I don't believe this! I lost internet momentarily again today and DLM has changed my Target SNR from 6 to 9, so my sync speed is now just over 5 !!!!
I used to get 3db and sync of 6.7 (I had this for years with no problems) I don't understand my line normally stays up anywhere from 7 days to 21 days before a re-sync. Which took less then 30 secs, so I don't understand why the target margin would have increased by another 3DB!
I am wondering if this is to do with the fibre work in my area. Is there anything I can do to get my speed back?
