Re: SNR has suddenly increased and speed dropped

Post a selection of dusk/early evening and a late evening graphs anyway, as it will tell us a fair bit about your line. It might lead to some other check that could be done.

You don't need to resync the modem/router. If DLM decides it is going to lower the Target SNRM, it will all happen automatically. How long that may take depends, but if your line is stable (and clean enough) for a few more days, a manual reset could probably be requested.

Re: SNR has suddenly increased and speed dropped

It's been a week now with no disconnects. I have monitored the SNR 24hours a day and there has been no real incidents even at dusk and early evening. There has been 3 "blips" has shown on the attached graphs.

Are they significant?

My download speed is still only 75% of what it was before the problem started but is consistent.

 Would a SNR reset help get the speed back?

Re: SNR has suddenly increased and speed dropped

That looks pretty good actually. There appears to be virtually an insignificant change between daylight and night, and the blips are not significant - less than about +/- ½dB eitehr due to a bit of cross-talk or minor interference from some device being switch off/on.

I would think an SNR Reset would be a good idea. Perhaps @MatthewWheeler could oblige?

Re: SNR has suddenly increased and speed dropped

That's been requested and should hopefully go through in the next 15 minutes.

Re: SNR has suddenly increased and speed dropped

Fix

Thank you Mathew. The SNR is now at 6.2 and the BT profile has now increased as well.

Thank you again,

Rob.
