With its strong Wi-Fi performance and great features, the FritzBox 5590 Fibre wins the test. If you want even faster Wi-Fi with Wifi 7, go for the 5690 Pro - and enjoy the additional ZigBee radio, which allows you to connect and control more smart home devices. In return, you have to accept compromises in terms of telephone and USB connections...

The top FritzBox 7590, 6690 and 5590 routers are suitable for large flats and houses thanks to their powerful WLAN. With their wide range of functions, they can cope with almost all requirements. The affordable 7530 AX, 6660 and 5530 offer sufficient performance for smaller households...

... Unsurprisingly, the (good) Wi-Fi performance hardly differs from the Smart 4 variant without Plus. If required, they can be expanded using the mesh function (see below). The power consumption is okay considering the performance.

If you want special features such as dual-stack service shares for internal servers or fast mass storage on the network (NAS), you will have to look elsewhere. Telekom customers who only need Internet access with particularly simple commissioning, on the other hand, are well served with the Speedport Smart 4 Plus.
