FTTC Intermittent Fault

Hi,

I have Plusnet fibre to cabinet speed problems that Plusnet aren't even trying to understand.
I tend to get about 40Mbps speeds downloads 10Mbps uploads. For several months during late evening /early hours of the morning my speeds fluctuate and average 5 or 6 Mbps download. During the week daytime my speed returns to normal. Sometimes but not always my telco line can be noisy too.

Can anyone suggest why the problems occur mostly through the night?

Thanks

Streetlights or your domestic lighting or that of your neighbours ...

Sometimes but not always my telco line can be noisy too.

So ring them and report it as such.

Are you saying the line is often noisy during the night ? Is the line fed overhead ? It might be moisture getting in to the dropwire, the current warm days then dry it out, and the problem disappears till the evening agin.

I wondered about that too, however the comment about several months made me think otherwise.

As the fault seems to happen in the small hours, there is nobody I can call at 3am.

The telephone line is only occasionally noisy, where as the internet speeds drop on a very regular basis. Underground connection.

The most recent test taken this evening at 19.25

Your test shows variable download speeds. Ok, I realise this is peak time for people online but not 2 or 3am.

My phone line and FTTC normally work fine, night and day, giving me about 36.5/8.1.

In the past week, I happened to go on at about 2 am, 23/9.3!

No noise etc.

Fewer than 96 lines on the PCP of about 300 lines, are upgraded to VDSL via the FTTC, so cause not immediately obvious.

Possibly something may show up when I get the SAMKNOWS Continuous Monitoring Results.

So it can happen.

You need to pursue that noisy line, using the Quiet Line Test to try to localise the source.
