For the speed, if you have different speed in different locations, probably some locations are further away from the main powerline adapter, and have more interference, while some locations which sees better speed have less interference.

About the Utility, once you click on a device, you can see some lines goes from that device to other units and have a speed on the lines. That is the link speed between the unit you clicked and others. e.g. If there are 3 units, when you click unit 1, it will show the speed between unit 1 and unit 2, unit 1 and unit 3. If you click on unit 2, it will show the speed between unit 2 and unit 1, unit 2 and unit 3.

thanks Enson :)

logic of distance aside: is there any way to decrease objects/things that cause such line noise? two particular points on my LAN are visually close together, however I appreciate the electrical wiring may not take the same line of sight route I see.

utility: my office seems to be the primary plug (it was the first to go in) and as such I see anywhere between 200-600Mbps to the various plugs .

e.g office to living room 528Mbps, yet when I click living room the arrow reverse and I see 522Mbps for the exact same route (and all others switch to 11Mbps)

Make sure you plug directly into your wall sockets and don't use multiway adaptors or extensions leads...

It's hard to decrease the noise in powerline since we cannot really see it. You may try the FAQ from TP-Link: http://www.tp-link.com/en/faq-409.html

About the speed showing on the utility, it should be good. Since your office plug is the main plug which connect to the router, all the other plugs will talk with it. So the speed between the main plug and others is the speed which matters. When you click other plug, the utility will show you the speed between that plug and the office plug, and it will also show you the speed between that plug and the rest. but the speed between other plugs actually doesn't matter because they won't need to communicate with each other. They will all talk to the main plug connected to the router.

500 Mbit/s is a fairly solid connection rate in a real life scenario. Don't worry about those showing 11 - that's what happens when older adapters (like AV500 series) are in powersave mode.

cheers Peter, followed a number of your threads and you appear to know your TP-Link PLCs

just a little puzzled as to why you don't get anywhere near the GIGABIT emblazon across the boxes etc. I've got NO AV500 in this mix, its now just AV1300 and AV1200 only. But both listed 2 x 2MIMO (whatever that is)

Does the device connected to each adaptor play a part in the amount of speed we see in the util? e.g a CCTV camera wont show as much traffic as a WiFi Access Point/Blu Ray/Cellphone booster, perhaps?

Vogon, thanks I'm aware of that. it def makes a difference IMHO, specially if you have anti-surge, however you are sometimes left with no choice due to the size or position of the adaptor.

These NEW AV1300 adaptors are not as compact as my previous models IMHO. They have the ethernets at the top of a VERY large physical plug, which for back of telly access might be good, but they take up alot more space and also often go the opposite direction to other plugs.
They are so large that they overhang most adjacent sockets i've found....and pretty ugly IMHO.

thanks Enson, makes sense.

Hi moof, and thanks for the flowers.

Physical connection rate is not influenced by the local client device's throughput (or even the LAN line speed it supports, 10, 100 or 1000). PLC being a shared media network, there is an influence between devices as soon as total bandwidth usage becomes high. You may want to use the Quality of Service (QoS) settings in your adapters to give preference to whatever is most important to you - telephony, video/audio streaming, gaming latency, etc.

Indeed, the TP-Link 1200 and 2000 series plugs are quite large, much larger than most of the competition too. In Germany, adjacent outlets are spaced further apart, so it's kind of OK over here.

What Enson just said isn't actually true in a regular powerline network. Traffic is always directly peer to peer, not through one "main" adapter. One vendor (devolo) does have a "pro" series of PLC adapters, and their proprietary software lets you set up a single-master multiple-slave network for those cases where client devices are to be prohibited from talking to each other. Slave PLCs cannot talk to each other at all in that setup, not even through the master. [One PLC does "win" the role of the so called central coordinator - but that's just housekeeping, not traffic routing.]
