FRITZ!Box 7581 Service - Knowledge Base
Slow wireless connection according to 802.11g/b
The data rate of a wireless connection (WiFi) according to the wireless standard 802.11g or 802.11b is lower than allowed by the wireless standard.
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 Installing the latest FRITZ!OS for the FRITZ!Box
- Install the latest FRITZ!OS on the FRITZ!Box.
2 Installing the latest software for the wireless device
- Install the latest driver for the computer's wireless network adapter (for example using Windows Update) or the latest operating system (for example Android, iOS) for the wireless device.
Note:Information on the update can be obtained from the device's manufacturer, for example refer to the manual. You can find the latest drivers for the FRITZ!WLAN Sticks in our download area.
3 Automatically configuring wireless channel settings
Configure the following settings so that the FRITZ!Box checks the wireless environment at regular intervals 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.
4 Finding the ideal location for the FRITZ!Box
- If possible, place the FRITZ!Box in a central location. FRITZ!Box has omnidirectional antennas. The wireless signal is therefore emitted spherically in all directions.
- Do not place the FRITZ!Box directly in the corner of a room.
- Place 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.
- Place the FRITZ!Box as high in the room as possible, for example on a shelf.
- Place 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.
- Place the FRITZ!Box away from other radio transmitters, for example microwaves, wireless speakers, or Bluetooth devices.
5 Removing USB 3.0 devices
- For testing purposes, remove all USB 3.0 devices from the FRITZ!Box's USB ports.
- If the problem no longer occurs, a USB device was affecting the wireless connection. Eliminate the interference caused by the USB device.
6 Disabling Bluetooth for testing purposes
Bluetooth influences the wireless speed in the 2.4 GHz frequency band, which is particularly noticeable when using real-time applications such as video streaming:
- Disable Bluetooth on the wireless device (for example smartphone, tablet).
7 Using a wireless device that supports 802.11n or 802.11ac
- Use a wireless device that supports the wireless standard 802.11n or 802.11ac to establish the wireless connection. With these standards you can achieve wireless user data rates that are significantly higher.
Note:Information on the range of functions can be obtained from the manufacturer, for example refer to the manual.
All current FRITZ!WLAN Sticks support 802.11n.
FRITZ!WLAN Stick AC 430 and AC 860 also support 802.11ac.
