Plug into hidden test socket, remove ring wire, swap filters ... ?

I already did all that, everything is all fine.

When i was with Zen i would find speeds dropping during peak times to anywhere between 2.1mbp/s to 4mbp/s, on a few occasions it dropped to 0.8mbp/s, of course that was using the BT network.

I am happy with a constant 5.7mbp/s during peak times and happy to see higher upload speeds too, i am just wondering where do you get the 11mbp/s speed from, Talk Talk quoted me around 8.9mbp/s for downloads.

Put 36 (your attenuation) in here: http://www.kitz.co.uk/adsl/max_speed_calc.php

It says the line length is 2.6km, i assume that Talk Talk are using my local exchange and i know i am approx 1 mile from that. I suppose the 2.6km could represent how the wires get to me as opposed the straight distance i am from the exchange.

I also know attentuation when on the BT Network with Zen was 42db, now it says 36db.

I will take a closer look at the router, perhaps its a setting in there that needs changed.

Latest figures in the Router Status show:

ADSL Link Downstream Upstream
Connection Speed 7014 Kbps 961 Kbps
Line Attenuation 35.9 dB 15.9 dB
Noise Margin 12.4 dB 12.7 dB

Ping time is 47ms, with Zen it was typically around 84ms, so thats an improvement.

A test at another site shows this.

Download speed 6001 Kbps
Upload speed 780 Kbps
D/load COS 99 %
U/load COS 72 %
RTT 5 ms
RTT Consistency 13 %
Max Delay 37 ms
Avg Delay 4 ms
Max Bandwidth 6001 Kbps
Route Speed 104856 Kbps
Forced Idle 0 %
Route Conc 1.0

your noise margin is set artificially high, but they might not want to change it for the first (10?) days. A noise margin of 6dB should give you a few extra mbits

These are my latest figures, i have tried a direct connection to the master socket and nothing changes.

ADSL Link Downstream Upstream
Connection Speed 4872 Kbps 777 Kbps
Line Attenuation 35.7 dB 15.7 dB
Noise Margin 17.9 dB 15.9 dB

The figures are now worse, the speed stays a stable 4mbp/s but i was promised 8.9mbp/s by Talk Talk and used to get around 5.2mbp/s ( at best ) on the old BT Network under Zen Internet, i thought LLU would get me more downspeeds, i am getting higher upload speeds which is nice but clearly something is wrong.

I am currently using a Netgear N150 ( DGN 1000 ) router.

It looks like i might have to try the Talk Talk forums since i did not have a great experience with their phone contact number last year when having an issue with Zen internet and a 3 day loss of the net, of course Zen asked me to phone Talk Talk who in turn asked me to contact Zen, as it turns out the internet came back on and i believe it was linked to a BT outage in Edinburgh which also affected the Borders, funny how Zen couldn't tell me that but an internet search revealed it with relevent dates, anyways going off the point now.

Noise margin during the first ten days was much lower and i did not have disconnect issues so why it is higher now, well who knows.

If your site's host supports rsync, you could use that to do backups. Means that only the differences are transferred and not the entire site.

...might be worth the research

Your connection speed is alot lower than previous because the noise margin has shot up
And previous should of been higher anyway given the stats but you say you only got 5.2mbps on ADSLmax with what must of been a mid 30's at most line attenuation? I have 33db/34db line attenuation and can jsut make 8128kbps on ADSLmax in comparison....you must have some noise on the line or are they all overhead telephone lines?

Increase in noise margin = lower sync speed (usually)

TT run DLM and profiling dont they? If so I would suspect the DLM has shunted you onto a higher target noise margin because of noise and/or dropped syncs.

Havent fully read the thread but have you tried a different router just to make sure its not the router playing up and screwing the line up? And plugged into the test socekt on the BT master socket and making sure nothing is wired into the back of the master socket where the BT line comes in? (it shouldnt be AFAIK).

I'll look into Rsync, thanks for telling me about it as it sounds pretty good.

I don't think anyone is working over at the Talk Talk forums, no replies, i have had to reply to myself two times just to keep the post going, so far i'm a little disappointed in their forums as i had heard they were the greatest thing since sliced bread, i'm probably too impatient.

I asked them if i could be put on a 9db noise profile to see if i get a speed increase because i never had disconnections or issues when the noise margin was 10.1db and giving me around 2.5mbp/s more speed, therefore i feel it could be stable at 9db.

I have asked them if their dynamic line management system will see me disconnecting my router after i finish with my computer and mistake that switching off of the router as a disconnection and line issue and thus try and change things at their end, i used to have that issue with BT and Zen, i always switch the Netgear router off when not in use because it gets hot, very hot and i personally also feel its a waste of a small amount of energy so i switch it off when not in use.

The telephone lines are from masts and i have indeed tried a different router ( Xyzel ) and straight into the BT master socket.

I have tested packet loss and note at the recommended MTU setting of 1432 i get some packet loss, at 1400 i get no packet loss, not sure why that is but i told them on their forums.

:EDIT:

Just checked their forums again, my mistake, someone is clearly working there but just ignoring my posts, not even an hello, makes me feel so good about ditching Zen.
