Wifi doesn't use frequency hopping. That's bluetooth.

Frequency Hopping Spread Spectrum PHY of the 802.11 Wireless LAN Standard

Edit: [email protected] 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

But that's not part of 802.11n or 802.11g or "a" or what we call "Wifi"... 802.11 in itself is a pretty long standard, including all kinds of different things.
