My Local Area Network devices are six smart phones, three laptops, a printer, and a computer. The three laptops and six smart phones are connected to the wifi. and my computer and printer is connected to the modem by wire.
I've once had that OMG moment when I first learned that there were to different modems to connect to the wifi and by wire because I thought it was always connected with one modem. Something I would tell people that they need to know about having ISP/Home network is that everything in your house that is connected to the internet, it have to be connected to something first to get connection to the internet such as a modem.
