If you've followed the steps to connect your Mac to a Wi-Fi network, but the connection to your network or the Internet isn't reliable, the steps in this article might help.

Check for Wi-Fi recommendations

When your Mac tries to connect to a Wi-Fi network, it checks for issues that affect its ability to create a fast, stable, and secure connection. If an issue is detected, the Wi-Fi status menu in the menu bar shows a new item: Wi-Fi Recommendations. Choose it to see recommended solutions.

Wi-Fi recommendations are available in macOS Sierra or later.

Analyze your wireless environment

Your Mac can use Wireless Diagnostics to perform additional analysis.

  1. Quit any apps that are open, and connect to your Wi-Fi network, if possible.
  2. Press and hold Option (Alt) ⌥ key, then choose Open Wireless Diagnostics from the Wi-Fi status menu .
  3. Enter your administrator name and password when prompted.

Wireless Diagnostics begins analyzing your wireless environment:

If the issue is intermittent, you can choose to monitor your Wi-Fi connection:


When you're ready to see recommendations, continue to the summary. Wireless Diagnostics asks for optional information about your base station or other router, so that it can include that in the report it saves to your Mac.

Click the info button next to each item in the summary to see details about that item. Wi-Fi best practices are tips that apply to most Wi-Fi networks.


Back up or make note of your network or router settings before changing them based on these recommendations—in case you need to use those settings again.

Monitor your Wi-Fi connection

Your Mac can monitor your Wi-Fi connection for intermittent issues, such as dropped connections. Follow the steps to analyze your wireless environment, but choose 'Monitor my Wi-Fi connection' when prompted.

During monitoring, a window shows that monitoring is in progress. Monitoring continues as long as this window is open and you're on the same Wi-Fi network, even when your Mac is asleep.

If Wireless Diagnostics finds an issue, it stops monitoring and shows a brief description of the issue. You can then resume monitoring or continue to the summary for details and recommendations.

Create a diagnostics report

Wireless Diagnostics automatically saves a diagnostics report before it displays its summary. You can create the same report at any time: press and hold the Option key, then choose Create Diagnostics Report from the Wi-Fi status menu . It can take your Mac several minutes to create the report.

  • macOS Sierra and later saves the report to the /var/tmp folder of your startup drive, then opens that folder for you.
    To open the folder manually, choose Go > Go to Folder from the Finder menu bar, then enter /var/tmp.
  • OS X El Capitan or earlier saves the report to your desktop.

The report is a compressed file with a name that begins 'WirelessDiagnostics.' It contains many files that describe your wireless environment in detail. A network specialist can examine them for further analysis.

Use other diagnostics utilities

Wireless Diagnostics includes additional utilities for network specialists. Open them from the Window menu in the Wireless Diagnostics menu bar:

  • Info gathers key details about your current network connections.
  • Logs enables background logging for Wi-Fi and other system components. The result is saved to a .log file in the diagnostics report location on your Mac. Logging continues even when you quit the app or restart your Mac, so remember to disable logging when you're done.
  • Scan finds Wi-Fi routers in your environment and gathers key details about them.
  • Performance uses live graphs to show the performance of your Wi-Fi connection:
    • Rate shows the transmit rate over time in megabits per second.
    • Quality shows the signal-to-noise ratio over time. When the quality is too low, your device disconnects from the Wi-Fi router. Factors that affect quality include the distance between your device and the router, and objects such as walls that impede the signal from your router. Learn more.
    • Signal shows both signal (RSSI) and noise measurements over time. You want RSSI to be high and noise to be low, so the bigger the gap between RSSI and noise, the better.
  • Sniffer captures traffic on your Wi-Fi connection, which can be useful when diagnosing a reproducible issue. Select a channel and width, then click Start to begin capturing traffic on that channel. When you click Stop, a .wcap file is saved to the diagnostics report location on your Mac.

When Wi-Fi stops working on a Mac, it can be a nightmare. All of a sudden, you can't make progress or even start on something without an internet connection.

Most of us take the always-on Wi-Fi connectivity for granted. Even when traveling thousands of miles from home in developing countries, most businesses, homes, and even public spaces are equipped with modems that broadcast wireless internet.

How to fix Mac won't connect to Wi-Fi

In many respects, Wi-Fi has become a commodity, a necessity for the smooth functioning of business, academia, governments, and the media. Thanks to Wi-Fi, we are more connected than ever before. Our music, emails, and even shopping are dependent upon it.

So if you've ever had Wi-Fi connectivity issues on a Mac, you might want to save this article for offline reading, just in case. There are a few ways to these problems.

1. Check your macOS

When Mac users update their operating system, Wi-Fi connectivity can vanish.

At the time of the original version of El Capitan, a lot of users found they couldn't connect to Wi-Fi, which made it harder for Apple to release an update that included a patch solving this particular problem. In some cases, users had to download the updated version using a phone as a Personal Hotspot, which caused other problems, such as extra data costs.

Unfortunately, as a result of the recent macOS Catalina release, some users were experiencing the same problem.

Turn Wi-Fi on and off

One way to fix this is to switch your Wi-Fi off and back on again. At the same time, it may also be worth changing the name of your home (or office) network and setting a new password, which you can do through your internet provider. If necessary, you should be able to do this through a mobile phone, and then check whether your Mac will connect again.

2. Wi-Fi signal issues

Sometimes it's Wi-Fi signal causing all the problems. If that's what you're suspecting, here are the possible solutions:

Run a speed test and get a better signal

A good way to work out whether the problem is the Mac or Wi-Fi itself is using an analyzer app. To analyze your Wi-Fi network signal strength, use WiFi Explorer or NetSpot.

You may find that furniture and walls in your place are blocking or reducing the signal. When you are checking the results, it might be helpful to move your wireless router to a better location or ask if your broadband provider can install a signal booster.

Make WiFi faster on Mac

Download Setapp to declutter your Mac and make WiFi powerful. There's at least one tool that handles the task perfectly.

Don't trust public networks

Ensure your personal information is securely protected on public Wi-Fi. While every public network can potentially 'read' the data you send and receive, dealing with sensitive information on a public network is a huge risk. To stay safe, control your network connection with Activity Monitor or iStat Menus— perfect for real-time tracking of what's being sent and received via network.

To prevent suspicious apps from accessing your data, use TripMode. The app allows to activate blocking right from your menu bar. So it's a one-switch solution that you can use every time your Mac connects to a public network.

Secure your private network

Using your own network is certainly more secure than accessing public ones. But it's never a risk-free deal. Private or public, there are a few tips that will help you stay safe:

  1. Change the SSID name so that it's hard to identify the type of router you use.

  2. Solidify encryption. There are several options for Wi-Fi protection, out of which WPA2 is considered one of the most secure.

Use a VPN client. A reliable VPN app like Shimo will help you handle and place restrictions on the network you use. Plus, it has a module for setting multiple connections.

3. Forget your Wi-Fi network

Sometimes you need to let go to reconnect again. That also works for Wi-Fi signals.

Assuming you've already tried rebooting your Mac and router, disconnecting entirely is a tried-and-tested solution.

Here are the steps for doing this slightly trickier fix:

  1. Turn off Airport
  2. Go to Systems Preferences
  3. Network > Select Wi-Fi
  4. Click Advanced
  5. Select the network you want to disconnect from and click on minus, then agree.

Do that on any other device you can't connect with, and then start the process to connect to that network, entering the password, and (fingers crossed) you should be connected again.

4. Declutter your Mac

One of the other problems that could be causing connectivity issues is bloat, junk, and clutter. Over time, Macs can get full of things they really don't need to store, such as cache files, email downloads, browser extensions and viruses. All of these slow down and overheat Macs, which could impact your connectivity as well.

Then, use CleanMyMac to clean up your macOS. This app is an effective solution and much-needed antidote to slow Mac performance. You can use it to dig up junk cluttering up Macs, delete unused apps completely, tidy up email folders and attachments, and remove plugins you don't need.

So if you're wondering how to fix Wi-Fi and you've already tried every network-related strategy, it's probably your Mac's fault. CleanMyMac X will clear caches, browser extensions, and declutter disks and hard drives so that your Mac is operating at peak performance again. It also includes health monitors, so you can avoid similar issues in the future. Dive into Extensions, Uninstaller, and System Junk modules to clear away whatever can hinder your network connection.

5. Contact your broadband provider

Your broadband provider should have a speed testing function within wireless routers or your customer account portal. Increasing the speed, or switching to a faster provider, could be the solution to Wi-Fi connectivity problems, providing you've tried everything else first.

Prepare beforehand

Given you've already saved this article for offline reading, it might also be a good idea to download all the apps mentioned above, so you don't have to use your phone's data when the Wi-Fi crisis hit, which, hopefully, it never will.
