Router or line problems

[Glenn]

Just checked the heating comes on a 5.30, but the resync was at 4.31, I just added an hour for BST but it was already set at BST

Damn, there goes another theory! It is, though, within the window for BT's work this week.

[Glenn]

Is there a list available of what exchanges were worked on and when?

[Rik]

Not that I've seen, unfortunately. I think much of the work is on backhaul and fibre, reading between the lines.

[Glenn]

Just done a speed test, the line has been up for the past 2 days without a resync

Test1 comprises of Best Effort Test:  -provides background information.
    IP profile for your line is - 1500 kbps
    DSL connection rate: 448 kbps(UP-STREAM)  2752 kbps(DOWN-STREAM)
    Actual IP throughput achieved during the test was - 1382 kbps

Hopefully if the line can hold it's sync the speed will improve, but the router is now reporting "Suspicious - impulse noise detected" which I have never noticed before.

I've seen a couple of people mention that, Glenn. Apparently it means exactly what it says, though I still don't really know how to interpret that. Let's hope your sync holds and your profile should adjust in the next few days.

[Glenn]

Hmmm... something is going on, after 5 days of no re-sync, the line dropped and the router rebooted at 05.30 again this morning. I was up this time today and the heating came on at 05.41, so its not that, the street lights were already out too

[Rik]

The only thing we can say with certainty is that if it's happening at the same time each day, it's got to be electrical noise. I don't recognise this 5:30 of which you speak, Glenn , but if you're up that early again, could you try having a detuned MW radio near the router and listen for a noise burst?

[Glenn]

Rik, the strange thing is that it happened on Monday, it has been fine for the rest of the week, then happened again today so it's not everyday.

[Rik]

The plot thickens. How long has this been happening?

[Glenn]

Just this week, so that makes it even stranger, I wonder if BT did some work Monday morning and today?

[Rik]

It's in the right time slot for their scheduled work.

[Glenn]

I think another call to support maybe in order. After 4 days without a loss of sync today it has resync'd 6 times with approximately 45,000 CRC errors since 12.18 this morning!

[Sebby]

That would suggest a lot of noise on the line, but that doesn't necessarily indicate a fault; unfortunately, the noise source may well be local.

[Rik]

I had something similar at the beginning of the week, Glenn, and found that BT were working on the cables just up the road.

[Glenn]

I got home today to find that the router has re-sync'd 11 time since 2pm today, strangely it reconnected a 6 times at 0kbs  The attenuation has risen again to 60.4 from 59.7 5 weeks ago

I have emailed support to get BT to take another look at the line, if they can't find a problem remotely then to get an engineer to investigate.

[Rik]

It's got to be a line fault or something chucking out some really serious noise near the line, Glenn. I hope BT track it down for you.

[Glenn]

I do hope so

[Sebby]

Hope you get it sorted.

[Glenn]

BT engineer is due to take a look tomorrow hopefully he will find something

[Rik]

We'll be bating our breath till we hear, Glenn.

[Sebby]

Fingers crossed!

[Glenn]

Well it's 11.45, still no sign of the BT eng

[Rik]

Get the bacon butties going Glenn, they can smell them for miles.
