I have an ADSL speed of 500-600kbps which not uncommonly loses sync.
I wanted to try and use an i-plate to improve the line but I cannot find my master socket - all the sockets in the house are un-branded and indentical.
The house was built in 2008 and outside there is a small grey BT openreach box. On the other side of the wall is a socket but it doesnt have any of the 'usual' master socket features - no obvious input and then extension output points just one phone cable coming in. None of the other sockets seem to be masters either (have removed them all to look at cabling.
Are modern houses phone lines wired differently to the traditional master socket design?
Is there any way to isolate the DSL signal at the grey box to improve line quality by isolating it from the rest of the extension wiring?
