Chromecast not connecting to WiFi

[KenSwe]

Everything was working fine until yesterday when we upgraded our broadband with a new router and password. Tried to connect the chromecast to the new network but no joy. Google home app is finding the Chromecast, locating the new network, but when I sign in with the new details, it fails to connect. Now I can't use any apps like Netflix etc. I've factory reset the chromecast, reinstalled the Home app and reset router and restarted both the phone and TV.

TV is LG, phone is Motorola Móto G84 and Chromecast is 2nd gen. Network is around 300-500 mps on WiFi. Any help would be appreciated as family is in mini meltdown.

I have the same issue... Can you have any help for this problema?

The same issue happened to me starting yesterday as well, but there was no change in the wifi network that led to this, it's just that when I turned on the TV to show some videos on it using the Chromecast as my daily habit, I was surprised by a message on the screen that it cannot connect to the wifi network and when I did all my attempts including a factory reset, restarting the router and restarting the TV as you did, I got nothing and I live in Egypt by the way and I didn't know if the issue is general or specific to me until I saw your message, it seems that something has happened either on the device support side or on the internet and router side and I don't know what the solution is so I hope someone can help us to find a solution!

I don't know what happened, but by checking some of the router settings, I found a setting related to mac filtering that I had previously done and added this same Chromecast but in the whitelist so that only it and the rest of the list can be connected, but I was surprised that the list turned from a whitelist to a black list, so the opposite became the case by preventing all devices in the list from connecting ... When I disabled the mac filtering function, everything worked as before .... I don't know what caused this change, maybe there was an update that changed the mac address of Chromecast or something like that, I don't know, but the issue has been resolved, so please ask the questioner to check all these settings, maybe the same situation happened to you!

Hello KenSwe, 

Thank you so much for posting in this community. I’m sorry to know that your Google Chromecast 2nd Gen is not connecting to your WiFi network. Don’t worry. It’s a pleasure to assist you. 

I’m grateful for your time and effort in completing these troubleshooting steps described in the post. So let's explore more tips.

The Chromecast device 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. Proximity allows for the best Wi-Fi connection possible.

Try to set up a mobile hotspot on a second mobile device.

• On the second device, turn on mobile data and hotspot.
• On the first device, turn on the WiFi, then connect to the hotspot of the second mobile device.
• From the first device, open the Google Home app.
• Choose the Chromecast that you want to set up.
• Follow the prompts until it reaches the Wi-Fi setup screen.
• Select the mobile hotspot as the WiFi network.
• Enter the password for the hotspot network.
• Click the Set Network button.

Additional information: You can try to follow these steps:

• Disconnect your wifi network.
• Try to perform a factory reset again. When your device is ready to set up again, reconnect the wifi network.
• After that, open the Google Home app and start the setup process.

Keep me in the loop, and I can provide additional information.

Best regards,

Daniel
