In reply to a post by XRaySpeX:

the NM is already as low as 6 db, the default level at which the previous estimates applied, and you are only getting 10 Meg, Would expect NM to be much higher at this stage.

I don't agree. The noise margin is correct. It is the sync speed that is far too low, indicating a serious wiring issue.

Reverse sides of same coin

Agree OP has a wiring issue.

The noise margin is as per a DSLAM setting. The sync speed is negotiated based on a number of factors, as you well know.

The only way the noise margin gets high on a BT Wholesale system is by setting or by sync capping. (Barring the temporary effects of connection during a noise burst). None of these are evident. They are emphatically not two sides of the same coin.

Thanks for the comments guys.

Unfortunately, due to how the telephone line is delivered to me in my room, it leaves almost no chance of it being altered in anyway. Unless there is something the ISP can do (freeola) then what i am getting now seems like what i am getting now is what i am going to have to live with.

Ill call m ISP in the morning and see what they say, but i am not going to hold my breath for much improvement.

OK, how do you know NM was not set high enough to result in 10 Meg sync and has since drifted down to 6 dB due to excessive noise on line?

I know from my own experience that BTw do operate some sort of stabilisation period and successively set the NM target to 15, 12, 9, 6, 3 dB, usually with a re-sync once per day,

Because of the ADSL(1) stats posted earlier in conjunction with all the rest of the evidence we have seen.

Enough!

In reply to a post by akwilliams:

As promised (and a lot sooner than i anticipated) my broadband has gone live. These are the figures after about 30mins of being live:

ADSL Link Downstream Upstream
Connection Speed 10067 kbps 1123 kbps
Line Attenuation 23.5 db 10.3 db
Noise Margin 5.9 db 5.8 db


Now, from my understanding, although at the moment these figures do not look particularly good, the line is in "training" mode? Which i believe is for the next 10 days or so?? And it should steadily increase over this time if i have read right.

What do you guys reckon?

Not very good.

I'll suggest powering off the modem/router overnight and then, immediately after you've powered it back on, note the statistics. A full hardware reset at your end and allowing the DSLAM to "recover" without any device sync'd with it may prove to be beneficial.

As for "training mode", I'll use the phrase "hog wash"!

Edited to add: Where are you located? (If you're in my home town, then the grumpy old black cat could possibly visit. )

Well,

I powered off over night and connected again this morning... It resynced at 12079 which is quite a fair bit better.

Gave Freeola a quick call, they said just leave it alone for the next 10 days. Nothing more nothing less. The connection will do what it needs to do in order to give the best possible line speed.

Router rebooted about an hour after i turned it on and resynced at 11309.. I am now not going to fiddle with it and see what happens. As said, the structured cabling to my room is totally out of my control. Its CAT5 from the wall socket back to where it connects through the switchs and eventually to the BT distribution point.

@ burakkucat - I'm located in Corsham, Wiltshire!

I'm not sure about BT Wholesale but I know that Sky's DLM alters the ADSL power output which can affect synch speed. Can you pull that figure from the router?

Sync speed not very useful w/out NM.
