I have set up my Google Nest Wi-Fi Guest Network for a visiting family member. They brought their own personal Google Home Mini with them for alarms and reminders. When I try to set up their Mini on the guest network it says I need to disable AP Isolation on my network. From my research AP Isolation is also called guest network. Can anyone assist in helping me set this up on my Google Nest Wi-Fi Guest Network so they can control their device independently?
You won't be able to set it up on the guest network, as the guest network has the security feature you referred to, known as AP isolation enabled and you can't disable it for the guest network.
AP Isolation is a feature of routers that creates a separate virtual network for each device that is connected to a network. When this feature is enabled, all wireless devices connected to that network will not be able to communicate with each other, in this case the phone or tablet being used for setup cannot communicate with the Google Home Mini.
As we got our resolution here, I'm going to mark this thread as resolved. I'll be locking this thread if we won't hear back from you in 24 hrs. Should that happen, feel free to create a new one if you have more questions or have other concerns in the future.
