Does not connect to Wi-Fi networks (known or new)

[Rosky]

Problems connecting to WiFi networks (even to already saved Wi-Fi networks that have already been used without problem), stays all the time in: "establishing a connection..."

It’s a worldwide problem unfortunately, that started on Sunday.  The authentication certificate was valid for ten years, which ran out on Sunday, and we’ve been waiting for Google to find the solution ever since.  So frustrating!

just change your phones date to any date before 8th march and you're good to go to finish the setup. casting won't work yet tho.

So I will be able to update the Chromecast 2nd generation by changing the date on my phone but then won't be able to cast from my phone after?

[Rosky]

Thank you so much for the responses. I tried to get it connected to the wifi (it was already set up and connected to that WiFi) and it doesn't connect or change the date on the phone or chromecast. If my partner puts the WiFi zone on their iPhone it connects perfectly.

Hi @Rosky,

Thank you for posting in the community. I'm sorry to hear that you are unable to connect your Chromecast device to your Wi-Fi network. I'd be happy to assist you.

Depending on your device model, please provide the following information to determine the cause:

• Which streaming device do you have? (Please specify the model.)
• What's the firmware version?
• What device is used to complete the setup and what's the OS version (iOS version or Android)?
• What's the TV brand and model?
• Can you find the network name on the set up device?
• What's your Internet Service Provider (ISP) and ISP speed?
• How far is the streaming device from the Wi-Fi router?
• Is the device directly plugged into the HDMI port of the TV?
• Do you have more than one streaming device? If yes, does this inconvenience happen to other streaming devices?
• Were there any recent changes to the network?

Please keep me posted. I'll be waiting for your response.

Regards,

Anders

- chromecast google tv

- STTL.241013.003.12571383

-The device is already configured and was working perfectly (nothing has changed), suddenly it doesn't connect to wifi networks created by Android devices giving errors like: " Invalid Wi-Fi password", "limited connection" etc. (password has been checked, changed, network forgotten, etc. and it doesn't connect). If connected to an Iphone wifi zone it works perfectly (sometime it gives the same errors but sometimes it connects without any problem). It has been reset to factory settings and configured again (it also gave these same problems with all networks for a few days until it suddenly connected to the Iphone network and could be configured.

- TV Samsung UE43TU7125KXXC (It is the same TV as always and nothing has changed).

- If you can find the network on the device.

- The android devices where it fails are Vodafone (5G mobile speed of 100Mbps) and also fails on a Movistar router of 100Mbps. The iPhone on which it sometimes works is from the company Euskaltel also almost 100Mbps.

-The devices are at a distance of about 2 meters approximately.

-Yes, it is connected directly to the HDMI port of the TV.

-Yes, there are more devices connected and they all work correctly, I have tried to create a new network and put only the chromecast and gives the same failures.

-There has been no change or update the TV, chromecast, cell phones that act as router, etc..

Thank you very much, hopefully it can be solved as it is very uncomfortable that it only connects to my partner's iPhone and not always.

Hi @Rosky,

Thank you for the information. With this information, let's troubleshoot your Chromecast with Google TV device by following the steps below:

1. Toggle Wi-Fi off and on from the setup device.
   • Go to settings > Select Wi-Fi.
   • Then, toggle Wi-Fi off and then on.
   • Make sure you reconnect to the same Wi-Fi network that the streaming device os going to be connected to.
2. Restart the router.
   • Disconnect the Wi-Fi router from the socket and leave it unplugged for 5 minutes. Start a 5-minute timer to track the time.

   • Check if the router's LED lights are off when the router is unplugged. Some routers have backup battery packs, so you need to disconnect the battery packs to ensure the router completely turns off.

   • Once all router LED lights are back on and the network name shows on the list of available Wi-Fi networks on your phone or tablet, check if the streaming device can connect to the Wi-Fi network.

3. Set up your Chromecast device on a different device.
4. Perform a factory reset.
   • After having followed all the previous steps, perform a factory reset as indicated in the article 'How to factory reset your Chromecast or Google TV Streamer.'

Please keep me posted. I'll be waiting for your response.

Regards,

Anders

Good morning. It does exactly the same, does not connect directly to the router or any Android mobile WiFi zone, only connects to the WiFi zone of the Iphone. I have looked if there was any update to fix this but nothing. The weird thing is that when I turn on the chromecast appears as connected to the Android WiFi Network but instantly loses the connection.

Good afternoon, I have opened a chat with an agent and they have asked me for the address for a replacement since after trying everything he told me I still had the same problem, I also gave him this address so he could also see everything I did. Thank you very much for everything.
