In that case I'd ask your ISP to do the SNR reset. Good luck!

just thought i would try one last speed test before ringing the post office , and my ip profile has decided to increase to 3500 many thanks to you both for your help, much appreciated

The wonders of the BT Profiling system!

Just out of interest, post the URL of what samknows says about byour exchange.

hi there

i am on a market 1 exchange ( live in a small village) so no cheap packages as such (no llu),

although i am very happy with the Post Office with home phone and broadband extra for 26.05 a month, no one can come close to them in terms of price,features and usage on a market 1 exchange. i have never seen slow speeds in the year or so i have been with them even at peak times.

once again many thanks

well over night my sync dropped to 3964 which means i now have a profile of 3000 again

i re booted this morning at 7.27 am with a sync of 5088

her are my current stats, wounder why i had a reduction in sync over night ? , many thanks

The overnight re-sync is odd. If it happens again, please get the stats before rebooting.

Do you know whether you have a static or dynamic IP address?

It might be useful to download RouterStats and keep track of what your noise margin is doing. Set it to save graphs, and set the sampling interval to the lowest, I think that is 5 seconds. Setting it to log to file is a good idea too.

The good news is that your 5088kbps connection will get an IP Profile of 4000kbps if it is stable.

hi there i just had a look at my starts as my internet was running slow , here they are

ADSL Link Downstream Upstream
Connection Speed 5088 kbps 448 kbps
Line Attenuation 39 db 10.5 db
Noise Margin 0 db 23 db

the noise margin of 0 db looks concerning ? does this mean the router is due to re sync itself at a lower sync rate? , many thanks

just done a re sync here are the stats

ADSL Link Downstream Upstream
Connection Speed 4128 kbps 448 kbps
Line Attenuation 38 db 10.5 db
Noise Margin 5 db 24 db

this is the kind of sync rate ( the low four thousands) i get when it will stay at that for weeks and weeks with no problems

Yes, you have a highly variable noise margin, so may be best (for now) settling for the 4000+ mark to get a 3500kbps profile.

It would be a good idea to install RouterStats as I suggested. That is really good for spotting patterns in the variation, and may even give a clue to the cause. It could very well be something under your control and easily fixed, so you could get a 4000 or 4500 profile. A line the length of yours ought to be able to.
