I use this to isolate my devices from a complex wide shared network with 1000 condo units.

It’s a WiFi to WiFi bridge. You connect one over WiFi to get internet access and it creates a separate WiFI connection for your devices. You could use it to create a segregated network for untrusted devices.

It’s also a WiFi to Ethernet bridge FWIW. Just the opposite of most routers that only work as Ethernet to WiFi.
