As the title suggests, who uses them and are you happy with the performance? Based on this Amazon review It seems that 20 to 30Mb/s throughput is the best you can expect from powerline adapters and not the N500 speed that was quoted on the model the reviewer tested. He seemed to indicate that he also tested a N750 model but that too did not show any marked improvement. My question is what good are these then? I have a 802.11n wireless extender in my bedroom and I'm only seeing 20 to 30 (mostly in the 20s), Mb/s performance. As per my other threads, I'm looking to upgrade to the AC type wireless, and extend the network, since my downstairs suffers and I want better performance for my DirectTV receiver and PS4.
