Have downloaded and installed the latest DGteam software to my gt and left the router running, regardless of what BTw are doing, if anything.
The other day my snr dropped to 2.5db and this is when my connection speed increased,  but alas the bt hub reset itself after a while.
Thought I'd try to use the snr fix, to see if things are better at night time. I gather BTw 's target snr is 6db, so I have the router at 100%default at present, and its plotting 6db+/- 0.6 atm. Plotting it on routerstats 5.8.
Anybody give me a heads up on using the snr fix correctly pls?....not certain I've grasped it all yet. ::)

hi
Yes the default Target SNR margin is 6db. Some lucky peopple may tweak down to 3 db and still have a stable connection with improved Synch speed . Some people may tweak upwards to get a more stable line sacrificing synch speed for stability (gamers may prefer that to having interleave on ). Others will tweak down from an enhanced Target SNR margin (caused by some now fixed line problems) to regain some synch speed.
So if your line is stable at 6db then it is probably best to leave it at that . Don't forget that SNR margin is just one of the stats to be considered .

Thanks for that Jeff, are there other useful tweeks that can be done in the DGt settings as well?
I did wonder about trellis but left well alone, till I grasp it more.

Hi
Status: ShowtimeRetrain Reason: 1 . I think that is just that you lost synch its as a result of Showtime Drop Reason:   1 .This is Not the same as the 10 day training period

I did wonder about trellis but left well alone, till I grasp it more.


Thanks Jeff
It did lose sync, as I tried out the snr tweek!   :blush:
Can you offer any advice re- my post, I understand if not.

Thx
Appreciate the help
Roger
