A switched on customer service agent or a forum moderator can change the line speed (if you e-mail them then you will get a response in about 3 days).
It will of course deteriorate if you are having disconnections and slow sync speeds.
Can you access the Event Log on your Hub? - Under "Troubleshooting" on the right side. You will find a bunch of lines about DSL down after x minutes up time, and show you the sync speed when it reconnected (often lowest in the middle of the night). Lots of these might indicate a noise problem. The slowest sync speed is what sets the IP profile (that's only, if you are on the old system, the new system resets to 88.2% of your current sync speed each time you reconnect). I found a workaround was to turn the hub off in the night when most of these occurred to keep my IP profile up. But then occasionally got duff sync speeds during the day anyway so it didn't work particularly well.
It seems that I really need to erradicate any problems my extension lead may be causing.
So it's up to me now to decide how best I could do that.
Apart from advise on who I need to contact (and how to contact them) so that my Noise band & IP Profile can be changed, am I right in thinking that I really should get rid of the extension lead before I connect up the replacement hub.
That is will the replacement hub come with Noise band set at 3-6db and IP Profile at 2.5Mbps only to possibly go the way of my current Hub.
A new router may be better able to hold onto your line. If you disconnect less, your noise margin should automatically fall (although it does get stuck sometimes and needs manual intervention) The lower your noise margin setting the faster the exchange and router will be able to synchronise and then the IP profile should rise to follow. Remembering your IP orifile will never match your sync speed as there is a significant amount of traffic overhead (+ other technical reasons).
If the noise margin and IP Profile is a line management thing then the new hub will just carry on with the same noise margin, IP Profile and speeds that my current Hub does.
I now understand that line management is automatic, but how do I get manual intervention with the noise margin so that the IP Profile & speed increase.
Does leaving the hub connected mean leaving the power on the hub with internet explorer open all the time, or just leaving the power on with the computer shut down ?
If a flat extension line is defined as a line that is physically flat then I have a flat extension line.
Sorry just realised that Gouledw has already told me how to contant the mod and request an SNR reset
Then yes thats the most likely cause of your broadband fault, the flat extension lead. They absolutely have horrible affects on broadband!
And with the manual intervention from the mods, please be aware your line may become even more unstable. Here's the link http://bt.custhelp.com/app/contact_email/c/4951 they take around 3 days to contact you. 🙂
