Hi all,
I have seen multiple articles and issues wrt Chromecast WiFi connections to Mikrotik devices and decided to share my experience so far on my blog http://lenjoubertblog.blogspot.co.uk/20 ... eless.html and to start a single topic for Chromecast related issues.

Hope it helps someone out there.

Summary: Provisioned an SSID on one spesific radio/band (5ghz-onlyac) for the Chromecast 2 to connect to.
