I recently switched to at&t fiber and now my chromecast wont work with the new wifi. I go through the google home setup and it gets stuck on the connecting to wifi screen. I've already reset it too and same problem.

This usually happens when the new router (like AT&T Fiber) is using a different frequency band or network isolation setting. Try these quick fixes:

  1. Make sure your Chromecast and phone are both connected to the same 2.4 GHz or 5 GHz band.

  2. Open your router settings and disable AP isolation / client isolation if it’s on.

  3. Forget your old Wi-Fi in the Google Home app and run setup again.

  4. If it still fails, factory-reset the Chromecast and set it up on the new network from scratch.

These steps usually resolve connection issues after switching ISPs or routers.

Hello @adan92590,

 

Thanks for the recommendations @jennyjohn235.

Thank you for posting in the community. I understand that your Chromecast is having trouble connecting to your new AT&T Fiber network and that the setup process is getting stuck even after you've already performed a reset. Let me help you with this.

To give you the most accurate solution, could you please provide some more information about your devices and network?

  • Could you please confirm the specific model of your Chromecast? (Please visit our Help Center to learn more about Chromecast and Google TV Streamer specifications).
  • What TV brand and model are you plugging the Chromecast into? (A photo of the label on the back of the TV or the router can be very helpful!)
  • What device are you using to complete the setup (your phone or tablet), and what is its operating system version (iOS or Android)?
  • What is the brand and model of the modem/router combo unit that AT&T provided you?
  • How far is the Chromecast device from this AT&T Wi-Fi router? (Bringing them closer together temporarily can help rule out a range issue).
  • Can you also confirm with us how you reset your device?

Getting these details will allow us to check for known conflicts between your specific AT&T router model and the Chromecast and guide you to the exact settings we need to change!

 

Regards,

Kevin
