you have a connection speed of 31mb which is above the guaranteed speed - remember the guaranteed speed is not a download speed but a connection speed so results from btspeedtester are immaterial

 

if you can get noise margin dowmn to normal 6db then your conenction speed will move closer to attainable speed

If there is an issue that has caused the DLM to drop your speed and increase your noise margin (the two are linked) then unless the issue has been fixed or gone away of its own accord then a DLM reset wouldn't really achieve much. It might increase your speed for a few days until the DLM quite sensibly decides to take action again because the underlying problem is still present.

 

If the engineer finds a fault and fixes it then he will normally request a DLM reset. It makes sense to request it then if a fix has been applied, rather than having to wait for the DLM to automatically recover after a few weeks of issue free connections.

It is not the same for everybody. When you sign up to BT they give you a minimum guaranteed connection speed for your own line.

40Mbps is the maximum connection speed on Infinity 1 40/10.
The guaranteed minimum connection speed is line specific as gg30340 says. It's normally on the order confirmation.
