Powerline Speeds

[ruddock08]

Hi all,

So have got a pair of 500mbps Powerline adapters in anticipation for BT Infinity install.

The adapters sync at 337mbps according to the utility, yet I am still only getting around 25mbps from the actual port??

Is this your first pair of powerline adapters? What is or are the make and model number(s)? These speeds are being achieved via VM? Are direct connections to your broadband connection hard wired achieving better speeds?

What is your broadband speed? If you are on adsl, 25mbs sounds about right

I'd do some quick tests first:

1: Try both adaptors plugged in to the same (non surge protected) power strip and see what the speed is

2: Make sure the powerline units aren't on surge protected power strips, and are, if possible, on the same ring main (my own powerline setup ran at half speed when the units were on separate circuits)

Not the first pair I've used.. but the only pair I have plugged in.

Model number is: TP-LINK TL-PA411 (500mbps)

Yes these are connected straight to my router. Hard wired router speeds around 156mbps. Highest I can achieve on PL is 22mbps. I have tried upstairs-downstairs (changing the PL from plugged in next to router to plug socket opposite side of room), also tried adjacent room from router and lastly the same room as the router, and still can only achieve 22mbps TOPS.

Very annoying. I only need it to achieve 35mbps so that I don't have to pay to get an ethernet line installed from upstairs-downstairs for BT Infinity

Pretty sure ADSL tops out at around 17mbps. I'm with VM 150mbps.

Done both of these now. Doesn't make a difference

I have done a speedtest using the PC that's on the top floor and connected by the same tp-link powerline adapters to the router on the floor below. I get a speed of about 55Mbps. One powerline is on a non surge protected power strip and the other is plugged directly in. You should therefore be able to get more than you are getting. It sounds that perhaps you have a very bad mains supply.

60meg is normal for homeplugs, ive never seen one go faster

Annoyingly I think you may be right...

The bottleneck is within the upstairs office somewhere. Weirdly enough, the electrics in there are only a few years old. Guess it's going to have to be Ethernet cabling

I only need 40!

Is the upstairs/office space on a separate ring main/circuit breaker to where the router is?

I'm never certain what affect that has. The PC upstairs is on a separate ring that just serves that room (Its the only room up there) if fact each floor is a separate ring each with its own circuit breaker but only one RCD for all the power circuit rings. Our rewiring was done about 10 years ago.

It means longer distance and more attenuation for the signal to travel through which means weaker signal.

Upstairs is on a separate ring to downstairs - yes.

But as I say, this doesn't seem to affect it. 22mbps seems to be the limit even within the same room.. Strange

It might be worth repeating the "pairing" procedure with both units, and also triple checking the cat5 cable you've been using, as unless you have the noisiest mains wiring in history, you should be getting more than 22mbit.

My house has most sockets on one ring main, but I've had an extra socket added using a previously unused 16A breaker. With both powerline units on the same ring I get a much better speed than having one unit on the ring main and the other on the new socket.

There is one difference between Ruddock and myself in that I also run a second pair of powerline units which connect a Logitech security camera in the garden to the router. There was confusion when the tp-link was added and I had to put a password on the Logitech ones. But they only seem to run at about 16Kbits/sec

[progers]

I have the same TP links and get about 45Mb (I'm on 50Mb)
The router end is in a 5 way protected power strip and the downstairs one in a standard 6 way strip. They are on different rings so I think you should be getting higher speeds.
