I have a full Windows domain controller that provides the Ethernet network for the house, including DHCP, DNS, and NAT to the Internet. We also have an old Apple AirPort providing our main WiFi network. I have two (2) Raspberry Pi devices one RPi2 one RPi3, and I have successfully bridged them so they can deliver WiFi to the hard-to-reach places in the house, but I've given them unique WiFi names. They each have different static IP addresses, and I am currently using the /etc/network/interfaces config file.
I would like to have these 2 RPis offer the same network name as the main WiFi; is it possible to change the configuration to match the WiFi name and password without interference? I imagine so, but I wasn't sure whether anyone else had tried this.
