If you have trouble setting up your Chromecast or Google Nest or Home speaker or display, try this:
Disable Access Point (AP) isolation, also known as client isolation or guest mode, on your router- Your Wi-Fi network configuration prevents devices from communicating with your device. To resolve this issue, you'll need to disable AP or client isolation on your router. Refer to your router documentation to learn how to disable AP isolation.
- If you don't have access to your router settings, or if you attempt to connect through a guest, hotel or public network with AP or client isolation, you won't be able to set up your device.
- If you attempt to connect through a Wi-Fi extender, check your extender settings. You'll need to disable AP isolation on your Wi-Fi extender before you set up your Chromecast or speaker or display, to work with your Wi-Fi network.
