...(wired connection)? I have a router downstairs with an Ethernet cable going from that to the modem into the wall. I then have a modem upstairs with an Ethernet cable going into either my pc or xbox, depending on if I go on the pc or xbox I have to change Ethernet cables to the right one. And when I switch from Pc to xbox or xbox to pc I have to reset the modem downstairs by pulling it out and putting it in again. If I got another modem, could I then plug the Xbox Ethernet cable into that so I could go on the internet on my pc and xbox at the same time? If this wouldn't work could you please tell me what would. BTW does it have to be the same modem as my other 2 modems or can it be a random modem.
