If it does, the behavior may be part of Windows sleep power management; if it stays offline, check the Wi-Fi adapter’s power setting and wireless power plan. These instructions focus on Windows, where the relevant controls are documented. Mac and Chromebook settings differ.
First determine when Wi-Fi is unavailable
Test whether the connection returns after you wake the computer. A Windows PC with Modern Standby may limit network activity while asleep—particularly on battery—yet make connectivity available again when it resumes. In that case, Wi-Fi being unavailable during sleep is not necessarily a fault. If the computer remains disconnected after waking, continue with the checks below.

Stop Windows from turning off the Wi-Fi adapter
- Open Device Manager and expand Network adapters.
- Open the properties for your Wi-Fi adapter and select Power Management.
- If the option is present, clear Allow the computer to turn off this device to save power, then select OK. The tab or checkbox may not be available on every device. See Microsoft’s Wi-Fi troubleshooting guidance.
Set wireless power saving to maximum performance
If the connection still drops, open your power plan’s advanced settings and look for Wireless Adapter Settings. Microsoft recommends setting Power Saving Mode to Maximum Performance for frequent Wi-Fi drops. The setting’s availability and labels can vary by Windows version and device.

Review Windows’ sleep network option
Microsoft documents a battery setting called When my PC is asleep and on battery power, disconnect from the network. Its documented choices include Always, Managed by Windows and Never; choose a choice other than Never if that option appears. The documented path is from Windows 10-era guidance, and settings may differ on your PC. In Windows 11, sleep and hibernate timeouts are under Settings > System > Power & battery; this does not mean every device exposes the same network-disconnection control. See Microsoft’s battery-saving guidance.
Modern Standby uses power-management behavior that can limit connectivity on battery and allow network activity for selected scenarios, with connectivity ready when the PC resumes. That is why a universal “keep Wi-Fi on throughout sleep” switch may not be available. Microsoft describes this behavior in its Modern Standby network connectivity documentation.

If Wi-Fi still does not reconnect after wake
Check the driver
In Device Manager, note the Wi-Fi adapter’s model and driver version before making changes. Check Windows Update and the computer or adapter manufacturer’s support page for a suitable driver. If the adapter is missing or reports an error, updating or reinstalling its driver may help; use a driver intended for your exact computer or adapter.

Compare networks and devices
- Try another trusted Wi-Fi network. If the problem occurs only on one network, investigate that network or its router; if it follows the computer across networks, focus on the computer and adapter.
- Check whether other devices on the same Wi-Fi network lose connectivity at the same time. If they do, the router or internet service may be involved rather than the sleeping computer.
Use network reset only as a later step
Try simpler checks first. Microsoft notes that Windows network reset removes installed network adapters and their settings, so you may need to configure network-related settings again afterward. See Microsoft’s Wi-Fi troubleshooting guidance for its reset instructions.
