Wireless connection between FRITZ!Powerline and a wireless device drops frequently

The wireless connection between a notebook, smartphone, or other wireless device and FRITZ!Powerline drops frequently.

Cause

  • The quality of the wireless connection is influenced by surrounding structural conditions (for example thickness and reinforcement of the walls), the wireless device being used, and also by other electronic devices in the vicinity such as microwaves, baby monitors, wireless speakers, and Bluetooth devices.

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 Wait for upcoming FRITZ!OS

This section only applies if FRITZ!Powerline is connected to the router using the wiring in your home or over a LAN connection and the error occurs since updating FRITZ!OS.

We are currently working on a solution and shall correct this behavior with a FRITZ!OS update for FRITZ!Powerline as soon as possible. We cannot give you an exact release date for the update yet.

Note:You can have the push service notify you by e-mail when new updates are available. This option can be enabled in the user interface under "System > Push Service".

Workaround

You can install a beta version until a new FRITZ!OS update has been released; this issue has been resolved in this beta version:

  1. Call up https://service.avm.de/downloads/beta/ in a web browser and switch to the folder for your FRITZ!Powerline.
  2. Download the beta version for your FRITZ!Powerline model to the computer.
  3. Unzip the ZIP file to your computer (for example to the Desktop).
  4. Install the beta version (image file) as described in the infobeta.txt file.

    Note:You can reinstall the regular FRITZ!OS for your FRITZ!Powerline at any time. The infobeta.txt file contains instructions on the procedure.

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 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.

4 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.

5 Finding the ideal location for wireless devices

  • Do not position FRITZ!Powerline directly in the corner of a room.
  • 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.
  • 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.
  • Position FRITZ!Powerline so that it is away from other transmitters (for example microwaves, baby monitors, wireless speakers, Bluetooth devices).
  • 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.

6 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.
