FRITZ!Box 3272 – Service

Wireless range is low

The range of the wireless connection (WiFi) between a wireless device (for example a notebook, smartphone, tablet) and your FRITZ!Box is low.


  • Wireless devices with software (for example drivers, firmware) that is out of date, sources of interference in the vicinity, structural conditions (for example thickness and reinforcement of the walls), as well as other devices that emit radio waves, such as microwaves and baby monitors, influence the quality and thus the range of a wireless connection.

Note:The configuration procedure and notes on functions given in this guide refer to the latest FRITZ!OS for your FRITZ!Box.

Simply proceed as described below. After each measure, check whether the issue persists.

1 Installing the latest FRITZ!OS for the FRITZ!Box

2 Installing the latest software for the wireless device

  • Install the latest driver for your computer's wireless network adapter or the latest operating system (for example Android, iOS) for the wireless device.

    Note:You can find information on updating the wireless network adapter or wireless device in its manual, or consult the manufacturer directly.
    You can find the latest drivers for the FRITZ!WLAN Sticks in our download area.

3 Setting the maximum transmitter power

  1. Click "Wireless" ("WLAN") in the FRITZ!Box user interface.
  2. Click "Radio Channel" in the "Wireless" ("WLAN") menu.
  3. If the option "Set radio channel settings automatically (recommended)" is enabled, proceed with the following section.
    • If the option "Adjust radio channel settings" is enabled:
      1. Click "Additional settings".
      2. Select "100%" from the drop-down list "Maximum transmitter power".
      3. Click "Apply" to save the settings.

4 Identifying sources of interference

  1. Turn off all devices that could interfere with the wireless network.

    Note:All devices that emit radio waves are possible sources of interference. These include other wireless devices, wireless speakers, Bluetooth devices, baby monitors or microwaves, for example.

  2. Check whether the wireless connection is still impaired.
    • If the wireless connection is no longer impaired:
      1. Turn the devices back on, one after the other.
      2. Each time you turn on a device, check whether the wireless connection is impaired again.
        • If you identify a device or devices causing interference, you have the following options:
          • Leave the devices that cause interference turned off,
            • or:
          • Enable or refresh the auto channel (see the section "Enabling or refreshing the auto channel"),
            • or:
          • Find the ideal location for the FRITZ!Box (see the section "Finding the ideal location for wireless devices").

5 Enabling or refreshing the auto channel

If the auto channel is enabled, the FRITZ!Box checks the wireless environment and automatically selects the optimum wireless channel settings. However, the allocation of the frequency bands can change significantly over the course of the day. The FRITZ!Box does not refresh the auto channel as long as wireless devices are still connected with it. You can therefore manually refresh the auto channel at any time:

  1. Click "Wireless" ("WLAN") in the FRITZ!Box user interface.
  2. Click "Radio Channel" in the "Wireless" ("WLAN") menu.
  3. Enable the option "Set radio channel settings automatically (recommended)".
  4. Click "Apply" to save the settings.

    Note:All wireless connections to the FRITZ!Box are cleared and then automatically re-established when you enable or refresh the auto channel.

  5. Click the "Refresh Auto Channel" button.

6 Finding the ideal location for wireless devices

  1. If possible, position the FRITZ!Box in a room that is centrally located.
  2. Do not position the FRITZ!Box directly in the corner of a room.
  3. Position 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. Position the FRITZ!Box as high in the room as possible, for example on a shelf.
  5. Position the FRITZ!Box so that there are as few obstacles as possible between it and the other wireless devices. 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 so that it is away from other transmitters, for example microwaves, wireless speakers, or Bluetooth devices.
  7. For testing purposes, position the FRITZ!Box and the wireless device as close as possible.

    Note:Once you have ruled out all other sources of error, you can increase the distance between the two devices again.

7 Changing the name of the wireless network (SSID)

If there are other wireless networks with the same name in the vicinity, wireless devices may automatically attempt to connect to the wrong wireless network. To avoid this, give your FRITZ!Box a unique name:

  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)". Since not all wireless devices support all special characters, we recommend using only standard Latin letters (not letters such as ä, ë, ö, ü, á, é, í) and numbers.
  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.

Now the FRITZ!Box is ideally configured and you will achieve the greatest possible wireless range between your wireless devices and the FRITZ!Box. If the wireless range is still too low despite these measures, then this is due to the wireless environment and cannot be influenced by the FRITZ!Box.

Note:You can use a FRITZ!WLAN Repeater to extend the range of your wireless network quickly and easily.
