Why does WiFi network go down when internet connection is lost?

Hi @Harry_Gosman , 

When the AP disconnected from the Internet, the SSID will not disable. However, if there's a repeater AP in your topology, the repeater AP's SSID will disable when it lost connection with the root AP. 

I did a test to disconnect the Internet from the gateway's WAN port and the APs kept the smart mesh connection and sending SSID. I used the WiFi scan tool (Airport) on my iPhone to check the SSID broadcasting status. May I know what are the steps to reproduce your issue and what's the wireless scan tool you used to check the SSID broadcasting?

The smart mesh is used to extend the wireless signal and failed over let the root AP changes from root to repeater if it cannot reach default gateway. So, may I know what's your topology? Do you use the smart mesh?
