• Connect automatically: To automatically set up a UMTS connection when
data is about to be sent or received, select Automatically. If Manually is se-
lected, you must press the Connect button on the GlobeSurfer 3G each
time a connection is required.
• Inactivity timeout: There is normally no need to change the default value
of 10 minutes. Set it to zero (0) if you don't want the UMTS connection to
disconnect automatically at all. The maximum value is 1440 minutes (24
h). The inactivity timeout is not affected by incoming traffic.
1.5.2 Wireless Setup
The following settings are the most important to set up for the local Wireless
LAN:
• SSID: The Service Set Identifier (SSID) is the name of the specific wire-
less network. Enter a name that you want to use as an identifier of your
specific local wireless network (maximum 32 characters).
• SSID broadcast: When this checkbox is set to Enabled the GlobeSurfer 3G
will broadcast the SSID on your wireless network. This will allow unau-
thorized devices from detecting your SSID and attempting to connect
to your network. De-select the checkbox to disable broadcasting of the
SSID. Disabling SSID broadcast will hide the name of the network from
other wireless devices. This provides a very basic form of security. Other
devices will still be able to connect, provided that they are supplied with
the SSID. A recommendation is to install your wireless network with this
feature enabled and then disable it once you have set up the GlobeSurfer
3G and any wireless clients.
• Encryption: With No encryption selected, anyone with a Wireless PC can
eavesdrop on your network. No encryption should only be used during
installation of your network to simplify the setup procedure. Select WEP
encryption or WPA encryption once your local wireless network has been
set up. See below for instructions on how to set the encryption type.
1.5.2.1 Encryption
The GlobeSurfer 3G supports two types of encryption:
• WEP: Wireless Equivalent Privacy (WEP) is a 64 bit or 128 bit encryption
method with user configurable fixed keys. However, only 40/104 bits are
effectively used.
• WPA: Wi-Fi Protected Access (WPA) is a 256 bit encryption method with
keys that change over time.
Note: WPA provides a higher level of security, provided by its longer key and
dynamic changes made to the key over time. Use WPA with any clients that
support it. If you enable encryption on the GlobeSurfer 3G, you must configure
your wireless PCs to use exactly the same encryption type and keys, otherwise
the devices will not understand each other. The encryption secures the wire-
less communication between GlobeSurfer 3G and its wireless clients. Enabling
