Does WiFi Have the Power to Travel Through Walls?

The video explains how Wi-Fi works using radio waves, which have lower frequency and longer wavelength than light waves, allowing them to pass through walls and obstacles. It discusses factors that can interfere with Wi-Fi signals, such as water and metal, and provides tips to improve signal strength, like positioning the router centrally and updating firmware. The video concludes by highlighting the importance of understanding Wi-Fi's properties to ensure strong and reliable connectivity.

What is the primary reason Wi-Fi signals can travel through walls?

• They have a higher frequency than light waves.

• They are a form of visible light.

• They have a lower frequency and longer wavelength than light waves.

• They are not affected by any materials.

Which of the following materials is most likely to weaken Wi-Fi signals?

• Plastic

• Water

• Glass

• Wood

What is one way to improve the strength of your Wi-Fi signal?

• Position the router on a higher surface.

• Keep the router in a closed cabinet.

• Place the router next to a microwave.

• Place the router near metal objects.

Why might a Wi-Fi signal be weaker in certain areas of a house?

• The signal is too strong.

• The router is too close to the device.

• The signal is being absorbed by water or reflected by metal.

• The router is placed on a high surface.

What is a recommended solution if your Wi-Fi signal is weak in some parts of your home?

• Use a Wi-Fi extender or mesh network.

• Place the router in a corner of the house.

• Turn off all electronic devices.

• Use a wired connection only.
