So recently my Asus ac88u gave up the ghost. It was my first multi switch router. This was a rude awakening. Having all of our local traffic completely dependent upon the router means nothing works anymore. My idea is if I wire the entire local network to a managed switch, then the switch to the router, in the event of router down situation the local devices will still be able to talk to each other. Game machines can still play LAN, tv's can still stream from NAS, and so on. Correct me if I'm wrong but, would I set all the clients to use the switches IP as their gateways and set the switches gateway to the routers IP? Or am I about to embark on a mysterious and wild adventure into networking? I just want to set it up so that in the event of a router down situation the only thing the local devices lose is internet but not intranet (?).
