What are the two requirements to connect a smart device to a home wireless network?

The key idea is that a device needs to identify the network it should join and have an address to participate on that network. First, it must know the network name (the SSID) so it can connect to the correct Wi‑Fi and, if the network is secured, provide the password to authenticate. Second, it needs an IP address so it can be addressed and exchange data with other devices on the local network (and with the router as a gateway to others). In most homes, an IP address is assigned automatically by DHCP, so you often don’t set it manually. DNS and gateway matter for reaching external sites and resources, but they aren’t required just to connect to the wireless network.
