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 additional FRITZ!Boxes to be used as repeaters. This allows you to:

  • completely integrate network and telephony devices (for example computers, smartphones) connected to the FRITZ!Box (repeater) into your home network. You can then use all of the Internet and telephony services set up in the FRITZ!Box with them.
  • allow your guests to use the guest wireless network and enjoy fast and secure Internet access, 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 an additional FRITZ!Box as a repeater. Instead of using a FRITZ!Box, you can also use a FRITZ!WLAN Repeater or a wireless repeater from another manufacturer.

Important:The instructions for configuring the FRITZ!Box (access point) are valid for the FRITZ!Box model given above these instructions. You can find guides for other models in the "Service" area of the respective FRITZ!Boxes on avm.de.

Requirements / Restrictions

  • All of the FRITZ!Boxes involved must support the repeater function.
  • In order to join the guest network of the FRITZ!Box (access point), FRITZ!OS 6 or later must be installed on the FRITZ!Box (repeater).
  • The wireless network name (SSID) of the FRITZ!Box (access point) must be visible.

Important:Some of the settings described here are only displayed if the advanced view is enabled in the user interface. The configuration procedure and notes on functions given in this guide refer to the latest FRITZ!OS

1 Configuring the FRITZ!Box (access point)

The FRITZ!Box is already configured for use as an access point in the factory settings. If you changed the FRITZ!Box's wireless settings, configure the following settings:

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 for the 2.4 GHz frequency band.
  4. Enable the wireless network for the 5 GHz frequency band.
  5. Click "Apply" to save your 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 your settings.

Briefly disabling the MAC address filter

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

  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 your 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 "Repeater" in the "Wireless" ("WLAN") menu.
  3. Enable the option "Access point".
  4. Click "Apply" to save your settings.

2 Configuring the FRITZ!Box (repeater)

Preparations

  • 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.
    • Only 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 your 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 your settings.

Configuring the operating mode

  1. Click "Wireless" ("WLAN") in the FRITZ!Box user interface.
  2. Click "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.

    Important: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.

    Note:Regardless of the frequency band being used for the wireless connection between both FRITZ!Boxes, as a rule wireless devices can connect to the FRITZ!Box (access point) as well as the FRITZ!Box (repeater) using either frequency band (if the FRITZ!Box being used as the repeater can use both frequency bands simultaneously).

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

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

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

  • 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.
  • Do not position the FRITZ!Box (repeater) directly in the corner of a room.
  • 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.
  • Position the FRITZ!Box (repeater) as high in the room as possible, for example on a shelf.
  • 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 a refrigerator, radiator, houseplants) significantly reduce the quality of the wireless signal.
  • Position the FRITZ!Box (repeater) so that it is away from other transmitters (for example microwaves, baby monitors, wireless speakers, Bluetooth devices).

4 Opening the FRITZ!Box user interface

Opening the user interface of the FRITZ!Box (access point)

  • Enter fritz.box in the address bar of the web browser.

Opening the user interface of the FRITZ!Box (repeater)

  1. Click "Home Network" in the user interface of the FRITZ!Box (access point).
  2. Click "Home Network Overview" in the "Home Network" menu.
  3. Click on the link for the FRITZ!Box (repeater),
    • or:
  • Enter the DHCP host name of the FRITZ!Box (repeater), for example "attic", in the address bar of the web browser,
    • or:
  • Enter the IP address that the FRITZ!Box (access point) assigned to the FRITZ!Box (repeater) (for example 192.168.178.25) in the address field of the web browser.

    Note:You can find the IP address of the FRITZ!Box (repeater) in the user interface of the FRITZ!Box (access point) under "Home Network > Home Network Overview > Network Connections".

5 Configuring the FRITZ!Box (repeater) for telephone calls
