Research on electromagnetic radiation from WiFi networks operating at 2.4 GHz and 5 GHz bands.
Your WiFi router is the silent workhorse of modern connectivity, broadcasting radiofrequency (RF) electromagnetic fields 24 hours a day to keep your devices online. Operating primarily at 2.4 GHz and 5.8 GHz frequencies, these ubiquitous devices emit the same type of radiation as cell towers and cell phones, just at lower power levels.

Scientists exposed purified DNA to microwave radiation between 2.00 to 8.75 GHz at non-thermal power levels and found it caused both single and double strand breaks in the genetic material. The damage required the presence of small amounts of copper and increased with both microwave power and exposure duration. This demonstrates that microwave radiation can directly damage DNA even without heating effects.
