Thank you for helping me resolve the IOS issue with casting.
I have a new problem. About 3-4 minutes into the casting, the connection begins to break up and ultimately disconnect. My setup is simple and should provide the most optimum performance environment for both the 350 and Chrome adapter. Both are hard wired into a 10/100/1000 router using Chrome's (www.chromecast.com/ethernet) adapter. No WIFI involved.
No matter what I do, 3-4 minutes into the cast the connection begins to break down then ultimately disconnects.
