Do Sky always turn your speed down...

Not quite sure why you are seeing such poor results.

You could try posting the stats from the test socket and see if any better, or as previously said, you could be on DLM or even capped.

How to test your ADSL in the Master Socket

In reality your attenuation is not far off mine, and I am currently at 6meg and normally get approx 7 meg

I did try my connection with the main socket faceplate off & with different filters but was the same. I'll try it again & post the results up.....

Could these increases in attenuation have anything to do with the fact that Sky is moving from DSLAMs to MSANs to provide those with Sky Talk line rental with the service over their PSTN network and not via BT Wholesale Line Rental?

I hear that Tie Pairs inside exchanges linking LLU equiptment to the MDF can be very long, several hundred meters in fact. The Exeter telephone exchange, for example, has multiple MDFs and is five stories tall so if Sky install their MSANs on the top floor and the MDF feeding my line is in the basement, then the Tie Pairs coud theoretically be very long indeed; adding attenution.

Also some LLU providers have to put their equiptment in a seperate building depending on exchange capacity, with tie pairs from the "sub exchange" to the BT Exchange travelling an indeterminate length underground between MSAN and MDF.

Obviously since Easynet have had their LLU kit in most exchanges for a long time (I know they were only the 2nd LLU provider in Exeter) the original equiptment could have been very close to the MDF. Now that they have to install new equiptment to support their PSTN network, after most of the LLU providers have done their thing (e.g. Bulldog, Tiscali, Orange, and Be* have put their equiptment in WWEXTR since it was originally unbundled by Easynet) this would probably be much further fom the MDF than the original Easynet DSLAMs.....

Just a theory at the moment, am I thinking along the right tracks?

Well, i left it until today & rang Sky again, customer service girl kept going through the same old pull this out, push this in, change filter, unscrew socket cover etc even though i kept telling her all this was done & just to uncap my download speed. In the end i gave up in frustration & hung up on her.
Half an hour later this was my stats....
ADSL Link Downstream Upstream
Connection Speed 2048 kbps 416 kbps
Line Attenuation 53.0 db 31.5 db
Noise Margin 9.6 db 24.0 db

So she got there in the end, lets see how long it stays this way............

I don't think you were capped. You were previously on ADSL2+ but your line was so bad it could not handle it. You have now been put on G.DMT which works better on noisy lines. If you consider upgrading you will have to sort out the noise problems as the way things stand, you would get very little more speed. You should be able to get 4-5 Mb quite easily with your attenuation, but your noise margin shows you will get nothing like that.

Cheers for the info, if i can just keep getting 2048 kbps i'll be more than pleased. At some stage i'll maybe try a new socket faceplate with built-in filter to see if that helps with the noise.........

[Bribrian]

So what should my optimum noise level be... today it's...
Noise Margin 7.1 db 24.0 db

Should i be looking at higher or lower figures..........

[Isitme]

The higher the noise margin figure, the more stable your connection will be. As the figure rises, so the potential for more speed goes up. The default figure is around 7dbs, anything much less than that and the connection is liable to drop. Anything much higher indicates your line is capable of more speed.
