A recent trend on TikTok has suggested that placing a coin on a router might improve Wi-Fi range. Some users claim that this simple trick can boost signal strength and extend coverage in their homes. The idea has gained popularity online, with many people sharing videos of themselves experimenting with the method and reporting perceived improvements in their internet connection. However, experts and technology professionals have pointed out that there is no scientific basis for this claim. Placing a coin on a router does not affect the internal components or signal transmission of the device. Wi-Fi performance is typically influenced by factors such as router placement, interference from other devices, and the quality of the internet service itself. The trend highlights how social media platforms can spread unverified tips and hacks that may seem effective but lack technical validity. While some users might feel their Wi-Fi has improved after trying the coin trick, this is likely due to coincidence or a placebo effect rather than any real change in the router’s performance. Internet service providers and tech support teams generally advise users to follow proven methods for optimizing Wi-Fi, such as positioning the router centrally in the home, reducing interference from walls or furniture, and ensuring the router’s firmware is up to date. These steps are backed by research and can make a measurable difference in internet performance.
