FRITZ!WLAN Repeater N/G Service

Wireless router's Wi-Fi network cannot be found

Your FRITZ!WLAN Stick cannot find the Wi-Fi network of your wireless router (for example FRITZ!Box). When it searches for Wi-Fi networks, the FRITZ!WLAN control software does not display the name of the wireless router (SSID) under "Find and Select WLAN Devices".

Simply proceed as described below. After each measure, check whether the problem is solved.

1 Enabling the Wi-Fi network

The following step is only necessary if you are using a FRITZ!Box as your wireless router, and its "WLAN" LED is not lit:

  1. Briefly push the "WLAN" button on the FRITZ!Box to enable the Wi-Fi network. If you enabled keylock in the FRITZ!Box:
    1. Click "Wireless" ("WLAN") in the FRITZ!Box user interface.
    2. Click "Radio Network" in the "Wireless" ("WLAN") menu.
    3. Enable the Wi-Fi network.
    4. Click "Apply" to save the settings.

2 Optimizing the Wi-Fi settings of the wireless router

Configuring the FRITZ!Box

The following steps are only necessary if you are using a FRITZ!Box as the wireless router:

  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)". This way, the FRITZ!Box evaluates the Wi-Fi 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 Wi-Fi channel settings.
  4. Click "Apply" to save the settings. Now Wi-Fi connections to the FRITZ!Box are briefly cleared and then automatically re-established.
  5. Click "Radio Network" in the "Wireless" ("WLAN") menu.
  6. Enable the option "Name of the wireless radio network visible". This way, all wireless devices can establish a connection to the FRITZ!Box.
  7. Click "Apply" to save the settings.

Configuring the wireless router

The following steps are only necessary if you are using a wireless router from another manufacturer:

Note:Information on how to set up the wireless router can be obtained from its manufacturer, for example refer to the manual.

  1. Enable the 2.4 GHz frequency band on your wireless router.
  2. In the wireless router, configure channels with as little interference as possible. If you can configure the wireless router so that it automatically selects the best Wi-Fi channel settings, enable this option.
  3. Configure the wireless router so that its Wi-Fi is transmitted at full power.
  4. Enable the display of Wi-Fi network names (SSID) and give the router a unique Wi-Fi network name. This way, all wireless devices can establish a connection to the FRITZ!Box and prevents your wireless devices from trying to connect to the wrong wireless router if there are wireless networks with the same name in the area.

    Note:All Wi-Fi connections are cleared when you change the Wi-Fi network name. You must then reconfigure the Wi-Fi connections.

3 Updating FRITZ!OS and Wi-Fi software

Updates contain improvements, bug fixes, and new functions. Therefore, install the latest FRITZ!OS or software version on all of the devices:

Installing the latest software for the wireless router

  1. Install the latest software for your wireless router according to the manufacturer's instructions. If you are using a FRITZ!Box as a wireless repeater, proceed as described in the guide Updating FRITZ!OS.

Installing the latest driver for the FRITZ!WLAN Stick

  1. Download the latest driver for your FRITZ!WLAN Stick from our FTP server https://ftp.avm.de/archive/cardware/fritzwlanusb.stick/.
  2. Double-click the file "avm_fritz!wlan_usb_stick [...].exe" and follow the instructions.

4 Removing USB 3.0 devices

  1. For testing purposes, remove all USB 3.0 devices from the USB ports on the wireless router and the computer to which the FRITZ!WLAN Stick is connected.
  2. If the problem no longer occurs, a USB device was affecting the Wi-Fi connection and you must reduce the interference caused by the USB device.

5 Finding the ideal location for the wireless router

  1. If possible, place the wireless router in a central location.
  2. Do not place the wireless router directly in the corner of a room.
  3. Position the wireless router 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 wireless router as high in the room as possible, for example on a shelf.
  5. Place the wireless router so that there are as few obstacles as possible between it and other wireless devices. Especially metallic objects or objects containing water, such as radiators, refrigerators, or even houseplants, significantly reduce the quality of the wireless signal.
  6. Place the wireless router away from other radio transmitters, for example microwaves, wireless speakers, or Bluetooth devices.

6 Testing a different wireless device

  1. Test whether a different wireless device can find the wireless router's Wi-Fi network.
    • If the other wireless device can find the wireless router's Wi-Fi network, the FRITZ!WLAN Stick may be defective.
