Can't say that my gateway has ever gone down on the wired side. Or even that wifi had problems for nearby devices - it is just weak in other rooms. You can fix that with a wifi access point or a router configured as an access point and connected on its LAN side without introducing the problems of a separate subnet. I don't see any real win for a 2nd router acting as a router - but using a wired connection for anything acting as a streaming server is certainly a good idea.
