I joined TT when fibre first became available in my area in August 2015. The speeds were the maximum they could be at 79999/19999 down/up.
The speed is slowly dropping from this perfect score. It seems to drop when I get an unexpected router drop and then never returns to the previous speed.
The router stats are currently 67347/19999. The maximum downstreamm has decreased from over 120000 to 92048.
Yesterday the connection was around 69000 down but there was a router downtime and it rebooted to 62000 down. I did the 30 minutes router off to try and resync the speed at a higher number and it did reset it to 67347.
The questions are: will the down speed continue to degrade, and is there anything I can do to stop or revese this speed loss?
Current statistics of router in the spoiler...
ps If it helps I can pretend to be angry and do some *rage* or threaten to leave... 
edit: I am using master socket, wired connection.
