Slow Wi-Fi connection

The Wi-Fi connection to the FRITZ!Box is very slow. Due to the low Wi-Fi speed, web pages load slowly, files take a long time to download, or image interference or interruptions occur during video streaming, for example.

Simply proceed as described below. After each measure, check whether the problem is solved.

Note:All instructions on configuration and settings given in this guide refer to the latest FRITZ!OS for the FRITZ!Box.

1 Updating FRITZ!OS and Wi-Fi software

Updates contain improvements, bug fixes, and new functions. Therefore, install the latest FRITZ!OS or software version on all of the devices:

Installing the latest FRITZ!OS for the FRITZ!Box

  1. Install the latest FRITZ!OS on the FRITZ!Box.

Installing the latest software for the wireless device

  1. Install the latest software version for the wireless device (for example Android, iOS) or the latest driver for the computer's wireless network adapter (for example from the Intel Download Center).

    Note:Refer to the device's manufacturer for information on how to update, for example consult the manual.

2 Optimizing the FRITZ!Box's Wi-Fi settings

Setting Wi-Fi channel settings automatically

In the factory settings, the FRITZ!Box evaluates the Wi-Fi environment and the connection quality of the wireless devices at regular intervals. Based on this evaluation, it automatically selects the best Wi-Fi channel settings. If you disabled the automatic adjustment of Wi-Fi channel settings, enable it again:

  1. Click "Wi-Fi" ("Wireless") in the FRITZ!Box user interface.
  2. Click "Wi-Fi Channel" ("Radio Channel") in the "Wi-Fi" ("Wireless") menu.
  3. Enable the option "Set Wi-Fi channel settings automatically (recommended)".
  4. Click "Apply" to save the settings. Now Wi-Fi connections to the FRITZ!Box are briefly cleared and then automatically re-established.

Adjusting the name of the Wi-Fi network (SSID)

  1. Click "Wi-Fi" ("Wireless") in the FRITZ!Box user interface.
  2. Click "Wi-Fi Network" ("Radio Network") in the "Wi-Fi" ("Wireless") menu.
  3. Enter the same unique name in the fields "Name of the Wi-Fi network (SSID)" for the 2.4 GHz and the 5 GHz frequency band. If only one field is displayed, enable the Advanced View first. This prevents your wireless devices from trying to connect to the wrong wireless router if there are Wi-Fi networks with the same name in the area.
  4. Enable the option "Name of the Wi-Fi network visible". This way, all wireless devices can establish a connection to the FRITZ!Box.
  5. If you changed the name of the FRITZ!Box's Wi-Fi network (SSID), remove all special characters from the Wi-Fi network name. Since some wireless devices do not support all of the special characters allowed by the FRITZ!Box, only use letters (but not special characters such as ä, ë, ö, ü, á, é, í), numbers, and spaces.
  6. Click "Apply" to save the settings. All Wi-Fi connections to the FRITZ!Box are cleared when the new Wi-Fi network name is adopted. You must then reconfigure the Wi-Fi connections to the FRITZ!Box.

3 Finding the ideal location for the FRITZ!Box

  1. If possible, place the FRITZ!Box in a centrally located room. The FRITZ!Box has omnidirectional antennas. The Wi-Fi signal is therefore emitted spherically in all directions.
  2. Do not place the FRITZ!Box directly in the corner of a room.
  3. Place the FRITZ!Box so that it is as unobstructed as possible, i.e. not directly in back of or under an obstacle such as pieces of furniture or a heater.
  4. Place the FRITZ!Box as high in the room as possible, for example on a shelf.
  5. Place the FRITZ!Box so that there are as few obstacles as possible between it and the wireless devices. Even small objects in the immediate vicinity of your FRITZ!Box can greatly reduce the range of the Wi-Fi signal. Especially metallic objects or objects containing water, for example radiators, refrigerators, or houseplants, significantly reduce the quality of the Wi-Fi signal.
  6. Place the FRITZ!Box away from other radio transmitters, such as microwaves, wireless speakers, or Bluetooth devices.

Now the FRITZ!Box and wireless device are ideally configured and wireless devices should be able to establish fast and stable Wi-Fi connections to the FRITZ!Box.

If Wi-Fi connections to the FRITZ!Box are still slow, either internet access via the FRITZ!Box is slow or this is due to the Wi-Fi environment. In this case you can use a FRITZ!Repeater to increase the speed of Wi-Fi connections.
