These are not wildly different from those of about 4 weeks ago, apart from the data rate down, which was sitting at about 4400-4900, and the attenuation which is greater
Were the results obtained 4 weeks ago from the same router i.e. the ASUS?
The downstream SNR margin value is higher than the BT target setting of 6dB so is causing a reduction in sync speed when the router resynced, something (noise) has caused the DLM in the exchange to increase that figure from 6dB to 12.5dB in order to stabilise the connection and stop more resyncs to the exchange.
If there are no more problems with the line then the router should be able to sync with the exchange at around 4890Kbps when the DLM drops SNR margin value back to 6dB.
With the throughput speed of 2.85Mbps this would indicate your connection has an IP profile of 3000Kbps/3.0Mbps which ties up with your current sync rate of 3904Kbps.
It could be worth connecting the router to the TEST socket within the master socket if you have that type > TEST socket
and getting a new set of line stats to check if there are any wiring problems your side of the master socket, it might be better to do that in the morning/daylight as you ccould end up with a lower sync rate by reconnecting in the late evening.
It can take a long time 10 to 14 days for the DLM to reduce the noise margin back to 6dB as long as there are no more router resyncs due to line noise/issues.
You can get the margin reset to BT's default of 6dB by getting in touch with the ISP/madasafish/Plusnet customer services but they will only sanction it if your connection is stable when looking at the stats and other data from their end.
Edit > forgot to ask are the line filters in use OK.
