Thanks for reaching out and I'm sorry to hear that you're having an issue setting up your Chromecast. Let's sort this out.
A few questions: How far is your Chromecast with Google TV to the Wi-Fi router? Are there other devices that can connect to your Wi-Fi network? Are you using a dual band router?
Give these steps a try:
Make sure the Chromecast device is within 15 to 20 feet of the setup device and the Wi-Fi router.
If you're using a dual band router, check if you're connected to the correct network connection (2.4 GHz vs 5 GHz).
Check if the router has a hidden network name or SSID. If the SSID is hidden and not broadcasted, you will need to manually input the network's name and password.
Connect to a mobile hotspot to isolate the issue.
Force close the Google Home app.
Reinstall the Google Home app.
Reboot your Chromecast, mobile phone, and Wi-Fi router.
