hi,
my speed has dropped considerably as you will see(attach).
Any ideas? Alan

Do a BT test, Alan, that will tell us more.
Hi Rik,
sadly it has been nigh on 18 months since I was able to get into BT for a test and I still can't,even with my new computer >:(
Alan
What are your router stats like, Alan?
I've had IDNet test your line, Alan. Your speed is right for your current profile, but not your current sync speed. That suggests that you've had one or more 'low sync' events which have pushed the profile down. In addition, your target noise margin has been increased to 12db, so BT's software is seeing significant instability on the line. Have we taken you through the ring wire removal route?
Hi Rik,
I have always had probs with random sync changes and variable noise margins,on the whole though the speed has stayed pretty constant,ok for my purposes anyway.
The connection properties are showing 3.9 mb.so where that test went wrong I do not know.
If it is truly at that speed,then I am happy ;)
Many thanks Rik Alan
Your sync speed is 3.9, Alan, but your profile is 250k, hence the very low throughput. Do you have an NTE5 master socket that you could connect to (or, more accurately, the test socket behind the faceplate?).
It sounds like there's been some nasty surges of noise. If you have a test socket, that would be handy...
Hi
yes we have been down this road a long time ago,I have always had heavy noise surges,sometimes to the extent of losing connection,but not for a good while now,unless of course it disconnects during the night,if that is the case I am not too worried about it ;)I don't have a test socket,so checking the line noise is difficult.I did however try to trace any random evening and night time household noises when I first had probs many moons ago,to no avail though..
Alan
Have you removed the rings wires, Alan (forgive me for not remembering)?
Hi Rik,
there were never any to remove Rik :)
Alan
It's probably going to be a difficult one to solve then, unless there is a line fault that shows up...
A long time ago,just after I joined Idnet I had this prob.I noticed then that things were pretty good during the daylight hours but gradually into the evening this got worse to the point of dropping connection at times.
Whether we have any am/rf noise in the area at night I don't know,as you say,it would prove difficult to find,and at 72 I don't relish the thought of mooching around the neigbourhood at all times of night running the risk of arrest LOL.As long as I can do my flight simming without disconnects,I'm reasonably happy.
Alan
Street lights, maybe? Or perhaps, the old BT congestion problem? :dunno:
Over the last week i've had this problem too to the point where Youtube videos take an unbaringly long time to buffer.
Even websites timeout because they take so long to load!
I had also taken out the ring wires and do not have a master socket. I hope it goes away, Internet is literally unusable at the moment
What are your downstream stats, sync speed, noise margin and attenuation? What result do you get from a BT test.

It can't be, Simon, as there's been a profile drop, therefore a 'low sync' event.
I'll get my coat... :out:

QuoteTest1 comprises of Best Effort Test: -provides background information.
Your DSL connection rate: 5056 kbps(DOWN-STREAM), 448 kbps(UP-STREAM)
IP profile for your line is - 4000 kbps
Actual IP throughput achieved during the test was - 3801 kbps
That looks spot on, which suggests exchange congestion. If the problem continues, try to get a BT test done at the time, and let support have the results so they can take a look.
I'll give them a call right now, it's gotten sooooo bad Rik =/
But wouldn't you say the amount of errors is too much?
I don't know, Em, how long had the router been up?
Well, not long as it sometimes kills the connection so i'm forced to restart it.
Here's the latest inc. uptime:

The sync is a bit low for that attenuation, but not bad.
From the stats, does it show that I have a bad line in anyway?
Maybe a new Router might help?
I'm using a Speedtouch 585 v6. Any suggestions?
Well I just done a hardware reset to see if it helps and so far I am a very happy man! :thumb:
Not sure what it was, maybe the Router was clogged up but so far it's going very well.
Many thanks for everyones help and sorry for hi-jacking the thread :red:
Oh and here's the line stats so far:

I'd suggest you contact support, Em, and ask them to test the line.
As in BT?
As in IDNet, BT won't talk to you, you're not a customer.
You have to go through your ISP, even if it's a line issue. Silly, but true. :)
