I wonder if the new Homeplug AV2 will make a lot of difference in comparison with the existing 500Mbps adapters or will just be another 1000Mbps nominal and 45Mbps real ? My Linksys 200Mbps Powerline network goes from 10 to 30 Mbps real speed and I need at least 50 to 70Mbps to be able to stream Bluray movies. Should I wait or should I try something like the Zyxel 500Mbps ? Thanks.
