Rn312 (and Duo v1): Transfer speeds - manage my expectations!
This is another quesiton about transfer speeds. I am aware that there are so many variables involved in optimising these so I'm going to state my situation and hope for some broad guidance on what my...

Q1: My PC reports via the ethernet connection properties (Link Speed) that it is connected at 1.00Gbps Full Duplex. How is this so when it is running over these powerline adapators?
The trendnet adapter DOES have a gigabit ethernet connection, and that is all the PC sees. The adapter can't deliver one gigabit over the power circuit, but that is a different matter.

Both speeds are slow, and the powerline link is almost certainly the reason. The only good way to confirm that is to move the PC so you can try a test connected directy to the router.
Options include:
-trying different outlet pairs. Try to connect directly to the wall outlet and not to a power strip.
-upgrading the AV-500 adapters to the newer AV-1200 standard
-look into powerline filters. Some powerline adapters have them built in, but not all.
You could also potentially switch to 5 Ghz 802.11ac wifi, but that might not work any better (both wifi and powerline performance depend on the details of the environment).
The highest performing option is of course to install gigabit ethernet.

Thanks Stephen. That's all really useful.
The link I provided was to a TP-LINK AV500 powerline adaptor (not trendnet) and if you scroll down the amazon page to the table, you'll see the PA411KIT doesn't have a gigabit ehthernet connection.
Here's the link again in case something is going awry above.
If you agree, my Q1 is still confusing me.
In the meantime, I will try a direct connection of the PC to the router too - just to rule out the powerline upgrading issue.
I'm going to try a q4, too. On a RSYNC backup from the Duo to the RN312, can I see the speed of that backupjob in the System>Performance>Network on front view of the RN312? If so, that's showing about 3-4MBps. But as I understood it, this is a NAS to NAS backup so why is it that slow?
