I reinstalled windows on my other computer and now I can't set up the cable internet connection. The computer i'm on right now is using a network adapter to connect to my router, which is connected to my other computer. I go to network connections and click "set up new connection" I go through everything (Connect to internet>set up my connection manually>connect using broadband connection that is always on) then in the end it says broadband connections should already be configured and ready to use. But I still can't get on the internet. and nothing shows up in the network connections. What do I do?
