About a 5 months ago I started getting random disconnections on my plusnet dslmax. It wasn't until plusnet phoned me to say they'd noticed an unusually high number of disconnects that I started trying to diagnose the problem.
After changing filters/router/cable plugging into test socket I found that the disconnections were happening whenever the phone rang. I pretty much gave up, but today I decided to have another look.
Firstly, my line stats as normal:
Router stats before.
Plusnet told me that my connection had been stable and fast (I live less than 500m from the exchange).
The flat I live in is a converted office, it has phone points everywhere. I noticed, upon taking the covers off these boxes, that the BT wire ran in, spurred off to the main phone point then also off to this massive white box. No other phone points are being used.

Big white box of doom
So basically I cut the wire running into the Big White Box of Doom and now my stats say: THIS. Basically it dropped my attenuation from 23dB to 18dB, but my sync rate seems to have dropped?
AND the phone just rang and it didn't drop my connection. Was it a fluke? Did i do the right thing? And what the **** does the Big White Box of Doom do? (Apart from drop my connections apparently).
Thanks for any help!
