FRITZ!Box 7369 – Service

Wireless connection drops frequently

The wireless connection (WiFi) from a notebook, smartphone, or other wireless device to the FRITZ!Box drops frequently.

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

1 Checking the event log of the FRITZ!Box

  1. Click "System" in the FRITZ!Box user interface.
  2. Click "Event Log" in the "System" menu.
  3. Check whether there are any events that occurred before the error did, or whether only events that occurred after the error are shown.
  4. If events that took place before the error occurred are also shown, proceed with the following section:

2 Installing the latest FRITZ!OS for the FRITZ!Box

3 Installing the latest software for the wireless device

The following step is only necessary if you only experience frequent connection drops with a single wireless device, and other wireless devices used at the same location can establish stable wireless connections to the FRITZ!Box:

  • 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.

If your device's wireless connection still continues to drop, there are unfortunately no further settings in your FRITZ!Box that influence the quality of the wireless connection. In such cases, the problem lies with the wireless device. The manufacturer of the wireless device may be able to give you some troubleshooting tips.

4 Setting the maximum transmitter power

  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. Select "100%" from the drop-down list "Maximum transmitter power". If the drop-down list is not displayed, enable the Advanced View first.
      2. Click "Apply" to save the settings.

5 Finding the ideal location for the FRITZ!Box

  1. If possible, position the FRITZ!Box in a central location.
  2. Do not position the FRITZ!Box directly in the corner of a room.
  3. Position the FRITZ!Box 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 FRITZ!Box as high in the room as possible, for example on a shelf.
  5. Position the FRITZ!Box 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 FRITZ!Box so that it is away from other radio transmitters, for example microwaves, wireless speakers, or Bluetooth devices.

6 Selecting the best wireless channel

  1. Click "Wireless" ("WLAN") in the FRITZ!Box user interface.
  2. Click "Radio Channel" in the "Wireless" ("WLAN") menu.
  3. Click the link "Show disturbances to wireless network" in the "Wireless Environment" section.
  4. Use the diagram to determine which channel in the lower frequency range is least affected by other wireless networks and interference.
  5. Enable the option "Adjust radio channel settings" in the "Radio Channel Settings" section.
  6. From the drop-down list "Radio channel", select the wireless channel that was the least affected.
  7. Click "Apply" to save the settings.
  8. If the issue with your wireless connection still occurs, repeat steps 3 - 7 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 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.

7 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 FRITZ!Box a unique name:

  1. Click "Wireless" ("WLAN") in the FRITZ!Box user interface.
  2. Click "Radio Network" in the "Wireless" ("WLAN") menu.
  3. Enter a unique name without special characters in the field "Name of the wireless radio network (SSID)". 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 to the FRITZ!Box are cleared when you apply the new wireless network name. You must then reconfigure wireless connections to the FRITZ!Box.

Now the FRITZ!Box and the wireless device are ideally configured and the wireless connections between wireless devices and the FRITZ!Box are as stable as possible. If the measures given in this guide do not sufficiently improve the connection, then the wireless environment is causing the issue and cannot be further influenced by the FRITZ!Box.

Note:You can use a FRITZ!WLAN Repeater to quickly and easily extend the range and increase the stability of your wireless network.
