FRITZ!Box 3370 Service

Wi-Fi range is too low

The range of the Wi-Fi connection between one or more wireless devices and the FRITZ!Box is too low. Even at a short distance from the FRITZ!Box, web pages load slowly, files take a long time to download, and video streams are not played correctly, for example.

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

Note:All instructions on configuration and settings given in this guide refer to the latest FRITZ!OS for the FRITZ!Box.

1 Updating FRITZ!OS and Wi-Fi software

Updates contain improvements, bug fixes, and new functions. Therefore, install the latest FRITZ!OS or software version on all of the devices:

Installing the latest FRITZ!OS for the FRITZ!Box

  1. Install the latest FRITZ!OS on the FRITZ!Box.

Installing the latest software for the wireless device

  1. Install the latest software version for the wireless device (for example Android, iOS) or the latest driver for the computer's wireless network adapter (for example using Windows Update).

    Note:Information on the update can be obtained from the device's manufacturer, for example refer to the manual. You can find the latest drivers for the FRITZ!WLAN Sticks in our download area.

2 Optimizing the FRITZ!Box's Wi-Fi settings

Automatically configuring Wi-Fi channel settings

  1. Click "Wi-Fi" in the FRITZ!Box user interface.
  2. Click "Wi-Fi Channel" ("Radio Channel") in the "Wi-Fi" ("Wireless") menu.
  3. Enable the option "Set Wi-Fi channel settings automatically (recommended)".
  4. Click "Apply" to save the settings. Now Wi-Fi connections to the FRITZ!Box are briefly cleared and then automatically re-established.

Adjusting the name of the Wi-Fi network (SSID)

  1. Click "Wi-Fi" in the FRITZ!Box user interface.
  2. Click "Wi-Fi Network" ("Radio Network") in the "Wi-Fi" ("Wireless") menu.
  3. Enter a unique name in the field "Name of the Wi-Fi network (SSID)". This prevents your wireless devices from trying to connect to the wrong wireless router if there are Wi-Fi networks with the same name in the area.
  4. Enable the option "Name of the Wi-Fi network visible". This way, all wireless devices can establish a connection to the FRITZ!Box.
  5. Click "Apply" to save the settings. All Wi-Fi connections to the FRITZ!Box are cleared when the new Wi-Fi network name is adopted. You must then reconfigure the Wi-Fi connections to the FRITZ!Box.

3 Finding the ideal location for the FRITZ!Box

  1. If possible, place the FRITZ!Box in a centrally located room. The FRITZ!Box has omnidirectional antennas. The Wi-Fi signal is therefore emitted spherically in all directions.
  2. Do not place the FRITZ!Box directly in the corner of a room.
  3. Place 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. Place the FRITZ!Box as high in the room as possible, for example on a shelf.
  5. Place the FRITZ!Box so that there are as few obstacles as possible between it and the wireless devices. Even small objects in the immediate vicinity of your FRITZ!Box can greatly reduce the range of the Wi-Fi signal. Metallic objects or objects containing water, such as radiators, refrigerators, or even houseplants, significantly reduce the quality of the Wi-Fi signal.
  6. Place the FRITZ!Box away from other radio transmitters, such as microwaves, wireless speakers, or Bluetooth devices.

Now the FRITZ!Box and the wireless devices are ideally configured. If the range of the Wi-Fi connections of individual wireless devices is still low, then the problem lies with the respective devices. The manufacturer of the wireless devices may be able to give you some troubleshooting tips.

If the range of Wi-Fi connections to the FRITZ!Box is still generally low, the Wi-Fi environment is the cause. In this case you can use a FRITZ!Repeater to increase the range and stability of the Wi-Fi connections.
