My Chromecast was working fine in another location with a different router. Brought it home, and am trying to use it through my Airport Extreme Base station. I am using the Chromecast App on my iphone as the go between. I can get the dongle to find the base station, but it cannot connect to the internet through it. I have found several potential fixes, but they seem to all be different. Before I start changing things I do not understand, I would like to at least know I am on the correct track. Can anyone give me step by step instructions that will work?
