First of all, how old are you?
Who manages the WiFi at home?
If you’re old enough to have your own WiFi and not living with your parents because you’re underage, then simply try restarting the home WiFi. Unplug it and then plug it back in the outlet to see if that helps.
If not, contact your internet provider for extra assistance.
If you’re underage, ask your parents for permission to get on internet.
