I have a question for our experts, inspired by another current thread that I don't want to hijack...
Since my router is plugged into an extension that isn't used for a phone, can I ...
Q1) remove the BT phone socket and it's trailing filter, and replace them with a directly connected RJ11 faceplate for the router with no filter at all? And...
Q2) am I right in thinking that getting rid of the that filter may, if I'm lucky, make a small but measurable improvement?
As background, the router sits on a high shelf in a built-in cupboard. I had already reasoned that the existing phone wiring, installed in the wall cavities when the house was built, must pass right behind it. So I was able to dig a hole in the plasterboard and splice a new socket into the existing wiring, right next to the router. But there really would never be any sane reason why anybody would ever want a phone in that socket, so replacing it with an RJ11 is a tempting idea.
Anybody with an eye for detail may notice that I'm contradicting myself, since I'd said elsewhere and in other threads that an extra filter seemed, against the odds, to actually improve my line. That used to be consistently the case but, following some detailed wiring improvements the other day which I won't bore you with, it's no longer the case. I now find the fewer filters I have, the better it gets.
