Well you need to list the Playstation model 1st.



For a PS2, you will need a broadband connection, and an Ethernet cord. If you have a router, even better.



For one Ethernet, just take the Ethernet from your PC, and plug it in. DONE. If you have a router, just buy another Ethernet, plug it to one port in the router and plug the ohter to the PS2.



For a PS3, the steps for the wired connection is the same, but you will have to go to settings > network and configure a new setting.



For wireless, plug in the Ethernet in the INTERNET/LAN/WAN port, and the other to your DSL/CABLE box. Then plug one to your computer. Then go to your PS3, then settings > network and configure from there.

buy the network adaptor first
