WLAN Radio Network Name (SSID)
FRITZ!Box Fon WLAN 7270 141
 If your WLAN adapter supports neither the WPA nor
the WPA2 mechanism:
– Enable WEP encryption.
– Replace the WLAN key with a new, unique value.
WLAN Radio Network Name (SSID)
In the factory settings of FRITZ!Box, “FRITZ!Box Fon
WLAN 7270” is preset for the SSID (Service Set Identifier).
2.3 Frequency Ranges
WLAN uses the frequency range around 2.4 GHz in the ISM
band. or, alternatively, the frequency range at 5 GHz.
You can use both frequency ranges with the FRITZ!Box.
2.4-GHz Frequency
Band
In the 2.4-GHz frequency band WLAN works in the same
range as Bluetooth, microwave equipment and various
other devices like radio-controlled toys, garage-door
openers and video bridges. This means that interference
may occur within WLANs operated in the vicinity of such
devices. Generally, this has adverse effects on the trans-
mission rate, including aborted connections.
In the 2.4-GHz frequency range the European regulation
authorities have designated 13 channels for WLAN. One
channel has a bandwidth of 20 MHz.
A channel can have a bandwidth of 20 MHz (throughput
up to 130 Mbit/s) or 40 MHz (throughput of up to
300 Mbit/s).
We strongly recommend the use of a WLAN adapter that
supports WPA or WPA2 (for instance, the FRITZ!WLAN USB
Stick N). WEP is out of date and data encrypted with WEP
can be deciphered within minutes.
If an additional device with the same network name is lo-
cated in the vicinity, it can occur that the WLAN adapter
attempts to register there. Therefore you should change
the SSID as soon as possible.
