Cannot Cast from PC Google Chrome to either Samsung smart TV or Chromecast device

[RWaszczuk]

So, the background is that I was previously able to cast from my old PC (Windows 10), using an old Wi-Fi router, to an old LCD TV with a Google Chromecast device attached to its HDMI port. No issues. Everything worked.

Recently I upgraded: new PC (Windows 11), new Wi-Fi router, and new Samsung smart TV. The only device that remained the same was the Google Chromecast device. I attached the Chromecast device to the Samsung smart TV's HDMI port, switched over to the HDMI port from the TV's menu, performed a factory reset on the Chromecast device, and stepped through the setup by creating a new device using the Google Home app on my iPhone.

Result? The setup successfully detected not only the Chromecast device, but the fact that the Samsung smart TV had built-in Chromecast capabilities. Okay, fine, but I still setup the Chromecast device. Then I completed the tutorial, watched a trailer for Stranger Things 2 sent to the TV via the Chromecast device, using the app to control everything. Tutorial successfully completed. No issues.

The problem started when I attempted to Cast from my new PC using Google Chrome. Whenever I click the "cast" icon is states "No devices found". No smart TV, no Chromecast device. I searched online for solutions, even going so far as to uninstall Google Chrome, then reinstall it, as I assumed maybe the Windows migration, from Windows 10 to 11, might have caused an issue. Nope. The problem persists.

Tech Info (from Google Home, for device):

System firmware version: 467165

Cast firmware: 1.56.467165

I'm hopeful I can find a solution, as I'm hoping to entertain guests later this month, and being able to cast from my PC to the TV would help add some variety. Else it's free Samsung TV+ and Roku channels for them...

Hi RWaszczuk,

Thanks for reaching out to the community! I perfectly understand what you are describing. You went from an old configuration that was completely functional to a modern setup including Win 11, a new router, and a Samsung Smart TV. You kept the Chromecast and, yes, the initial setup from your iPhone was a total success. You were able to confirm that everything is online.

The irony is striking. The problem is specific the only thing that doesn't work is casting from Google Chrome on your new PC. The browser simply reports "No devices found." You made the logical move of reinstalling Chrome, assuming a migration failure, but the problem persists. It's frustrating because the network is proven to be working and the Chromecast is active. It is a very specific communication block between your PC and the rest of the network that appeared with this change in hardware and operating system. I'm here to help you!

I'd like to ask you a few questions to confirm some details and provide you with troubleshooting steps:

• What is the make and model of the device you used to cast?
• Is the Google Chrome browser version updated?
• Has there been any changes in your network?
• How far is the device from the router?

In the meantime, I would like to perform some troubleshooting steps that might help:

• Check the antivirus of the computer.
• Verify that your new PC is connected to the same network as your Chromecast.

Please feel free to share any additional details you think might be relevant.

Best regards,
Eduardo

To confirm:

• Are you referring to the Desktop PC or the Google Chromecast? If you are referring to the Google Chromecast it a Gen2 model.
  

  • System firmware version: 467165

  • Cast firmware: 1.56.467165

• Google Chrome version 142.0.7444.163 (Official Build) (64-bit)
• Yes, as I have new hardware across the board. However, the network chain is as follows:
  • Desktop PC (Windows 11) connects via cable to modem
  • Modem (old hardware) connects to wireless router (new hardware)
  • Wireless router connects to Samsung smart TV (confirmed) and Google Chromecast (assumed)
    • Connected Google Home app (iPhone) to Google Chromecast
• ~40 feet away in an adjacent room, same floor (keeping in mind previous weaker router was able to connect to the Chromecast at the same location)

With regards to troubleshooting i should mention  no pop-ups occur when triggering the cast attempt, however, I am using BitDefender. It include a Firewall, which is temporarily disabled and tested. However, once again no devices were found. If you have any specific suggestions, please let me know.

I assume the devices are all on the same network, as there is only one wireless router. However, if there is a way to confirm, let me know.

Hi @RWaszczuk,

Thank you very much for the information about your Chromecast (2nd gen), including how your devices and your cell phone are connected to the same Wi-Fi network. Regarding the experience you have been having, I would like to specifically ask you to share feedback about your Google streaming device.

Best regards,
Eduardo

I would, but you know... I can't get the Chromecast to work right now. Maybe if I could figure out the casting issue?

Hi @RWaszczuk,

Thank you for sharing your comments about your situation. I understand that you can't share the feedback through the Chromecast, so for that reason, I'd like to suggest sending feedback from the Google Home app, where you can include your issue.

Keep me posted.

Best regards,
Eduardo
