Can't get WiFi to work all of a sudden

Is your router unplugged or did power to it cut out? Your solution may be as simple as restarting your router or plugging it back in. Is your device trying to connect to a different Wi-Fi network? Although your device typically connects right to your home Wi-Fi network, it may be trying to connect to a different network. You might have to manually make it connect to your home network and forget the other one. Did your Wi-Fi password change recently? You may need to reenter the new password in your device if it didn’t automatically save the changed passkey. Are other websites or internet browsers working? Sometimes, certain websites or servers go down. Check other sites or use another web browser to verify whether it’s your Wi-Fi or just a specific site. Can you connect if you move your device closer to your router? If you normally have a strong signal in rooms far away from your router but suddenly can’t connect, take your device closer to your router. If it can pick up a signal in a closer room, you may have a long-range signal issue, not a Wi-Fi connection problem.
