Can 5G blocking paint effectively reduce Wi-Fi interference from neighboring networks in apartment buildings?

The video explores whether specialized EMF-blocking paint, originally designed to block 5G signals, can improve Wi-Fi performance by reducing interference from neighboring networks. Linus and his team tested the Warmore RFIE50 paint using advanced Wi-Fi 7 routers to measure performance before and after application. The concept builds on the principle that if the paint can block external signals from penetrating a space, it might also prevent interference from nearby Wi-Fi networks. This is particularly relevant in dense living situations like apartments, where multiple overlapping networks can significantly degrade wireless performance. The testing approach provides practical insights into whether this DIY solution could help residents in crowded wireless environments achieve better home network performance by creating a more isolated signal environment.
