Now more frequent disconnects after "boost Engineer"

[#1]

You very kindly arranged to have a "Boost" engineer visit me to check out possible causes of frequent disconnects.
He couldn't identify a problem, but installed a new wall socket with direct connection from my router which removes the need for a filter.
However, since then I have still had many disconnects, which seem to be increasing in frequency. It's affecting work and leisure, with streamed TV often being interrupted.
To summarise, I've gone down all the routes you suggested to get this fixed, and I'm wondering where I go from here.

Is there noise on the line?  Dial 17070 option 2 using a corded phone plugged into the master socket.
Are the disconnections associated with using the phone?

It doesn't look pretty from here.

I can see we've sent you a new router and that should be with you in the next few days.
Let us know how you get on.

That looks really grim!
@Spacie,
Any improvement with the new router?  Can you please answer my previous questions?

@CRT,
RADIUS plot improved any?

Better, but still not perfect.

I've not got the history of the case, assuming everything internal has been done, I'd suggest another engineer or possibly an SNR increase/interleaving.
