What’s your evidence, Richard Easton??!?
Wifi doesn’t use frequency hopping. That’s bluetooth.

Frequency Hopping Spread Spectrum PHY of the 802.11 Wireless LAN Standard
Edit: h3ndrik@feddit.de is correct. FHSS was quickly dropped for DSSS and OFDM, and FHSS is not used in any modern WiFi specs. You can see the list in table 7.6 here https://www.pearsonitcertification.com/articles/article.aspx?p=1329709&seqNum=4
It may be dropped, but it was used in the beginning
Wouldn’t that not still make her the mother of Wifi?
