I bought the Chromecast, but cannot get Netflix working on it as I have setup Unblock-Us etc; but my CG3100 Router cannot be DNS changed at all. This is a known issue stoping lots of people; I am curious to see if there are any other options? I can now watch Netflix on my computer; and phone. But cannot stream it to my TV.
When I cast it to the Chromecast it says "Sorry, we are not available in this country." I have added the Static IP (8.8.8.8) to block it, still nothing,
Sorry if this doesn't answer your question but I never had to change the DNS on my router ever when I needed to watch something on netflix. I would always change the DNS either on the ipad or xbox one. Or do you need to do it with a chromecast?
