Chromecast is a digital media player developed by Google that enables users to control and initiate playback of various content on high-definition televisions using computers and other devices.

Like all other portable media devices, Chromecast can have problems. There may be instances where your computer cannot find your Chromecast device. If this is the case, you can try the solutions described below in order to fix the problem.

SOLVED: Chromecast not showing up on computer

Solution 1: Verify the Wi-Fi signal

The first thing you should check is the Wi-Fi signal. If it’s weak, either move the router nearer or consider changing the location.

Solution 2: Check the power supply

Many users use the USB service port on their television as a very convenient way to provide power but it is not actually the ideal way to power your Chromecast. Not all USB ports are created equal on HDTV sets and it is possible that the port is poorly grounded, or otherwise not provided clean and steady power to your Chromecast. Hence, it is possible that Chromecast is not getting enough power supply. You should consider plugging it into the power supply which came with the Chromecast and power it using the wall current.

Solution 3: Restart your router and your computer

It is always a good idea to reboot your router and Chromecast device by unplugging them from the power source for about 2 minutes. Also, reboot you casting device, meaning your computer.

Solution 4: Change Wi-Fi channel

Chromecast is reportedly known to only work on 2.4 GHz on your wireless router. If your router is set to some other frequency band, the device may not be able to connect. Follow the steps here to check it and try to change your Wi-Fi channel to improve your Wi-Fi signal:

  1. Go to the settings page of your router on a browser
  2. Find and click Wireless catalog (probably it is under Settings catalog)
  3. On the Wireless pane, make sure your network operates at 2.4GHz

Solution 5: Use HDMI extender

There is a short HDMI extender cable, about a couple of inches long, that may come with your Chromecast or can be bought separately. You can use it to plug your Chromecast into your TV HDMI’s port. This enables more breathing room for your Chromecast to detect Wi-Fi networks.

Solution 6: Check if Chromecast is connected to the same network

Another useful suggestion is to make sure that your Chromecast device and other devices are connected to the same network. Hence, check that the network name displayed on the TV is the same one currently selected on your computer.

Solution 7: Factory reset from the Chromecast App

If none of the above solutions do not solve your problem, you can go ahead and perform a factory reset. A factory reset will bring Chromecast back to its default settings:

  1. Open the Chromecast app on your computer – check the Start menu, Applications or the directory where you installed it
  2. Click Settings. If you have multiple Chromecasts on your network, be sure to select the one you want to format
  3. Click on Factory Reset
  4. Click on Reset. The Chromecast will now reset to factory settings, and you will be able to restart the setup process.

Solution 8: Manually reset Chromecast

If you cannot access your Chromecast, you will need to take a more hardware-based approach. Google put a hard reset button on both the first and second generation Chromecasts, so you can perform a factory reset easily. So, while the Chromecast is hooked up to the TV, press the button along the edge of the Chromecast and hold it for approximately 25 seconds:

  1. If it is a first-generation Chromecast, release the button when the indicator light switches from solid to flashing.
  2. The second-generation Chromecast‘s LED indicator will begin flashing orange. You should release the button when the LED turns solid white

Solution 9: Disconnect from VPN/ proxy

Chromecast devices cannot communicate with a computer over these networks. If you need help with this, please check with your service provider for instructions.

Solution 10: Verify if firewall/antivirus are not blocking connections

Please make sure that firewall/antivirus software are up to date and are not blocking the connection to the Chromecast device.

To see if the problem is caused by interference with your security software, you can temporarily turn off your security software and check if the problem is solved. Consult your software documentation for instructions to disable it. If this solves the problem, contact the vendor of your security software and ask them for advice, or install a different security program.

All in all, your computer not being able to find your Chromecast can be very annoying, but we hope that you managed to fix this issue after using one of our solutions described above. If you have other suggestions also, please let us know in the comments section below.
