Experiencing slow WiFi on your MacBook can be due to several factors, including MacBook settings, router problems, or your Internet Service Provider.

Start by testing your internet speed on multiple devices using a tool like speedtest.net.

If only your MacBook is slow, consider these fixes: run the built-in Wireless Diagnostics Tool, reset your MacBook’s WiFi settings, update your macOS, or reset your NVRAM.

If all devices are slow, try troubleshooting your router: check its location and signal interference, status lights, and consider restarting or resetting it.

Sometimes even switching web browsers can also enhance WiFi performance.

Understanding Why Your MacBook's Wi-Fi is Slow

The first step to fixing your problem is understanding what's causing it. By identifying the cause, you can apply the most effective solution and save yourself a lot of time and frustration.

1. Your MacBook: Issues with the hardware or software settings in your MacBook can cause slow Wi-Fi. These issues can range from outdated software to incorrect Wi-Fi settings.

2. Your Internet and Wi-Fi Equipment: Problems with your router or modem, such as old firmware, improper placement, or simply needing a reboot, can affect your Wi-Fi speeds.

3. Your Internet Service Provider (ISP): Sometimes, the issue may not be within your home network but rather with your ISP. If they're experiencing problems or performing maintenance, your Wi-Fi speed might be affected.

How to fix Slow WiFi on your MacBook - Test Connection Speed

How to Fix Slow WiFi on your MacBook

The first step is to check where the problem is, your WiFi or Internet Service Provider (ISP) or something else. By testing the connection speed of my internet, I was able to pinpoint the problem more clearly.

I did this by going to speedtest.net and then running the test. (There are other sites like fast.com too) This way I knew if I was getting advertised speeds from my ISP. 

I recommend running this test on multiple devices. If the result is slow on all devices, then the problem might be with your ISP. But if the internet speeds are slow only on your Mac, then the problem is with your MacBook.

In any case, if the speeds are slow then you can try out our fixes below. Some of these fixes are targeted to fix your internet in general while some will fix issues on your Mac.

How to fix Slow WiFi on your MacBook - Troubleshoot your router

Troubleshooting your router will fix any general internet issue. I did the following when WiFi speeds were down on all my devices. 

Check router location and signal interference

If your Mac and internet router are not close by or if there's a lot of interference then you won't have a good connection.

So make sure that your router is located in an optimal location and covers all your devices. The closer it is to your Mac the better your WiFi speeds will be. 

Signal interference can be caused due to walls and other electronic devices in between your Mac and router. So make sure the path between your router and Mac is clear. 

Check router status lights

All routers have status lights on them. These lights will let you know about the internet connection status. If the LED on your router is solid then the connection is stable but if it's flickering then it means that there is some issue.

Also note that different router models can have different indication LEDs, so check your router manual for more info. 

Restart or reset your router

If everything looks good, as if you are in your router's vicinity and the lights are all good, then restarting or resetting your router might help. Power off your router and turn it back on 

If the issue is not fixed then check your router's manual to know how to reset it. Most of the time a restart would be enough, if not resetting might be the way to go.

How to fix Slow WiFi on your MacBook - Switch Web Browsers

Sometimes, the problem may not be your Mac or router but rather the web browser you are using. Sometimes a bug or a glitch can make your web browser perform unusually slow.

So try switching web browsers and see if the WiFi performance increases. 

Some of my favorite web browsers for Mac are Google Chrome, Safari, and Mozilla Firefox. Also, check if there's any download happening in the background. Downloading large amounts of data can slow down WiFi speeds across all your devices. 

Run the Wireless Diagnostics Tool
