Whenever I try to log into Steam, it always says that it could not connect than that there is either a problem with my network or with Steam. The website reports that nothing is wrong with Steam, so I think that something is wrong with my network. Anyone know what's going on? When I plug the modem directly into my computer, it connects, but when I try to connect through the router it doesn't work. All the ports are open, and I tried DMZ.
