FRITZ!Box 4040 Service

Extending wireless range of the FRITZ!Box with a repeater

You can increase the wireless range (WiFi) of your FRITZ!Box with Internet access (access point) if you set up a FRITZ!Box 4040 for use as a repeater. This allows you to:

  • completely integrate computers, smartphones, or other network devices connected to the FRITZ!Box 4040 into your home network. You can use them to access the Internet as well as other devices in the home network. All of the functions of the FRITZ!Box (access point) are also available to them.
  • let your guests enjoy fast and secure Internet access via the guest wireless network, even when they are far from the FRITZ!Box (access point). The wireless devices used by your guests remain completely separated from your home network.

Here we show you how to set up the FRITZ!Box 4040 as a repeater.

Requirements / Restrictions

1 Configuring the FRITZ!Box (access point)

All FRITZ!Boxes are configured for use as an access point in the factory settings. If you changed the wireless settings of the FRITZ!Box with Internet access, configure the following settings in that FRITZ!Box:

Enabling the wireless network

  1. Click "Wireless" ("WLAN") in the FRITZ!Box user interface.
  2. Click "Radio Network" in the "Wireless" ("WLAN") menu.
  3. Enable the wireless network.
  4. Click "Apply" to save the settings.

Displaying the name of the wireless network (SSID)

Make sure that the wireless network name of the FRITZ!Box (access point) is 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.

Briefly disabling the MAC address filter

The FRITZ!Box's MAC address filter may not be enabled during the configuration procedure:

  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" in the "Restricting wireless LAN access" section.

    Note:With some FRITZ!Box models you will find this setting under "Wireless (WLAN) > Radio Network" instead of under "Wireless (WLAN) > Security".

  4. Click "Apply" to save the settings.

The 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 FRITZ!Box (repeater) and the FRITZ!Box (access point).

Configuring the operating mode

  1. Click "Wireless" ("WLAN") in the FRITZ!Box user interface.
  2. Click "Mesh/Repeater" or "Repeater" in the "Wireless" ("WLAN") menu.
  3. Enable the option "Access point".
  4. Click "Apply" to save the settings.

2 Configuring the FRITZ!Box (repeater)

Preparations

  1. Use a network cable to connect a computer to a LAN port on the FRITZ!Box you would like to set up as a repeater.
  2. If the computer is already connected with the FRITZ!Box (access point), clear the network connection between the computer and the FRITZ!Box (access point).

Adjusting the wireless settings of the FRITZ!Box (access point)

Configure the following settings in the FRITZ!Box (repeater) so that your wireless devices can always automatically connect to the FRITZ!Box with the strongest signal (wireless roaming):

  1. Click "Wireless" ("WLAN") in the FRITZ!Box user interface.
  2. Click "Radio Network" in the "Wireless" ("WLAN") menu.
  3. For the frequency band being used, enter the same "Name of the wireless radio network (SSID)" that you entered in the FRITZ!Box (access point).
  4. Click "Apply" to save the settings.
  5. Click "Security" in the "Wireless" ("WLAN") menu.
  6. Enable the option "WPA encryption".
  7. Select "WPA2 (CCMP)" for the "WPA mode".

    Note:If you still use wireless devices that do not support WPA2, you can use the setting "WPA + WPA2". If you select this setting, your wireless devices will automatically use the safest WPA mode for wireless connections.

  8. In the "Network key" field, enter the same network key that you entered in the FRITZ!Box (access point).
  9. Click "Apply" to save the settings.

Configuring the operating mode

  1. Click "Wireless" ("WLAN") in the FRITZ!Box user interface.
  2. Click "Mesh/Repeater" or "Repeater" in the "Wireless" ("WLAN") menu.
  3. Enable the option "Repeater".
  4. Under "Access Point Selection", search for the name of the wireless network (SSID) of the FRITZ!Box (access point) and select it.

    Note:If the FRITZ!Box (access point) is not listed, decrease the distance between it and the FRITZ!Box (repeater) and click the "Refresh List" button.

  5. Enter the network key of the FRITZ!Box (access point) in the "Network key" field.
  6. Click "Apply" to save the settings.

Now the wireless connection between both FRITZ!Boxes is established.

3 Finding the ideal location for the FRITZ!Box (repeater)

  1. Select a location for the FRITZ!Box (repeater) where the wireless connection between other wireless devices (for example smartphones, tablets) and the FRITZ!Box (access point) is flawless.
  2. Do not position the FRITZ!Box (repeater) directly in the corner of a room.
  3. Position the FRITZ!Box (repeater) 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. Position the FRITZ!Box (repeater) as high in the room as possible, for example on a shelf.
  5. Make sure that there are as few obstacles as possible between the FRITZ!Box (repeater) and the FRITZ!Box (access point). In particular, metallic objects or objects containing water, for example radiators, a refrigerator, or even houseplants, significantly reduce the quality of the wireless signal.
  6. Position the FRITZ!Box (repeater) so that it is away from other transmitters, for example microwaves, wireless speakers, or Bluetooth devices.

4 Opening the FRITZ!Box user interface
