Well, I think it is necessary if you have mobile devices. Anything nailed down should be connected by wire, but if it is mobile, it should get the connection. Especially if the cell phone link is not that good inside the house.
None of my mobile devices are “necessary,” though. Honestly, I could live just fine without an internet connection. Not that I’d enjoy it, but that’s not necessary.
“Necessary” is a little ambiguous. You could argue that wifi is unnecessary for a normal home network.
