    You can find the latest drivers for the FRITZ!WLAN Sticks in our download area.

3 Optimizing the FRITZ!Box's wireless settings

If the wireless settings are inappropriate, you may not be able to set up a wireless connection. Therefore, the following steps are only necessary if you want to set up the wireless connection manually. Alternatively, you can set up a wireless 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. Refer to the manufacturer of the device for information on whether it supports WPS, for example consult the manual.

Preparations

  • Use a network cable to connect a computer to the "LAN 2" port on the FRITZ!Box.

Briefly disabling the MAC address filter

When the MAC address filter is enabled, new wireless devices that are unknown to the FRITZ!Box cannot connect to the FRITZ!Box. Therefore, make sure that the MAC address filter is disabled:

  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.

The FRITZ!Box's MAC address filter is now disabled. You can re-enable it as soon as you have completed the configuration of the wireless connection between the wireless device and the FRITZ!Box.

Displaying the name of the wireless network (SSID)

Some wireless devices cannot establish a wireless connection if the name of the FRITZ!Box's wireless network is not visible:

Note:Hiding the wireless network name can represent 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.

Changing the name of the wireless network (SSID)

Some wireless devices (for example Apple iPhone) cannot establish a wireless connection if the name of the wireless network contains special characters:

  1. Click "Wireless" ("WLAN") in the FRITZ!Box user interface.
  2. Click "Radio Network" in the "Wireless" ("WLAN") menu.
  3. Enter a unique name that does not contain special characters in the field "Name of the wireless radio network (SSID)".
  4. Click "Apply" to save the settings.

When you apply the new wireless network name, all wireless connections to the FRITZ!Box are cleared. You must then reconfigure wireless connections to the FRITZ!Box.
