C hen your Chromecast does not work, the first thing to try is to reboot the device. The easiest way to do this is to unplug it, wait a few minutes, and then plug it back in.
Wait a few minutes for it to start, and then try casting to your device again. Most of the time, this will solve the problem, but if your Chromecast still isn't working, proceed to the next step.
Check your Wi-Fi
Often times when your cell phone or other Wi-Fi connected devices are down, it comes down to the router. The fact that it is working on a device does not rule out that your Chromecast does not work.
A quick power cycle of your router should eliminate any potential problems. Just unplug your router for a few minutes and then plug it back in. Once your router has started , try connecting again.
Another possible cause of poor connectivity is the location of the Chromecast behind your TV. Yes, the device is very well hidden, but it may not receive enough Wi-Fi power to stream your favorite shows.
If your Wi-Fi is fine and you're still having trouble, try connecting the HDMI extender included in the box and moving the Chromecast away from your TV.
If you have a Chromecast Ultra, you have the additional option of connecting an Ethernet cable to the power source.
Restart your computer or mobile.
As always, many problems are solved with a quick reboot. Whether you're streaming from your mobile, tablet, or computer, a quick reboot may be the best solution.
If your Chromecast is still not working after a fresh restart, proceed to the next solution.
Update your Chrome browser.
If you normally send content from your computer, there may be a newer version of Chrome available. This can cause your Chromecast to stop working or prevent the cast button from appearing on various websites. Follow the steps below to verify.
- Open Chrome on your computer.
- Click the More icon in the top right, yes, the one with the three dots.
- Click Update Google Chrome.
