Great tip this instantly fixed my issue and now I sync at the highest speed possible.
This trick DOES work! We have 3 phone sockets in our house. I identified the master socket and removed the wire from
the number 3 terminal, rebooted the router and checked my line stats.
Downsteam SNR increased from 30.0 to 33.0 and attenuation reduced from 20.5 to 19.5!!
This tip really works.I improved my conection from 5.6 MB to 5.9 by removing the orange wires from 3 and 4
Interesting tip! However, beware that if you have the old-stle BT Master Socket as described, its strictly against the rules to fiddle with it, so put things back if you need to call out BT at all!
If you explain the situation to them, BT might well come out for free and fit the NTE-5 master - this makes life easier for them as they can then get you to disconnect all your extension (and ADSL) wiring easily when fault-finding. I can recommend the filtered faceplates - also from www.clarity.it.
The 'ADSL Faceplate' is actually called an NTE2000.
They are really good. I have one fitted in my home at the moment. They definitely improve the signal to noise ration.
If you have 8 meg ADSL, but live too far from the exchange, they make a big difference. One thing that can improve matters is synching your router at night - i.e. turn it off and then on again at 2 AM on the weekend. The router will hopefully synch at a higher speed than normal.
This does actually work people, my ADSL Max was syncing at 2.5mbps now it's at 4.5mbps! an extra 2mbps! It's really worth it, just make sure you put the wires back if you move.
This worked for me too, an extra 1.5MB on my sinc rate.
Cheers!!
Great tip. I removed ring wire from all extentions and back of master socket. Downstream sync rate increased from 4.16Mbps to 5.37Mbps with same SNR, which is nearly as much I got connected directly to the test socket (5.9Mbps).
Connecting the router directly to the master with/without a filtered face place is impractical for me due its location and no accessible power socket nearby. So this was the best solution for me.
The long extention line (put in by previous owners) to upstairs around the outside of the house and back in through the loft seem to have been acting as a nice MW aerial 
Many Thanks
Thanks...Have recently been upgraded from 2 meg to 6 meg by Orange and when connected the snr margin was 6....not really enough....frequent disconnections were happening and when disconnected the snr margin was -1.5!,Chopped the ring wire and got instant reconnection with an snr margin of 17!.....Thanks

Thanks Phil! I've had no adsl for over three weeks, was unable to get sync, or at best was getting intermittent sync.
After asking about for help somebody pointed out that my SNR of 3.3 was extremely low and was the probable cause of the problem.
Did some searching on how to improve SNR and found your page. Disconnected the ring wire and my SNR has shot up to 18.4, and increase of 15.1. I'm amazed.
This worked for me; except both the orange and the orange/white wire were connected to terminal 3. I removed both and whilst the downstream db rate is on 11, it's rock solid on 11 and doesnt show any signs of dropping any further, which is good enugh for me for now!
Thanks.
Brilliant tip. My master socket only had 3 wires connected and one was the orange one to pin 3.
I was syncing at 1088 kbps before, took out the orange wire, now at 2528 kbps, no change in any other stats which doesnt bother me, just hope my profile gets updated in a timely fashion!
Thanks for the tip!!!
Top Tip Phil many thanks, I was getting 3.5 to 4.8 meg now I am getting 6.9, told my mate and he is now getting 7.0 meg cheers
this tip doesn't work for my ADSL, removed the orange and didn't do anything and i don't use filters either, my SNR Margin DS is 31. strange huh.
stumbled accross your page, very interesting and although you are more technical than me, i confirm these findings over the last year or so. i dont know about data so found this out by unmeasured experiments.
re entered homepage
Can you believe it... I did this to all four phone points in my house and it made no difference what-so-ever! How come?
Why didn't it make a difference ? firstly you can only fix something that is broken, so if there was no interference affecting your connection you couldn't get rid of it.
Secondly a fixed speed product or one operating at its maximum speed would only show a change to the noise margin.
Finally if you have a very high noise margin to start with you may find that 31 or 31.5 dB is the maximum value reported so increasing it from a real value of 40 to 42 doesn't change the reported number.
Lo I'm on 8Mb ADSL max and during the day get a noise margin of 11-12. During the evening i get disconnects as it drops to 7-8 
I have one extension from the master socket which then splits to my PC upstairs and the phone downstairs. I have removed the orange wires from the phone and PC ends. Doesn't seem to made a difference to the noise margin. Does it have to be at the master socket? Mine doesn't look like yours picture - i believe it was designed for home extensions. I have no slack between where master socket and the cable splitting box, so i don't want to mess it up...
(My phone extenion wire btw only has a blue pair and an orange pair. seem to be fine with just blue pair attached...)
With MaxDSL you won't see the CNR margin change but you should see the speed go up if removing the ring wire reduces the noise. As always you can't remove interference you don't have. Useful if you discuss margin along with attenuation and modem line/sync speed.
A master socket should have external telephone 2 wire in but 6 wire out.
This days telephone system starts at the main socket subsequent sockets will have 6 wire cable in six wire cable out.
The system you demonstrate would appear
to be an incorrect star type system hence your problem with noise.
Extra thinks The photographed master socket is obsolete type.
More wires can be used on a B.T. home hub,the extra socket for phone can have a two wire connected use your obsolete sockets without the capacitor to provide a complete new home telephone system,use home hub phones any dec phones if all are tuned bells or music it is a magnificent sound and the ADSL still gives a good speed.
Hello, forgot to check back... My stats as I type are upstream data channel rate 448Kbps and downstream 7616Kbps.
UPSTREAM Noise margin 23dB Power output 12dBm Attennation 11dB
DOWNSTREAM noise margin 12.5dB Power output 20dBm Attenuation 18dB.
In the evenings the downstream noise margin can go to 9dB, and I lose sync
I just wanted to know whether undoing the ring wires at the phone/PC end has the same effect as taking them out at the master. Anyway it doesn't seem to effect mine. Incidentally... only the blue wires are now attached in the boxes where I plug in the modem/router and the phone.
Why is the way I have done the extension wrong? I used a proper junction box. Would be interested to know 
Thanks for your advice
Todays system says that a 4 wire should come from telephone pole or underground.
2 wire attached to socket one 2 b wire and 5 a wire.
That box has a resistor and capacitor plus a gas discharge tube electric transient eg lightning.
depending on which 6 wire cable is used it is best to follow the tags on each socket.
pin 1 spare,pin4 spare, pin6 spare.
pin 2 and pin5 takes speech.
pin 3 is the mid point of the capacitor and resistor is bell wire also exchange test for phone in or out.
Standard wire is designed to balance out noise pick up.
Only one socket is allowed to have any resistors or capacitors.
The cable must be from start then to next socket then to next etc.
I'm glad I found this neat tip, it certainly works for me, downstream has gone from 208 kbps to 2750 kbps !! Well done !!!
One of the best tips in years. I'm still on BT Broadband Basic. They put me on at 2Mb in early 2005 - kept dropping out, and after 3 months they downgraded it to 1Mb and refunded 3 months payments. Even at 1Mb it's not brilliant - I'm a long way from the exchange and have 43 dB line attenuation. Using your trick increased SNR Margin by around 6 dB. Seems much better, and the modem can use many HF bins. Many thanks - gr8.
I wish my ISP had pointed to this page!
have a look at: http://www.dougrice.plus.com/Erl...rlangs/
adsl.htm
I have put a spectrogram of the results of ADSL SHOW CHANNEL obtained fron my Solwise 715 ADSL router. I have Perl and TeraTerm scripts to poll the ADSL modem each time I turned on my PC and when I wanted. This was collected over a period of a year.
I blagged a master socket off an Openreach engineer on my way home on Friady. There was an inductor in series with the bell wire. This "disconnects" it at high frequencies.
