Who invented Wi-Fi?

A wireless network called ALOHAnet was created in 1971 that connected the Hawaiin islands. Ethernet and Wi-Fi can trace some of their history back to that.

But it was in 1991 that NCR Corporation (which began as a cash register company) and AT&T (which began as a phone company) created the precursor to Wi-Fi as a way of linking cash registers called WaveLAN.

It became so popular that eventually the Institute of Electrical and Electronics Engineers (IEEE) created the 802.11 standard that we now know as Wi-Fi. In 1999, the Wi-Fi Alliance formed as a trade association to trademark Wi-Fi.
