Chromecast won’t connect to 5G

[jrashidd]

My Chromecast won’t connect to my 5G networks but connects to 2.4Ghz one’s fine. Is there a solution?

"5G" is usually used to denote a cell phone communications standard. "5Ghz" is usually used to denote a WiFi communications frequency. I believe your "5G" should be a "5Ghz". Sorry but I don't have a solution for you except to say that my Chromecast with Google TV (4K) does see and connect to my 5GHz WiFi so it is capable of doing so.

Hey there,
 

Thanks for the help, @bsmorgan.
 

@jrashidd, let’s further look into this. What version of Chromecast device do you have? Are you getting any message when connecting it to the 5 GHz band? 
 

I’ll look forward to your response.

Regards,
Alex

Hello jrashidd,
 

Chromecast with Google TV 4K can operate on 2.4 GHz and 5 GHz. It should be within 20 feet or as close as possible to the mobile device used for setup, and equally close to the Wi-Fi router. Close proximity allows for the best Wi-Fi connection possible.
 

Let’s try to do these steps:
 

1. Toggle Wi-Fi off and on from your phone.
2. Reboot the router. Unplug it from the power outlet for 2 mins > Plug back in.
3. Restart your Chromecast with Google TV 4K. Remove it from the power source for a minute > Plug back in.
4. Force close and reopen the Google Home app.
5. Turn on Local Network Access. Go to your phone’s Settings > Privacy > Local Network > Find the Google Home app > Toggle Local Network Access off and on.
6. Try to set it up again on the  5 GHz network.

Best,
Alex
