I have a Dell Inspiron 660 that I acquired about a year or so ago. Since I've gotten it, it barely wants to connect to any sites, and even less so wants to connect when it comes to playing games on steam. It has a full wireless connection and I'm running out of options, I've disabled Firewalls, opened up all ports etc. but it still won't connect. Any suggestions on how to get this thing working so I can actually enjoy playing Steam and such again?
(Note: Every other computer in the house works just fine.)
