Google's Chromecast is a portable streaming device that allows users to cast content from their smartphone or computer directly to their TV, but it can be annoying if it disconnects frequently. Google sells the Chromecast in both HD and 4K versions. The Chromecast with Google TV not only enables users to cast content from their devices, but also give their existing TV a smart TV interface thanks to Google TV integration. As a result, users can access all their favorite apps and streaming platforms right from their TV screen.
Since the Chromecast is a streaming device that runs on Wi-Fi, users might occasionally have trouble with the connection. According to Google, the most common connection errors include a message that says the Chromecast can't find the Wi-Fi network, can't connect to the Wi-Fi network, is having trouble connecting due to a router error, or is connected to the network but can't access the internet. For all these errors, the troubleshooting steps are pretty much the same. The first thing to do is check if the Wi-Fi is working by connecting another device. Users might need to reboot their router if not. If this doesn't work, users might need to reach out to their internet service provider for support.
Fix Your Chromecast Disconnecting From Wi-Fi
More often than not, an unstable connection is what disconnects the Chromecast. Google advises users to keep their Chromecast within 15-20 feet of their router (or smartphones when using mobile hotspot). The closer the devices, the better the chances of a strong internet connection.
If the internet connection isn't the problem, rebooting the Chromecast might be the next best thing to do. To do this, unplug the power cable from the Chromecast for one minute. Plug it back in, and the device will automatically reboot. Alternatively, users can reboot from Google TV if using Chromecast with Google TV. To do this, select the profile on Google TV and open Settings. Choose 'System,' then 'Restart,' and finally, 'Restart' again. If using any other Chromecast model, users can restart using the Google Home app. Open the app, press and hold the Chromecast tile, and tap 'Settings.' Select 'More Settings' and tap 'Reboot.'
Another way to fix Chromecast Wi-Fi issues is by resetting it. Note that this method will result in any saved settings being wiped. To reset the Chromecast with Google TV, make sure that the device is plugged in to the TV and powered on. Press and hold the button on the back. The LED will start blinking yellow. When it turns white, release the button and the Chromecast will be reset. To reset the Chromecast 2nd gen, 3rd gen, or Ultra, follow the same method by pressing the side button, but note that the LED will first turn orange and then white. If using the 1st gen model, press and hold the side button for 25 seconds or until the LED starts flashing red. When the LED turns white and the TV screen goes blank, release the button to reset.
In some cases, using the Chromecast with poor quality third-party cables can cause a disconnection issue. If the original wires are worn out, users might have to get a replacement. If none of the methods work, it's time to contact Google Support. Users might be able to get their device repaired or receive a new one in the warranty period. While Google has ended support for the first-generation Chromecast, it continues to provide technical support for later models of the device.
