Connecting the Chromecast to home networks if often an easy task, requiring little troubleshooting. The biggest issue we have found is connecting Chromecasts to restricted networks like those you would encounter in schools or large businesses. For the Chromecast to be able to connect to the network and pair with an internet device, some settings need to be enabled or disabled.

Below are some basic guidelines every wireless network needs to follow in order for Chromecasts to work, as well as a chart that identifies issues and workarounds for specific routers and access points. The information was gathered from the Chromecast support pages and is only being provided as a resource to assist in Chromecast connectivity issues.

General Guidelines for Troubleshooting Network Issues with Chromecasts

Disable Ap/Client Isolation

- You will need to disable AP/Client isolation, also known as client isolation, on your router.

- If you do not have access to your router settings, or if you are attempting to connect through
a guest, hotel or public network with AP/client isolation, you will be unable to set up your Chromecast.

-If you are attempting to connect through a Wi-Fi extender, please check your extender settings.
You will need to disable AP isolation on your Wi-Fi extender before setting up Chromecast to work with
your Wi-Fi network.

Enable UPnP

- UPnP (Universal Plug and Play), also known as multicast, allows for the discovery of UPnP enabled devices
on the same Wi-Fi network.

- UPnP makes Chromecast discoverable by other devices on the same network. You will need to enable UPnP in
your router settings. Please refer to your router manufacturer's documentation to learn how to enable UPnP on your router.
