How to get the best Wi-Fi performance

Find the best position for wireless devices

Every home has its unique conditions that affect the Wi-Fi connection. How thick are the walls and what are they made of, for example? Other devices that transmit radio waves can also influence connection quality, including microwave ovens and Bluetooth devices. This makes it even more important to position your FRITZ!Box in the best possible place, i.e. as close to the center of the home as possible.

Position the FRITZ!Box so that it is not covered by other objects and there are as few obstacles as possible between it and other wireless devices. Metal objects and substances containing water interfere greatly with radio waves, as does double/triple glazing.


You can easily measure the signal strength in the different parts of your home using the FRITZ!App WLAN for Android and iOS. You can also use the app to identify sources of interference and move your FRITZ!Box or wireless devices based on the results. Also make sure that your Wi-Fi network has its own unique name. Keep in mind that you can only enjoy the best Wi-Fi with the latest Wi-Fi software for all of your devices.

More performance with Wi-Fi 6

Newer FRITZ!Box models such as the FRITZ!Box 6660 already support Wi-Fi 6, the next-generation wireless standard. In addition to higher data rates and the use of more devices at the same time, Wi-Fi 6 reduces power consumption, increasing the battery life of smartphones and other wireless devices. When purchasing new wireless devices, it's a good idea to ensure they support the new Wi-Fi 6. Find out more about the next generation in Wi-Fi in our guide.
