Draytek 2762 Stats Help Please!

Hi Guys,

Currently having a few issues with my supplier, so one thing they advised was to do away with the old OR ECI modem and replace it.

That i have done and am now running the Draytek.

Would someone be kind enough to give me a rough idea what i am looking at as it appears my actual rate is higher than my attainable amongst other things!

Thanks

dose this help?

Brilliant, thanks for that.

I have just done another screen shot and i think things seem to be getting worse?

The line has had interleaving enabled.
This adds 8ms latency but can increase stability considerably.

The line will probably settle where it is for a while.

It's all downhill from then though as crosstalk interference will eat away at your sync speed over the coming months/years.
