Chromecast is a device that works as an alternative to turning the TV into a smartphone but, like other electronics, is subject to failure. It is not that rare for the device to crash on certain occasions, such as when playing YouTube videos or when mirroring the PC image. In times of failure, the device may become disconnected or lose image quality, for example.
Check out eight tips on how to solve the most common Chromecast video connection, imaging, and playback issues on your TV.
Simple problems of momentary connection can be solved with a simple reset on Chromecast. Locate the device’s physical button and hold for a few seconds. The TV screen will erase moments later. Chromecast will restart and attempt to re-establish the connection. If the fault persists, go to the next step.
Check the Wi-Fi signal
Errors in the Wi-Fi network are among the most common causes of Chromecast failure. Check that the network signal bar on the TV screen is too weak. If so, you must take steps to get the device closer to the router.
If possible, change the position of the devices in the house so that they have direct access through the air, without barriers created by the TV or other appliances. Depending on the layout of your living room, the television can block the incoming internet signal on your Chromecast.
Use an HDMI cable with an extender
Chromecast comes with a small extender (removable on Chromecast 1 and fixed on Chromecast 2), but you can purchase a longer cable to leave the device even further away from the TV and near the router. HDMI extenders can be purchased at electronics stores. To use, simply plug one side into Chromecast and another into your TV’s HDMI port, moving your device away from Google to the broadband source of your home.
Check your Wi-Fi network performance
If the signal received by your Chromecast is high, you need to check the stability of the connection. As a first attempt, restart the router. Then, if the problem is not resolved, disconnect other devices from the network, such as mobile phones and computers.
Also, make sure anyone in the same house is downloading heavy files or streaming video or high-resolution games. Depending on your router model, these activities can overload your network and interfere with the operation of your Chromecast.
Discover the best channel and change the router frequency
Chromecast 2 supports dual-band Wi-Fi, compatible with channels in the 5 GHz frequency band, which is less congested. First, find out the best connection channel on your Wi-Fi network and then access the router settings to change the default frequency. The next step is to restart Chromecast to test the new channel and verify that the device has actually stopped braking.
Use an Ethernet cable
Unstable Wi-Fi networks can be bypassed using the wired connection on your Chromecast. The Chromecast Ultra, which is compatible with 4K videos, already comes with Ethernet to cable. In addition, it is possible to purchase an adapter to connect to the conventional model and use the RJ45 plug to bring a more stable connection to your streaming.
Connect your Chromecast directly to the wall outlet.
Failures in power supply can also influence Chromecast performance. If you use the device connected to the TV’s own USB port, try using the original adapter that came with your Chromecast to connect the device directly to the power outlet. Problems with TV USB may occur more commonly on old or unknown devices, which tend to present conflicting specifications on the power port.
Decrease screen resolution and videos on PC
If your Chromecast is crashing when mirroring or streaming videos from your PC to your TV, you can change the resolution for best results. In the case of mirroring, Google no longer controls the quality of streaming through the browser, so the user has to manually change the display setting of the computer to send fewer data via Wi-Fi and achieve better performance.
When streaming videos through services like Videostream, the recommendation is to use a converter to decrease the size of the files to be transmitted from the computer to the TV. In general, files larger than 1 GB tend to consume the Chromecast buffer quickly and freeze the image. Therefore, the idea is to keep videos below the 1GB mark.
