Bt infinity 2 speed increase

Hi people. Been living in my house now for 4 1/2 yrs and I have enjoyed a reasonably stable 68 down 20 up on infinity 2. However in the last week my hub 5 is now showing 76 down and 20 up. Bit of a speed jump thats never happened before. Anyone any ideas? Seems stable at this....fastest its ever been....

Perhaps the Openreach DLM has lowered your sync-time noise margin. It can now set 5db, 4dB or even 3dB on stable lines, instead of the original 6dB that it was for years.

Quite possibly as my noise margin is running at 4.7 atm.

If it's a Hub5B, could G.inp have just been enabled?

There are two other possibilities. One, as MrGimper says, and the other that your cabinet had a power cut and you were one of the early resync's.

I would tend to leave it alone and enjoy. It may do similar again soon and lower it to 4dB, or noise/errors will rebuild and cause it to revert to how it was before. A single re-sync in daylight hours might answer the question, but would either disappoint if it was a power cut causation, make little difference if it was G.INP kicking in, or slightly delay a further drop to 4dB with higher sync still if it is DLM seeing how low it can take it with acceptable error rates.

Well I will see how long it lasts. The hubs last update was on 13/7/17. So I will see what happens. It has been resynced in last 4 days. (Wife pulled plug accidentally) still running same.

I have Infinty2 80/20 and have also seen an increase albeit slight.
I have a separate modem and also the first router that BT has not had any reason to change after about 3 years with them.
Maybe OR have been very busy at the cabs,

No, they haven't.

Well, in essence they have.

The 3db roll out is still on going, so whilst they may not have been busy at each physical cab, they certainly have been to develop, test and implement it.
