checker speed prediction

As our exchange slowly trundles towards 21N etc (rfs end of March), the checker speed predictors which used to give me an estimate of about 14Mbps ADSL2 downstream, have suddenly started quoting me 6Mbps.

I'm currenly on a sync rate of 7392, with a stable line profile of adsl6500, and have been for a few years. I know my current router (Draytek 2600G) can't handle ADSL2.

So if I change to a modern router ADSL2+ enabled router, would I be likely to see more speed both from the estimators and when the upgrade goes live ?

what's your downstream attenuation and snr margin ? there are predictors around for the ADSL2+ expectation based on that.

I would expect some gain if you're close to the max speed now. You'll get the speed it can achieve regardless of what checkers say. They are only pre-sales estimators not part of the control system.

My router stats are

http://www.dslzoneuk.net/maxspeed2.php suggests 14-18 Mbps on ADSL2+.

Your line appears to be interleaved (7616kbps sync). Do you have any noise on the phone line? Seem to be more errors than I'd expect.

You might want to blur your IP address in that jpeg.

eta: ignore the error comment, nothing wrong for your uptime.

I've always wondered about the errors, but I'm not sure how to test the line for them, apart from the router stats, to see if there is a fault.

Thanks for your help

the errors don't look too high to me, for the uptime. The SNR margin of 12 dB points to more speed being available on a faster ADSL standard.

Is that with it plugged in the test socket ?

No it's just plugged in to the upstairs room socket where it's always been.

I've got a feeling that Zen may have interleaved me when a treadmill was electrically interferring with the router ages ago (it used to knock it off line)

the test socket may show a bigger margin and hence more potential speed.

So a new router will be in order when the exchange is upgraded.
Any faves ?

might do better in the DSL Hardware section, list your requirements as well as ADSL2+ from BT.
