FRITZ!WLAN Stick v2 Service

Wireless range is low

The range of the wireless connection (WiFi) between your FRITZ!WLAN Stick and wireless router (for example a FRITZ!Box) is low.


  • An out of date driver for the FRITZ!WLAN Stick, sources of interference in the vicinity, structural conditions (for example thickness and reinforcement of the walls), as well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.

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

1 Installing the latest driver for the FRITZ!WLAN Stick

2 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.

3 Setting the maximum transmitter power

Setting the wireless router's transmitter power

+Note:We used a FRITZ!Box as an example for configuration. Some FRITZ!Box settings are only displayed if the advanced view is enabled. Refer to the respective manufacturer for information on how to set up other routers, 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. Check which wireless channel setting is enabled.
    • 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".
      3. Click "Apply" to save your settings.

Setting the 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 icon 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 icon.
  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.

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 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 setting the channel manually.

5 Finding the ideal location for wireless devices

  • If possible, position the wireless router in a room that is centrally located.
  • Do not position the wireless router directly in the corner of a room.
  • 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.
  • Position the wireless router as high in the room as possible, for example on a shelf.
  • Position the wireless router 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 the wireless router so that it is away from other transmitters (for example microwaves, baby monitors, wireless speakers, Bluetooth devices).
  • For testing purposes, position the wireless router and the computer with the FRITZ!WLAN Stick 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 wireless router a unique name:

Note:We used a FRITZ!Box as an example for configuration. You can find information on configuring a different router in its manual, or consult the manufacturer directly.

  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 name of your choice for the frequency band you are using that does not contain special characters.

    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.

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

7 Selecting the best wireless channel

Note:We used a FRITZ!Box as an example for configuration. You can find information on configuring a different router in its manual, or consult the manufacturer directly.

  1. Click "Wireless" ("WLAN") in the FRITZ!Box user interface.
  2. Click "Radio Channel" in the "Wireless" ("WLAN") menu.
  3. In the "Wireless Environment" section, click on the tab for the wireless frequency band being used (if available).
  4. Click on the link "Show disturbances to wireless network" (if available).
  5. Use the graph to determine which channel in the lower frequency range is least affected by other wireless networks and sources of interference.
  6. Enable the option "Adjust radio channel settings" in the "Radio Channel Settings" section.
  7. From the drop-down list "Radio channel", select the channel that was affected the least in the wireless frequency band being used.
  8. Click "Apply" to save the settings.
  9. Check whether the issue with your wireless connection still occurs.
    • If the issue with the wireless connection still occurs:
      • Repeat steps 3 - 9 with a wireless channel in the middle and then with one in the higher frequency range. Once you have finished testing, use the wireless channel that was least affected by disturbances.

        Important:The diagram of the wireless environment only reflects the current situation! The allocation of the frequency bands can change significantly over the course of the day because many wireless networks are turned on when in use. Therefore, check several times to see which wireless channels are least affected by interference.

Now the FRITZ!Box and the FRITZ!WLAN Stick are ideally configured and you will achieve the best possible wireless range between them.

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