Help with my acer computer not connecting with internet

Perhaps time to re-install your Operating System. Back up all your personal data, then :-
Power computer on. Hold Alt and keep pressing F10 at the Acer logo. You may need a password. If you have used Erecovery before you would have been asked to create a password.

This should help to speed up the laptop and hopefully cure your Internet connection.
