I am considering purchasing the Netgear XAVB5004 4-port powerline kit for use with my home theater setup, which has several devices that need reliable internet connections (PS3, Apple TV, Mac Mini, TV). While I was researching the product, I saw that the 4 ports in the back are rated different speeds (priorities?) -- one high, one medium, and two low. I don't want to sacrifice speed on any one device. Am I misunderstanding the purpose of the different ports? Or, am I better off just using a one-port Powerline and plugging that into a 4-port ethernet switch for equal bandwidth distribution to each of my devices?
