We’re sorry to hear you’re having trouble setting up your Chromecast. We ask that you first check our Chromecast Router Compatibility page here for your specific router:
https://support.google.com/chromecast/table/3477832.
If your router is not on that list, please try the additional troubleshooting steps below. If you are unfamiliar with your specific router settings or unsure of how to change your settings, please contact your ISP or router manufacturer for assistance.
Please note:
2.4 GHz Network support only: Chromecast only displays 2.4GHz networks as Wi-Fi options in the setup app. 5GHz networks are not compatible with Chromecast and will not be listed. Please double check that your router supports a 2.4 GHz network. If you are using a dual band router, please ensure that you are connecting to the 2.4 GHz network.
Hidden Networks: If the network you want to connect to is hidden (a network that is set not to broadcast its name), you'll need to manually input the network's name and password. This can be done by selecting ‘Other’ in the drop down list of network selection. After selecting ‘Other’, you have the option to manually input your network SSID and password.
MAC Address Filtering: If your router has MAC address filtering enabled, you'll need to add the MAC address of your Chromecast to the list of filtered devices. The MAC address of your Chromecast is listed at the bottom of the Chromecast setup app.
Additionally, Chromecast requires that your Wi-Fi network and router settings are configured to allow devices to communicate with one another. Please check the following configurations on your router. Please note that all routers are different, so each setting may or may not be applicable to your particular router. If you have any questions or need assistance, please contact your ISP or router manufacturer:
AP/Client Isolation: Chromecast cannot communicate with your router if you have AP/Client isolation enabled.
-DISABLE AP Isolation/Client Isolation on your Wi-Fi router.
Virtual Private Networks or Proxy Servers: Chromecast cannot communicate with your router or computer if any Virtual Private Networks or Proxy servers are turned on.
-DISCONNECT or DISABLE any Virtual Private Networks (VPN) or proxy servers, if applicable, on both your router and your computer.
UPnP (Universal Plug and Play) or Multicast: Your router will not be able to ‘discover or see’ your Chromecast on your WiFi network if you have UPnP or Multicast disabled.
-ENABLE UPnP (Universal Plug and Play), also known as Multicast, on your router.
IGMP (Internet Group Management Protocol): Chromecast will not be able to communicate with your router if you have IGMP disabled on your router OR IGMP Proxy enabled on your router.
-ENABLE IGMP on your router.
-DISABLE IGMP Proxy on your router.
Please keep in mind that resetting or making changes to your router settings may have unintended consequences. If you have questions or concerns, please consult your router manufacturer or ISP before making any changes.
