FRITZ!WLAN Repeater N/G Service

Wireless range is low

The range of the wireless connection (WiFi) between your FRITZ!WLAN Repeater and wireless router (for example a FRITZ!Box) and / or wireless device (for example a notebook, smartphone, tablet) is low.

Cause

  • Wireless devices with software (for example drivers, firmware) that is out of date, sources of interference in the vicinity, structural conditions (for example thickness and reinforcement of the walls), as well as other devices that emit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.

Note:The configuration procedure and notes on functions given in this guide refer to the latest firmware for the FRITZ!WLAN Repeater.

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

1 Installing the latest FRITZ!OS for the FRITZ!WLAN Repeater

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 Installing the latest software for the wireless device

  • Install the latest driver for your computer's wireless network adapter or the latest operating system (for example Android, iOS) for the wireless device.

    Note:You can find information on updating the wireless network adapter or wireless device in its manual, or consult the manufacturer directly.
    You can find the latest drivers for the FRITZ!WLAN Sticks in our download area.

4 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. 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. 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 repeater

  1. Click "Wireless" ("WLAN") in the user interface of the FRITZ!WLAN Repeater.
  2. Click "Radio Settings" in the "Wireless" ("WLAN") menu.
  3. Select "100%" from the drop-down list "Maximum transmitter power".
  4. Click "Apply" to save the settings.

5 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 your settings.

All wireless connections are cleared when you apply the new wireless network name. You must then reconfigure the wireless connection from the FRITZ!WLAN Repeater to the wireless router as well as the wireless connections to your other devices.

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).
  • Find the ideal location for the repeater.

7 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 each individual device, check whether the wireless connection to the repeater 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.

8 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 "Use of the Wireless LAN Channels" 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 your 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.

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 subject to interference less frequently. 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 Repeater is ideally configured and you will achieve the best possible wireless range between your wireless devices and the FRITZ!WLAN Repeater.
