What You'll Learn
A possible fix is to change the IPv6 setting
If your laptop is experiencing Wi-Fi issues when waking from sleep mode, a possible fix is to change the IPv6 setting. This issue may occur when the operating system turns off the Wi-Fi adapter to save power or due to problems with the network adapter.
- Go to Control Panel > Network and Internet > Network and Sharing Center.
- In the pop-up window, click on "Change adapter settings".
- Right-click on the internet connection you are using and select "Properties".
- In the pop-up window, uncheck the "Internet Protocol Version 6 (TCP/IPv6)" option.
- Click "OK" to save the changes.
By disabling IPv6, you are modifying the network settings to retain the Wi-Fi connection when your laptop goes into sleep mode. This setting adjustment instructs the laptop to keep the Wi-Fi adapter active, ensuring a seamless connection upon waking the device.
If the IPv6 setting change does not resolve the issue, there are additional troubleshooting steps you can take. One suggestion is to disable any third-party antivirus software temporarily to determine if it is interfering with your internet connection. Antivirus software can sometimes interrupt the connection to protect your PC from potential threats. Disabling it can help pinpoint if it is a contributing factor to the Wi-Fi issue.

Check the laptop's power settings
If your laptop is experiencing Wi-Fi issues when waking up from sleep mode, it is worth checking the laptop's power settings. Here is a detailed guide to help you with this process:
Firstly, open the Start menu by clicking on the Windows icon in the bottom-left corner of your screen. Once the Start menu is open, search for "Device Manager" by typing it into the search box. The Device Manager will allow you to manage your laptop's power settings and hardware devices.
After opening the Device Manager, locate the "Network Adapters" option and expand it by clicking on the arrow next to it. Under Network Adapters, you will find the Wi-Fi adapter. Right-click on the Wi-Fi adapter and select "Properties" from the menu. This will open the Properties window, where you can configure the settings for your Wi-Fi adapter.
In the Properties window, navigate to the "Power Management" tab. This tab contains settings that control how your laptop uses power and can impact its behaviour when sleeping or waking up. Ensure that the "Allow the computer to turn off this device to save power" option is unchecked. By unchecking this option, you are instructing the laptop not to turn off the Wi-Fi adapter to save power, which could be causing the Wi-Fi issues when waking up from sleep mode.
Next, we will focus on the power plan settings. Go back to the Start menu and type "Edit Power Plan" in the search box. This will allow you to adjust advanced power settings, including those related to your wireless adapter. Open the "Edit Power Plan" window and select the "Change advanced power settings" option.
In the advanced power settings, navigate to "Wireless Adapter Settings" and then "Power Saving Mode". It is recommended to set both the "On Battery" and "Plugged In" options to "Maximum Performance". This will ensure that your wireless adapter is always operating at its full potential, even when the laptop is running on battery power.
After making these changes, restart your laptop and test its sleep mode to see if the Wi-Fi issues have been resolved. These steps should help address any problems related to power settings, but if the issue persists, you may need to explore other troubleshooting options or seek further technical support.

Try disabling and re-enabling the wireless network
If you're experiencing WiFi issues when your laptop wakes from sleep mode, one potential solution is to disable and re-enable the wireless network adapter. This can be done through the Device Manager, which allows you to view and manage your hardware devices.
Here's a step-by-step guide to disabling and re-enabling your wireless network adapter:
- Open the Device Manager: Press the Windows logo key and 'R' simultaneously on your keyboard to open the Run box. Type "devmgmt.msc" and click OK.
- Locate your wireless network adapter: Double-click on "Network adapters" to expand the category. Then, double-click on your wireless network adapter.
- Disable and re-enable the adapter: In the properties pane, click on the "Driver" tab. If your adapter is enabled, you will see the option to "Disable Device." Click on this option to disable the adapter. Once it has been successfully disabled, you can then click on the "Enable Device" option to re-enable it.
- Restart your computer: After making these changes, it is recommended to restart your computer to allow the changes to take effect.
- Test your WiFi connection: Once your computer restarts, access your WiFi settings and test your connection to see if the issue has been resolved.
It is important to note that some laptops, such as certain HP or Lenovo models, have a physical switch or key to turn the WiFi adapter on and off. In these cases, you can simply use the designated switch or key combination to disable and re-enable the wireless network adapter without going through the Device Manager.
Additionally, you can try updating your WiFi adapter driver to the latest version. This can be done either manually by downloading the latest driver from the manufacturer's website or automatically through Windows Update. However, keep in mind that you will need an alternative internet connection, such as an Ethernet connection, to update your WiFi driver if you are currently unable to connect to WiFi.
