I came across this gem after seeing this meme:
Really, I thought – and did a little digging. Interesting little gem here.
Who invented WiFi? – Chris Skinner’s blog
At the height of her fame, in 1942, she developed a new kind of communications system, optimized for sending coded messages that couldn’t be “jammed.” She was building a system that would allow torpedoes and guided bombs to always reach their targets. She was building a system to kill Nazis. By the 1940s, both the Nazis and the Allied forces were using the kind of single frequency radio-controlled technology Kiesler’s ex-husband had been peddling. The drawback of this technology was that the enemy could find the appropriate frequency and “jam” or intercept the signal, thereby interfering with the missile’s intended path.
Kiesler’s key innovation was to “change the channel.” It was a way of encoding a message across a broad area of the wireless spectrum. If one part of the spectrum was jammed, the message would still get through on one of the other frequencies being used. The problem was, she could not figure out how to synchronize the frequency changes on both the receiver and the transmitter. To solve the problem, she turned to perhaps the world’s first techno-musician, George Anthiel.
Anthiel was an acquaintance of Kiesler who achieved some notoriety for creating intricate musical compositions. He synchronized his melodies across twelve player pianos, producing stereophonic sounds no one had ever heard before. Kiesler incorporated Anthiel’s technology for synchronizing his player pianos. Then, she was able to synchronize the frequency changes between a weapon’s receiver and its transmitter. On August 11, 1942, U.S. Patent No. 2,292,387 was granted to Antheil and “Hedy Kiesler Markey,” which was Kiesler’s married name at the time.
But we also have this too – debunking the black hole theory more or less:
While it’s true that Wi-Fi’s core technology has its roots in radio astronomy research, specifically in improving the clarity of weak radio signals, the idea of using it to detect black holes in space is inaccurate. Dr. Karl Crownhart’s blog on Australian Geographic explains that the signals were actually those from black holes. The technology was developed by Australian scientists at CSIRO, according to ABC News while working to improve the clarity of radio signals, not for detecting black holes.

Who knows. I myself align with the top theory. Why give the credit to a female? Wouldn’t be the first time. At least we have the patent number – forever in print to disprove any other theory:
