FRITZ!Repeater 300E Service

Wireless range is too low

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

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.

Note:All instructions on configuration and settings given in this guide refer to the latest FRITZ!OS for the FRITZ!Repeater.

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

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

  1. Install the latest FRITZ!OS on your FRITZ!Repeater.

2 Installing the latest firmware for the wireless router

  1. 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

  1. 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:Refer to the manufacturer for information on how to update, for example consult the manual.
    You can find the latest drivers for the FRITZ!WLAN Sticks in our download area.

4 Finding the ideal location for FRITZ!Repeater and 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 transmitters, for example microwaves, wireless speakers, or Bluetooth devices.
  7. Find the ideal location for the FRITZ!Repeater.

5 Setting the wireless router's transmitter power

Note:For the following instructions, we used a FRITZ!Box as an example. If you are using a different wireless router, refer to the router'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, then the FRITZ!Box is already using its maximum transmitter power.
    • 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.

6 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:For the following instructions, we used a FRITZ!Box as an example. If you are using a different wireless router, refer to the router'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). If only one field is displayed, enable the Advanced View first.
  4. Click "Apply" to save the settings.

All wireless connections are cleared when you apply the new wireless network name. Then you must reconfigure the wireless connection from the FRITZ!Repeater to the FRITZ!Box or to the wireless router as well as the wireless connections to your wireless devices.

7 Selecting the best wireless channel

Note:For the following instructions, we used a FRITZ!Box as an example. If you are using a different wireless router, refer to the router'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. In the "Wireless Environment" section, click on the tab for the wireless frequency band being used (if available).
  4. Click the link "Show disturbances to wireless network" (if available).
  5. Use the diagram "Use of the Wireless LAN Channels" to determine which channel in the lower frequency range is least affected by other wireless networks and 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 the least affected in the wireless frequency band being used.
  8. Click "Apply" to save the settings.
  9. If the issue with your wireless connection still occurs, repeat steps 3 - 8 with a wireless channel in the middle and then with one in the higher frequency range. Then, use the wireless channel with the least interference.

    Important:The diagram of the wireless environment only reflects the current situation! The allocation of the frequency band 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.

8 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.

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

Now the FRITZ!Repeater is ideally configured. 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!Repeater.
