How to Connect a Chromecast to WiFi

1 Credentials

In order to connect to a wireless network, you must have the required credentials. These are:
  • Wireless Network Name (SSID)
  • Wireless Network Key (Password)

Finding Network Credentials

Most wireless routers or gateways have a label with the default credentials. If the credentials aren't there, check the documentation that came with your device.

    Welcome screen with Get Started highlighted.

  2. Choose which Google account you want to connect to the Chromecast.
    Choose account screen.

  3. Google Home requires permissions to see your location in order to find nearby devices. Click Next.

To help troubleshoot the problem we should check if other devices can connect to the wireless network.

If other wireless devices are connected to the network and functioning properly, chances are the router is OK. It's possible there is an environmental issue. Do you have a portable wireless device (Smart Phone, Tablet, Laptop, etc.) that you can put in the same area to test and see if that device's wireless connection still functions as intended in that location?

If you haven't already, please try power cycling the device you're working with.

  1. Turn off your device.
    Power
  2. Wait ten seconds.
    Wait 10 seconds
  3. Turn your device on again.
    Power

Although Chromecast is compatible with most networking equipment, some routers or gateways may cause issues when trying to connect your Chromecast to them. Usually when networking equipment does not work with Chromecast, it's because it lacks support for the network protocols that Chromecast uses to operate.

The table below covers networking equipment that has been found to cause issues for Chromecast users. Be aware that the majority of this list is made up of older networking equipment, but may still exist as part of a home network.

We try to keep this list up-to-date, but it is only indicative. If your router is on this list, you may need to contact the manufacturer for further details or replace your router or gateway with a more recent product.

Some wireless routers broadcast a dual-band wireless signal and provide both 2.4GHz and 5GHz wireless networks. Your device may not see the 5GHz network, which is completely normal. Not all devices contain the antenna to communicate on the 5GHz band. Also, some routers broadcast guest networks that your device may not be able to connect to depending on your router's settings.

The device needs to be within a reasonable range of the router in order to connect and have the best connection speeds.

  • In general, in most homes, you can be up to 30 feet from your router for a decent connection.
  • From 30' to 50' away, the speeds will be slower, and may drop occasionally, but it should be usable.
  • Greater than 50' away, and the signal will most likely be too weak to overcome interference. The speeds will be slow, and the connection may be sporadic.

The above numbers are approximates only. Optimal range may vary based on router make and model.

Your router may need to be relocated to a more centralized location in order to provide better coverage for all your devices.

Bad Placement

Since this appears to be a range issue that can be resolved by putting the router in closer proximity to the device's intended use area, we recommend moving the router to a more centralized location.
If the wireless signal is not reaching the device and moving the router or device in closer proximity is not possible or doesn't resolve the issue, the best option for wireless connectivity is to get a range extender.
