Answer 2

There could be several reasons why your PC is failing to automatically log on to your Wi-Fi network. Here are some common causes and potential remedies:

1. Network Profile Settings: Sometimes, the network profile settings can change, causing the PC to forget the Wi-Fi password. You can check the settings under Network & internet in the Settings app to ensure that your Wi-Fi network is set to connect automatically.
2. Wi-Fi Driver Issues: Outdated or corrupted Wi-Fi drivers can lead to connectivity issues. Make sure your Wi-Fi drivers are up to date. You can check for updates in the Device Manager.
3. Windows Updates: Occasionally, Windows updates can affect network settings. If you suspect this might be the case, check if there are any recent updates that could have caused the issue and consider rolling them back if necessary.
4. Forget and Re-add the Network: You can try forgetting the Wi-Fi network and then re-adding it. Go to Settings > Network & internet > Wi-Fi > Manage known networks, select your network, and choose Forget. After that, reconnect by entering the password again and ensure to check the option to connect automatically.
5. Power Management Settings: Sometimes, power management settings can affect network adapters. Check the properties of your Wi-Fi adapter in Device Manager and ensure that the option to allow the computer to turn off the device to save power is unchecked.

If these steps do not resolve the issue, further troubleshooting may be required to identify any underlying problems with your network settings or hardware.
