Radio Channel

Wireless / Radio Channel

The "Radio Channel" page presents an overview of which wireless LAN channels are occupied by wireless networks and displays a list of all of the wireless radio networks at your location. The FRITZ!Box automatically configures the basic radio channel settings. You can adjust these settings as needed.

Click on the "Apply" button to save your settings. If you leave the page without saving, all of your changes will be discarded.

Set radio channel settings automatically (recommended)

With this option the FRITZ!Box automatically checks the wireless environment to select the optimum radio channel settings.

Adjust radio channel settings

With this setting you configure the radio channel settings yourself so that you can adapt them to the circumstances at your location.

  • Wireless standard
    With this setting you specify a wireless standard. The standards are "802.11n+g+b" for the 2.4-GHz band and "802.11n+a" for the 5-GHz band.
  • Radio channel
    If you select the "Auto channel" setting instead of a fixed channel, the FRITZ!Box independently searches the wireless LAN environment for networks in the vicinity and sets the optimum channel. This process can take 30 seconds or more. During this period no wireless device can register at the FRITZ!Box.

2.4-GHz Frequency Band

  • Wireless standard
    With this setting you specify a wireless standard for the 2.4-GHz band. For the 2.4-GHz band these are the standards "802.11n+g", "802.11b+g" and "802.11n+g+b".
  • Radio channel
    If you select the "auto channel" setting instead of a fixed channel, the FRITZ!Box independently searches the wireless LAN environment for networks in the vicinity and sets the optimum channel. This process can take 30 seconds or more. During this period no wireless device can register at the FRITZ!Box.
  • Wireless auto channel including channel 12/13
    If the "Autochannel" option is selected, then all available radio channels will be included in the automatic search. Please note that some wireless devices (like notebooks, for example) may not be able to use the channels 12 and 13 due to erroneous configurations. Establishing a wireless connection to the FRITZ!Box via one of these channels will not be possible in such a case.

5-GHz Frequency Band

  • Wireless standard
    With this setting you specify a wireless standard for the 5-GHz band. For the 5-GHz band that is the standard "802.11n+a".
  • Radio channel
    If you select the "Autochannel" setting instead of a fixed channel, the FRITZ!Box independently searches the wireless LAN environment for networks in the vicinity and sets the optimum channel. This process can take 30 seconds or more. During this period no wireless device can register at the FRITZ!Box.
  • also use wireless LAN channels that may be subject to radar interference

In the default setting the FRITZ!Box uses channels 36 to 48 in the 5-GHz band. Enable this option if the FRITZ!Box should also use channels 52 to 140 in the 5-GHz band.

When using channels 52 to 140, please note that many wireless devices support only channels 36 to 48 so that in some cases no connections to the FRITZ!Box will be possible.

Above channel 52, the FRITZ!Box checks at regular intervals whether the radio channel used is also used by a higher priority radar source, like, for instance, weather radar. If this is the case, the FRITZ!Box automatically switches channels, with the consequence that the wireless device may lose its connection to the FRITZ!Box.

  • Wireless coexistence enabled
    With this option the FRITZ!Box exploits the available channel bandwidth in busy wireless environments to the best possible extent by attempting to use radio channels with a bandwidth of 40 MHz or 80 Hz, respectively.

This means that the FRITZ!Box, depending on which generation of the IEEE 802.11n standard is used, can transport 150 to 450 Mbit/s over wireless LAN. Up to 1300 Mbit/s are possible with the IEEE 802.11ac standard. If not enough space is available in the radio spectrum to allow interference-free transmission on the channel with bandwidth of 40/80 MHz, the FRITZ!Box automatically reduces bandwidths to 20/40 MHz ("fallback") with a correspondingly lower transmission capacity.

  • Maximum transmitter power
    The range of the radio waves can be influenced by adjusting the transmitter power.
  • Optimize wireless LAN transmission for Iive TV applications
    With this option TV transmissions via wireless LAN that are based on the Internet protocol (IP) will have the highest priority during data transmission.

WLAN Location

The "Wireless Location" area displays the allocation of wireless channels by other wireless networks.

  • The allocation of WLAN channels by other wireless networks is separated by frequency bands. Click the "2.4-GHz Band" and "5-GHz Band" tabs to view the allocation of the WLAN channels in these frequency bands.
  • The "Show WLAN disturbances" option displays the graph of which radio channels are already being used by other wireless networks. Overlapping of radio channels can lead to reduced throughput rates, ranges, or even interrupted connections in the participating WLAN radio networks. If your WLAN connection is unstable, look for a better channel in the graph and then select it under "Adjust radio channel settings".

Wireless Radio Networks

The "Wireless Radio Networks" overview shows which wireless radio networks were found at your location.

All radio networks found at your location are displayed in a table indicating their signal strength, radio network name (SSID), the radio channel used, and MAC address.
