I have A Router that is almost always connected to three connections: My Toshiba Laptop, Wireless An HP Laptop Wireless A Sony Vaio Desktop Wired All run Vistas Home Premium. My problem is adding my XBox 360 to the connection. As I see it I have 3 Options: Buy Microsofts Wireless Adapter, but I fear lag online from 4 simoulntaneous conection Use A Wired Ethernet cord from one room to the next, but the cord itself might be a problem Set up another Modem near the XBox, but i wonder if there will be another 20$ a month charge just for XBox. Am I missing any options here? Thanks a lot.
