Strangest internet

Actually I am mad. My interenet worked perfectly until they said "Repairing Internet near your location". Since then I need to wait 1 hour to browse internet again, after I came from school because he sayd I will have internet but actually I didn't have. What I am trying to say is that I have internet but cannot access it. Youtube and FB works during downtime what is strange. Strange because he sayd that I dont' have internet. Idk does somebody have a solution for this? It has an X between multiple and Internet during downtime. Thanks for reading!

My internet was really shitty too 3 days ago, Are you using comcast?
