Google Chromecast is one of tech lover’s most favorite innovations that lets you send things from one device to another. It is also one of the most affordable products one can buy to easily stream media from YouTube, Netflix, Amazon Prime Video, Hulu, Google Play Store, and other services. Google has successfully launched 3 generations of Chromecast and the latest one is called Chromecast Ultra that allows full support of HD content, faster streaming, and more. Also, all these models have been simple, yet versatile and have gone progressively faster, with stronger Wi-Fi support to better hold a connection. You can enjoy your favorite content on Chromecast as long as it is set up right and functions properly.

In this most recent guide, we’ve rounded up the best solutions available out there to the most commonly occurring issues in Chromecast.


Most of the experience on Chromecast is dependent on the quality of streaming which is dependent on a few basic factors like the overall speed and quality of the internet connection. However, other significant factors that aid in this is the router configuration, Wi- Fi signal strength, or the type of mobile device and even settings.

  • Your router may not be broadcasting on a compatible frequency
  • Chromecast may be unable to detect the Wi-Fi network
  • Your device might is missing on some necessary firmware updates
  • Or, the device isn’t getting enough power


#1 (How to) Restart Chromecast:

The very first step to follow when the Chromecast is unresponsive is to reboot it. It is also the easiest and a tried and tested method of unplugging the Google plug, wait for a minutes and plug it back in. Give it a few minutes, and your Chromecast will be up and running and you should be able to cast again.

#2 Reboot the Smartphone, Computer, or Tablet: If you are controlling your Chromecast from your phone, tablet, or computer, try rebooting the device. A quick reboot may resolve multiple problems.

#3 Power-Cycle the Modem or Router

Poor streaming quality or inconsistent connection ruins the plaid content’s quality.

A quick power cycle of your modem and/or wireless router should fix the issues. Simply unplug the router and leave it for a few minutes, then plug it back in. Once the router gets booted, try connecting again.

  • To sort out the range issue you can bring your Chromecast and router closer together for a stronger and a stable signal.

# 4 Put Your Router’s Signal Setting to 2.4GHz

Your Wi-Fi networks operate at two frequency bands: 2.4GHz and 5GHz. However, 2.4GHz is the superior of the two due to its lower frequency, having a better at penetrating power through solid objects.

Go to your router’s settings and check and select the frequency to 2.4GHz for your Chromecast.

Let the other devices be connected to a 5GHz network. Just make sure to check the option – “Enable guest mode” during the Chromecast setup process.

#5 Update Your Router’s Firmware

When you check your router’s settings, it may show that an update is available. New updates help even out glitches and improve network security from external threats.

#6 Adjust Your Router’s Channel

If the channel your router is automatically set to be the same one used by your neighbors, interference may occur. Most routers allow you to toggle between the wireless channels they run on.

  • Go into your router settings>> Wireless>> Channel and SSID>> Channel Field
  • If it is set to “Auto” – Change it to a numbered one and see if there is any difference. If, not, try changing channels till it’s better.

Alternatively, there are many router channel lookup tools available that can scan for wireless networks in your area and display extensive info about these networks such as network name or SSID, channels used, maximum speed for each channel.

  • Use the least used channel to improve the performance of Chromecast, and improve the speed and reliability of your WiFi in general. Chromecast works well on channels – 1, 6, and 11. 

#7 Give Your Chromecast Top Priority on the Router

If there are a bunch of devices using the Wi-Fi, then by default, your router will treat all the data in the same way whether you are watching Youtube, or downloading a file using BitTorrent, or playing an online game. However, there is a way to this, as your router must have Quality of Service option in settings through which you can prioritize Chromecast over other connections.

  • Open your router manufacturer’s default IP address on a web browser
  • Login as admin (default username and passwords are mostly admin and admin)
  • Find QoS settings >> Click on the Set Up QoS Rule button>> Add Networks you want to Prioritize>> Apply

#8 Check your Wi-Fi Connection

  • Check if you’ve recently changed your router’s password and did not update your Chromecast.
  • Or maybe you added another network connection, to which you forgot to connect Chromecast

Most modern routers have multiple networks at the same time. But there is a possibility that your mobile device and the Chromecast are connected to the same router but different networks. Ensure that the Chromecast and your mobile device are connected to the same network.

Go to your mobile’s Settings option to see what network it’s on

Then check your Chromecast settings – If you see if there’s any difference, and connect both to the same network

Once you’ve confirmed the match, you can try and see if Chromecast works, else try the other steps below.


One of the sure-fire ways to fix several malfunctioning issues with the Chromecast is to give it a good ol’ factory reset. This will delete all the app data and your Chromecast numbers will change.

  • Every generation of Chromecast feature a physical factory reset button that is located around the power port and the steps to reset it are all the same irrespective of what version you have
  • Plug the Chromecast into a power outlet with the included USB cable and power supply
  • Press the factory reset button for 30 seconds
  • The LED light on the Chromecast starts blinking in orange to indicate that it’s resetting. Once you see a solid white light, release the button
  • Now plug the Chromecast into your TV and you will see the set-up screen again
  • Simply follow the setup steps again using the Google Home app

# 10 Try Connecting with an HDMI Extender

You must have gotten a short HDMI extender cable in the box. The purpose of connecting it this way is to give your Chromecast a little more room to easily detect the Wi-Fi besides been being physically separated from the TV through this extender cable. The latest edition, Chromecast Ultra also allows connecting an Ethernet cable to the power port.

ERROR: If Your Chromecast has Been Set Up, But You Can’t See the Cast Icon SOLUTION: Follow step #8 above    
ERROR: Chromecast Blacking Out or Turning Off Error  

SYMPTOMS: This is a typical issue where your Chromecast turns off suddenly, blacks-out repeatedly, or it resets itself frequently. All these issues are related to its power supply.

EXPLANATION: Chromecasts are powered by a USB cable that hooks to the television’s USB port next to the HDMI ports. You might have adopted a cable saving measure by plugging the USB cable into your TV, instead of the wall socket.
But this can cause the Chromecast to stop working due to several reasons. When it’s connected to the TV, every time the TV is turned off, it cuts power to the USB ports, which causes the Chromecast to reboot every time you turn off your TV. Some cheaper TVs may have poorly configured or unstable USB ports.  

Unplug the Chromecast USB cable from your TV and plug it into a wall charger. If you don’t have a wall charger, try an old phone charger or buy any third-party charger
ERROR: While Casting, Either the Video Never Plays, or the Quality Is Too Poor
