Can a wireless router cause problems with pacemaker?

Wireless routers operate using radiofrequency signals, which are generally considered safe and unlikely to interfere with pacemakers. Modern pacemakers are designed to be resistant to electromagnetic interference from common household devices, including routers. However, individuals with pacemakers should maintain a safe distance from the router and consult their healthcare provider for personalized advice. It's always best to err on the side of caution and follow medical guidance.
