Flat network
1) Unifi located at location 1 , and one of connection (rj45) connected to IAP 105 x 2unit (for mesh) .
2) And one connection from unifi router to location 2 (rj45) connected to IAP 105 x 1 unit .
For housing 1 Mesh AP broadcast SSID 5678.
For housing 2 IAP 105 broadcast SSID 1234.
I try before , but cannot broadcast at the same time , only either mesh AP (location 1) or standalone AP (location 2) can broadcast SSID.
