What about mixing. eg x2 500mps with x2 200mps homeplugs. If a 500mps was attached to the router would this help boost the 200mps at the other end?

Sadly no, they all run at the speed of the slowest.

You can see this happening and the speeds they're getting on the PC application that comes on the CD with the plugs.

the 200av devices I had worked to 23M
the 500av devices I now have work at 40M (may be faster but I do not have faster FTTC)

The homeplug speed is the maximum theoretical throughput on the network between them. So in an ideal world, for example, if you were using 500AV plugs and downloading and uploading at the same time the maximum speed either way would be 250Mbps.

Add two more plugs and this would drop to 125Mpbs

Yep, I thought I was saying that. The third only slows the other two down if you're using it of course, many people just want connectivity in all rooms, not using them in all the rooms at the same time.

I'm using TP Link 200Mbps with my current 30Mbps Virgin connection and i get throughput over 30-35mbps no problem

hay... your electrical wiring is better than mine

I could not get more then 20->23M from the AV200 devolo's I had, no matter what I did
