Why Chromecast Keeps Disconnecting
Unfortunately, there isn’t a single cause behind all crashes and reboots, so there isn’t a one-answer-fits-all solution. Depending on your specific circumstance, the problem could be related to the device you’re using to do the casting (like your phone or computer), the app that’s triggering the stream, the network on which you’re using the device, or the Chromecast itself.
How Do I Fix a Chromecast That Keeps Crashing?
With so many possible causes, the best way to navigate this guide is to walk through each of these tips one by one, checking after each step to see if you’ve found the solution. One simple way to restart the Chromecast is by removing it from a power source. Disconnect the power cable from the TV or the wall, wherever it’s plugged in. And then reattach it and wait for the Chromecast to fully power back on before verifying if that was the fix. Restarting a computer should be done the proper way: from within the operating system itself. Phones provide a shutdown option after holding down the power button. The app or browser might need an update to addresses a problem communicating with the Chromecast. If that isn’t doable, Google sells the Ethernet Adapter for Chromecast to let you run a physical cord from the router to the Chromecast, eliminating poor Wi-Fi signal issues. An HDMI extender could also be helpful in moving the Chromecast away from behind your TV, making it easier to catch Wi-Fi. Here are some things you can do if this is the problem:
Stop doing other network-heavy activities like streaming from other devices, playing online games, downloading/uploading files, etc.Prioritize the Chromecast from the router’s QoS settings.Upgrade the bandwidth via your ISP.
One way to help stop this is to disable the option in the Home app called Let others control your cast media, from the Recognition & sharing settings. When this is enabled, all Android devices on the network are notified when you’re using the Chromecast, and can control what gets casted to it. Read more about what you can do to keep your Chromecast private. For example, if the Chromecast keeps disconnecting when you’re using YouTube, find the app in your phone’s battery usage settings and enable the Unrestricted or Unmonitored (or whatever your phone calls it) option so the app in question will run in the background without restrictions. How this works is different for every phone, and even varies between operating system versions. Look through the phone settings (not the app settings) for battery usage toggles, and poke around until you find the app that’s having the issue. Doing this requires you to log in to the router as the administrator. Once you’re in, look for the DHCP or IP reservation section. Disabling WMM-PS has proved helpful immediately for some users.
