Chromecast won't stay connected to WiFi

[JoeRow]

I recently got a new router and after setting it up, my Chromcast won't stay connected to it. 

It says it is connected, but within a few seconds, it disconnects. Watching it from the WiFi settings it just continously goes through a loop of automatically connecting, and then disconnecting, then connecting, then disconnecting....

I've tried resetting the router, changing the bandwith and channels on it. But nothing seems to work. 

All my other devices (phone, laptop, PC and games consoles) can connect to the router and have a strong connection without any issues. I live in a small 1 bedroom apartment, so the distance from the router shouldn't be an issue. 

My Chromecast was working fine before my new router.

It's ipv6 breaking changes. Disabling ipv6 in the router finally fixed it. Was able to drill down and isolate the bug in my new android phone.

Hi @JoeRow,

Thanks for posting here in the community. I'm sorry to hear your Chromecast won't stay connected to WI-FI. Help's here!

Please try the steps here:

• Factory Reset: This action clears your data and can't be undone. Follow these steps to Factory Reset your Chromecast, depending on the model you have.

Let me know how it goes.

Hello! I am experiencing the very same issue with a new router after a move. I have exhausted all my options. I have factory reset a lot and even had a Google specialist via Chat help me reconnect last time. Now it still having connecting issues after that. Not sure what my next steps should be.

Hi @alecjorden,

Thanks for posting here in the community. I'm sorry to hear that your Chromecast keeps dropping its Wi-Fi connection. Help's here!

To better understand the situation, I'd like to ask a few questions:

• Which Chromecast device do you have?
• What is the status LED light on your Chromecast?
• How far is the Chromecast from the Wi-Fi router?
• Did you get an error message?

Keep me posted.

Best regards, 

Melany

Chromecast 3rd Generation. The light is yellow. My wi-fi is behind the wall of my device. I do not get an error message. All it says is offline on the Home app and everytime I would click the cast option from a video it would never connect. Now it isn’t even displaying google images on my screen.

[gmelanymelissa]

Hi there! 

Thanks for the follow-up information.

To better assist you, I'd like to ask a question:

• Could you tell me how you performed the Factory Reset on your Chromecast?

Keep me posted.

Best regards, 

Melany 

[alecjorden]

Melany,

I followed the instructions for a factory reset. Held the button on the device until light turned white. Tried this several times with no success. Sorry for the delay. Thank you.

Hi @alecjorden,

Thanks for following up! I'm sorry to hear that your Chromecast keeps disconnecting from the Wi-Fi network. I'm here to help.

I appreciate your efforts to troubleshoot the situation. To gather more information, I’d like to ask the following:

• Have you made any changes to your WiFi network?
• Has the Chromecast been connected to this network before?
• What is the model of your mobile device (Android or iPhone)?

Since you mentioned that your Chromecast 3rd generation had a yellow light and changed to white after a factory reset, it indicates that the device is resetting its data. To confirm, did you remove the Chromecast and set it up again through the Google Home app after seeing the white light? If not, you can try one more time performing a factory reset, remove the device from the Google Home app, and set it up again. 

In addition, I’d recommend the following:

• Make sure you have the latest versions of the Google Home app and your mobile software.
• If possible, try adding the Chromecast using a different mobile device.
• Update your router's firmware if needed. Outdated firmware can sometimes cause issues.

Please keep me updated.

Best regards.

Hi Jennifer,

I never had issues until I recently moved. It is a new wi-fi and router and was recently updated. As for my phone it is an iPhone 13 pro.

When reseting I have tried removing the app and redownloading a couple times. Reseting the router. Basically all of the basics have been attempted multiple times. It will connect while I have the TV on but the next day or later won’t work. Do I just need a new Chromecast all together? I will try as you suggested and report back.

Hi @gmelanymelissa, 

Apologies for the delay, I submitted the form as soon as you posted this message. Has there been any update? We are still using our old (slower) router so that we can use our Chromecast with Google TV. If I try switching to the new router the problem starts again.

Many thanks,

Hi @gmelanymelissa ,

I am also experiencing a connection issue like this.

Previously, all my devices were connected without issue. My router was recently upgraded to the Zyxel EX3301-T0 and I have been unable to get one of my Chromecasts to connect. The model of the chromecast that can't connect is the Gen 4 Chromecast with Google TV. I also have a Gen 3 Chromecast that has connected without issue.

I have followed all the steps mentioned above, there are no error messages and the LED light slowly pulse white while it is trying to connect.

this is a video showing the device trying to establish a connection

Any help you can provide to resolve this is really appreciated. 🙏

[garnerama]

Hi @gmelanymelissa,

I seem to have had the same problem as @Nemcy and similar to @alecjorden . My Chromecast with Google TV keeps dropping WiFi and reconnecting every few seconds, just as in the video posted in @Nemcy 's comment, also HyperOptic network too. This has only started happening after we got a new router that would allow faster download and upload speeds, same network otherwise.  I tried factory resetting both the chromecast and the new router and the issue still persists, both are on the latest firmware. It seems like it could be a compatability issue between the router and chromecast. Every other connection transferred over to the new router without a problem. Changing back to the old router fixes the Chromecast connection issues, but this is not the sustainable fix since this the speeds we can get on the rest of the devices. Any advice would be greatly appreciated!

Many thanks.

Same issue, hyperoptic hub and Chromecast with Google TV, Chromecast keeps disconnecting from WiFi. I've tried connecting only to the 2.4ghz band and 5ghz but the issue persists. Formatting device does not alleviate issue. Any help would be appreciated!

[BigBlue]

Just tossing this in here.  I've got 2 of these devices and they both have been doing it.  Sometimes it's worse than others.  It's really ridiculous.  Google makes some of the worst hardware.  They won't acknowledge or address this.

[Neuquen]

I have the same Problem as the ppl above.

I factory-Reset google TV and it still looses conection instantly.

After a router-restart its works. Until the next day, I turn the TV on and it looses the conection again instantliy. Router-Restart and it works again...

Hello, I am having the exact same issue. My Chromecast worked fine with the same router for months, then it suddenly started going through this connection-loop and is not usable anymore. I am not aware of any change in between, I did not change any router or Chromecast settings.

[Snaht]

The new update DDOS'd my entire network service. You'll be hearing from my ISP. This is totally not acceptable.

[dmichailidis]

Hi,

I am also experiencing the exact same issue with the users above. I have a new router and my chromecast connection keeps going on and off. I have temporarily connected my old router and the connection is stable. 

Can we get an update on why this is the case? It seems to be a recent behaviour.

Thanks

[moralesvicente]

Any Chromecast TV in Canada is having an issue hey. Probably due to your new streaming device, that's region locked to the United States.

[dmichailidis]

Hi, 

Thanks for the reply.

1. My device is Google Chromecast (2020) with Google TV (4K).

2. The firmware is 3.72.425634.

3. The behaviour is related to a change in the WiFi network (new router).

Thanks

[tcabral]

Same thing here, chromecast stopped connecting. Tried resetting to factory defaults but now just stuck in set up where it tries to connect to a wifi. I have two networks at the house and both will connect for a second or two, get an assigned IP and then drop.

[tcabral · Accepted solution]

It's ipv6 breaking changes. Disabling ipv6 in the router finally fixed it. Was able to drill down and isolate the bug in my new android phone. 

[EMK]

Has anyone found a fix for this issue? Started Hyperoptic on Thursday and have the same connection/disconnection loop that everyone else is experiencing.

[tcabral]

Disable ipv6 in your router

[jfran]

Had the similar issue and gave up and never really bothered to follow up as i was able to use my nowtv box instead of google tv, however followed the solution offered above disabling IPv6 on the zyxel ex3301 router and it solved the problem.

To disable the IPv6 settings, you would need to access router settings (192.......) and in network settings-> home networking -> LAN settings -> LAN IPv6 active change to no, apply changes, restart router and viola... Hope that helps

Hello. I am having the same issue with my Chromecast. 

[virnab]

Hi  Gabrielch,
 

Thanks for posting in the community.

I’m sorry to hear you’re experiencing the same issue as JoeRow Please try the troubleshooting steps provided by our Community specialists: gmelanymelissa, jenniffert, chaconmorales, ovidioj, and moralesvicente have already provided.  Additionally, tcabral shared a potential solution.

Beyond these steps, you might also consider the following:

Please verify the bandwidth connected to your Chromecast device. If your router supports both 2.4 GHz and 5 GHz, ensure your Chromecast devices are connected to the 5 GHz network. Here's how to check the bandwidth:

1. At the top right of your TV screen Select your account icon.
2. Select: All settings, 
3. then select Network & Internet.

If the previous requirements are met and you can’t connect your Chromecast to your WiFi Network, please try these troubleshooting steps:

• Update your router's firmware: Outdated firmware can sometimes cause issues. Make sure your router is running the latest software.
• Restart your streaming device: Unplug the power cable, wait 3 seconds, then plug it back in.
• Restart your modem or router. Refer to your manufacturer's instructions.
• Reduce Wi-Fi or Bluetooth interference: Move your router within 20 feet of your Chromecast devices and keep it away from other devices, wires, or cables.
• Check your wireless network's capacity: Ensure it can handle the number of connected devices.
• Improve wireless coverage: Consider using a mesh network like Google Nest Wifi.

Please let me know if these suggestions are helpful.

Best regards,

Virna

Has this change to your router affected any other WiFi connected devices in your network?

[jfran]

Hi, I have had no other issues since disabling IPv6
