FRITZ!Powerline 540E Service

Wireless range is low

The range of the wireless connection (WiFi) between FRITZ!Powerline and a wireless device (for example a notebook, smartphone, tablet) 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  • Wireless devices with software (for example drivers, firmware) that is out of date, sources of interference in the vicinity, structural conditions (for example thickness and reinforcement of the walls), as well as other devices that emit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 FRITZ!Powerline.

Simply proceed as described below. After each measure, check whether the issue persists.

1 Installing the latest FRITZ!OS for FRITZ!Powerline

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 user interface of FRITZ!Powerline.
  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

If the auto channel is enabled, FRITZ!Powerline checks the wireless environment and automatically selects the optimum wireless channel settings. However, the allocation of the frequency bands can change significantly over the course of the day. FRITZ!Powerline does not refresh the auto channel as long as wireless devices are still connected with the adapter. You can therefore manually refresh the auto channel at any time:

Note:All wireless connections to FRITZ!Powerline are cleared and then automatically re-established when you enable or refresh the auto channel.

  1. Click "Wireless" ("WLAN") in the FRITZ!Powerline 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.
  5. Click the "Refresh Auto Channel" button.

5 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 to FRITZ!Powerline 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 finding a different location for the device or the FRITZ!Powerline adapter.

6 Finding the ideal location for wireless devices

  1. Do not position FRITZ!Powerline directly in the corner of a room.
  2. Position FRITZ!Powerline 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.
  3. Position the FRITZ!Powerline adapter 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.
  4. Position FRITZ!Powerline so that it is away from other transmitters (for example microwaves, baby monitors, wireless speakers, Bluetooth devices).
  5. For testing purposes, position FRITZ!Powerline 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.

7 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!Powerline a unique name:

  1. Click "Wireless" ("WLAN") in the user interface of FRITZ!Powerline.
  2. Click "Radio Network" in the "Wireless" ("WLAN") menu.
  3. Enter a name of your choice that does not contain special characters for the "Name of the wireless radio network (SSID)". Since not all wireless devices support all special characters, we recommend using only standard Latin letters (not letters such as ä, ë, ö, ü, á, é, í) and numbers.
  4. Click "Apply" to save the settings.

All wireless connections are cleared when you apply the new wireless network name. You must then reconfigure the wireless connections to FRITZ!Powerline.

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

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