My sister has dsl service through an Actiontec wireless modem. She is wired to the modem, but I was trying to find a way to share the connection with a pc and game system that are in the same room upstairs. I have never had a wireless router, so I would like to know if they receive signals or only broadcast them? I thought they could only broadcast, but I was reading wireless how-tos and I became unsure. Edit: That was unclear. I know they receive signals but I couldn't find an answer as to whether this would work in sharing a connection. Is there anyway to set it up so I can share the connection upstairs using the wireless function of the modem to broadcast to a router upstairs, or am I stuck needing to buy a wireless card(s)?
