Ethernet cable?

May be...

where do i hook up my ethernet cable for my ps3 so i could play online on my ps3

theres an ethernet port in the back of the ps3 and there should be in the back of your modem your computer is most likely connected to the internet through .but if there isnt one in the back of your modem you will have to buy an adapter .

it's in the back of your ps3 where all the plugs go should be easy to find out which one is the eithernet cables. Then after that plug it in your router.

There should be an ethernet port behind the PS3. Then you hook that ethernet cable to your source for internet connection such as a router.

It's on the back of the PS3, between the HDMI port and the Digital Audio out.

its behind the ps3 its next to the hdmi port
