ok there is a ext cable in main bedroom so possibly one of the cables goes upstairs and the other to lounge.
So i will take a blue out of slot 5 and the other colour from slot 2 making sure the are both coming from same main cable if that doesnt work try the other cable pair in those slots.
Does it matter which slot they go in for ext as i have a and b on there.
Yep, that's right. No, it doesn't matter which colour goes where as broadband is not polarity conscious.
brilliant you have been a massive help, think i have found which cable is which took ext plate off upstairs bed and slot 2 has a blue and white cable so guessing slot 5 in lounge should be the plain white, need to move big cabinet in front of it first but at least i know what im looking for now thanks.
