I connect to the internet just fine and Explorer never has a problem but when I try to open any program (drop box, Second Life, etc) that needs to connect to the internet it tells me there is a connectivity problem. Also, I cannot instant watch anything on Netflix because it says that silverlight isn't installed no matter how many times I uninstall and reinstall it. I tried using Firefox, Crome, and other browsers to see if it works on there but even they say they have connectivity problems. I've turned off the firewall, allowed each program individually through it and everything else I could think of but still the only thing that seems to work right is Explorer. I have found that video games like Second Life and WOW will connect if I reinstall them each time before I open them but as soon as I close them they find no connection.
