Google Chromecast can be set up by going to the setup page on a supported device. But in technical terms, what is actually happening on your device that configures the Chromecast dongle? For instance, if I have a WPA secured wireless AP, how does the dongle "listen" for configuration information?
afaik the only automatic way of doing this is Wi-Fi Protected Setup (WPS). However, that wouldn't require an additional device. So it seems like Google is doing something else.
2So, does it mean I can't setup a chromecast device using the desktop which doesn't have wifi adapter? Also is it expected a network disruption in the device which is setting up the chromecast? because it would be disconnecting from the existing access point and connecting to chromecast's ap? – Arunprasad Rajkumar – 2014-11-16T15:11:09.913
1Great. But, however, this leaves me with the question: "How do I connect it to a new network, or change the password if my AP password changes?". Does chromecast have a "reset" mode to get it back to acting as an AP directly itself once again? – Jrop – 2013-08-01T20:13:32.687
2I think it will go back to that mode if unable to connect to the existing wifi. – zimmer62 – 2013-08-07T14:52:57.223
1Google should have informed the user that the setup device (phone, tablet, PC, etc) has to connect to the ChromecastXXX AP first and do the initial setup first before it moves to the other Wifi networks. Man, if they mention that it acts like an AP initially, it would have saved a lot of time. To me, it is outright stupid on their part. I have a WRT54G and the hardware+firmware are supported according to Google but I couldn't figure how the Chromecast access my AP/router without knowing my WPA password. Thanks for the headup. – None – 2013-11-28T16:07:18.397

To change the wi-fi network that the Chromecast is connected to, you need to perform FDR (Factory Data Reset) on the Chromecast and run setup again. See https://support.google.com/chromecast/answer/3210071?hl=en.
