I am now have 4 adapters from the AV500 range; two with power sockets and two without.

This means that when I plug the laptop into one of the adapers I see 3 "Remote Devices".

All the device names and MAC addresses are fine but I only seem to get one valid "rate".

Typically I would see:
Device 1 ..... 200 Mbps (typical speed - can vary)
Device 2 ...... 11 Mbs (stuck at 11 Mbps)
Device 3 ...... 11 Mbs (stuck at 11 Mbps)

And sometimes:
Device 1 ..... 200 Mbps (typical speed - can vary)
Device 2 ...... ? (just a question mark)
Device 3 ...... ? (just a question mark)

The above is when the laptop is plugged into an adapter that is remote from the adapter that is connected to the router; and "Device 1" is the adapter connected to the router.

If I unplug the laptop from the remote adapter and take it to the router and remove the router adapter's connection to the router and plug the laptop into that adapter instead (ie into "Device 1") then I get speed values for all 3 "Remote Devices".

Questions:
1. What makes "Device 1" so special?
2. Why can't I get speed rates for all devices when I connect to *any* adapter??

This gives me the impression that connections between, say, device 2 and device 3 will be really slow.

(In my network it's not just about the internet connection. I have a music device that needs to connect to a NAS drive without needing to go via the internet)

Please help me understand how the powerline topology works and please reassure me that speed between adapters is just as good as between adapters and the internet.

Thanks.
