AVM has been pushing for some time the mesh technique. FRITZ-Mesh is intended to seamlessly integrate repeaters and powerline devices with WiFi into the WiFi and enable problem-free switching between the individual WiFi cells by means of roaming. The result: Significantly more powerful WiFi with more range. At least in theory, because in practice there are often problems with disconnections and slow WiFi. But they can be easily solved.
Update FritzBox and FritzRepeater
Before you get started, you should make sure that all your Fritz devices have the latest firmware. To do this, first log in to all devices and install any necessary updates. Modern FritzOS versions also have an auto-update function, which you can activate under System -> Update. Then restart all devices by first unplugging all devices and then first plugging in the FritzBox and then the remaining Fritz devices.
Check mesh status
After the restart, checks whether all devices are set up as mesh devices. To do this, you have to select the Home Network -> Mesh option in the FritzBox and look for the small Mesh symbol here. If it appears on all repeaters, everything is OK. If repeaters are not displayed with the mesh symbol, either the firmware is not up-to-date or the setup failed: Resets the affected repeater and sets it up again.
FritzBox-Mesh: Assign fixed IP addresses for all devices
Last but not least, you should set up fixed IP addresses for all devices in the WLAN that have problems with the mesh network. Experience has shown that these are primarily Apple devices such as the iPhone, iPad or Mac, but it makes sense to simply give all devices a fixed IP in the home network to avoid conflicts. This is exactly what can happen with WLAN roaming.
You can easily call up the function by clicking on Home Network -> Network in the FritzBox menu and clicking on the pen symbol next to each individual device. This is how you reach the settings for the device in the WLAN. Tick “Always assign the same IP address to this WLAN device” and then click on “OK”. Repeat this with all wireless devices. Your Fritz mesh network should then work properly.
