AVM FritzBox 7590 AX in the test: just missed the top spot


Rumors have been circulating for a long time about a new FritzBox top model with Wifi 6 (WLAN-ax) – after all, the manufacturer AVM has already brought some mid-range models with the new WLAN standard onto the market: the FritzBox 7530 AX for DSL, 6660 Cable for Cable and 5530 fiber for fiber optics. After AVM recently launched the FritzRepeater 6000 (also with WiFi 6), the company has now actually released a new edition of the DSL front-runner 7590: the FritzBox 7590 AX. Here is the test.

FritzBox 7590 AX: Wifi 6 is rarely better

The big innovation of the FritzBox 7590 AX is Wifi 6. With devices that can also use this standard, a significantly higher speed is theoretically possible. The problem: So far, WiFi 6 devices have a maximum of two antennas, so the better WiFi performance of the standard cannot be fully exploited. This was also shown by the test.

COMPUTER BILD recorded the WiFi speed of the router to a PC network card with WiFi 6 (two antennas) and to a card with the older standards WiFi-ac and WiFi-n (four antennas) – the 7590 AX also uses these standards . Result: Wifi 6 offered an advantage in just three of a total of 16 measurement scenarios. In all other cases, the older standards achieved higher speeds.
In the 5 gigahertz frequency band, the FritzBox 7590 AX was a bit faster than the “normal” 7590. The AX achieved a maximum average speed of 922 megabits per second (Mbps). That is quite a lot, but other Wifi-6 routers such as the Telekom Speedport Smart 4 manage over 1,500 Mbps with the new standard. For most households, the performance of the 7590 AX should easily be sufficient, because even at a good 900 Mbps, many devices can be quickly supplied with data at the same time – or a single computer with a high-performance network card, for example.

On the 2.4 gigahertz frequency, however, the FritzBox 7590 AX performed slightly worse than its predecessor: While the FritzBox 7590 achieved up to 619 Mbps, the 7590 AX already reached 442 Mbps.

Speed ​​comparison FritzBox 7590 AX and 7590
Compared to its predecessor FritzBox 7590, the speed of the 7590 AX was slightly higher at 5 gigahertz, but quite a bit lower at 2.4 gigahertz.

In addition to the speed boost, Wifi 6 offers some improvements:

  • Spatial re-use: WiFi-6 routers can control the timing of the data transmissions in a targeted manner so that several neighboring routers also transmit without interference on the same channel.
  • BSS Coloring: The function reduces waiting times in overcrowded networks. End devices use this to determine whether their own or a third-party WLAN is blocking the selected channel. Instead of waiting until the channel in the foreign network is no longer overcrowded, the end devices continue to send data.
  • OFDMA: The router negotiates the connection with several end devices at the same time and divides the individual WLAN channels into smaller sub-areas in order to send data packets more efficiently.
  • Target Wake Time: End devices switch to standby mode as soon as they do not transmit via WLAN. If you want them to send and receive again, they wake up immediately. This not only applies to end devices that can transmit via WiFi 6, but also to all smartphones, tablets & Co., since the router simply manages the data streams more intelligently.
These innovations make sense in principle, but they only show their strengths when a large number of devices come together – for example in football stadiums or at airports. In the WLAN at home, the well-known mesh functions, with which, for example, the predecessor 7590 optimized WLAN management, are more useful. Devices in the AVM network are always automatically connected to the fastest frequency (band steering) and to the router or repeater with the strongest signal (access point steering). Thanks to multi-user MIMO (MU-MIMO), the FritzBox also sends to several devices at the same time. One advantage of the new Wifi 6 standard: the 7590 AX can now receive data from several compatible devices in parallel.

From a purely visual point of view, the FritzBox 7590 AX hardly differs from its predecessor.

Apart from Wifi 6, the 7590 AX and its predecessor are similar in many respects: numerous connections, simple operation, and a large selection of functions. The power consumption of the 7590 AX is slightly higher at 10.5 watts. Small change in details: The housing of the new AVM router is slightly higher and has ventilation slots on the side.

FritzBox 7590 AX: price and release

The FritzBox 7590 AX is already available in stores. It costs 269 euros (RRP).
