Disconnects and subsequent increase in latency


[link to this post]
 
I've noticed 3 disconnects over the past 24hrs and each time, the latency has increased on my line as you can see here

Any ideas what has caused this?

Noise bursts for disconnects and may be interleaving changes or different gateway at Plusnet

Hmm what could be causing noise all of a sudden? Tried disconnecting earlier for 5 mins to try to connect to a different (lower latency) gateway and look what happened

Nasty how?

Shows a connection being used with 2 resyncs as a comparison.

The strange thing is that the connection wasn't being used at all. My PC was off and I have no wireless on my modem so am not sure why the graph looks like the connection was in use!

Edit: just checked thre link I gave above and it was the wrong one - it was for my parents which I was comparing mine too!!

Here's mine

Hence the 'nasty graph' comment smile

Is this ADSL or FTTC?

I had something similar to this when my boiler became a radio transmitter... my pings went through the roof and had frequent disconnections and slow speeds. I diagnosed that with an AM radio... or perhaps there's a fault on your line! I assume you've done the fault diagnosis stuff with Plusnet?

Plusnet unlimited FTTC

Have done this morning so just waiting for them to come back to me.

I going to plug it into master socket after work and see what happens. Very much doubt it's my wiring as that's what I do all day long in work!

Nothing new been added in my house but the modem is next to the wall of next door's lounge so am wondering if he has some next electrical equipment next door?

Edit: This is ADSL2+ by the way smile

Turn the ADSL modem off and go hunting with a battery AM radio for the noisy stuff

I think I'm gonna have to!!

Is it just a case of going around with no station tuned in (just the static noise) and waiting for the interruptions in the static?

Thanks

612Khz springs to mind on an AM/MW radio.

Good stuff - I'll give it a go later and report back my findings . . . . .

Well I searched for noise and no joy. Moved router about 50 across house to Master Socket and plugged in and still no improvement.

Has email on Friday from PlusNet saying that they had turned on Interleaving but this hasn't done anything. MY latest graph with disconnects etc:

here

Edit: Forgot to add that between 7pm and 11.30ish last night I was using Netflix - so that would describe some of the graph!

Umm nope not at all. I'm having all sorts of problems with high pings, page load timeouts etc.

http://www.speedtest.net/results.php?sh=5a6318872b0c... are my Sppedtest.net results for the past couple of years.

All of mine are the ones starting in 84. range. As you can see, up until last week, they were great. Then something happened at 4.45pm last Tues I believe and the pings/latency rose to about 40ms

I think I read somewhere that PN were adding / upgrading their Traffic management systems.. I cant remember if I read it in the PN Community forum or members portal ?

Maybe this maybe the cause of your problems if not REIN/Line fault..

I have noticed my ping times have gone higher over the past week 30ms +

My pings are largely unchanged (mid to high 20s, as usual). I noted they were increasing the 20CN and 21CN capacity recently. Maybe there's been a technical hitch for some users?

Hi guys - yeah I hope that's what it is but I have disconnected and left modem off for several minutes on a number of occasions over the past few days and all that happens is that the latency increases each time!!

My latest graph.

Latency seems to increase every 8-10hrs for some reason frown

That might be your problem. Not always wise to reboot too often. Is your sync changing too?

[re: camieabz] [link to this post]
 
The only reason that I've rebooted once a day is because the problem started in the beginning. I never reboot normally and until the day it started (last Monday) my modem had been sync'd for 43 days solid.

Sync always stays around the 16500ish mark.

It's really getting annoying now - good job I'm not a gamer ey?!?!?
