ADSL24/Murphx speeds

Has anyone else had a problem with the down load speed of ADSL24 Murphx dropping to unacceptable levels during the peak periods?

Long story short, (I have a thread in the ADSL Technical Forum with more info), my speeds drop consistently from around 4.50Mb/s during the day to around 0.50Mb/s after around 16:00 and most of the weekends. This has only happened for the last couple of weeks.

ADSL24 Tech help have been very good in running test etc but have found no problem with their end, (and Murphxs' I hope), and have thrown it back to me and BT to sort out.

Am I alone here?

Check your exchange here for possible VP congestion.

Yes, thanks.
Already did that and the VP shows green and has been for quite some time.

I think it must be specific to your line / geography, as I have had no such issues.

I suspect you are right and I hope it returns to normal soon.
I am in mid Norfolk.
I don't want to leave because I like the company but if it is the local ADSL24/Murphx pipe and it doesn't recover then I might have to.
There is not much you can do on the modern internet with sub 1Mb/s speed other than Usenet or non-graphic intensive WEB sites.

When you have the problem, I assume you have tried to ping each hop in a traced path to look for latency / packet loss? It isn't that likely to show much, as most of network is included in the first hop, but you might uncover soemthing.

I've been having the same problems recently. Last night somthing strange was going on. Usually my ping to bbc.co.uk is around 20. Last night it was 300-800ms! I also pinged each hop and it seems the problem is with the first murphx hop.

I'm only new to ADSL24 so have not yet got a feel on what to expect as normal speed - so I cannot comment on that.

I do seem to have packet loss during the day (as reported by the TBB BQM):

These happens even though I am not using it during the day. I'll see if it happens again today. The large yellow spikes are me doing the odd speed test. Exchange VP is green.

Do any of you have the BQM monitoring you WAN IP latency for comparison?

I have used the BT test site but predominately the speedtest.net site as it is quicker. The BT test usually has me waiting for a couple of minutes and then often times out.

On all the tests my ping is consistently 80-100ms. The up link speed is consistently 0.5Mb/s to 0.6Mb/s no matter if my download speed is 4.8Mb/s or 0.3Mb/s.
My exchange VP is and has been consistently green.

I am coming to the conclusion that it is a ISP bandwidth problem although ADSL24 tech support have told me they have been unable to detect any problem.

This is mine from last night!

I think you may have given the "live" link, but anyway, that's horrible.

I have managed to run the full three BT speedtests which seem to indicate that the problem lies within the BT system and not with the ISP, (third test is as bad as the first two).

Good news, no need to change ISP, bad news, I have to wait for BT to increase capacity down the line or for hell to freeze over.

I've had the same problem with ADSL24/Murphx in the last couple of months.

Speed is very slow at peak times, but fine off peak.

A colleague with a different ISP on the same non-LLU exchange doesn't seem to suffer the same problem.

Could still be the exchange, just on a different VP.
