FRITZ!Box 7360 Service

Wireless range is low

The range of the wireless connection (WiFi) between a wireless device (for example a notebook, smartphone, tablet) and your FRITZ!Box is low.

Cause

  • Wireless devices with software (for example drivers, firmware) that is out of date, sources of interference in the vicinity, structural conditions (for example thickness and reinforcement of the walls), as well as other devices that emit radio waves, such as microwaves and baby monitors, influence the quality and thus the range of a 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 issue 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:You can find information on updating the wireless network adapter or wireless device in its manual, or consult the manufacturer directly.
    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. Check which wireless channel setting is enabled.
    • 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 your settings.

4 Changing the name of the wireless network (SSID)

If there are other wireless networks with the same name in the 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. Enter a name of your choice that does not contain special characters in the field "Name of the wireless radio network (SSID)".

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

  4. Click "Apply" to save your settings.

When you apply the new wireless network name, all wireless connections to the FRITZ!Box are cleared. You must then reconfigure wireless connections to the FRITZ!Box.

5 Finding the ideal location for wireless devices

  • If possible, position the FRITZ!Box in a room that is centrally located.
  • Do not position the FRITZ!Box directly in the corner of a room.
  • 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.
  • Position the FRITZ!Box as high in the room as possible, for example on a shelf.
  • Position the FRITZ!Box so that there are as few obstacles as possible between it and the other wireless devices. In particular, metallic objects or objects containing water (for example a refrigerator, houseplants) significantly reduce the quality of the wireless signal.
  • Position the FRITZ!Box so that it is away from other transmitters (for example microwaves, baby monitors, wireless speakers, Bluetooth devices).
  • For testing purposes, position the FRITZ!Box and the wireless device as close as possible.

    Note:Once you have ruled out all other sources of error, you can increase the distance between the two devices again.

6 Identifying sources of interference

  1. Turn off all devices that could interfere with the wireless network, one after the other.

    Note:All devices that emit radio waves are possible sources of interference. These include other wireless devices, wireless speakers, Bluetooth devices, baby monitors or microwaves, for example.

  2. After you have turned off a device, check whether the wireless connection is still impaired.

Once you have identified a device that causes interference, you can either leave it turned off or try to avoid the interference by setting the channel manually.

7 Selecting the best wireless channel

  1. Click "Wireless" ("WLAN") in the FRITZ!Box user interface.
  2. Click "Radio Channel" in the "Wireless" ("WLAN") menu.
  3. Use the graph "Use of the Wireless LAN Channels" to determine which channel in the lower frequency range is least affected by other wireless networks and sources of interference.
  4. Enable the option "Adjust radio channel settings" in the "Radio Channel Settings" section.
  5. Select the wireless channel that was affected the least from the drop-down list "Radio channel".
  6. Click "Apply" to save your settings.
  7. Check whether the issue with your wireless connection still occurs.
    • If the issue with the wireless connection still occurs:
      • Repeat steps 3 - 7 with a wireless channel in the middle and then with one in the higher frequency range. Once you have finished testing, use the wireless channel that was least affected by disturbances.

        Important:The diagram of the wireless environment only reflects the current situation! The allocation of the frequency bands can change significantly over the course of the day because many wireless networks are turned on when in use. Therefore, check several times to see which wireless channels are least affected by interference.

Now the FRITZ!Box is ideally configured and you will achieve the best possible wireless range between your wireless devices and the FRITZ!Box.

Note:If the previous measures did not succeed in sufficiently increasing the wireless range, you can use a FRITZ!WLAN Repeater to extend the FRITZ!Box's wireless network.
