Chromecast 3rd generation problem

Community Member

Just got a new chromecast 3rd gen.

Connected the device to hdmi port on the tv, ac connection as well.

installed Google home on my android cell phone, and started to setup the device.

Google home detected the new device, configured, connected it to wifi, updated the sw, and ends the setup process.

After that I tried to connect and start using it, and on Google home app, i'd "click" on the device name newly configred, first a "Connecting..." message appear followed by a  "Not Available". (Can't see device on this WI-FI network...).

I doublechecked my phone is connected to the wifi, and get back on google home and check on settings/rooms.../device/device settings/devicename/device Information/wi-fi/ and is the same as in my phone.

The led in the chromecast is white.

I'd restarted the wifi modem, inmediately in the TV  shows chromecast trying to connect to wifi, eventually connects.

And then it begins...device not available on Google home.

I already reset factory 3 times, and also in one of them tried to configure it with an iphone...and the story is the same.


Can someone help me with this issue please?

Any help will be much appreciated.

Hello Adrian01,


Thanks for reaching out to the Chromecast Community and I'm sorry to hear that you're having an issue with your Chromecast. Let's sort this out.


A few questions: what's the LED status on your Chromecast (solid or blinking)? How far is your Chromecast from the Wi-Fi router? Are you using a dual band router?


Try these steps:


  1. Make sure the Chromecast device is within 15 to 20 feet of the setup device and the Wi-Fi router.
  2. Toggle Wi-Fi off and on from the setup device. Once on, make sure the phone is connected to the same Wi-Fi network as your Chromecast.
  3. Reboot your mobile phone.
  4. Close and then reopen Google Home app.
  5. Turn on Local Network Access for iOS devices. Here's how: Go to phone settings > Tap Privacy > Local Network > Make sure it is turned on for the Google Home app.
  6. Use a different supported mobile device.
  7. Do another factory reset on your Chromecast, then try to connect to the Chromecast SSID. Here's how: Go to the phone settings > Open Wi-Fi and connect to the Chromecast SSID (Example: Chromecast1234, Living Room TV, Bedroom TV, etc.) > Go to the Google Home app and try to set it up again.

Let me know how it goes.
