Internet speed

Making the most of Superfast2

3: Seeker



I have recently upgraded to superfast 2 (on Monday) and probably had overly high ambitions of speed improvements i may see based on the bt wholesale checker for my line. I have posted the stats from the checker and the router below, but i have a few questions that hopefully people can help me with

. Is DLM reset when you upgrade package and therefore is the line in a 10 day "training" period and could improve over that time?

. Would a third party modem / router improve my sync speed?

. Am i reaching around what i can expect from my line or could i hope for more?


Many thanks all

I don't believe DLM would be reset on upgrading. I think DLM on VDSL starts high and works down, unlike DLM on ADSL which starts low and works up.

Either way there is not much room for improvement on those figures.

Have you tried with it in the test socket?

Thanks for the response. I've not tried the test socket yet. I'll have a play this weekend when I have more time and post any changes.
