Do any of you with working R7000's have Chromecasts? I see one user with a Galaxy Note 3 has chimed in with the same problem as me.
I have a Chromecast, and I played around with it last night before I posted my reply to make sure it was working. I pushed a few YouTube video from my Nexus 7 and didn't have any issues or disconnects. How long are you able to use it before it drops? Or, is it just MIA the next time you try to connect? I just checked, and mine is still connected almost 24 hours later.
