FRITZ!WLAN Repeater N/G 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.

Cause

  • An out of date driver for the FRITZ!WLAN Stick, sources of interference in the vicinity, structural conditions (for example thickness and reinforcement of the walls), as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

If the auto channel is enabled, the FRITZ!Box 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. The FRITZ!Box does not refresh the auto channel as long as wireless devices are still connected with it. You can therefore manually refresh the auto channel at any time:

Note:All wireless connections to the FRITZ!Box are cleared and then automatically re-established when you enable or refresh the auto channel.

  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.
  5. Click the "Refresh Auto Channel" button.

5 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 finding a different location for the device or the wireless router.

6 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.

7 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 unique name for the 2.4 GHz and the 5 GHz frequency band (if applicable) that does not contain special characters.
  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!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.
