Thanks for posting and sorry for the late response.
A few questions — what exact message are you getting when pairing the Chromecast to your new network? How far is the Chromecast from your new router? What mobile phone are you using for setup? If you changed your WiFi network and your device isn't currently connected to a Wi-Fi network, perform a factory reset and set up your Chromecast on the new network. You can also check this support website article for more info.
Let me know how it goes.
We haven't heard back from Wasim, and it's been a few days, so I'm locking the thread. As always, feel free to make a new thread if you have any more questions or concerns.
Thank you for your help, Jennifer!
