We will delve into the fundamental reasons that your Chromecast loses its connection from time to time, as well as the potential ways how to Fix ‘Chromecast Keeps Disconnecting’ issue. There is more than one possible explanation for why your Chromecast loses its connection.
Causes of the ‘Chromecast Keeps Disconnecting’ issue
- Router Configuration: Incompatible router settings, such as conflicting channels or firewall restrictions, may disrupt Chromecast connectivity.
- Interference: Other electronic devices or appliances operating on the same frequency can interfere with the Chromecast signal.
- Overheating: Excessive heat buildup in the Chromecast device or the TV’s USB port can cause intermittent disconnections.
- Software Glitches: Firmware bugs or outdated software on the Chromecast or casting device may trigger connectivity issues.
- Power Supply: Insufficient power supply to the Chromecast device, especially when powered through the TV’s USB port, can result in unstable operation.
- Physical Obstructions: Physical obstacles between the Chromecast and the router, such as walls or furniture, can weaken the Wi-Fi signal and lead to disconnects.
- Device Compatibility: Compatibility issues between the Chromecast and the casting device (such as smartphone, tablet, or computer) can cause connectivity problems.
How to Fix ‘Chromecast Keeps Disconnecting’ issue

Check Wi-Fi Signal Strength
- Primary reasons for Chromecast disconnecting: poor Wi-Fi signal strength.
- Ensure Wi-Fi router is placed in a central location, unobstructed by walls or other objects.
- Use a Wi-Fi analyzer app to identify interference, switch to a less congested channel if necessary.
- Signal strength crucial for stable Chromecast connectivity.
Power Cycle Your Chromecast
- Sometimes, a simple power cycle can resolve connectivity issues.
- Unplug your Chromecast from the power source, wait for a few seconds, and then plug it back in.
- This reboot process can often rectify temporary glitches causing the disconnecting problem.
Verify Power Supply
- Ensure that your Chromecast is receiving an adequate power supply.
- Use the provided power adapter and avoid connecting it to USB ports on your TV, as they may not provide sufficient power.
- Power supply instability can lead to intermittent disconnections.
Update Chromecast Firmware
- Check for any available firmware updates for your Chromecast device.
- Outdated firmware can cause compatibility issues and connectivity problems.
- Go to the Google Home app on your smartphone or tablet,
- Navigate to your Chromecast device settings, and check for updates.
- Firmware updates often include bug fixes that can address connectivity issues.
Reset Chromecast
- If none of the above steps resolve the problem, consider resetting your Chromecast to its factory settings.
- This will erase all settings and data on the device, so proceed with caution.
- To reset your Chromecast, press and hold the reset button on the device for at least 25 seconds until the LED light begins flashing.
- Follow the on-screen instructions in the Google Home app to set up your Chromecast again.
- Factory reset can eliminate any persistent software issues causing the disconnecting problem.
Check Router Settings
- Review your router settings to ensure that they are optimized for Chromecast usage.
- Enable UPnP (Universal Plug and Play) and ensure that multicast is enabled.
- Additionally, consider assigning a static IP address to your Chromecast to prevent IP conflicts that may cause disconnections.
Reduce Network Congestion
- Limit the number of devices connected to your Wi-Fi network, especially during streaming sessions.
- Bandwidth-intensive activities such as torrent downloads or online gaming can saturate your network and cause Chromecast to disconnect.
- Prioritize streaming traffic by using Quality of Service (QoS) settings on your router.
Conclusion
The problem could be related to the device that you are using to do the casting (such as your phone or computer), the application that is triggering the stream, the network on which you are using the device, or the Chromecast itself. This is something that will depend on the specific circumstances that you are experiencing regarding the issue.
When a Chromecast randomly disconnects, restarts, or crashes, it can be difficult to diagnose the problem if you are unsure of what is causing it to occur. If you follow this guide, you will be able to learn what the possible cause of those symptoms is, as well as walk through the steps necessary to fix it.
Questions and Answers
The Chromecast often becomes disconnected due to an unstable connection, which is the most common cause. According to Google’s recommendations, users should keep their Chromecast about 15–20 feet away from their router (or their smartphones when they are using a mobile hotspot). As the distance between the devices increases, the likelihood of a robust internet connection increases as well.
It is possible for streams to the Chromecast to abruptly stop operating if there is interference or a weak signal strength. In the event that this is not possible, Google offers the Ethernet Adapter for Chromecast, which enables you to connect the Chromecast to the router by means of a physical cable, thereby removing any problems associated with a weak Wi-Fi signal.
If you notice that your Chromecast is abruptly turning off, going black at regular intervals, or restarting itself frequently, the issue is most likely connected to the power supply of the device. Chromecasts are powered by the USB cable that is included in the box containing the device, and many television sets have USB ports that are conveniently located next to the HDMI ports.
