How to achieve the best WiFi performance

Optimizing the wireless network

At home, the wireless network (WiFi) is usually the most common method for accessing the internet. Smartphone and tablet users are especially dependent upon stable wireless reception. Since they change their location frequently, the wireless network should ideally cover all rooms. The FRITZ!Box is already ideally configured for most wireless environments in the factory settings. If the wireless speed or network coverage is insufficient, the following simple steps will help you to optimize the wireless network.

1 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.

2 Installing the latest software

Installing the latest FRITZ!OS for the FRITZ!Box

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 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. Since the wireless environment is constantly changing, the FRITZ!Box checks it again every 6 hours, as long as no wireless devices are active at that time. You can also 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 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.

4 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" (if available).
      2. Select "100%" from the drop-down list "Maximum transmitter power". If the drop-down list is not displayed, enable the Advanced View first.
      3. Click "Apply" to save the settings.

5 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. In the field "Name of the wireless radio network (SSID)", enter a unique name for the 2.4 GHz and the 5 GHz frequency band (if applicable) 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.
