Fttc dropping out


[link to this post]
 
Hi all,

Over the last month I have been having issues with BT Infinity dropping out once every few nights around the 8-8.45pm mark, I have read this could be some sort of noise coming from something automatic like street lights etc but if this was the case would it not be the exact same and everynight?.

I did call BT about this and after a few calls they said they would change my line profile and I lost about 15meg but it was stable then the speeds increased and the issue returned. But I have had those speeds since day 1 in september of last year and nothing has happened until a month ago

I am using the HH5

5. VDSL uptime: 0 days, 00:00:34
6. Data Rate: 15972 / 67801
7. Maximum Data Rate: 15972 / 68782
8. Noise Margin: 6.0 / 6.3
9. Line Attenuation: 0.0 / 20.2
10. Signal Attenuation: 0.0 / 0.0

The line is currently in the test socket with a filter rather than the openreach supplied faceplate

Could anyone give some advice?

If you think it is regular - at around the same time, then get a copy of DSLStats and leave it running, monitoring SNR at intervals of a few seconds. If you can start it at say 19:30 and leave it running it would be ideal. After a few nights, have a look to see if there is something occurring.

Street lights do not turn on at the same time - they tend to use Lux sensors to determine if it is dark enough to turn meaning that it could vary considerably day to day.

Your speeds look reasonable for the attenuation - at a guess you are 600 to 800 metres from your cabinet.

Could try this. I find it good at tracking problems. https://www.glasswire.com/

Also gets decent reviews. http://www.pcworld.com/article/2686040/glasswire-rev...

more like 400-500m

I'm 65000/19999 at 450m

Also not sure how Glasswire is supposed to help troubleshoot DSL disconnection issues!

For a comparison, I'm 850m away from the cabinet and my attenuation is 21.5.

Oh yeah, I missed that bit... my attenuation is 16db...

So he is getting a very good sync then for his line.

I'm having a similar problem on my line and it's not an SNRM problem (SNRM is fairly consistent).

I think the first port of call would be the test socket.

I have heard of the BT Home Hubs not having the best VDSL modems so that might he contributing too?

Thanks I will try that... Yea about 600m away unless it's taking a path I highly doubt

Possibly but if that was/is the case wouldn't it be all different times rather than the time frame I stated?

Based on attenuation figures not sync.

And your sync is low for 450m - mine is up at 77360/19999 on a line of around 420m.
