Chromecast will not setup or connect

I am new to the world of Sierra. I have an MP70 and for the life of me, I can not see it when I am connected to my MP70. I also can not set it up when connected to it. I know the chromecast works fine as I can set it up on my craddlepoint and it connects but just not with the MP70. Ideas?

Please make sure WIFI on MP70 work correctly. You can use your laptop to connect to your MP70 via micro USB port and go to ACEmanager to configure WIFI for your MP70.
