Speed permanently lowered

[#1 · Accepted solution]

Good news!

And to confirm the profile speed our side is set to:

Calculated downstream data rate: 79671 kbps

Yes I wondered why services kept setting my location to Sheffield no matter how many times I made it clear to all  my devices I am in West London.

The speed profile is configured based on the speed of the line using TR-101 where BTW (for ADSL) or Openreach (for FTTC/SOGEA/FTTP) send the speed of the line as part of the PPP at the point of connection and we reflect that back onto the network so they should always match.

That is how it works on 'high touch' connections.

Is there ANY sort of limiter on 'low touch' connections ? - and if not how is it that there isn't packet loss at the network's slowest point (i.e. the bRAS limiter between the 'exchange' and the customer's modem) ?

The location is associated with the assigned IP address which is very likely to be the Sheffield data centre.

QoS was raised early on as a potential issue.  Difficult to understand why one would tinker with that.  In domestic settings it tends to cause more problems than solutions.

Why do we play with QoS?  We have a realtime-sensitive server at home - Jamulus actually - and it takes absolute priority for throughput.   My partner is in charge of that and I leave him to set up the QoS as needed.  He checked the settings he made, at the time we first noticed the problem.  The setting that was affecting our speed was one that had got altered accidentally by some random slip of the finger apparently, so he didn't check that section.
