FRITZ!WLAN Repeater 450E – Service

Wireless connection to FRITZ!WLAN Repeater drops frequently

The wireless connection (WiFi) from the FRITZ!WLAN Repeater to the wireless router (for example a FRITZ!Box) and/or the wireless connection from a notebook, smartphone, or another wireless device to the FRITZ!WLAN Repeater drops frequently.

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

1 Wait for upcoming FRITZ!OS

This section only applies if FRITZ!WLAN Repeater is connected to the router over a LAN connection and the error occurs since updating FRITZ!OS.

We are currently working on a solution and shall correct this behavior with a FRITZ!OS update for the FRITZ!WLAN Repeater as soon as possible. We cannot give you an exact release date for the update yet. 

Note:You can have the push service notify you by e-mail when new updates are available. This option can be enabled in the user interface under "System > Push Service".

Workaround

You can install a beta version until a new FRITZ!OS update has been released; this issue has been resolved in this beta version:

  1. Call up https://service.avm.de/downloads/ in a web browser, switch to the folder "Beta", and then switch to the subfolder for your FRITZ!WLAN Repeater model.
  2. Download the beta version for your FRITZ!WLAN Repeater model to the computer.
  3. Unzip the zip file to your computer (for example to the Desktop).
  4. Install the beta version (image file) as described in the infobeta.txt file.

    Note:You can reinstall the regular FRITZ!OS for your FRITZ!WLAN Repeater at any time. The infobeta.txt file contains instructions on the procedure.

2 Enabling or refreshing the auto channel

If the auto channel is enabled, the FRITZ!WLAN Repeater 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 repeater 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!WLAN Repeater are cleared and then automatically re-established when you enable or refresh the auto channel.

  1. Click "Wireless" ("WLAN") in the user interface of the FRITZ!WLAN Repeater.
  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.

3 Correcting the wireless router's wireless encryption method

If you are using a wireless router other than the FRITZ!Box, then the connection may drop if it does not fully support the repeater's encryption method. In the factory settings, the FRITZ!WLAN Repeater supports the secure encryption methods WPA2 and WPA (Wi-Fi Protected Access) at the same time. Make sure that your wireless router is set for one of these encryption methods:

  • Enable the encryption method WPA2 (CCMP) or WPA (TKIP) in the wireless router's settings.

4 Updating wireless devices

New firmware and driver versions contain bug fixes as well as optimizations. Therefore, make sure that all of the devices are using the latest software version:

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

Installing the latest FRITZ!OS for the FRITZ!Box

Installing the latest firmware for the wireless router

  • Install the latest firmware on your router.

    Note:You can find information on updating the router in its manual, or consult the manufacturer directly.

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.

5 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 repeater

  1. Click "Wireless" ("WLAN") in the user interface of the FRITZ!WLAN Repeater.
  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".
      2. Select "100%" from the drop-down list "Maximum transmitter power".
      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 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. Since not all wireless devices support all special characters, we recommend using only standard Latin letters (not letters such as ä, ë, ö, ü, á, é, í) and numbers.
  4. Click "Apply" to save the 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.

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 finding a different location for the device, the wireless router, or the FRITZ!WLAN Repeater.

8 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.
