To improve your Wi-Fi signal transmission at home, consider repositioning your router to a central, elevated location away from walls and electronic interference. Use a modern router with the latest Wi-Fi standards, and minimize signal obstructions like metal objects or thick walls. You might also benefit from using a Wi-Fi extender or upgrading to a mesh network system for broader coverage. Additionally, ensure your router’s firmware is up to date and choose less congested wireless channels to enhance performance.
