New service slower than hoped for, and confusing router stats

I was originally given a download speed estimate of 20-27. I am using the Hub One modem/router connected directly to the BT test socket and am getting the following stats:
6. Data rate: | 3192 / 17453 |
7. Maximum data rate: | 3287 / 17852 |
8. Noise margin: | 6.4 / 6.4 |
9. Line attenuation: | 46.8 / 27.8 |
10. Signal attenuation: |
35.0 / 21.4 |
Can anyone please explain the difference between line attenuation and signal attenuation? It seems that my sync speed is related to the 'line' attenuation (based on the DSL calculator on speedguide.net that I tried). I am wondering why there is a big difference between the two numbers. I have seen other people quote their stats as above, and both line and signal attenuation are very similar. If mine were both 21.4 I might be able to get around 21.5Mb - I am wondering if this is possible?
The BT figures for my cabinet give a clean range of 20-28.6 and an impacted range of 9-22.3. So I appear to be in the impacted range from the outset.
My line is stable, I've been connected for over four days and I just tried rebooting a little earlier, to see if I might attain a better speed but there was no change.
If this is the best speed I can get then I will accept it, but I am wondering if I could be doing quite a bit better here.
Further info, my cabinet is ECI and so is the Hub One (based off BT Home Hub 5A) so that should be optimal.

Do you have one of the latest filtered master sockets, and are you plugged into it? It could be you internal wiring that is holding your speeds back if not.
Have a look at the troubleshooting guides in the help section.

I had very slow speeds when my Fibre Broadband was installed which were no better than my previous broadband. After chatting to support they noticed that something hadn't been switched over at their end and I was still effectively receiving the same speeds as before. They changed it there and then and now I'm getting close to 40 Mbps Down and almost 2.00 Mbps Up.

I am connected directly to the test socket, so I am bypassing the internal wiring and eliminating it as an issue.
This is the sort of socket I have.

Perhaps I should have added that this is a new service at a new property (not a new build, I mean I've recently moved here).
The speed I am getting is very much in the ballpark of what would be expected given the long distance from the nearest cabinet etc. so it could well be that this is as good as I will get.
I am curious about the line / signal attenuation stats as I mentioned in the OP though, so if anyone knows specifically about that, I would be very interested to hear about it.

Ok, then I suggest you give them a call, or get on chat and see what the problem is.

I did phone them on the first day of the service, when I found it was well below the 20 minimum I had hoped for. He did a test on my line and found no faults. He said it may go up over time.
The BT wholesale speed test passes without faults and says my acceptable range is 12-17. So the speed I am getting will not be deemed a 'fault' (and I know it's better than many people can get - but where I moved from, I used to get 80/20 full speed so I would rather get 1/4 of that in my new home if possible, rather than 1/5! :))

Ah ok, I thought you said you were expecting 20 and above. So if dsl checker says you are within the expected range, then not so much you can do.
Alas I can't help much with the other figures, however there some very knowledgeable people on here who may be able to help.

dslchecker.bt.com for my address says the clean range is 20 - 28.6 and the impacted range is 9 - 22.3.
What I don't know is if being within the impacted range would be deemed any kind of fault.

Thank you @Anoush, I have just done as you suggested.

Thanks for that. I've reported the fault through to BT and updated your ticket. If you let me know on here once you've replied I can progress this for you.

So it looks as if I will be declining the engineer visit offer, as I could be charged if 'no fault' is found. Which to me seems the most likely outcome, as I am getting a speed close to what would be expected, and well above what BT deem a minimum acceptable speed. And no disconnections etc., the line is stable. I can't risk paying £65 which to me is a lot of money.
If a Plusnet support rep could kindly explain the relevance of line and signal attenuation in the router stats, it might well help to better inform my decision and identify if there is anything of significance there.

I've been discussing this with one of my colleagues. From looking at your line length of almost 1 mile, it's very likely that this is the best speed your line can achieve so I agree it's probably best not to go for the engineer.
I apologise if I caused you any disappointment by asking you to raise the fault.
I'm not entirely sure of the difference between line & signal attenuation. For fibre circuits we don't really see this though for ADSL it provides an indication of how long your line is.
Here's my test results for your reference:
Test Outcome | Pass |
Test Outcome Code | GTC_FTTC_SERVICE_0001 |
Description | GEA service test completed and no fault found but unable to check for customer equipment connected to modem. |
Main Fault Location | OK |
Sync Status | In Sync |
Downstream Speed | 17.5 Mbps |
Upstream Speed | 3.2 Mbps |
Appointment Required | N |
Fault Report Advised | N |
NTE Power Status | PowerOn |
Voice Line Test Result | Pass |
Bridge Tap | Not Detected |
Radio Frequency Ingress | Not Detected |
Repetitive Electrical Impulse Noise | Not Detected |
Cross Talk | Not Detected |
Estimated Line Length In Metres | 1313.3 |
Upstream Rate Assessment | Good |
Downstream Rate Assessment | Reasonable |
Interference Pattern | Not Detected |
Service Impact | No Impact Observed |
Home Wiring Problem | Not Detected |
Downstream Policing Discard Rate | 0.0 |
Customer Traffic Level | Upstream and Downstream Traffic Detected |
Technology | VDSL |
Profile Name | 0.128M-80M Downstream, Error Protection Off - 0.128M-20M Upstream, Error Protection Off |
