Yea I know about the 5 port but that would leave me with no spare ports.
Right now I am using a old 10/100 router from vonage plugged into the dlink router to add the extra ports needed.
So it gets irritating going from gigabit to 10/100 and I still need one more port. So I have to play Green Acres sometimes to switch cables.
In fact you will love this from another thread.
My PS3 I found that the wifi connection will not support streaming Blu ray connections properly due to the bit rate but hardwired it will. Even though both are 10/100 adapters in the PS3 but my wifi router is N.
