What Wi-Fi speeds can be achieved with the FRITZ!Box?

Manufacturers state the maximum Wi-Fi speeds that can be achieved as the maximum gross data rates that are technically possible. However, the actual user data rates available for file downloads, video streams, etc., are lower.

In this guide, we tell you which factors determine the gross data rates, which user data rates you can actually achieve with the FRITZ!Box and your wireless devices, and what you can do if these data rates are too low.

1 What determines the gross data rate?

The maximum possible speed of a Wi-Fi connection (gross data rate) is determined by the wireless device with the slowest speed and depends on three factors:

  1. the wireless standard (for example Wi-Fi 5, Wi-Fi 6),
  2. the number of data streams in MIMO multi-antenna technology (for example 1x1, 4x4),
  3. the channel bandwidth (for example 20 MHz, 160 MHz).

2 Which gross data rates does the FRITZ!Box support?

You can find the gross data rates of current FRITZ!Box models in the following table. If your FRITZ!Box model is not listed here, you can find this information in the chapter "Technical Specifications > Ports and Interfaces" of itsmanual:

3 Which gross data rate does the wireless device support?

Refer to the manufacturer for information on the maximum gross data rates and other properties of the wireless device (supported wireless standards, frequency bands, data streams, and channel bandwidths), for example consult the manual. If you cannot find this information, you can refer to the current gross data rates of the wireless device that is displayed in the FRITZ!Box user interface:

  1. Click "Home Network" in the FRITZ!Box user interface.
  2. Click "Mesh" or "Home Network Overview" in the "Home Network" menu.
  3. Click "Details" next to the corresponding wireless device.
  4. Make note of the "Max. data rate possible" and "Current throughput" for the Wi-Fi connection. Each of the first values shows the gross data rate for the "upstream" (send direction) and the second value shows the gross data rate for the "downstream" (receive direction).

4 What determines the user data rate?

As with all radio technologies, Wi-Fi is a so-called "shared medium". Therefore, all of the wireless devices connected to the FRITZ!Box must share the total available gross data rates.

Since the gross data rates also include control data and overhead (protocol overhead), the actual user data rates available are lower. Under ideal conditions, the user data rates for Wi-Fi 6 are around 60-65%, for Wi-Fi 5 they are around 50%, and for Wi-Fi 4 they are around 40% of the gross data rates.

Since data packets are lost with increasing distance and when sources of interference are present and have to be resent repeatedly, the achievable user data rates are usually lower in practice.

5 How can the user data rate be measured?

We recommend using FRITZ!App WLAN to measure the user data rate and determine the influence of interference and distance on it. FRITZ!App WLAN is available for mobile devices with Android and iOS; while it is measuring, it displays the user data rate of the mobile device that can actually be achieved at the respective location. The speed of the internet connection does not matter.

Start the measurement process directly next to the FRITZ!Box by tapping "Measure Wi-Fi" in FRITZ!App WLAN and then move away from the FRITZ!Box to observe the effects of distance on the user data rate in real time.

6 How can the Wi-Fi speed be increased?

In the factory settings, the FRITZ!Box already evaluates its Wi-Fi environment and the quality of the connection of the wireless devices connected to it at regular intervals and automatically selects the best possible settings for stable and fast Wi-Fi connections. A significant increase of the Wi-Fi speed can therefore usually only be achieved by using additional FRITZ!Repeaters.

However, if the Wi-Fi speed of the connection between your wireless devices and the FRITZ!Box is always very low regardless of the distance, web pages only load slowly, or video streams stop playing, follow the steps in our guide Slow Wi-Fi connection.
