I'm stumped. My Comcast connection suddenly went. After the repair was made to the line outside the house, I could go onto the next. My Mac connects to the net wirelessly. When I attempted to connect through my secure network, it was not listed. I tried to create a new network but it kept asking for a password and when I entered the original password, it would not accept it. I tried making up other passwords, with the same results. How can I recover my old network and its settings or how can I set up a new secure network?
