The weirdest things that mess up wi-fi - and how to improve your signal

Common household items, particularly microwave ovens, can interfere with 2.4 GHz Wi-Fi signals due to shared frequency bands. Understanding these physical disruptions can help users optimize their home network performance.
Why it matters
As reliance on wireless connectivity grows, identifying and mitigating signal interference is essential for maintaining efficient digital infrastructure.

The world runs on wi-fi, but strange things can stand in its way – including your lunch.
Alex Hills is a pioneer: he was among the first people on Earth to ever battle their wi-fi connection.
In 1993, he led the team that built one of the first large wi-fi networks, as a professor at Carnegie Mellon University in the US.
Hills tells the story in his book, wi-fi and the Bad Boys of Radio. But "Bad Boys" isn't a reference to his ragtag bunch of internet cowboys – it's the name he gave to the processes that stand in the way of smooth-running wi-fi.
Your home may be filled with bad boys of its own, doing everything they can to interrupt your memes. Some such disruptors are unsurprising, like thick walls. Others are a little bizarre.
