Re: stability

Fast service is got by calling.
You may or may not get a response here, and if you do, it may be soon or in a few days.

If you want help from PN staff, then they'll probably be back on here on Monday morning... and they're the only ones who can "look at it" with no more info in the post.
I suspect that when they get here, they'll point at the same initial troubleshooting procedures, and a fault being raised.
As 44D says, the fastest response will probably be by calling.
If you want help from any of the other users infesting the forums, then post some more information about the problem. The line statistics from the router would be a good start...

Re: stability

HI monkey001,
I've noticed you have not called us or raised a ticket. Are you still having problems?

DownStream Connection Speed 2688 kbps
UpStream Connection Speed 352 kbps
problem is with upstream anything to do with the upgraded upload that is on the line and it is normally around 750kb ?Huh
Ping has been all over the shop aswell.
attached router stats.

Re: stability

Does Routerstats show the noise margin per tone with that router.
If so can you post the Bits and SNR per Tone Graph

Re: stability

Thought so - you almost certainly have a cross talk problem probably at the exchange and it will be an absolute pig to get it sorted.
I fought that one for over a year and eventually gave up.
Then I was moved over to 21CN which was a different board in the exchange and this was the change.
These pictures are from DMT but you can see the shape.
Also the second picture is from Routerstats to show what it should look like

Re: stability

HI monkey001,
I think the first thing you should do is raise a fault so we can start investigating this thoroughly for you.

Thank you i knew i always had a problem just no one believed me.
Now what the hell is cross talk lol?
And there will be no way of me switching to 21cn date isn't even there at the exchange Sad


Will do Jojo

Which aspect of the graphs is most indicative of crosstalk?
My guess would be the gradual increase in #bits in the downstream tones (in the before graph), while it immediately starts high (at the lowest downstream tone) in the after-graph.

In voice days, it would be when you could hear your neighbours talking on the phone line. In DSL days, it is the interference of your DSL signal by other DSL customers. After all - every single customer is trying to use the same frequencies, on copper lines that are carried in bundles. As the bundles gradually get more DSL customers ("cable fill"), so each individual line sees more interference from other DSL lines.

Re: stability

So my chances of getting this fixed are slim then?
btw raised a ticket to which the answer was
We have asked our wholesale broadband suppliers to turn interleaving on on your phone line to try and fix your current broadband problem.
Interleaving is a form of error correction that helps to improve the stability of high-speed broadband. One drawback of interleaving is that it can increase ping times, which may cause problems for online gamers.
We think that turning on interleaving may help with your connection problems. Interleaving usually takes 24 hours to turn on, but can take up to 5 days to take effect.
If interleaving solves your problem, please close this Question. If you are still seeing problems with interleaving switched on, please return this Question to us with as much detail about your problem as possible. Thank you for your time and patience.
Kind regards
Plusnet Customer Support

Interleaving is already on :/

Re: stability

Basically something is mucking up the upper end of the upstream frequencies and the lower end of the downstream frequencies.
So something is putting out interference in those frequency bands.
As mine was fixed by moving to a different board in the exchange and before that the problem was very intermittent I assumed that something on the original board was creating interference and that this was cross talk from some other line or lines on the board.
It should have been fixable by a lift and shift but Plusnet could never persuade BT Openreach to do it.
At that time neither I nor Plusnet was aware of the significance of the bits per tone graph

Its probably back to first steps here, just to be sure... We need to rule out that the interference is coming from your internal wiring, or any phone you have connected.
Where is your router plugged in to the phone line? What extension lines do you have, and what other devices are plugged in to the phone line?
Can you give us a set of router statistics that come from the existing location; then plug the router into the test socket (at the back of the master socket) alone (ie nothing else plugged into the line) and do another set.
