A Cat 5(good) or Cat 6 (better) ethernet cable plugs into the router and the ethernet slot in the back of the PS3 for a wired internet connection.
You can use any cat 5 ethernet cable to connect the xbox 360 to the router.
You need a straight-through cable
You can not connect a DSL modem/Router to a Cable modem the are two completely different devices. Basically one speaks English the other speaks Mandarin and neither has Rosetta Stone.
a ps3 does not come with a wireless router It comes with the ability to connect to a wireless router or modem or with an ethernet cable. No other kind of internet connection to the PS3 is possible. For instance you would not be able to plug something into the USB port to use for an internet connection.
Connections between any two equipments of the same kind. For purposes of cabling, you can consider computers and routers as one kind of equipment, and switches and hubs as another kind. This aids in remembering which cable to use. So, you need a crossover cable to connect computer-computer; computer-router; router-router; hub-hub; hub-switch; switch-switch.
Ethernet cable
You need cable or DSL internet and a router connected to your modem if you also have a PC and then just connect an ethernet cable from you router to the PS2 ethernet port that looks sort of like a large phone plug
A wireless router is usually used to connect internet to your PC without wires but may be used to connect to computers together with the right kind of router.
Standard Category 5 (Cat5) networking cable will do if the length is 100 meters or less. If it will be longer, but less than around 350 meters, you'll want Category 5e (Cat5e) cable. the Kat5 is all you need, I picked up a cable at biglots for 3 bucks and works great
cross over cable
PC to Router = Ethernet Cross-OverBoth of these devices are expecting to connect to a switch. When connecting them together, we need to use a cross-over cable so that the transmit pair from 1 device, goes to the receiving pair of the other device.
