There is credible evidence that Lamarr came up with the notion of frequency hopping. Clever idea that has nothing to do with Wi-Fi. In fact, the original incarnation of Wi-Fi shared spectrum with microwave ovens and home cordless phones. My wife could jam my Wi-Fi connection by warming coffee or making a phone call. IEEE 802.11b was very susceptible to interference.
Claiming Hedy Lamarr invented Wi-Fi is a nice glamorization. She conceived frequency hopping, for which she deserves due credit. She did not invent Wi-Fi. Even Isaac Newton said he stood on the shoulders of giants.
