so you are telling me that i could not use the hap mini as a repeater?
It may work, or it may not. The thing is that the WiFi standard did not expect stations (clients) to be bridges, so the MAC address of the WiFi station is expected to always be the same as the one of the actual sender/recipient of the frame at station side, so there is a single field for both in the standard wireless frame. So DHCP servers that correctly assign the IP address up to the
client-id field in the DHCP message, rather than according to the source MAC address of the frame carrying that message, will assign IP addresses to all clients behind the hAP, and the hAP, if running in pseudobridge mode, will respond to ARP requests for all those addresses with its own MAC address and deliver the frames to the actual MAC address of the device connected to its Ethernet side depending on their destination IP address, but this will not work for non-IP traffic as the pseudobridge won't know any protocol field to map to a MAC address of the recipient. I haven't even ever tried how pseudobridge deals with IPv6 traffic.
With two wireless devices from the same vendor, you can use a bridge mode where the wireless frames carry all 4 MAC addresses separately, but as this frame format is not standardized, it is not compatible between different vendors supporting wireless bridging.
