Hoping someone can confirm this for me either way please.

We have recently installed ADSL broad band. The problem we have is we only have 1 phone socket.

This socket has one phone running from it plus a splitter which then leads to 4 (!) sky boxes (These all have microfilters on them).

The broadband works fine until the extension lead which goes to the different sky boxes is connected. As soon as this is plugged in the ADSL signal drops out.

I am assuming this is because there is to many things for the phone line to handle? We Will the additon of a Ren booster on the main socket allow us to run everything?
