Common causes
Wi-Fi can disconnect because of weak signal, crowded wireless channels, adapter power saving, outdated drivers, a damaged network profile, or router issues that affect every device.

Windows fixes
If the laptop stays connected to Wi-Fi but the internet itself stops working, switch to the Wi-Fi Connected But No Internet guide instead of treating it like a disconnect problem.
Router checks
Restart the router, move closer for a signal test, reduce obstacles, try the 2.4 GHz and 5 GHz bands, and check whether other devices disconnect at the same time.
If no networks appear at all, use the No Wi-Fi Networks Found in Windows guide because that points to a different layer of the problem.
Common reasons include weak signal, Wi-Fi adapter power saving, driver issues, a corrupted network profile, router problems, or changes after an update.
Yes. Windows power management can turn down or suspend the Wi-Fi adapter, especially on battery power.
Updating or rolling back the Wi-Fi driver can help if disconnects started after a Windows update, driver update, or device change.
If multiple devices disconnect, or the problem happens far from the router, check router placement, restart the router, and test another network if possible.
