Fibre Performance

The dsl checker at https://www.dslchecker.bt.com is showing the following speeds for my line:

FTTC Range A (Clean) 48.7 33.8
FTTC Range B (Impacted) 40.3 24.1

What I'm actually getting is between 17 and 19.

Is this likely to be my line at fault? Is it worth me getting anyone to fix it or am I going down the rabbit hole - the speed is quick enough for what we need.

The stats from the router are ( Upstream/Downstream)

Current Rate (Kbps) 4246 15098
Max Rate (Kbps) 4097 17848
SNR Margin (dB) 5.5 5.9
Line Attenuation (dB) 27.8 24.9
Errors (Pkts) 0 0

Cheers,

Tim.

Are there speeds when connected to an extension socket or at the test socket on the master socket

e.g. http://www.coolwebhome.co.uk/faceplate/

How is a fibre customer supposed to plug an OR provided RJ11 in to the NTE5 test socket...

The user should have the modem plugged into the Interstitial Plate installed by Openreach... unless the customer is a self install and has a dangly filter hanging out front of socket!

More importantly, how is a fibre customer supposed to access their line stats as a BT supplied modem doesn't allow it!

I don't follow what you are saying.

Look at http://www.coolwebhome.co.uk/faceplate/ the removal of the interstitial plate is part of the diagnostics should do even if they have one. Faceplates can break/fail so testing at the test socket is worthwhile and some engineer installs are less than perfect too.

It's connected to the master socket. It's a self install, so there's a microfilter hanging out of a normal telephone socket. I've tried different microfilters.

Try the test socket and see if it improves things. If not I would report it to Zen as a fault.

As a self install with external micro filter using the test socket is fine... but for someone like myself with an engineer install and having a faceplate filter, how am I supposed to plug an RJ11 or RJ45 as mine is into the BT Jack socket?

With a suitable cable or a microfilter

Feel free to not bother if its too much bother of course

OK and how many people have got a selection of cables available to do such a thing?
