FRITZ!WLAN Repeater N/G Service

Wireless connection drops frequently

The wireless connection (WiFi) between a FRITZ!WLAN Stick and a wireless router (for example a FRITZ!Box) drops frequently.

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

1 Installing the latest firmware for the wireless router

  • Install the latest firmware for your wireless router according to the manufacturer's instructions.

    Note:If you are using a FRITZ!Box, install the latest FRITZ!OS as described in this guide.

2 Installing the latest driver for the FRITZ!WLAN Stick

3 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, then a USB device was affecting the wireless connection and you must reduce the interference caused by the USB device.

4 Setting the maximum transmitter power

Setting the wireless router's transmitter power

Note:We used a FRITZ!Box as an example for the configuration. If you are using a different wireless router, refer to the device's manufacturer for information on how to set it up, for example consult the manual.

  1. Click "Wireless" ("WLAN") in the FRITZ!Box user interface.
  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" (if available).
      2. Select "100%" from the drop-down list "Maximum transmitter power". If the drop-down list is not displayed, enable the Advanced View first.
      3. Click "Apply" to save the settings.

Setting transmitter power of the FRITZ!WLAN Stick

The following step is only necessary if you are using the FRITZ!WLAN control software:

  1. Double-click the FRITZ!WLAN symbol in the notification area of the Windows taskbar (Systray).
  2. Click "Cancel" in the "Find and Select WLAN Devices" window.
  3. Right-click the FRITZ!WLAN Stick symbol.
  4. Enable the option "Expert Mode" in the "WLAN Device Properties" window.
  5. Change the transmitter power to "100".
  6. Click "OK" to save the settings.

5 Enabling or refreshing the auto channel

When the auto channel is enabled, the FRITZ!Box checks the wireless environment and automatically selects the most suitable wireless channel settings. The allocation of the frequency band can change significantly over the course of the day, though. The FRITZ!Box does not refresh the auto channel as long as wireless devices are still connected with it. However, you can manually refresh the auto channel at any time:

  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)".
  4. Click "Apply" to save the settings.

    Note:When you enable or refresh the auto channel, all wireless connections to the FRITZ!Box are cleared and automatically re-established.

  5. Click the "Refresh Auto Channel" button.

6 Finding the ideal location for the wireless router

  1. If possible, position the wireless router in a central location.
  2. Do not position 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. Position the wireless router as high in the room as possible, for example on a shelf.
  5. Position 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, for example radiators, refrigerators, or even houseplants, significantly reduce the quality of the wireless signal.
  6. Position the wireless router away from other radio transmitters, for example microwaves, wireless speakers, or Bluetooth devices.

7 Connecting the FRITZ!WLAN Stick without a USB hub

The following step is only necessary if you connected the FRITZ!WLAN Stick to a USB hub instead of connecting it directly to the USB port on your computer:

Note:The FRITZ!WLAN Stick can be used with many USB hubs that support at least USB 1.1. However, AVM cannot guarantee that USB hubs will work properly.

  1. Remove the USB hub from the computer for testing purposes.
  2. Connect the FRITZ!WLAN Stick directly to the USB port on your computer.

8 Installing the latest chipset drivers for your mainboard

  • Install the latest drivers for the mainboard chipset on your computer (the chipset is a part of the mainboard that computer components are attached or connected to).

    Note:You can find the latest drivers in the download area of the mainboard or chipset manufacturer's website.

9 Changing the name of the wireless network (SSID)

If there are other wireless networks with the same name in the immediate vicinity, wireless devices may automatically attempt to connect to the wrong wireless network. To avoid this, give your wireless router a unique name:

Note:We used a FRITZ!Box as an example for the configuration. If you are using a different wireless router, refer to the device's manufacturer for information on how to set it up, for example consult the manual.

  1. Click "Wireless" ("WLAN") in the FRITZ!Box user interface.
  2. Click "Radio Network" in the "Wireless" ("WLAN") menu.
  3. In the field "Name of the wireless radio network (SSID)", enter a unique name for the 2.4 GHz and the 5 GHz frequency band (if applicable) without special characters. If only one field is displayed, enable the Advanced View first. Since not every wireless device support all special characters, we recommend using only standard alphanumeric characters and not symbols or special letters such as ä, ë, ö, ü, á, é, í.
  4. Click "Apply" to save the settings.

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

Now the FRITZ!WLAN Stick and the wireless router are ideally configured and the wireless connections between wireless devices and the wireless router are as stable as possible. If the measures given in this guide do not sufficiently improve the connection, then the wireless environment is causing the issue and cannot be further influenced by the FRITZ!WLAN Stick or wireless router.

Note:You can use a FRITZ!WLAN Repeater to quickly and easily extend the range and increase the stability of your wireless network.
