Depending on the cause, different methods may be used to fix the Chromecast keeps disconnecting issue. If the router is the problem, repositioning the Chromecast device, extending the range, or power cycling the router can help resolve the issue. 

Other solutions that can help include updating the Chrome browser, power cycling the Chromecast device, and factory resetting the Chromecast device. Chromecast connection issues will cause the video you are watching to pause from time to time or even fail to load altogether. 

Get to know the common causes of this issue and how you can troubleshoot the problem. Throughout this guide, you will also learn the various methods and steps you can use to resolve the Chromecast keeps disconnecting problem. 

What Causes the Chromecast to Keep Disconnecting from Wi-Fi? 

The Chromebook device is a relatively affordable device that may be used to stream phone or computer content to a TV. To achieve this, the Chromebook needs to be set up and functioning as it should. Different issues have been reported to plague this device since its introduction into the market, with connection issues being some of the commonest. 

Regardless of the model you are using, here are some of the things that can cause your Chromecast to regulate disconnect from your home Wi-Fi network: 


Wi-Fi networks have a range, within which they are usable. If this range is extended, the device will automatically disconnect. Again the connection weakens with an increase in distance from the router, resulting in shoddy stream quality. 

Chromecast devices later than the first generation support both 4GHz and 5GHz Wi-Fi network frequencies. While the 5GHz Wi-Fi frequency allows for a faster connection, it supports a shorter range. In either case, moving the Chromecast device closer to the Wi-Fi router will strengthen the connection and eliminate other connection issues.

Other Router-related Issues

You can also experience Chromecast connection issues when your home Wi-Fi network is overloaded. In other cases, the problem could be a wireless interference or channel overlap with nearby devices or hotspots and routers. 

Outdated router drivers can also cause the Chromecast device to disconnect irregularly. 

Outdated Browser

If you are casting videos from the Chrome browser to your TV through the Chromecast device, check to see whether you are using the latest browser version. Outdated or corrupted browser files can cause connection issues as well. 

How to Fix the Chromecast Keeps Disconnecting Issue 

In most cases, the device remains connected to the Wi-Fi network for 5 minutes or so before disconnecting automatically and reconnecting yet again. Just as there are different causes, different solutions may be used to fix the Chromecast keeps disconnecting problem. 

Discussed below are some of the most effective methods and steps you can use to address this problem: 

Method 1: Power Cycle the Chromecast Device and Router

If your Chromecast device keeps disconnecting, you should first reboot it, or better still power cycle it. To do this, you need to shut the Chromecast device down, and then unplug its power cord. Allow it to sit unplugged for about 5 minutes and then plug it back in. 

Power the device back on and allow It enough time to boot up. Once powered up, check to see whether the connection issue had been resolved. If not, try power cycling the router/modem as well. 

How to Power Cycle a Wi-Fi Router 

If the problem is on the router side, power cycling the device may fix it. To power cycle, your router, power it off and then unplug the power cable from the output socket. Let it remain unplugged for about 30 seconds, and then plug it back in. 

Power the router back on and wait for it to boot up. Once ready, try reconnecting the Chromecast device to see whether the problem has been fixed. 

Method 2: Check the Range 

The TV, Chromecast device, and Wi-Fi router are not meant to be too far apart. Placing them too far from the router can lead to connectivity problems. Positioning the Chromecast device closer to the router allows for a stronger and more reliable connection. 

For optimal speeds, the Chromecast device should not be placed more than 30 feet from the router. If placed more than 50 feet away, the signal will be poor and may even disconnect randomly. 

Method 3: Update your Chrome Browser

If you are casting from the Chrome browser on your laptop or phone, ensure that you are using the latest version of the browser. If the Cast button is not appearing on the various streaming websites, your browser is probably outdated or corrupted. 

If this happens to be the problem, updating the browser will fix it. To update the Chrome browser, you first need to launch it on your computer. Next, click on the three-dot Menu icon towards the top-right corner of the window. 

If the ‘Update Google Chrome’ button appears, click on it and follow the on-screen prompts to update the browser. If the ‘Update Google Chrome’ does not appear, it means that you are already running the latest version of the browser. Finally, click on the Relaunch button.

Method 4: Refresh the Media Router on Your Browser

Before attempting the more advanced solutions, you should consider refreshing the media router as well. To do this, launch the Chrome browser on your PC  and then open a new tab on the browser. Now type chrome://flags/#load-media-router-component- into the address bar of the new browser tab.

Press the Enter key on your keyboard to load the ‘Extensions and features’ screen. Check the status for the ‘Load Media Router Component Extension’. If it is disabled, you need to change it to Enabled. If it is already Enabled, toggle it to Disabled, Relaunch the browser, and repeat the above-described procedure to Enable it again.  

Once you are done, try casting videos from your Chrome browser to the Chromecast device. 

Method 5: Factory-Reset the Chromecast Device 

The Chromecast keeps disconnecting problem may also be caused by faulty settings on the Chromecast device. In such a case, resetting the device to its factory settings should fix the problem. The various Chromecast versions—including the second and third-generation Chromecast as well as the 4K-enabled Chromecast Ultra—feature a physical factory reset button

In most cases, the reset button on these devices is positioned close to the power port. Regardless of the Chromecast version, you are using, here is the procedure you should use to factory reset the device: 

Step 1: Plug the Chromecast device into a power source, using the power supply and USB cable that comes with the device.

Step 2: Now press and hold the factory reset button on your device for about 25 seconds. During this period, the LED lights on the device should blink orange. When the device is done resetting, the LED light will turn white. You can release the reset button at this point. 

Step 3: Pair the Chromecast to your TV, whereby you will be required to set it up afresh. In this regard, you need to set it up the way you did the very first time you used it. Once ready, you can connect to your Wi-Fi network and try streaming to the Chromecast to see if the problem has been fixed. 

Method 6: Check the Power Supply 

The Chromecast device may malfunction if connected to the wrong power supply. You should only use the power supply that came with the Chromecast device. While most TVs are fitted with a USB port, they may not supply enough current to power the Chromecast device. 

You may find it more convenient to just plug the Chromecast into a USB port on your TV set, but this is not advisable. If the current is not enough, the Chromecast will shut down unexpectedly. Again, such a setup means that the device will shut down every time the TV is turned off. 

As such, it may constantly reboot the next time the TV is powered on. To avoid this, the manufacturer recommends using the USB cable and power supply unit that came with your Chromecast device. You can plug the power supply into a nearby outlet socket or a power bar. 

Method 7: Reconfigure Your Network Preferences

You can also fix different other connection issues by giving the Chromecast top priority within your home Wi-Fi network. This can be calibrated from the Quality of Service (QoS) settings on your Wi-Fi router. This solution is particularly beneficial to people with numerous devices connected to the Wi-Fi network. 

By default, routers are meant to treat all devices equally. As such, your Chromecast device may get disconnected when too many devices connect to the Wi-Fi network. Prioritizing the Chromecast on your router ensures that it is never disconnected. The procedure may differ from one router model to another. Basically, you need to log into the router settings page. 

This is done by entering the manufacturer’s default IP address into your browser. (The address will look something like You should then log into the admin settings—using the default username and password in most cases—where you can reconfigure the priority settings.

Method 8: Turn Off Battery Optimization for Your Streaming Apps 

When activated, the battery-saving feature on many devices automatically regulates battery usage by all the installed apps. If any of the installed apps happens to be running in the background, it will be automatically shut down if its battery usage is more than the limit. 

This essentially means that most streaming apps cannot run in the background with the power-saving mode activated. Even if the apps are not killed in the background, their connection with Chromecast will be cut off. If you are casting such apps as Hulu, Netflix, or YouTube on Chromecast, you may encounter connection issues just because the power-saving mode is on. 

If this happens to be the problem, in your case, disabling the power-saving feature or exempting your streaming apps can help fix the problem. This solution can also be used to fix the disappearing Chromecast controls issue. Here is the procedure you need to follow, in this regard:

Step 1: If you are using a smartphone, you need to navigate to the Home screen. You should then swipe down from the top of the screen to pull the Notification shade down. Now click on the cogwheel settings Icon. Alternatively, you could just launch the Settings app on your phone. 

Step 2: Tap on the search bar at the top of the Settings menu and type in Battery Optimization

Step 3: Tap on the first option on the search results displayed to open the Special App Access Settings menu. You need to select the ‘Battery Optimization’ option on this menu. By default, this will display a list of the apps installed on your phone that are not optimized. 

Step 4: Tap the Highlighted ‘Not Optimized’ option at the top and then select ‘All apps’ from the drop-down menu. 

Step 5: Scroll down the list of Apps and select your streaming app. Tap the ‘Don’t optimize’ button to exclude the app from the battery optimization settings. Finally, you need to tap Done to confirm this change. 

Final Verdict 

Different things can cause your Chromecast device to keep disconnecting. The problem could be on your router, phon, or even the Chromecast device itself. Having ensured that dthe evice is within range, you can update the Chrome browser, reconfigure network preferences, or refresh the media router to fix the problem. Depending on the cause, disabling the battery optimization feature on your casting phone or computer can also resolve the problem.
