...to a router? I tried connecting my computer to my WRT54G router (which is connected to my modem, which is connected to cable) by Ethernet cable as it has multiple ports and some people in my house use wireless, however when I tried to connect using vista it required a user-name and password that it said were provided by my ISP (comcast). I naively tried my comcast.net user-name and password as well as leaving both fields blank but to no avail. What user-name and password is this talking about?
