This is on both of my computers. I have a wireless router, one desktop is plugged directly into the router, and my desktop recieves the signal, on the other side of the house. Anyway, both computers won't connect to anything live, meaning things such as live games and chatrooms. It comes up with four errors when I try, 1. behind a firewall, 2. stale cashe, 3. not connected to the internet, 4. (not sure what the other one was), (this is on yahoo games, such as checkers, chess, .......). I updated the JAVA to see if that was the problem but it wasn't. I have McAfee Firewall, which I shut off to see if that was the problem, nope, still didn't work. I made sure that the windows firewall was not on.
I was told that there is a firewall on the router, but I don't want to shut that off, maybe there is a way to get around that problem.
Last night I was told to go onto microsoft website and try their techsupport, they couldn't even connect to mycomputer when they have to see the system config. It's like I can get out on my computer, but nothing comes in.
These things did work before, but don't work now. Our IP's didn't change, nothing is new on our computers, accept maybe windows update. We don't have our router system set up as a network.
Aol Instant messenger, yahoo IM, weather channel updates, they all work.
A program called Steam(for games), Limewire, don't work aswell.
