so i want to know if i can connect my cable modem to my xbox in one room and still have my wireless router connected to my computer in another room. thanks
No you cant do that, best soloution would be to place the router by the xbox and hard wire it to the router then wirelessly connect the computer to the router considering computer wireless cards are better value than the xbox wireless adapter.
