Wireless connection drops frequently
The wireless connection (WiFi) from a notebook, smartphone, or other wireless device to the FRITZ!Box drops frequently.
Note:All instructions on configuration and settings given in this guide refer to the latest FRITZ!OS for the FRITZ!Box.
Simply proceed as described below. After each measure, check whether the problem persists.
1 Checking the event log of the FRITZ!Box
- Click "System" in the FRITZ!Box user interface.
- Click "Event Log" in the "System" menu.
- Check whether there are any events that occurred before the error did, or whether only events that occurred after the error are shown.
- If events that took place before the error occurred are also shown, proceed with the following section:
- If only events that took place after the error are shown, follow the instructions in our guide FRITZ!Box restarts occasionally.
2 Installing the latest FRITZ!OS for the FRITZ!Box
- Install the latest FRITZ!OS on 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 the 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 Automatically configuring wireless channel settings
Configure the following settings so that the FRITZ!Box checks the wireless environment on a regular basis and automatically selects the best wireless channel settings.
- Click "Wireless" ("WLAN") in the FRITZ!Box user interface.
- Click "Radio Channel" in the "Wireless" ("WLAN") menu.
- Enable the option "Set radio channel settings automatically (recommended)".
- Click "Apply" to save the settings. Now wireless connections to the FRITZ!Box are briefly cleared and then automatically reestablished.
5 Finding the ideal location for the FRITZ!Box
- If possible, position the FRITZ!Box in a central location. FRITZ!Box has omnidirectional antennas. The wireless signal is therefore emitted spherically in all directions.
- Do not position the FRITZ!Box directly in the corner of a room.
- 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.
- Position the FRITZ!Box as high in the room as possible, for example on a shelf.
- Position the FRITZ!Box so that there are as few obstacles as possible between it and the wireless devices. Even small objects in the immediate vicinity of your FRITZ!Box can greatly reduce the coverage area of the wireless signal. Metallic objects or objects containing water, for example radiators, refrigerators, or even houseplants, significantly reduce the quality of the wireless signal.
- Position the FRITZ!Box away from other radio transmitters, for example microwaves, wireless speakers, or Bluetooth devices.
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.
Note:If the measures given in this guide do not sufficiently improve the connection, you can use a FRITZ!WLAN Repeater to extend the range and increase the stability of your wireless network.
