network settings

This step will reconfigure your existing Wi-Fi settings and launch your network experience from scratch. But before you begin, we seriously recommend to back your Mac up using Time Machine.

Mac Not Connecting To Wifi

Turn off Wi-Fi and close shut down your browsers
Open Finder -> Go -> Go to Folder..
Paste in the following line:

4. Select the files listed below (as shown in the screenshot)

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

5. Move these files to Trash (without deleting)
Or move them to a new folder on your Desktop.
6. Restart your Mac
Now you will have to revisit Wi-Fi preferences (Click Open Network Preferences under Wi-Fi icon). Turn Wi-Fi on and select your Wi-Fi network again.

The path above proved to be a good remedy in cases when Wi-Fi connection drops off after upgrading to macOS Catalina. If the issue persists, you may consider to clean install macOS Catalina.

Wi-Fi won't turn on after sleep mode on Mac

In some cases, sleep mode settings is the reason your Wi-Fi drops off on Mac and wouldn’t turn on again. Try this simple fix which many users found helpful:

Go to System Preferences -> Energy Saver
Disable Wake for Wi-Fi network option

Check your Wi-Fi now (cross your fingers). Did it do the trick? If not, let’s move on to the next step.

Flush DNS cache

Another way to fix Mac Wi-Fi not working is to flush your DNS cache. DNS service helps your Mac find IP-addresses, much like in a phone book. It has a cache folder of its own. Removing these cache files is helpful when your Wi-Fi slows down at random or you can’t access certain websites.

To save you from meddling with critical system folders, here’s a quick workaround.

1. Download DNS Flusher (it’s built into CleanMyMac X — get it here).
2. Go to Maintenance tab and tick Flush DNS cache

That’s all — and this solution is 100% free and takes no more than a minute.

By the way, CleanMyMac X is pretty much an indispensable tool if you want to keep your Mac clean and junk-free. It removes up to 74 GB of junk files on an average Mac, so give it a spin, just in case.

Reboot your Wi-Fi router

Plug off your router and leave it for a minute or two. This way you will know if your Mac won’t connect to Wi-Fi because of router issues. Plug your router back in and try to connect other Wi-Fi devices in the room.

Additionally, try placing your router in a different place. Your Wi-Fi signal could be lost due to neighboring network or it is catching a “dead-zone” in your house. If your room allows it, move it right in the center of the room. Fewer barriers, the better signal.

Still no Wi-Fi connection on Mac? Switch off the Bluetooth

Bluetooth devices often interfere with Wi-Fi, especially if the Wi-Fi signal is weak. It’s because both rely on radio frequencies to work. So one more idea to fix your Wi-Fi not working on Mac problem is to inspect the Bluetooth settings.

Try disconnecting the Bluetooth and see if the problem persists.

Go to Apple menu -> System Preferences
Select Bluetooth
Then click Turn Bluetooth off

Update your router firmware

If you are using Apple Airport router you’ll need Airport Utility to perform the update. Obviously, this step requires an internet connection. You can connect via cable if your Wi-Fi doesn’t work on Mac.
Go to Applications
Type Airport Utility in the search bar

You’ll see your Airport base station. If you see a red notification badge next to the base name, click it for more details. If the update is available, the app will show you the Update button.

Customize MTU and DNS settings to fix Wi-Fi on Mac

MTU stands for Maximum Transmission Unit and describes the packet size that is exchanged via the network (measured in bytes). The solution described below implies lowering MTU size which should make your WI-Fi connection less laggy. While customizing DNS location has also proved effective to solve even the most bitter Wi-Fi problems on Mac.

But don’t let these geeky terms put you off. The path takes just about a minute and you’ll be proud to have fixed your Mac Wi-Fi not working, the Apple Genius way.

Step 1.

Go to System Preferences -> Network
Select Wi-Fi in the left panel
See Location menu on top
Click Edit Locations…

Step 2.
Now create a new location by clicking [+] plus button. Name it anything you like. Click Done.

Step 3.

Then choose your standard Wi-Fi connection under Network Name
Click Advanced
Go to TCP/IP tab and click Renew DHCP lease .

Step 4.

Go to DNS tab and by clicking [+] buttons enter 8.8.8.8 and 8.8.4.4 as IP-addresses, each in a separate line. These two are Google’s alternative DNS servers that the company recommends using — they are safe. But before you do this, make sure to copy your current DNS address on a piece of paper.

Step 5.

Go to a Hardware tab from the previous step.
Under Configure dropdown menu select Manually
Click MTU and set the custom size of 1453
Click Apply/brain-wave-app-mac.html.

Well done. Your Mac Wi-Fi not working should have been resolved.

Still no or poor Wi-FI Connection on Mac?

Maybe all this time you’ve been digging in the wrong place as the problem is in your Mac itself. It might need some basic tidying up and maintenance to run faster. Try giving it a full clean with a tool like CleanMyMac X (it's my favorite among similar Mac tune-up apps — here's the official free download from the developer site). Hopefully, once your Mac is clean and up to speed again, your Wi-Fi should get back to norm.

May the Wi-Fi be with you. Thanks for reading.
