Don't screw with your ISP router
I have a Sky Q router which does some really counter-intuitive things in order to support its wireless mesh for delivering TV all over your house. If I did change its default passwords and something weirdly unexpected happened then I could be forced to spend all afternoon getting the answer out of their call-centre, and frankly I'd rather not.
While I'm here, if anyone knows how to configure a Sky Q router to allow its wirelessly-connected devices to talk to ethernet-connected devices please kindly let me in on the secret.
