I have been using the Actiontech 500Mbps Powerline ethernet Homeplug AV2 adapters (PWR511K01) for over a year now. I currently have a Premiere, Roamio Basic, and Tivo Stream. The performance and speed of the Actiontech has been good. I was never able to easily measure throughput, but with kmttg downloads, I would get about 40-50 Mbps.
I decided to try out ZyXel's Homeplug AV2, which based upon reviews seemed to have faster speeds and added a Gigabit ethernet port (but didn't expect it to do much overall for my speed above 100Mbps, given the Ethernet ports on the Premiere and Roamio Basic) I got this product and plugged it in to the same places as my previous Actiontech. The ZyXel utility (I downloaded v7.0 free from their website; ftp://ftp2.zyxel.com/PLA5215/software/PLA5215_7.0.0.zip
), showed 90-115 Mbps speeds up and down. However, when I plugged the Actiontech's back in, I got 90-101 Mbps speeds. Not much difference. (I was pleasantly surprised to see that the free ZyXel utility could measure my Actiontech adapters speeds.)
The big problem that I ran into with the ZyXel is that, unlike my Actiontech devices, it would drop the connection while I was streaming with Streambaby or transferring a file from my NAS with PyTivo. So, I returned the ZyXel but feel that all was not lost as the ZyXel utility is now helping me find the best plug combinations for internet speed with my Actiontech adapters.
At this point, though, I am just getting a 50' white Cat 6 cable and connecting my two Gigabit switches (one upstairs and one downstairs) and will just make sure that I have my speed consistently maximized. I may consider MOCA 2.0 once the devices come out if they have good performance reviews.
