you can ring or wait here for VM to pick up the thread
your post seems to have been moved so is slightly out of content but is this a quick install that you cannot find an internal box - if so
not all installs have an internal box
start outside and look for the external wall box - 6" square ish usually on wall facing road or pavement - brown or grey usually - follow any cables that come from it and go inside - if there are non look inside opposite external box as they may just have drilled through wall - as said it may just be a cable rather than an internal wall box
if you find a cable you need one of these to attach the cable that came with the quick start kit
I am using the external box, the cable was already in place in my flat so no need for an engineer to come in the end :). just one question, do you know if you can use this cable for both the wifi and the tv ?
