Connection was perfect before christmas 80mbit down constantly but one of our children unplugged the router instead of the christmas tree lights 
which caused dlm to resync at 69mbit. Over the next week the line rose steadily to 80mbit again as you can see from the stats but throughput is stuck at 60mbit going through a cat 6e cable directly to the router.
I have this problem constantly with dlm as it seems to get stuck, i spoke to tech support who done a gea test and my upstream and downstream are very good. Min speed was 53mbit max 79 average 76 which isnt right at all.
This is what is showing on my account on the plusnet side
