If you Google the adaptors you are thinking of, you'll be able to see the true performance figures.

What exactly are you trying to achieve?

I'm thinking of wiring Cat 6 across my place to stream HD from NAS to media players etc, though for sending HD VM signal, it'd be cheaper to use wireless HDMI (transmitting at 5Ghz).

I've got a couple of Billion 200mbs adapters, and I get 73mbs, so they seem to give decent performance.

I've got a couple of 200mbps ones, that I use to stream HD video from my server to my home-cinema room. They sync up at about 130mbps... but...

you have to have them plugged directly into a mains wall socket to get that speed. If you use an extension lead / 4-way lead, etc. on even just one end, then the speed will drop - and if you use extension leads at both ends then it'll be dire. They still work, when plugged into extension leads, it's just that they slow right down.

So - if you dont have the Powerline adaptors plugged directly into a wall socket, I'd try it and see what happens.

Yes, they are the work of the devil. Plug my router into one and then any other power socket in the house can become an ethernet port. Amazing and saves you running cable all over the place.

Cool

I plugged one of mine into a cheap POS 6 gang the other day 'cos I couldn't put the AV Adapter in to the wall socket due to some furniture, and I was surprised how little signal loss it had.

It wasn't as good as the main socket, but it was certainly good enough to stream HD video etc.

They're plugged directly into the wall socket.

I want to achieve full network capability.

If I download direct to router I get 50mb if I do it through network adapters I get 30mb.

I'm seriously considering just running a cat5e cable to the room

What sync speed are you getting? (ie if you query the Powerline adaptors directly, what speed do they say that they are synced at?)

If they're syncing slowly, then that will obviously account for the speed drop that you're seeing - but your next problem then is "What's causing the slow sync speed?" (noisy wiring, etc.)

If they're synced at a much higher speed, and hence shouldnt be throttling the download speed, then something funny is going on somewhere!

These things are serously flawed, even on the same ringmain without extension leads they have issues.
I ran cat5e round the house, not that hard in plasterboard village, and I get the full 1GIGABIT round the house.You cant get wireless or powerline anywhere near that speed.

I got the builders to wire Cat6 in our new build, it's unbeleivably quick,even flawless streaming blu-rays from my NAS.

I still use one Powerline adaptor in the bedroom though, I have it plugged in to a 4-way extension and the other end is directly connected to the wall socket. This performs fine when streaming AVI's, MKV files and standard DVDs, won'tstream fullHD but other than that it's great

If you were going to make the effort of running cables mate you should have used cat 6

Cat 5e is cheaper and more than fast enough for domestic use.

You're right, cat5e is cheaper than cat6, but when running cables in walls you should always try and future proof as much a you can.

It may be fast enough for domestic use now but in 2 or 3 years time that may not be the case. Look at historic data rates and some would suggest they can double every 18 months, anything running at 1Gb/s is really pushing cat 5e to the limits.

All I was trying to suggest was, if you'd installed cat6, you're future proofing as much as you can and you'll benefit from the reduction in signal noise, you'll see fewer retransmissions due to packet loss and you'll extend the available bandiwdth from 100MHz to 200MHz and generally see better performance.

In my old house I had cat5e structured cabling and I would suffer signal loss when streaming blu ray movies from my NAS which would result in pauses, stutters etc, in the new house, using the same movie from the same NAS, it's flawless over cat6.

When you have patch leads across a room it's very straightforward to unplug and replace with a new cable, not so when they're buried in the wall.

Anyone I know that has flood wired their house with cat5 or whatever type of cable have gone for the cheapest cable they can find - which truly is false economics.

Was asked to take a look at someone's handy work recently where a little bit of digging, showed the cable he had used was copper clad aluminium - may as well have used bell wire!!!
