Have a look at: http://i2.photobucket.com/albums/y31/Polchraine/TBB/...

The first is a 50MB, second BT speedtest and third a TBB speedtest. The comb at the top (switching between two levels on alternate samples) is something that I cannot over come but all three show very similar download speeds. There are two other PCs working on this liink and I also have a couple of applications open that will be using some bandwidth.

The shape is reasonably regular, no large drops or dips and I am happy with what I see - compare those to yours and you can see the potential issues you have.

Thanks for this MHC
Will try again later

I suggest late evening as that tends to be a quiet time and just before those who have unlimited off peak start their large download at midnight.

Have to be on an early flight... sorry
Thanks for help..
I've agreed with ISP that I'll pay £15 to migrate to ADSL2+
No monthly charge change..

Hopefully will improve!

today though...
Download speedachieved during the test was - 5669 Kbps
For your connection, the acceptable range of speeds is 600-7150 Kbps.
Additional Information:
Your DSL Connection Rate :8128 Kbps(DOWN-STREAM), 448 Kbps(UP-STREAM)
IP Profile for your line is - 7150 Kbps

Have a look when you get back ...

I still think congestion is the issue but moving to 2+ may move teh network resource too but let's wait and see.

massive improvement!!

Sync speed good, but

In reply to a post by peterhou:

I would expect closer to 16.5 Meg.

Also Down NM looks very low. Could indicate bad line and prone to discons.

Depends on when the line was synced and when the stats were taken.

Quite possible to have a line sync a 3 or 6 dB mid-morning and to take a snapshot at some time overnight when the margin will have dropped.

I considered that but still think it's a large drop overnight even from 3 dB and particularly from 6 dB

I have seen many vary by 5 dB and more even up to 7dB ... mine was about 5dB typically and occasionally 6dB.
