FRITZ!Box's Wi-Fi network cannot be found

One or several notebooks, smartphones, or other wireless devices cannot find the FRITZ!Box's Wi-Fi network. When it searches for Wi-Fi networks, it does not display the name of the FRITZ!Box's Wi-Fi network (SSID).

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 Enabling the wireless network adapter

Some notebooks have a special switch or a key combination that can be used to switch integrated Wi-Fi network adapters on and off:

  1. Enable the wireless adapter of the wireless device that you want to connect to the FRITZ!Box's Wi-Fi network.

    Note:Information on on enabling it can be obtained from the manufacturer, for example refer to the manual.

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

Perform the following steps on a different device connected to the FRITZ!Box:

Important:If you cannot access the FRITZ!Box with any device, proceed as described in the guide FRITZ!Box user interface cannot be opened.

Enabling the 2.4 GHz und 5 GHz frequency bands

Many wireless devices only support Wi-Fi connections in the 2.4 GHz frequency band. To ensure that the wireless device can establish a connection to the FRITZ!Box, enable the 2.4 GHz and 5 GHz frequency band in the FRITZ!Box:

  1. Click "Wi-Fi" in the FRITZ!Box user interface.
  2. Click "Wi-Fi Network" ("Radio Network") in the "Wi-Fi" ("Wireless") menu.
  3. In the section "Active Frequency Bands", enable the Wi-Fi network for the 2.4 GHz and 5 GHz frequency band.
  4. Click "Apply" to save the settings.

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

  1. Click "Wi-Fi" in the FRITZ!Box user interface.
  2. Click "Wi-Fi Network" ("Radio Network") in the "Wi-Fi" ("Wireless") menu.
  3. Disable the option "Different names for the Wi-Fi networks on 2.4 and 5 GHz". This way, the FRITZ!Box uses the same name for the 2.4 GHz and 5 GHz frequency bands and can steer wireless devices into the frequency band that is ideal in the given situation ("band steering").
  4. Enable the option "Name of the Wi-Fi network visible". This way, all wireless devices can establish a connection to the FRITZ!Box and the FRITZ!Box can optimally control wireless devices in the Mesh ("Mesh Wi-Fi Steering").
  5. Click "Apply" to save the settings. If the wireless devices were only connected to the 5 GHz frequency band with a different name, you must then reconfigure the Wi-Fi connection on those devices.

Automatically configuring Wi-Fi channel settings

In the factory settings, the FRITZ!Box evaluates the Wi-Fi environment and the quality of the connection 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 them again:

  1. Click "Wi-Fi" 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.

3 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 using Windows Update).

    Note:Information on the update can be obtained from the device's manufacturer, for example refer to the manual. You can find the latest drivers for the FRITZ!WLAN Sticks in our download area.

4 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. Metallic objects or objects containing water, such as radiators, refrigerators, or even 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.

5 Testing a different wireless device

  1. Test whether a different wireless device can find the FRITZ!Box's Wi-Fi network.
    • If the other wireless device can find the FRITZ!Box's Wi-Fi network, the first wireless device may be defective.
