It is a measured value and as such can't be changed unless you move house

Internal wiring can affect the line quality, as can faulty line filters.
To find out if your internal wiring is causing issues, try plugging your router directly into the test socket on the NTE5 master socket... this is the removal section which will isolate any internal connections. If you sync rate is better and line attenuation is lower then you need to investigate the quality and termination of your internal wiring. One option is to remove the ring wire.

As Peter said, bad wiring can cause high attenuation. Even a dodgy router can too. Also, you say you are using an extension. Can you plug into the test socket and see what you get there?

Quote The phone company have upgraded my area to 21CN and it looks like they have put in more exchanges. They have put one on the end of my road about 100 metres away (original one was about 4-500 metres away)
I take it you are not in the least Tech minded?
by exchange do you mean the green box? that is only a junction box, the exchange is that big brick/concrete building, also is the new Green thing taller that the other two and has it got slatted panels on the front door?
enter your info on this page and it will show you where your exchange is from your house http://www.kitz.co.uk/adsl/adslchecker.php

Quote When I wired up my extension I used the Blue, Blue and White, White, White and Blue wires. So should I just use the Blue wire and the White wire ?
You should only use 2 wires. Terminals 2 & 5 are the only ones needed, wiring the others will cause additional noise to be picked up by the extension wiring.
Superusers are not staff, but they do have a direct line of communication into the business in order to raise issues, concerns and feedback from the community.

Once it's on the new technology it will resync as high as it can go.

Although you can see the sync at a higher rate now the order is still not completed so it may not settle to your new speed until tomorrow.

Because your topic is about attenuation I have question to tech gurus reading it :
If James line with his attenuation (Attenuation(dB)114/205) sync at high speed (Data rate(Kbps)13335/440) what speed should be on my line if mine is as shown below :
DSL Type: G.992.5 annex A
Maximum Bandwidth (Up/Down) [kbps/kbps]: 23,140 / 14,404
Bandwidth (Up/Down) [kbps/kbps]: 446 / 14,062
Output Power (Up/Down) [dBm]: 12.5 / 18.5
Line Attenuation (Up/Down) [dB]: 3.0 / 4.5
SN Margin (Up/Down) [dB]: 28.0 / 14.5
I'm curious because with 3.0dB UP and 4.5dB Down it should almost reach maximum of ADSL2+ speed or am I wrong? (funny that with low attenuation -short line- I have so low speeds).
I already asked question but till now I'm still not satisfied with answers - and here are my old statistics - https://picasaweb.google.com/s.polomka/Connection?authkey=Gv1sRgCJLO4fe7j9LSsAE# (taken on Netgear DG834)
