speed lowest ever

alcav · Mar 30, 2009, 16:31:13

hi,

my speed has dropped considerably as you will see(attach).

Any ideas? Alan

Do a BT test, Alan, that will tell us more.

alcav · Mar 30, 2009, 17:12:19

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

What are your router stats like, Alan?

Rik · Mar 30, 2009, 17:36:39

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?).

Sebby · Mar 30, 2009, 18:33:29

It sounds like there's been some nasty surges of noise. If you have a test socket, that would be handy...

alcav · Mar 30, 2009, 19:11:58

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..

Rik · Mar 30, 2009, 19:14:40

Have you removed the rings wires, Alan (forgive me for not remembering)?

alcav · Mar 30, 2009, 19:50:23

Hi Rik,

there were never any to remove Rik

Sebby · Mar 30, 2009, 21:02:20

It's probably going to be a difficult one to solve then, unless there is a line fault that shows up...

alcav · Mar 30, 2009, 22:23:37

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.

Street lights, maybe? Or perhaps, the old BT congestion problem?

emzino · Mar 31, 2009, 01:02:28

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

Rik · Mar 31, 2009, 08:18:33

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.

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.

emzino · Mar 31, 2009, 16:03:26

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?

Rik · Mar 31, 2009, 18:47:26

I don't know, Em, how long had the router been up?

emzino · Apr 01, 2009, 21:42:21

Well, not long as it sometimes kills the connection so i'm forced to restart it.

The sync is a bit low for that attenuation, but not bad.
