For a long time, several years, I have experienced drop outs especially when raining/damp.
I wonder if the reason is my junction box:-
This box is just under the plastic gutter of my house. I do not know how long it has been like this but could be a number of years; next doors tree brought my drop wire down and this may be the connections after that incident It was BT who replaced the drop wire; I assume as I was on holiday at the time.
Should I get Zen to call in BT to look at?
