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

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 – Fixes

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.

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
