Anyone had any experience of the Homeplug technology? Particularly the latest AV. They boast, of course, up to 200 Mbps, whereas in reality I am sure if you get a third of this you will be lucky. Anyway a third is still 66Mbps which is far better than my stroppy, keeps dropping the signal, 54Mbps wireless.

I remain firmly skeptical.

I'm using the 89mb? version between my router and my main pc.

A lot more stable than my wireless and puts my xbox meter thingy up to just under HD streaming quality, so the 200mb should be good enough. The previous 56mb wireless was just capable of running standard quality streams via media centre according to the meter.

I've got the 89MB ones (supposedly).

Good news is that it does actually work. And it will work where your WiFi does not.

Bad news is that the speed of it (that I get) is something like 2Mbps. So its not the bottleneck when browsing using my pile of shite 1MB "broadband" - but shifting data about is painful.

The way forward is to install Gigabit ethernet wiring. yes

One day I'll get around to that. In the meantime the Homeplug thing is working (sort of).

Ah, I forgot to mention that I live in a new house. I can imagine that newer wiring would be essential to get good speeds?

For AV applications packet switching it isnt ideal on any width cable. For analogue signals line driving and compensating over Cat5e is probably the best option, then using multiple runs of coax slightly behind that. For digital fibre is king but still pricey and a pig to work with.

Its also down to the complexity of the wiring

yep - lots of experience here...I work on deployments for service providers (IPTV etc) across EMEA

Without going into technicalities I much prefer the DS2 based 200Mbps products, rather than the Homeplug ones.

With 4 of them on a home network you can get about 140Mbps aggregate bandwidth.

The protocol overhead is still very high (worse than 802.11) - thats what happens when you wrap your data up, add error correction, AES encryption etc...just the same as wi-fi...its actually putting data on the wire at 200Mbps (at best) but the throughput you see as an end user is about 1/3rd to 1/2 of that due to the overhead.

Its a good technology as a compliment to wireless, or for bigger houses.

You can get the Powerline plugs with built in 10/100 switches, and even access points - which are very useful to get wireless into a remote room in the house.

Tell me if this would work.

At the front of the house is a netgear DG834G wireless ADSL router, this is plugged into the phone line for adsl connection and then throws out a wifi signal so that other computers can connect to it. 100ft away, in the back garden, from the router is a log cabin. i can pick up a weak signal with a usb wifi adaptor that likes to drop out and a ok connection with a HawkingTechnology mini dish. I have a 50m long power cable at 10mm wide running from the power box in the garage into the cabin fuse box (capable of carrying up to 10Kw in energy).
If i was to plug a cat 5 patch cable from the router in the front room and run the patch to a Devolo AV plug in a 4 way power strip, could i then plug the other AV plug into a socket in the cabin and then have a cat 5 cable run out of the AV plug into switch so that more than one computer can be patched into the switch to have internet access? So i don't have to rely on a weak signal strength?
hope this makes sense.

yes it would work, with a few exceptions

Unless you already have a Devolo (Intellon based) then Id buy a pair of DS2 based ones - NETGEAR HDX101 jobbies.

Never plug Powerline sockets into a powerstrip - you will lose a lot of performance (sometimes dont work at all with filtered power strips) - plug them direct into the wall socket

if you can wait a month or 2 we are working on a powerline ethernet adapter with built in powersupply for a DG834G so that you only need to use one wall socket...should be a very tidy solution

Neat. What I want is an ADSL router, with 4 ethernet ports, WiFi and mains networking all in the one box. Nice.

would like the idea on just the one plug. My only problem is that there are evry few sockets in the house and i have power strips all over the place. Just havn't had time to put sockets in the wall. Actully would probably be better to run CAT5 from the router, around the room to a power socket on the far wall with the plug in there.

that would be very expensive though...which is why you will see it as an option on some ADSL wi-fi routers built into the powersupply - its more flexible way of doing it and you dont need to buy a new router

I see...with an ethernet cable going from the router to the power supply...possibly in an "integrated" cable or some such arrangement?

I'm using the 200 Mbps ones at the moment while waiting to get ethernet wiring finished at home. It works, but transfers are very slow.

So 200Mbps doesn't actually mean 200Mbps then? Do you know what throughput you are getting?

no - due to protocol overhead (like wi-fi) - in tests with 4 x 200Mbps adapters on the home network I see 40-50Mbps of real IP layer throughput with a 180-200Mbps physical layer link

yes - exactly like that - a power brick, with 3 integrated cables - 1 for mains, 1 x ethernet, 1 x 12vDC1A for router
