...is generally limited to about 100 meters (approx. 300 ft.). Lengths long enough to reach across the room are available at almost any computer store.

This might sound like a stupid question but I recently got a liksys router and want to hook up my computer and playstation 2 to a cable modem. I already have my computer and home phone linked but my mplaystation is on the other side of the room. I have an extra ethernet cable, but it is not long enough to reach. My question is how long of an ethernet cable can I buy and does anyone know a good place to buy them? thank you
