Benefits of running 2 Wi-Fi networks from the same router? What are the downsides? (I don't know if there is a better community for this question) (discuss.tchncs.de)

I am worried that there is not really a benefit of doing that, just more noise and energy consumption.

The APs know who the Wi-Fi clients are and just drops traffic between them. This is called client/station isolation. It’s often used in corporate to 1) prevent wireless clients from attacking each other (students, guests) and 2) to prevent broadcast and multicast packets from wasting all your airtime. This has the downside of breaking AirPlay, AirPrint and any other services where devices are expected to talk to each other.
