Surprisingly low speed - New line


[link to this post]
 
Hi all,

I have just moved home to a new build house and I got Sky to come and install a new telephone line.

My postcode is EC1V 7LP and my exchange is King's Cross, so around 1.3 Km as the crow flies.

Today I got activated for ADSL and here are my stats:
ADSL Link Downstream Upstream
Connection Speed 4093 kbps 605 kbps
Line Attenuation 52.5 dB 32.7 dB
Noise Margin 7.9 dB 15.9 dB

Looks truly appalling, although the Openreach guy who came round told me the telephone lines in my area were really bad. Also, the BT ADSL checker indicated around 4Mb for my postcode (when I checked before having a telephone number).

Is 4Mb the best I can expect with 52.5dB? Isn't 52.5dB a lot for the distance to the exchange?

Where I was living before I was on 20 down 2 up (with O2), so having a 5th of the speed is pretty depressing.

And King's Cross is not even in the list for FTTC yet, so nothing better until 2013 at least! No idea if and when they upgrade the exchange to FTTC I would be getting better speeds on Infinity either if the cabling in my area is so poor.

I'd appreciate any comments, even if only for moral support smile

Sky do start people on 4Mb but you won't see much more than that.

Some lines in London are the exception in regard to routing from the exchange and the length of cable is often much much longer than some other areas.

Some good news although not sure I can explain it...

After having the modem connected all night these are now the stats:

ADSL Link Downstream Upstream
Connection Speed 6458 kbps 945 kbps
Line Attenuation 52.5 dB 32.7 dB
Noise Margin 6.9 dB 9.3 dB

How can I have 6.5Mbps with 52.5dB attenuation? Seems like too much (not that I am complaining). Is the router misreporting this? It is the new Sagem F@st 2304N.
