I just got a new computer thats running windows 7 home and I was working on it. A box popped up and asked me if I wanted to allow or block some program I didnt know and didnt activate. So I blocked it. next thing I know I am connected to my router but cannot access the internet. My other computers have no problem connecting wirelessly. Makes me think I managed to block my wifi program (whatever that is). Does anyone know how to unblock that or what it would look like?
