How to Fix Chromecast Keeps Disconnecting

Several troubleshooting tricks can be performed to resolve the disconnection issue your Chromecast device is suffering from. So, the solutions we’ve listed below should properly fix the problem at hand. 

FIX 1. Restart your Chromecast device

The first thing we recommend you do is to restart your Chromecast device to allow it to refresh its system memory and reset its current running instance. Performing this simple action should correct any minor issues causing it to keep disconnecting.

Once you’ve restarted your Chromecast device and it has completed its reboot sequence, check and monitor if it can connect to your WiFi network without being disconnected afterward.

There are two ways to restart your Chromecast device: by manually plugging and unplugging it and via the Google Home app. 

For the first option, simply unplug your Chromecast device’s wall adapter from the wall outlet. Keep it uplugged for at least 60 seconds before plugging in back in.

The next option is to use the Google Home app on your smartphone to restart the Chromecast device. Here’s how to do it:

You can reset your network’s WiFi router and modem by performing a soft reset or factory reset. Sometimes, a soft reset is enough to fix minor issues on your WiFi router and modem and restore your internet connection to normal.

Unfortunately, there are cases when a simple soft reset seems to be insufficient and factory resetting your WiFi router and modem is your only option.

You can do the factory reset procedure using the single physical button on these Chromecast devices while they’re plugged into a wall outlet.

Whenever you’re using your Chromecast device, make sure only to use the cables that were included in its box to avoid any issues from occurring during use. If the power cable of your Chromecast is already broken, only replace it with a compatible cable.

You also need to double-check if you’re using the wall adapter that came with your Chromecast device. If possible, avoid the use of third-party accessories on your Chromecast device as there might be compatibility issues.

What to Do If the Suggested Methods Don’t Resolve the Disconnection Issue with Chromecast

If  none of the abovementioned solutions fix the disconnection issue, there are other things you can try to do as well. Below are two extra tips you can try if your Chromecast device still keeps disconnecting from your WiFi network.

Contact Google Support for assistance

Troubleshooting your Chromecast device yourself doesn’t always work out as planned. Instead, rely on Google support to help you address and identify the problem that’s causing your Chromecast device to keep disconnecting.

Please note that Google no longer provides support for generation 1 Chromecast devices. As long as your Chromecast device is generation 2 or higher, you can ask Google support for assistance with your device’s ongoing problems.

Buy a new Chromecast device

Google has already discontinued the production of generation 1, 2, and 3 Chromecast devices because they’re now focusing their attention on the new Chromecast with Google TV models.

While you can still buy the older Chromecast devices in stores such as Amazon, it might be better to move to the newer models. We recommend doing this if you’ve already been using your old Chromecast device for a long time.

Note: Google has stopped support and firmware updates for the generation 1 Chromecast device. It’s only a matter of time until the same happens to the generation 2 and 3 Chromecast devices.

FAQs about Chromecast That Keeps Disconnecting

Can you use Chromecast without a network?

Chromecast can be used without a WiFi internet connection, but it must still be connected to a network. You still need an ethernet cable to a network via a wired connection for Chromecast to be usable.

If you don’t have a WiFi router or modem, you will still need a mobile hotspot or a travel router as an alternative network. Simply put, Chromecast won’t work without the internet. 

How do I reset my Chromecast WiFi?

Open your Google Home app, select your Chromecast device, open device settings, and click the forget button beside the WiFi option. From there, you’ll be prompted to reset your Chromecast device and set it up with a new WiFi network.

Will resetting Chromecast delete all my settings and data?

Settings and data are deleted after you perform a factory reset on your Chromecast device. The outcome of this task is permanent, and there’s no way to restore the deleted settings configuration and data.

Will VPN affect my Chromecast’s connectivity and cause disconnection issues?

Google doesn’t recommend using VPN with Chromecast as it’s unsupported. As such, it’s essential to connect your Chromecast device to a WiFi network that doesn’t use VPN to make sure that you can set it up and use it without any issues.
