My brother and I are trying to hook up our ps3 here right now. We have a problem. We have cox hi speed internet, and a motterrolla modem. We also have a red Ethernet cord. We have the Ethernet cord hooked up to the modem, we went to internet settings, entered in our Ip address, and its still saying that the Ethernet cord is not connected(not found). Its not old, or broken. We’ve had it for only about a year. Is it the cord? Or is there a step or something else that we are totally missing here?
