Hi

Connected and running all okay so far.  What is the trick to get Telnet so I can see the line stats?

Regards

Phil

These are useless by Netgear! Very poor old dated web UI design on the new D7000. Netgear never care to get a full stats on VDSL. This is the reason I won't buy Netgear anymore!

All stats are accessible via telnet unlike some routers.

Well something has happened this morning to my line and something I've never experienced from any device.
Netgear engineering asked me to check if my SNR recovers from a reboot. It did. But having a look at the stats, my inp level has also reduced now and my interleaving depth is at 8!!! It has always been 16 or above. I've never seen this before.
Ardsar, can you do the same please and reboot when you get a chance to see if you get a recovery of SNR.

reboot is bad way for FTTC as it will cause DLM to trigger if you do reboot it. But, I think doing it one off will be ok but don't reboot it too many times.

I never heard of this reboot to recover SNR. That's got nothing to do with it. It's up to DLM to decided not the router reboot.

Im sure a reboot will recover the S/N as this will recover the bins that have been marked as bad, but the S/N will only drop again in the evening as the bins are again marked as bad. Looking at my bin/tone loading it is very clear that areas where the s/n drops at night result in those bins being disabled. On other routers, the bins come back into play when the S/N recovers. You can see this on MYDSLwebstats> prior to using the Netgear on Friday evening, you can see my S/N drops in the evening and recovers during the early hours - by around 1 - 1.5 dB. However with the Netgear, the S/N dropped as usual but did not recover in the early hours resulting in a fairly flat line since Saturday.

I may power off for 30 mins and then power back on when i get home......

Netgear need to be advised to look at Bin loading and bit swapping algorithms.

My SNR returned to normal after a reboot. Well off for 30 mins and back on.

I've also swapped to the hg612 as they wanted stats and info from that to compare alongside the stats of the D6400.

What I think has happened with my line in particular is that due to the lowering of the interleaving it has estimated my Max attainable as a bit lower resulting in the SNR to drop to maintain my existing sync speed. After my reboot im syncing slightly less but have a better SNR.

As my line is on g.inp that is known to mess about with attainable rates so I'm wondering if this has contributed to the issue now that is has lowered slightly also.

Why don't you just leave thing alone. I wouldn't mess around with it. Not worth it. As for SNR it pretty normal to go and down in this weather plus day & evening are always change in SNR. My router stay online sync for 25 days since Openreach change in G.INP interleaved from 16:8 to 16:1

Yesterday (last night):
Code: [Select]
SNR Margin (dB) 8.5 14.8
Attenuation (dB) 11.7 0.0
Output Power (dBm) 12.4 0.0
Attainable Rate (Kbps) 90117 30859
Rate (Kbps) 79999 19999

Today (now):
Code: [Select]
SNR Margin (dB) 9.3 15.3
Attenuation (dB) 11.7 0.0
Output Power (dBm) 12.4 0.0
Attainable Rate (Kbps) 94926 31187
Rate (Kbps) 79999 19999

Think the point is there appears to be an issue with the device which we are trying to get resolved. Agreed it is usual for s/n to fluctuate as my line always has however with the netgear fluctuation is only one way -ie down which is different to any other device I have used

Because I'm trying to assist Netgear and Ardsar to get to the bottom of what they are seeing. I don't care if DLM kicks in, It will always recover when it sees that the line is stable. It doesn't bother me one bit.

I am aware SNR will fluctuate with seasons and weather but why are they not recovering when they normally do? This is why I am trying to provide Netgear with as much info as possible. If no one does then how do they know there may be an issue?

I think Netgear wouldn't care less as they are best known as poor customer support and their forum help is useless too. I just glad to see the last in Netgear! Never go back to Netgear ever again.

NETGEAR are pretty poor to be fair.

They released a broken DGND3700 and then fixed it by releasing a DGND3700 v2 the next year: the DGND3700 was never fixed.

Also the fact that their software always has bugs, the WiFi performance on most of their routers is average at best and their support is dire, I would say it is fair to dislike them strongly as a brand.

Been using the D7000 for around 15 hours now - it was switched on around 5pm on Friday. The changes can be observed on MyDSLWebstats - profile ardsar.

Initial observations -

1) S/N for downstream was approx. 1 db lower than what the Billion 8800NXL reported
2) Interleave was reduced from 801 to 531 (it has been stuck at 801 since around Christmas)
3) Performance seems good.

What I have noticed however is that the S/N usually drops by approx. 1dB at night and then recovers. On the D7000, the S/N has not been recovered. If I look at the S/N per tone graph, the areas that dip at night have recovered, however the bit loading graph seems to suggest that these areas are still poor (around tones 1700). Would this be why the S/N has not recovered this morning?

As can be seen from the attached more bins are now not being used - hence the reduced S/N. THe net result however is that the S/N graph has flattened out, rather than oscillating by 1dB per day.

Ardsar, Check your PM's. One of the D7000 engineers wants to have a chat with you to get to the bottom of the issue you are seeing. He has been most helpful with me so assume he will do what he can for you.
