For my line i get this

Our test also indicates that your line currently supports an estimated ADSL Max broadband line speed of 1.5Mbps; typically the line speed would range between 1Mbps and 2.5Mbps.

Our test also indicates that your line currently supports an estimated ADSL2+ broadband line speed of 2Mbps; typically the line speed would range between 1Mbps and 3.5Mbps.

and my stats
Down up
5851 888
Att
51.5 31.6
SNR
5.9 7.3

they never get it right

I got Be to change it to 9db SNR now I Get the following:

Downstream Upstream
Margin [dB] : 9.5 9.5
Attenuation [dB] : 57.0 30.5
OutputPower [dBm] : 18.0 12.0

Intrinsic/Actual Bandwidth %
Upstream : 99
Downstream : 83

Available Bandwidth Cells/s Kbit/s
Downstream : 7884 3343
Upstream : 2278 966

We'll see how many resets I'll get now!

I had an interesting chat with a tech guy at BT (after a high level complaint)
He suspects I have a line fault or a very poor line - Knowing my luck it will be the latter!

Anyone had any luck reporting a line fault and getting a lower attenuation (57db) on a 4km line?

You may be better with the BE box.

4km radius or you know for sure the line is 4km of phone cable?

3.5km of cable is around the 43dB mark, and 6km of cable is around the 60dB mark. So you aren't massively outside the ball park.

What is odd is that the current modem is saying it can go faster, but just appears to not want to. Another modem to verify, and switching between ADSL/ADSL2/ADSL2+ modes might be useful.

I have a new modem to try from BE so will try that once home

The BT guy said my line length 3.1-3.8 km

BE said I need to unplug my modem for them to do a line length test so will do so once at home to see what they say.

Historically I thought I had a 6km line so never thought much about my 57db attenuation
If its <4km though 57db seems on the high side...

Not unusual for BT people to tell you something, but miss out that they are telling you just the E or D side length, or even their records for the line are wrong.

Attenuation is the best indicator of line length and if voice is crystal clear and working, then its not likely you have unusually high attenuation due to a fault.

BTW Be will probably estimate line length by attenuation / 12 (or similar)

Where?

57 dB -> 4.1 km line length.

May have misread the line

If Be only estimate the length why is it necessary to unplug the kit to do the test?

So they don't measure the miles of your extension cables?
