Hi pauline4,
Thank you for reaching out to the community!
I understand your Chromecast is unable to complete the setup process because it’s stuck on a 'Connection failed' error, and you're seeing an alphanumeric code on your TV screen. Don’t worry; let's work together to find a solution!
Please answer the following questions to help me investigate this further:
- Which Chromecast model are you using? You can use this help center as a model reference: Chromecast and Google TV Streamer specifications
- Are you using the latest version of the Google Home app? If not, this Google Nest Help Center article provides helpful instructions: Update the Google Home app.
- Are you using an Android or iPhone smartphone to set up your Chromecast?
- Is your phone’s operating system updated to the latest version?
- What is your TV brand and model?
- What is your router brand and model?
- Who is your Internet Service Provider (ISP), and what is your plan's speed?
- What is your location type? (e.g., Apartment, school, hotel, etc.)
- During setup, does your Wi-Fi network name appear in the list of options within the Google Home app?
- Does your Chromecast currently appear in the "Devices" or "Favorites" tab of the Google Home app?
In the meantime, I recommend following these steps to improve the connection:
- Ensure your Chromecast is connecting to the exact same Wi-Fi network as your smartphone.
- Move your router within 15 to 20 feet (6 meters) of your Chromecast.
- If your router supports both 2.4 GHz and 5 GHz, try connecting your Chromecast to the 5 GHz band for better performance.
- Regarding the code on your TV screen, please verify that it matches the code shown in the Google Home app on your phone. If they match, confirm it on your phone and tap "Next" to continue. For more details, check out this interactive set up guide.
Please share those details with me and let me know how it goes!
Best regards,
Virna
