Thanks for the help! I have Pdanet installed on my gs3, but I haven't been able to set up the Chromecast without a third device in the mix. Using my work laptop is out of the question since I can't install the Chromecast app on it. I don't like to bring my personal laptop along with me on business trips since it's kind of bulky and heavy for a 2 night trip. I have an old Android tablet I can bring along with me to set everything up and control the Chromecast from but it would be awesome if I can get it working with ONLY the gs3 and Chromecast. Is there some way to make that happen? Or will I need a third device in the mix because the gs3 cant be a hotspot and controller at the same time?
A computer with wifi (a computer just jacked into a router in wont work) is a necessary part of setting up chromecast to a new network.
edit: actually i might be wrong on that, testing something now

Okay, this is what I just did.
I turned Wireless Tether on my phone on. This means wifi can't be on at all and thus your phone can't be on the same network as the chromecast, and won't be able to control chomecast.
BUT
I downloaded the Chromecast app from the playstore to my Nook HD+. It found the Chromecast on my home network and I tapped on it, and saw my Chromecast on my home network (which the nook was also on). I was able to change it from my home network to my phone. This changed the network both my Nook and Chromecast were connected to from my home network to my phone network. I just chromecasted netflix from my Nook to my TV via chromecast fine. So basically I was able to set it up on a new network with no need for a computer.
So if you are traveling, I believe you are going to need to set up your Chromecast to know your phone's wifi network/password before you go. Why? Because my Nook (or your tablet) can't change the network of the Chromecast without already being on the same network. But at this point, I could now take the three devices anywhere now, plugging chromecast into a TV, setting up my phone to tether, and using my tablet to control it.
Annoyingly, once I turned off tethering, the chromecast borked and I had to re-run setup to get it back on my home wireless network. So, it doesn't seem to save multiple networks, unless I did something wrong.
