Are these numbers normal, Margins seem high

Hi, can anyone look over these numbers and tell me if they are OK? Thanks for the help. Rob

Re: Are these numbers normal, Margins seem high

There is nothing wrong with the numbers per se - however given your attenuation you may want to check the numbers when connected to the test socket behind the master socket.
If this gives a reasonably higher speed it might be worth checking your internal wiring.
I assume you are into gaming hence the fast path

Re: Are these numbers normal, Margins seem high

Hi, my test socket gives these speeds.

I do play a lot of games, but also download a lot, and would prefer downloads were faster than pings, so is interleved a better chose? Cheers Rob

Re: Are these numbers normal, Margins seem high

As connecting to the test socket didn't make any real difference that probably rules out anything fundamentally wrong with your internal wiring.
I suspect, but don't know for certain, that going to interleaved may allow the BT automated systems to drop the default noise margin. However this would really mess up your pings.
Regarding downloading, if you aren't on the pro package, you are unlikely to get better speeds from the usual download sites.See this table for your product http://www.kitz.co.uk/isp/plusnet_shaping2.htm

Thanks for your help. I would use the pro package in a flash if it were not for the download limit, i would destroy that in a few days Tongue

Re: Are these numbers normal, Margins seem high

Just did a BT speed test too, is this IP profile not very low?
  Your DSL connection rate: 4096 kbps(DOWN-STREAM),  448 kbps(UP-STREAM)
    IP profile for your line is - 3000 kbps
    Actual IP throughput achieved during the test was - 907 kbps

Re: Are these numbers normal, Margins seem high

You can ignore the actual speed test result as that is often up the spout - but what do these give https://portal.plus.net/my.html?action=data_transfer_speed
http://www.mybroadbandspeed.co.uk/
In addition the fact that your IPprofile is only 3000kbps indicates that your router lost sync recently and resynched at between 3500 - 3999 kbps which is not good.
I think we need to do a bit more investigating.
First question is which router do you have
Second can you describe your internal wiring and advise where and how your router is normally connected

Re: Are these numbers normal, Margins seem high

My router is a lynksys am200, and is connected through a dir-655. It is connected to the phone system at the master socket with a ADSL v1 plate.

Re: Are these numbers normal, Margins seem high

I am moving this thread to the Broadband Speed section as that is where this type of problem usually sits.
Regarding the dir-655 I assume this is only used for the network round your house and the Linksys provides the ADSL input.
What do you mean by an ADSL v1 plate
Are there any extension sockets in the property even if they are not in use

Re: Are these numbers normal, Margins seem high

The linksys handels the adsl, the ADSL v1 faceplate is one of these http://images.google.co.uk/imgres?imgurl=http://www.telephonesuk.co.uk/images/ADSL_skt.jpg&imgrefurl...
It sits on the master socket and acts as a filter. There are serverl extentions in the house 4 with phones/sky boxs on and a few wires that seem to have been cust at some point which used to go to extensions. Thanks R Magee

Re: Are these numbers normal, Margins seem high

There are a number of things which are usually recommended for investigation one of which is the ring wire.
If you look at the inside of the faceplate how many terminals have wires attached - there should only be two
It might be worth considering a new faceplate from ADSLNation http://www.adslnation.com/products/xte2005.php as the original BT one may have deteriorated with age.

Re: Are these numbers normal, Margins seem high

Hi, it has 3 wires connected to it, a brown, green and blue wire. Should i disscounect one?

Re: Are these numbers normal, Margins seem high

Can you post a picture so we are sure but the only ones you should need are the ones to terminals 2 and 5
Are there 3 or 6 IDC connection points - this will give an indication of it's age
Once you are down to 2 wires you should go round all the other telephone points and only have the same 2 connected
Despite the fact that it shouldn't be necessary some people do recommend adding a filter to the Sky boxes as well.
