FRITZ!Box 3390 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, files take a long time to download, 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 therefore the range and speed of the wireless connection.

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 Installing the latest FRITZ!OS for the FRITZ!Box

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

2 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.

3 Automatically configuring wireless channel settings

In the factory settings, the FRITZ!Box evaluates its wireless environment and the quality of the connection of the wireless devices connected to it on a regular basis and then automatically selects the current ideal wireless channel settings. If you disabled the automatic adjustment of wireless channel settings, enable it again:

  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. Now wireless connections to the FRITZ!Box are briefly cleared and then automatically reestablished.

4 Finding the ideal location for the FRITZ!Box

  1. If possible, place the FRITZ!Box in a central location. FRITZ!Box has omnidirectional antennas. The wireless 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 coverage area of the wireless signal. Metallic objects or objects containing water, for example radiators, refrigerators, or even houseplants, significantly reduce the quality of the wireless signal.
  6. Place the FRITZ!Box away from other radio transmitters, for example microwaves, wireless speakers, or Bluetooth devices.

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. Enter the same unique name in the fields "Name of the wireless radio network (SSID)" for the 2.4 GHz and the 5 GHz frequency band. If only one field is displayed, enable the Advanced View.
  4. Click "Apply" to save the settings.

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

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

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