On start of DSLStats this morning DS SNRM had risen to 9dB.

[roseway]

It appears that DLM has got you.

[renluop]

A FWIW update.

Was out most of day, in which time DSLStats had stopped working. Restored all was much as in the morning.
For a few minutes either side of 17:36 DS SNRm to 0, or may be less. Around 18:10 Sync dropped from
 5000 to 3100 kbps and tones in use maxed at # 125. QLN is once more not as it should be (b'cats comment).*

I wonder if Kitz got anything from the SNRm graph she requested.

S..'s Law; all this is going on, when after nearly a month of hoop jumping, I've just got a loan satellite box for one that has a fault less than 6 months from new.
* All back to where it was in~ 40 mins.

I hope it isn't too forbidden!
Possibly a waste of time, I am running the rival (Routerstats Lite) along with DSLStats in case it shows anything up at failures and beyond. If wanted, I'll paste an abridged log.

I am now getting "unable to read data from file special routers.dat" and "unable to read data from file routers.dat" on starting the program. The program runs once the warnings have been cancelled. Are the warnings particularly significant?

Where is DSLstats installed? Those messages occur if DSLstats is installed in an unsuitable directory so it has difficulty reading the files in question.

I doubt it is at all relevant, but I have a MasterPlug tower. It has an input from the phone socket, and output to the router, so I ask if there is a downside to that configuration, that could be in part a culprit.

Wouldn't the obvious thing to do be take that MasterPlug thing out of the phone wiring entirely? I assume the MasterPlug thing is supposed to be providing surge protection for the phone line.

I have done the obvious, and it doesn't seem to have had any obvious effect on the problem. As the router's line is the extension (hard wired), I'm not sure of the protection any way.

C\ProgramFiles (x86).

[roseway]

As I recently discovered in a different thread, Program Files and Program Files(x86) are not suitable locations for DSLstats. The reason is that these folders are not fully accessible to ordinary users. Install DSLstats under C:\Users\<Your name>.

[renluop]

And clearly not useless users like me! Thanks, Eric!

[roseway]

It wouldn't be fair for me to agree with you

That abridged log is attached just in case it may show something. One small thing is how attenuation can vary by ~3dB within minutes. That variation i worked as, say, 200 yards.

[ejs]

Could it be varying between ADSL1/2 and ADSL2+?

[renluop]

Telnet reports adsl 2+ and that's what router is set up for. How could a connection fluctuate between modes?

[ejs]

Does it report ADSL2+ when it shows an attenuation of 43.5dB?

In general the mode would be negotiated at the time the connection is established, and some exchange equipment will switch the mode automatically based on the usability of the extended ADSL2+ downstream tones. And 3dB is approximately the expected increase in reported attenuation from ADSL1/2 to ADSL2+. Of course, if the modem is set for ADSL2+ exclusively, and/or it always reports it's using ADSL2+, then it's not that.
