I have what I think is a Chromecast-1 (round black body with a USB port for power and a flat cable to connect to my TV's HDMI input box. My TV is a Samsung Smart TV. When I first installed the Chromecast, it worked just fine. Then I upgraded to fiber and changed my network name. Now the Chromecast says it can't connect to Wi-Fi and suggests that I go to chromecast.com/help. I am pretty sure I did not use an iPhone to do the original install and I can't find anyplace I can attempt to log-in to my account. Would it be possible for me to create a NEW Chromecast account using the original Chromecast unit? If so, HOW? If you have any other comments or suggestions I am eager to hear them.
If you've already changed to a different Wi-Fi network, try these steps:
If these steps above don’t solve the issue, you’ll need to factory reset your Chromecast, then set it up again using your new Wi-Fi network and password. If you're using Chromecast with Google TV, follow these setup steps instead.
Instead of factory resetting your Chromecast, if you're comfortable changing your router settings, you can change your new Wi-Fi network name and password in your router's settings to be the same as the previous ones. Your device should then automatically connect to the Wi-Fi.
