@Andrea707bow Only had a visit once same type off circumstance, but they where Contractors direct from EE that were sent, and are NOT allowed to check or mess with anything, that way they had NO method of checking any fault condition , so about as much good as a chocolate teapot, to confirm there was a fault the Engineer had to connect onto the router, when he grabbed the card to do so, got confused when none off the details matched to which the would not as i had changed all three off them, SSID, wi-fi password, and the Router password. Had to give the password to one off the engineers to do his check via his mobile, yes confirmed there is an issue and we will organise OR to send someone to take a look, just shrugged the shoulders and what else could one do.
As you know they have been and where expected then nothing should be going on to have you worried, depending on what router you have and how it was setup originally password for the wireless may have been different, making the password change would have effected ALL your other devices unless you only have the one.....
