FRITZ!WLAN Repeater N/G Service

Wireless range is too low

The range of the wireless connection (WiFi) between your FRITZ!WLAN Stick and wireless router (for example a FRITZ!Box) is too low. Even at a short distance from the wireless router, web pages load slowly, it takes a long time to download files, and video streams are not played correctly.

Cause

  • Surrounding structural conditions (such as thickness and reinforcement of the walls) as well as other electronic devices such as wireless speakers and baby monitors influence the quality and thus the range of the wireless connection.

Simply proceed as described below. After each measure, check whether the problem 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 Removing USB 3.0 devices

  • 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.

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 the transmitter power of the FRITZ!WLAN Stick

  1. Double-click the FRITZ!WLAN icon in the notification area of the Windows taskbar (Systray).
  2. Click "Properties" in the "Connection Monitor" window.
  3. Select "100%" from the drop-down list "Transmitter power in %" under "Properties".
  4. Click "Close" to save the settings.

5 Identifying sources of interference

  1. Turn off all devices that could interfere with the wireless network.

    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. Check whether the wireless connection is still impaired.
    • If the wireless connection is no longer impaired:
      1. Turn the devices on again, one after the other.
      2. Each time you turn on a device, check whether the wireless connection is impaired again.
        • Once you have identified a device that causes interference, you have the following options:
          • Leave the devices that cause interference turned off,
            • or:
          • Enable or refresh the auto channel (see the section "Enabling or refreshing the auto channel"),
            • or:
          • Find the ideal location for the wireless router (see the section "Finding the ideal location for wireless devices").

6 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.

7 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.

8 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.

9 Establishing a wireless connection to the 5 GHz frequency band

Some wireless routers provide a wireless network in the 2.4 GHz and the 5 GHz frequency band. The 5 GHz frequency band is less affected by interference. Therefore, switch to this frequency band if your wireless devices support the 5 GHz frequency band:

Note:Not all wireless devices support the 5 GHz frequency band.
FRITZ!WLAN Stick AC 430, FRITZ!WLAN Stick AC 860, and FRITZ!WLAN Stick N (v2) support the 5 GHz frequency band.

  • Use the 5 GHz frequency band to establish the wireless connection to the router.

Now the FRITZ!WLAN Stick and the wireless router are ideally configured and you will achieve the greatest possible wireless range between them. If the wireless range is still too low despite these measures, 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.
