line stats and speed problems

Hi all,
just looking for some advice. My ADSL was activated yesterday and since then have had really poor speeds, I'm currently running BT Speedchecker tests and the most I have had is around 600K (Im on Premier 2MB)
I was also informed by PN that BT have said my service will only be 1Mb. From my router I get

SNR Margin 39.0dB
Loop ATT 33.5dB
Are these sufficient results for 2Mb and if so is it BT that are limiting me to 1Mb?
Thanks in Advance for your replies.

Those results are fine for 2Mbit - mine are much lower, but it still works.

Does your router / modem tell you the current sync speed? It should be something like 2 or 2.2Mbps.

Poor results on the BT speedtest can be an indication of a congested exchange / virtual path. What does Usertools say about your exchange?

Hi, thanks for the reply,
the router shows Upspeed 288000 Downspeed 1152000

The exchange was only recently enabled(last week) and there aren't that many people on ADSL yet(According to BT Engineer)
I was converted from ISDN yesterday, dont know if that has any bearing on it?Huh

Waited with matchsticks in the eyes and ran the BT test. 707Kbps, great, need to surf at 2-30 am to be 3/4 of the 1Mb bandwidth.
Unfortunately it seems I shall need to move ISP.

I'm surprised you were only enabled at 1Mbs because your stats suggest 2Mbs should be possible. I would raise a ticket and complain and get it investigated.

I have raised a ticket and PN are requesting a line check, out of curiosity are these speed check results (BT speedceck) what would be expected from a 1Mb line?

No. Not knowing you were on 1Mbs I would have assumed you were on 512K with most of those speeds. 1Mbs lines should be getting 900->950Kbs and possibly more if you are lucky.

What MTU and RWIN are you using?

Not sure what MTU and RWIN, how do I check this? I assume from your reply my connection is not as it should be.

Thanks for the reply

To add to this post. PN replied to my ticket stating these figures were within normal parameters!
