Wireless device cannot find FRITZ!Powerline's wireless network

A wireless device (for example a notebook, smartphone, tablet) cannot find FRITZ!Powerline's wireless network (WiFi). It does not display the name of FRITZ!Powerline's wireless network (SSID) when it searches for wireless networks.

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

1 Enabling the wireless network

The following step is only necessary if the "WLAN" LED on FRITZ!Powerline is not lit:

  1. Click "Wireless" ("WLAN") in the FRITZ!Powerline user interface.
  2. Click "Radio Network" in the "Wireless" ("WLAN") menu.
  3. Enable the option "Wireless radio network enabled".
  4. Click "Apply" to save the settings.

2 Enabling the wireless device

Some notebooks have a special switch or a key combination to turn integrated wireless network adapters on and off:

  • Enable the wireless device that you would like to connect to FRITZ!Powerline's wireless network.

    Note:You can find information on how to enable it in the corresponding manual, or consult the device's manufacturer directly.

3 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.

4 Adjusting FRITZ!Powerline's wireless settings


  • Use a network cable to connect a computer to a LAN port on FRITZ!Powerline.

Changing the name of the wireless network (SSID)

Some wireless devices, such as Apple iPhones, cannot connect to wireless routers with certain special characters in their wireless network names. Therefore, remove all special characters from the wireless network name of your FRITZ!Powerline:

  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)".

    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 the settings.

Automatically configuring wireless channel settings

  1. Click "Wireless" ("WLAN") in the user interface of FRITZ!Powerline.
  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 setting.

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 Testing a different wireless device

  • Check whether a different wireless device can find FRITZ!Powerline's wireless network.

If the second wireless device is able to find FRITZ!Powerline's wireless network, then the first wireless device may be defective.
