2 Installing the latest software for the wireless devices

New software versions include adjustments for new Wi-Fi standards and bug fixes. Therefore, install the latest software on all of the wireless devices:

Installing the latest FRITZ!OS for the FRITZ!Box

Perform the following steps on a different device connected to 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 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.

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

If the Wi-Fi settings are inappropriate, you may not be able to set up a Wi-Fi connection manually. Therefore, the following steps are only necessary if you want to set up the Wi-Fi connection manually. As an alternative, you can set up a Wi-Fi connection automatically via WPS:

Note:WPS is supported by computers with Windows 10 / 8 / 7, current Intel wireless network adapters, many media players, and wireless music systems, for example. Information on whether a device supports WPS can be obtained from the manufacturer of the device, for example consult the manual.

Preparations

  1. Use a network cable to connect a computer to the "LAN 2" port on the FRITZ!Box so you can open the user interface and adjust the Wi-Fi settings.

Disabling the MAC address filter

  1. Click "Wireless" ("WLAN") in the FRITZ!Box user interface.
  2. Click "Security" in the "Wireless" ("WLAN") menu.
  3. Enable the option "Allow all new wireless devices".
  4. Click "Apply" to save the settings.

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

WPS is not available if the name of the Wi-Fi network is hidden. Also, some wireless devices cannot establish a Wi-Fi connection if the name of the Wi-Fi network is not visible:

Note:Hiding the Wi-Fi network name can pose a security risk (see article in PC World: 5 Wi-Fi security myths you must abandon now).

  1. Click "Wireless" ("WLAN") in the FRITZ!Box user interface.
  2. Click "Radio Network" in the "Wireless" ("WLAN") menu.
  3. Enable the option "Name of the wireless radio network visible".
  4. 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.

Enabling the wireless standard 802.11b

The following step is only necessary if the wireless device (for example a Fitbit wireless scale) only supports the obsolete wireless standard 802.11b:

Note:By default, the wireless standard 802.11b is disabled in the FRITZ!Box because the user data rate of all wireless devices in the 2.4 GHz frequency band is reduced when 802.11b support is enabled, even if none of the wireless devices are using this standard.

  1. Click "Wireless" ("WLAN") in the FRITZ!Box user interface.
  2. Click "Radio Channel" in the "Wireless" ("WLAN") menu.
  3. Enable the option "Adjust radio channel settings".
  4. Click "Additional Settings".
  5. Select the standard "802.11n+g+b" from the "2.4-GHz wireless standard" drop-down list.
  6. Click "Apply" to save the settings.

Disabling PMF

PMF (Protected Management Frames) encrypts the control information for establishing and using Wi-Fi connections, thus ensuring greater security. However, some wireless devices do not support PMF.

PMF is not enabled in the factory settings of the FRITZ!Box. The following step is only necessary if you changed the FRITZ!Box's Wi-Fi settings:

  1. Click "Wireless" ("WLAN") in the FRITZ!Box user interface.
  2. Click "Security" in the "Wireless" ("WLAN") menu.
  3. Disable the option "Enable support for protected registration of wireless LAN devices (PMF)".
  4. Click "Apply" to save the settings.
