Are you tired of dealing with a Mac that keeps disconnecting from Wi-Fi every time it goes to sleep? You’re not alone. This frustrating issue has been plaguing Mac users for years, and it’s not just a minor annoyance – it can be a major productivity killer. In this article, we’ll explore the reasons behind this issue and provide you with some practical solutions to help you stay connected.
Understanding the Issue
Before we dive into the solutions, let’s take a closer look at what’s happening when your Mac disconnects from Wi-Fi when it goes to sleep. When your Mac is in sleep mode, it’s not completely powered down – it’s still using some power to maintain a connection to your Wi-Fi network. However, if your Mac is configured to disconnect from Wi-Fi when it’s not in use, it will drop the connection when it goes to sleep.
This can be caused by a variety of factors, including:
- Power management settings: Your Mac’s power management settings may be configured to disconnect from Wi-Fi when it’s not in use to conserve battery life.
- Wi-Fi network settings: Your Wi-Fi network settings may be configured to disconnect devices that are not actively using the network.
- Router settings: Your router’s settings may be configured to disconnect devices that are not actively using the network.
Troubleshooting Steps
Before we move on to the solutions, let’s go through some troubleshooting steps to help you identify the cause of the issue.
Check Your Power Management Settings
To check your power management settings, follow these steps:
- Click the Apple menu and select System Preferences.
- Click Energy Saver.
- Click the Options tab.
- Make sure the “Wake for Wi-Fi network access” checkbox is selected.
If this checkbox is not selected, your Mac will disconnect from Wi-Fi when it goes to sleep.
Check Your Wi-Fi Network Settings
To check your Wi-Fi network settings, follow these steps:
- Click the Apple menu and select System Preferences.
- Click Network.
- Select your Wi-Fi network from the list of available networks.

If this checkbox is selected, your Mac will disconnect from Wi-Fi when it goes to sleep.
Check Your Router Settings
To check your router settings, you’ll need to log in to your router’s web interface. The steps to do this vary depending on your router model, so consult your router’s documentation for instructions.
Once you’re logged in, look for the Wi-Fi settings and make sure that the “Disconnect devices that are not actively using the network” option is not selected.

Why does my Mac keep disconnecting from Wi-Fi when it goes to sleep?
Your Mac may be disconnecting from Wi-Fi when it goes to sleep due to a feature called “Wake on Wireless” being disabled. This feature allows your Mac to maintain a connection to a Wi-Fi network even when it’s in sleep mode. If this feature is disabled, your Mac will disconnect from the Wi-Fi network when it goes to sleep. Additionally, other factors such as network congestion, router issues, or conflicts with other devices on the network may also cause your Mac to disconnect from Wi-Fi.
To resolve this issue, you can try enabling the “Wake on Wireless” feature on your Mac. You can do this by going to System Preferences > Energy Saver > Options, and selecting the “Wake for Wi-Fi network access” checkbox. You can also try restarting your router, moving your Mac closer to the router, or switching to a different Wi-Fi network to see if the issue persists.
How do I enable Wake on Wireless on my Mac?
To enable Wake on Wireless on your Mac, go to System Preferences > Energy Saver > Options. In the Options window, select the “Wake for Wi-Fi network access” checkbox. This will allow your Mac to maintain a connection to a Wi-Fi network even when it’s in sleep mode. Make sure that your Mac is connected to a Wi-Fi network before enabling this feature.
Once you’ve enabled Wake on Wireless, your Mac should be able to stay connected to the Wi-Fi network even when it’s in sleep mode. However, if you’re still experiencing issues with your Mac disconnecting from Wi-Fi, you may want to try restarting your router or moving your Mac closer to the router to improve the connection.
What are some common causes of Wi-Fi disconnection on Macs?
There are several common causes of Wi-Fi disconnection on Macs, including network congestion, router issues, and conflicts with other devices on the network. If your router is outdated or not configured properly, it may not be able to maintain a stable connection to your Mac. Additionally, if there are too many devices connected to the same network, it can cause congestion and lead to disconnections.
Other factors such as physical obstructions, interference from other devices, and software issues can also cause Wi-Fi disconnections on Macs. To resolve these issues, you can try restarting your router, moving your Mac closer to the router, or switching to a different Wi-Fi network. You can also try updating your router’s firmware or resetting it to its factory settings.
How do I troubleshoot Wi-Fi disconnection issues on my Mac?
To troubleshoot Wi-Fi disconnection issues on your Mac, start by restarting your router and your Mac. This can often resolve connectivity issues and improve the stability of your Wi-Fi connection. If the issue persists, try moving your Mac closer to the router or switching to a different Wi-Fi network.
You can also try using the Wi-Fi Diagnostics tool on your Mac to identify and resolve connectivity issues. To access this tool, go to Applications > Utilities > Wi-Fi Diagnostics. Follow the prompts to run the diagnostic test and see if it identifies any issues with your Wi-Fi connection.
Can I prevent my Mac from disconnecting from Wi-Fi when it goes to sleep?
Yes, you can prevent your Mac from disconnecting from Wi-Fi when it goes to sleep by enabling the “Wake on Wireless” feature. This feature allows your Mac to maintain a connection to a Wi-Fi network even when it’s in sleep mode. To enable this feature, go to System Preferences > Energy Saver > Options, and select the “Wake for Wi-Fi network access” checkbox.

Will enabling Wake on Wireless affect my Mac’s battery life?
Enabling Wake on Wireless on your Mac may affect its battery life, as it allows your Mac to maintain a connection to a Wi-Fi network even when it’s in sleep mode. This can cause your Mac to consume more power, especially if it’s connected to a Wi-Fi network that requires frequent authentication or has a weak signal.
However, the impact on battery life is typically minimal, and you can adjust your Mac’s sleep settings to balance battery life with Wi-Fi connectivity. You can also try disabling Wake on Wireless when you’re not using your Mac to conserve battery life.
