I have an extra router laying around (Netgear N600) and I am thinking about setting up a little wireless network in my RV to use a Roku and Sonos. The router has a DNLA server built in with USB ports. If I install the router, plug in a USB hard drive and use a Roku streaming stick should this work? I guess my biggest concern is that the router, hard drive, and Roku will power on and off on a regular basis when the trailer is hooked to shore power and when it's unplugged. Should the router and roku retain their settings?
