A little explination.
Previously had excellent speeds both up and down 2Mbps/11Mbps
Then had really bad noisy line, which kept dropping out giving our alarm systems faults and also loosing broadband - this has been fixed now by BT changing the circuit (apparently) and the quiet line test is very quiet (!)
But now we have slightly lower download (10Mbps) but very poor (Compared to the original) of 0.3Mbps.
I'm using a Billion 7800N router (which was used previously) and this reports a SNR of between 6.0 and 6.8 - from what I can tell this is marginal.
I've tried my BT HomeHub and it drops out pretty much continuosly making it useless.
Here is the dump from my monitoring (after putting the billiion back on line) and leaving it for a little while;

I would assume that I should be able to get better upload speed (800k?) and perhaps even better download (13M?) but I'm quite happy with current speed its the upload which is the problem.
Mainly as I'm using a Vodafone SureSignal and the currently upload rate is marginal and give me bad call qaulity !
Any ideas - Can any of the clever Mods give me an explination or perhaps help ?
Welcome to this user forum.
The upstream connection speed should eventually improve, as the max rate is showing as 886 Kbps.
It can take a bit longer for DLM sort itself out, as the priority is normally to get the downstream rate back to normal.
Leave it alone for a couple of weeks, and if the upload does not improve, then a single restart or line disconnection should cause it to reconnect at a higher upload speed.
I get a similar issue on my line, where a burst of noise, or someone disturbing the line, causes errors on the upstream band, and it reconnects at a lower speed.
Because the line has a good connection history, a restart of the home hub fixes the problem.
There is some info about how things work on this thread.
Thanks you for the response, I will leave it and check back in 10 days and see how it goes.
Fingers crossed 🙂
