I am connected to the internet but can't get on line. It says there is a problem with HTTP port (80). HTTPS port (443) and FTP port (21). It is a desk top computer, but the lap top (which I am currently on) I can use to get online. They are connected to the same thing so I don't know what to do. Please help! Thanks
