of the FRITZ!Box (see also: Sharing a USB Printer on
page 103).
• You can connect a USB hub to the FRITZ!Box and use up
to four USB devices at this hub.
You can use USB hubs with or without a separate power
supply. We recommend deploying a USB hub with its
own power supply if the USB devices to be connected ex-
ceed a total current consumption of 500 mA (see also:
Power Supply for USB Devices on page 100).
• You can connect a USB modem. With a USB modem the
FRITZ!WLAN USB Stick can establish the Internet connec-
tion via the mobile communications network (UMTS/HS-
PA) (see also: Configuring an Internet Connection for the
Mobile Network on page 33).
• You can connect a USB stick from the FRITZ!WLAN USB
Stick series by AVM to conveniently establish secure
wireless LAN connections using AVM Stick & Surf (see:
Establishing a Wireless Connection with AVM Stick &
Surf on page 22).
15.3 Using USB Devices Safely
Follow the instructions below about how to use USB devices
on your FRITZ!Box.
• The FRITZ!Box can not defend the USB memory from ex-
ternal influences. This means that voltage spikes or
drops, like those that occur during electrical storms, may
lead to data losses on connected USB storage media. We
recommend making regular backups of the USB memory
contents to avoid any losses.
• Whenever you want to remove USB devices from the
FRITZ!Box, go to the “Home Network / USB Devices” area
in the FRITZ!Box user interface to remove them safely
and avoid any loss of data.
