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 these settings 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.
• Frequency band
  The FRITZ!Box transmits in the 2.4-GHz (ISM) 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.
• Wireless auto channel including channel 12/13
  If the "auto channel" 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.
• Use optimized radio channels When this option is enabled, FRITZ!Box attempts to use radio channels with a bandwidth of 40 MHz. This means that the FRITZ!Box, depending on which generation of the IEEE 802.11n standard is used, can transport 300 to 450 Mbit/s over wireless LAN. If not enough space is available in the radio spectrum to allow interference-free transmission on the channel with bandwidth of 40 MHz, the FRITZ!Box automatically reduces bandwidths to 20 MHz ("fallback") with a correspondingly lower transmission capacity.
• not in high-use wireless LAN environments With this option the FRITZ!Box is directed not to use channels with 40-MHz channel bandwidth in wireless LAN environments subject to heavy use, like cities. This option allows the FRITZ!Box to achieve robust data transfer and coexist with many other wireless radio networks with as little interference as possible (recommended). You can disable this option in seldom used wireless LAN environments to ensure maximum transfer rates, yet this change can be make data transfer less robust and stable (not recommended).
• Automatically reduce transmitter power to the level actually needed If this option is enabled, the FRITZ!Box independently reduces the transmitter power to the necessary value when the quality of the wireless LAN connection is good. This serves to reduce radiation emissions.
• Maximum transmitter power The range of the radio waves can be influenced by adjusting the transmitter power.
• Optimize wireless LAN transmission for IPTV 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.

Adjust radio channel settings

With these settings 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.
• Frequency band
  FRITZ!Box transmits in either the 2.4-GHz (ISM) band or in the 5-GHz band, but not simultaneously in both bands. Due to the multitude of users (WiFi, Bluetooth, microwave devices etc.), the 2.4-GHz band is loaded more than the 5-GHz band.

  Note: If the FRITZ!Box detects the presence of a so-called "higher-priority user" in the 5-GHz band, such as radar, for instance, it automatically switches channels.

• 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.

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".
