Wierdness again


[link to this post]
 
Hi All,

Need a bit of help/guidance again please smile

Sunday morning my normally solid 80/20 decided to have a fit again and has retrained at 58/7.

The only obvious difference I can see is that Interleave depth has changed from 16 to 8 and INP from 48 to 49 and my max attainable is now lower than my connection speed.

What was also a healthy noise margin of 7 down and 14 up has now changed to 6/6.

Stats etc. are available on mydslwebstats as NGDragon if anyone has a clue what they mean smile

Any help greatly received...

[re: NGDragon] [link to this post]
 
There's no reason obvious on MDWS, but I'm so late to looking that some of the useful comparison graphs (from "before") are no longer visible - Hlog, QLN, SNR/tone and bits/tone are all only available from 00:00 on the 24th.

The current Hlog graph doesn't look particularly good in the lower tones, so there might be a fault on the line. But there is nothing with obvious evidence.

Might be best to report it as a sudden drop in speed, and see if the ISP will book an engineer to take a look.
