hi i have a cable modem connected to a wireless router hard-wired to two seperate ps3's. I am looking to get the optimum connection speeds out of my ps3. i have been told to use a switch instead of my router. i also want wireless in my house as well. can i hook up like this? ; modem switch (ps3 ps3 router)? if i connect my modem directly to one ps3 my ps3 will not find an ip address will this problem remain if i go through the switch or will it find an ip address? will this optimise my connection? will my connection be better if when not in use i unplug the thernet cable going to the wireless router from the switch? is there any other way to optimise my connection speed on my ps3?
