unstable connection with regular drop outs

For the past few days my usually reliable connection has been poor with frequent total loss of connectivity in the evening. 

I set up a think broadband bbqm yesterday to monitor the connection in anticipation of having to fight with VM to get it sorted.

I'm on M600 via Vroom package and use my SH3 in modem only mode and have an Asus RT-N66U handling wifi / networking as I found the sh3 was poor when installed.. 

Link to the bbqm:

here is the info from the SH3:

Re: unstable connection with regular drop outs

Upstream power looks to be too high - Forum staff should get to this and book out a tech!
