Slow internet - strange noise margin stats

Apologies for another of these.

My modem has synced at 8mbps, on a good day I get 2mbps, normally 1.5mbps, but when things get busy in the evenings:

Edit: 1:30 pm on a Thursday

Modem reports this:

There is a truck load of bad cable in the house which I need to sort out but
- would that be the reason for upstream noise to be so high?
- is the downstream noise "normal"?
- why the large differential?

I'm connected to the master socket, but the internal wiring to the socket is a mess of crushed/kinked cable - over the coming weeks I plan to shorten everything and replace the face plates with decent ones.

It's good to know I *should* get fast speeds, so I've something to aim for. Thanks

I live opposite the telephone exchange.

Apologies for the confusion though, it appears my exchange is only enabled with "20CN ADSL". With my details entered, the ADSL24 package selector says I can only get up to 8Mbps - so you were right, no ADSL2+

This weekend I'll sort out the phone cabling in the house and follow your advice. I'll let you know how it goes

For information though:
Modem: Netgear DM111 ADSL2+
Router: Linksys WRT54G/GL/GS (firmware: DD-WRT v24-sp1 (07/27/08) micro)
ISP: ADSL24 - Home30 package

just to clarify, have you tried it in the test socket as well ?

Ah, no I haven't - forgot about that, I'll unplug everything and give that a try

Reading through my ISPs FAQ it may be a stuck profile at the exchange.

I'll work through the things they suggest and see how I go

ADSL24 claim not to shape or throttle, but from what Tealc says someone else might be limiting me as it's not an LLU line? I guess that would explain the dip.

This is my exchange btw: http://www.samknows.com/broadband/exchange/SLHLY

I don't have many options for new ISPs - BT and TalkTalk

I just checked the exchange and BT is reporting no VP issues, so it's looking even more likely to be an ISP issue.

What's a VP issue?

Thanks

http://speedtester.bt.com/ has given me this:

Code:

Download speed achieved during the test was - 928 Kbps
 For your connection, the acceptable range of speeds is 400-2000 Kbps.
 Additional Information:
 Your DSL Connection Rate :8128 Kbps(DOWN-STREAM), 448 Kbps(UP-STREAM)
 IP Profile for your line is - 2000 Kbps

Looks like my profile is wrong - is that something easily fixed by my ISP (do they manually set it or is it auto?)

I've raised a support ticket with ADSL24 regarding this
