I switched from using Powerline adapters to using MOCA adapters and become much happier. I tried at least 4 different pairs of Powerline adapters two of which are AV2 with Gig-E port rated to 600Mbps. The Powerline adapters worked well enough for the (relatively) low bandwidth requirements of watching Tablo since these Powerline adapters (in my environment) consistently yield at least 25% packet loss. With 25% packet loss these Powerline adapters cannot support streaming a very high quality 1080p concert from my NAS without hiccup. The MOCA adapters are a litter more expensive than the AV2 Powerline adapters but they give me 0% packet loss with 100 Mbps speed that support my other video streaming requirements without any issue.
So I will say that if Powerline doesn’t give you the performance you need, then MOCA is the way to go. I also carry OTA signal on the same cable without any problem. I can network up to 16 MOCA together not that I needed more than 2 to service the area where Powerline adapter fails.
And consider yourself lucky if Powerline works for you but check to see if you have any packet loss. The simplest way to check for packet loss is to ping the device IP address behind the Powerline adapter continuously for about 4-5 hours and see what (if any) packet loss you have.
