Coin on your Wi Fi router Does it boost speed Experts say no

The penny trick comes from a wireless myth

A viral tip claims placing a coin on your Wi Fi router can boost internet speed. But experts say it does nothing, because Wi Fi performance depends on precise antenna design and signal behavior, not random metal objects. Worse, it could interfere with hardware or ports, risking damage. The penny appeal persists due to a misunderstanding of how wireless signals work.
