Chromecast hd won't connect to network

[Fransafe]

Got chromecast hd - set up fine👍.

Bought another for upstairs tv. Exactly the same model.

Started to set up second chromecast on other tv. For as far as looking for network - All ok finds correct network - but it won't connect to wifi network.

I've tried: factory reset of chromecast:  switching off and unplugging both chromecast and wifi router:  uninstalling and reinstalling g home on my android phone: setting up using remote as well as g home:  using Qr code and code: talking the chromecast to downstairs tv, where original chromecast works fine:  original chromecast still works on downstairs tv: tried original chromecast on upstairs tv and that still works. Any suggestions other than new chromecast isn't working properly?

Hi Fransafe,

Thanks for reaching out. I understand that your Google Nest Chromecast device isn't connecting to the network. I know this can be frustrating, but don't worry, I'm here to help!

Before I can assist you further, I'll need to ask a few questions to better understand the situation:

• What is the model of the phone you're using?
• Was your Google Chromecast device connecting to another account or WiFi network previously?
• Did the inconvenience start during the setup process or after it was completed?

I'll be waiting for your response.

Regards,

Manuel
