FRITZ!Box 7390 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.

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 your 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

  • 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. Click "Additional settings".
      2. Select "100%" from the drop-down list "Maximum transmitter power".
      3. Click "Apply" to save the settings.

4 Enabling or refreshing the auto channel

When the auto channel is enabled, the FRITZ!Box checks the wireless environment and automatically selects the most suitable wireless channel settings. The allocation of the frequency band can change significantly over the course of the day, though. The FRITZ!Box does not refresh the auto channel as long as wireless devices are still connected with it. However, you can 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:When you enable or refresh the auto channel, all wireless connections to the FRITZ!Box are cleared and automatically re-established.

  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 so that it is 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 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. In the fields "Name of the wireless radio network (SSID)", enter a unique name for the 2.4 GHz and the 5 GHz frequency band without special characters. If only one field is displayed, enable the Advanced View first. 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.

7 Establishing a wireless connection to the 5 GHz frequency band

The FRITZ!Box provides a wireless network in the 2.4 GHz as well as the 5 GHz frequency band. The 5 GHz frequency band is less affected by interference. Therefore, switch to this frequency band if your wireless devices support the 5 GHz frequency band:

Note:Not all wireless devices support the 5 GHz frequency band.
FRITZ!WLAN Stick AC 430, FRITZ!WLAN Stick AC 860, and FRITZ!WLAN Stick N (v2) support the 5 GHz frequency band.

  1. Click "Wireless" ("WLAN") in the FRITZ!Box user interface.
  2. Click "Radio Network" in the "Wireless" ("WLAN") menu.
  3. Enable the option "Wireless radio network enabled" in the "5-GHz Frequency Band" section.
  4. Enter a different name in the field "Name of the wireless radio network (SSID)" so that you can distinguish the 5 GHz wireless network from the 2.4 GHz wireless network in the future. If only one field is displayed, enable the Advanced View first.

    Important:Not all wireless devices support all special characters. Therefore, only use standard alphanumeric characters and not symbols or special letters such as ä, ë, ö, ü, á, é, í in the wireless network name.

  5. Click "Apply" to save the settings.
  6. Establish a wireless connection to the FRITZ!Box wireless network with the name (SSID) that you assigned to the 5 GHz frequency band.

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.
