Ok guys here goes..

After struggling with a poor set of ADSL line stats I sought to find a practical solution to improve my downstream noise margin (SNR), thusly improving my chances of getting a speed regrade. I tried every suggestion (here), and including those found via Google, and finally came to one which improved it by 3dB :cool:

You may be thinking "3dB... so what?" but for some like me it means the difference between breaking a restriction and getting better net speeds.

I followed the guide over at ADSLguides where it talks about how removing the 3 ring from the socket can essentially give you a nicer line with less interference. I took the plunge and proceeded to remove the 3 ring wire from my filtered master socket as per the guide and then logged back on to the modem through the configuration page.

This seemingly was all that was needed, as I went from 12dB to 15dB noise margin!! I urge anyone wanting to squeeze the last bit of signal out to try this!!!

UPDATED: Full guide can be found: HERE

Thanks for the time,

EVH

Cutting the green wire (I'm assuming this was the ring wire) from my cheapo filters and removing the 15m phone extension boosted my SNR nicely, gained a fair few dB SNR on 2meg when I removed the ring wire and about 1000kbps on MaxDSL when I removed the extension.

Are you going to try and get a regrade to an IPStream2000 based service or go for MaxDSL?

I think it'd have to be MaxDSL. You can improve SNR all you like, but the attenuation limit is still ~42dB for IPStream2000.
 
I cant seem to find this guide on Adsl guide, have you a more specific link?

Mine looks like this...

How does this work? as you see my niose margin is @ 11db is higher better?

and do you mean a wire in the microfilter? or the box on the wall?

Higher SNR is better. You have 11dB, which should mean your line is perfectly stable. I wouldn't bother messing about with it, as your sync rate can't increase any further than that.
 
To elaborate a bit more.. I have a filtertered master socket, and all I did was pull out the orange wires in Terminal 3, and the SNR was improved :cool:
