## Tips to Keep in Mind When Using Wi-Fi
In the modern era of the 4th industrial revolution, many people opt for Wi-Fi (Wireless Fidelity) to connect electronic devices such as laptops, tablets, smart TVs, and mobile phones to the Internet or to each other. Using Wi-Fi brings convenience and cost savings compared to traditional wired networks, giving users more flexibility in connecting devices.

Turning off your Wi-Fi router will clear its cache.
According to scientific research, Wi-Fi does not have a significant impact on human health. The electromagnetic waves used in Wi-Fi networks are non-ionizing radiation, meaning they do not have enough energy to cause cellular changes or chemical reactions in the human body. However, when using Wi-Fi, it is important to maintain a safe distance from the router to avoid any potential adverse effects.
Additionally, if you have a Wi-Fi router in your home, don’t forget to turn it off before going to bed. For smart routers, this can be easily done remotely through a mobile app. For other types of routers, you can manually turn them off or use a timer to automate the process.
Each time you turn off your Wi-Fi router, it clears its cache, resulting in a smoother and faster wireless connection the next morning. Besides maintaining a seamless internet speed, turning off your Wi-Fi router before bedtime also enhances network security by reducing the risk of potential hacker attacks.
## Optimal Placement of Your Wi-Fi Router for Stronger Signal
+ Place the router in the center of your house: Wi-Fi signals are emitted in all directions, so placing the router in a corner will result in uneven coverage. Walls and partitions can also cause interference and weaken the signal.
+ Mount the router in an elevated position: Wi-Fi signals from the router’s antenna tend to spread downward. Therefore, placing the router on the floor will not optimize signal transmission. Mount the modem at least 1 meter above the ground for the most stable connection.

Optimal placement of your Wi-Fi router for stronger signal
+ Place the modem near frequently used areas.
+ Position the modem in a location with minimal obstacles.
+ Keep the modem in a cool place.
