Brand new Chromecast, setting it up and attempt to connect to wifi, App on TV screen stays "Connecting" and eventually times out and says couldn't find network. iPhone app shows the same. Router actually shows the device is connected and I can see data activity for the past 28 minutes of so and is still connected. I have rebooted everything several times, read all the previous posts and still can't find an answer. It shouldn't be this hard. I have owned the device for a couple of hours that I have been trying and about to take it back for my money. HELP!
Update, left the system running overnight and viola, it was working this morning. Completed the setup and all is working. Suspect it updated overnight as the traffic from it over the internet was noticeable.
It looks like Crasharo was able to resolve the issue, and it's been a few days, so I'm locking the thread. As always, feel free to make a new thread if you have any more questions or concerns.
Thank you for your coming back with your solution, Crasharo!
