Your Wi-Fi signal is like a radio. It gets louder when it passes through doors and walls. You may not be able hear music if you are playing music in one area and you move to another room or down to the basement. You can turn on the radio to hear certain sounds with less interference. It may also play slightly louder on some channels.You can think about your Wi-Fi signal the same way. It will weaken over time, particularly as it passes through walls and floors.
