Chromecast won’t connect to the Wi-Fi. So I factory reset it and now it won’t authenticate(?)

[Fhon15]

Pretty much the title. I got a new router but everything else stayed the same. I’ve tried the 5 Common Troubleshooting Steps but I still cannot connect to the Wi-Fi. I either get a “Check internet connection” screen on my TV or a “The Chromecast needs to be authenticated” type message on my Samsung Galaxy. I never had these issues with my old router and all my other devices are connecting to the Wi-Fi perfectly well. Please advise.

Hi everyone,

I want to share my fix, it may help you to resolve the wifi issue. Well, I am using Chromecast with my Samsung tv smart hub. after many attempts today I disabled all network settings from my TV like CEC-HDMI and wifi of my tv afterward I connected my chrome to my tv and started setup and luckily I got success. Now my device is set up and ready you can try it.

Hey folks,

Thanks for sharing your resolution in the Community, ImranDanish1 — we appreciate it!

Fhon15, have you tried the suggested steps shared by ImranDanish1? If yes, how was it? If you're still having trouble, please reboot your Wi-Fi router, Chromecast, and mobile phone. Reinstalling the Google Home app and using a different mobile phone might also help.

Regards,

Jennifer
