- Forget and reconnect to the network. This rebuilds the saved Wi-Fi profile.
- Check adapter power management. Prevent Windows from turning off the Wi-Fi adapter to save power.
- Update or roll back the Wi-Fi driver. This is useful when the issue starts after an update.
- Run Network Reset only if needed. Use it after simpler fixes fail because it removes saved network settings.
Router checks
Router-side 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.
