FRITZ!Box 7330 Service

Wireless range is too low

The range of the wireless connection (WiFi) between a notebook, smartphone, or another wireless device and your FRITZ!Box is too low. Even at a short distance from the FRITZ!Box, web pages load slowly, it takes a long time to download files, and video streams are not played correctly, for example.

Cause

  • Surrounding structural conditions (such as thickness and reinforcement of the walls) as well as other electronic devices such as wireless speakers and baby monitors influence the quality and thus the range of the wireless connection.

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

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

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

2 Installing the latest software for the wireless device

  1. 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:Refer to the manufacturer for information on how to update, for example consult the manual.
    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. Select "100%" from the drop-down list "Maximum transmitter power". If the drop-down list is not displayed, enable the Advanced View first.
      2. Click "Apply" to save the settings.

4 Enabling or refreshing the auto channel

The auto channel function allows the FRITZ!Box to check the wireless environment and automatically select the best wireless channel settings. However, since the wireless environment is constantly changing and the FRITZ!Box cannot check again as long as wireless devices are connected to it, you can also refresh the auto channel manually:

  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:When the auto channel is enabled and refreshed, all wireless connections to the FRITZ!Box are briefly cleared and then automatically reestablished.

  5. Click the "Refresh Auto Channel" button.

5 Finding the ideal location for the FRITZ!Box

  1. If possible, position the FRITZ!Box in a central location.
  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 other wireless devices. Especially metallic objects or objects containing water, for example radiators, refrigerators, or even houseplants, significantly reduce the quality of the wireless signal.
  6. Position the FRITZ!Box away from other radio transmitters, for example microwaves, wireless speakers, or Bluetooth devices.

6 Changing the name of the wireless network (SSID)

If there are other wireless networks with the same name in the immediate vicinity, wireless devices may automatically attempt to connect to the wrong wireless network. To avoid this, give the 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 without special characters in the field "Name of the wireless radio network (SSID)". Since not every wireless device support all special characters, we recommend using only standard alphanumeric characters and not symbols or special letters such as ä, ë, ö, ü, á, é, í.
  4. Click "Apply" to save the settings.

All wireless connections to the FRITZ!Box are cleared when you apply the new wireless network name. You must then reconfigure wireless connections to the FRITZ!Box.

Now the FRITZ!Box is ideally configured. If the wireless range is still too low despite these measures, then the wireless environment is causing the issue and cannot be further influenced by the FRITZ!Box.

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