adslmax what do you use your connection for?

Some streaming? General web browsing?

Any real impact from the change in speed to what you do with it?

I have a 25/1 connection and its enough for 2 people to stream, game, do what they like. Do I want a faster connection? Yes. But would it really make any difference to day to day life? Nope.

Enjoy your 60-80 down and 20 up! Go watch some TV or play some games!  ;D

If you currently don't need to use your connection to the Internet, then power down the modem whilst the repair work is ongoing. That way the DLM process will not take any action on your circuit.

The line went back to 80/20 shortly after 6pm so must be the work by openreach today.

dont thin its crosstalk, looks like interference and probably caused by the ongoing work.

Everything went back to normal now.

SNR steady solid at 6.9dB for 15 hours now. But why is line attenuation increase to 12.7? Before used to be 11.5?

Attenuation reported by modems is not the same attenuation as your physical line that BT might use to judge distance or speeds your line might get, with the modems attenuation more an average based on all frequencies received which varies meaning this attenuation figure can vary also.  Your true physical line attenuation which is measured at a fixed frequency of 300KHz is very likely completely unchanged.

The trouble is with modem stats is you can't really take any single figure and draw any conclusion from it changing, as its a balancing act you need to consider other values alongside it. 

I suspect your modem is receiving higher frequencies than it did before so your average attenuation has gone up, because these higher frequencies have a higher attenuation.  This actually shows an improvement in your line, the opposite of what we might expect seeing that attenuation figure go upwards.

Regards

Phil
