Introduction: Dell™ TrueMobile™ 1400 WLAN Card User's Guide
Before you begin
Things you should know
TrueMobile 1400 network
Before you begin
Obtain the following information from your network administrator (if you are a home user, obtain this information from the person that
installed your wireless access point):
●
●
●
●
●
Network names (SSID) of the specific wireless networks that you want to connect to.
WEP (Wired Equivalent Privacy) key information (if any) for the networks you want to connect to.
For Microsoft® Windows® networking, your customer name and workgroup name.
For your network account, your user name and password.
Your IP address (if not using a DHCP server)
Things you should know
When you start your computer, your Dell™ TrueMobile™ 1400 WLAN card detects certain wireless networks that are within range. Before
you can connect to these and other wireless networks, you must configure a profile for each network using the information you obtained
from your network administrator. Instructions for configuring a network profile are provided in Completing the setup.
WEP is a security protocol for wireless local area networks (defined in the IEEE 802.11b standard) that encrypts data sent over radio
waves. The use of the WEP key is optional and can be enabled or disabled. If the network you are connecting to has enabled WEP, you
must also enable WEP in the network profile and set the WEP key to match the WEP key used by the network. Otherwise, you cannot
connect to the network.
Dell TrueMobile 1400 network
The Dell TrueMobile 1400 solution allows you to make a wireless connection to a network, as illustrated below.

Setting up an ad hoc (peer-to-peer) group network for connecting to the
Internet
To connect the computers in an ad hoc group network to the Internet, you must install the Windows Internet connection sharing (ICS)
component. ICS installation is not required, however, for communication among a group of computers that have a Dell TrueMobile
1400 Internal Dual-band WLAN Card installed in each computer. You must also add an ad hoc network to the Preferred networks
list on the Wireless Networks tab of the Network Properties box (see Opening the TrueMobile 1400 Client Utility).
Select one of your desktop computers to serve as the host computer (all other computers are called clients). The host computer must
be running either the Windows 2000 or Windows XP operating system. The host computer is the only computer that connects directly
to the Internet. Dell recommends that the host computer be the desktop computer having the fastest microprocessor and the most
memory.

NOTES
1—The range of your wireless devices can be affected when the antennas are placed near metal surfaces and solid high-density
materials.
2—Range is also affected by obstacles in the signal path (of the radio) that may either absorb or reflect the radio signal.
3—In open office environments, the absence of physical obstructions between antennas improves the range because there is a clear
line-of-sight.
4—A semi-open office environment is one in which the work area is divided by short walls that are above the level of the desk top;
antennas are at desk top level.
5—A closed office environment is one in which the work areas are separated by floor-to-ceiling walls.

Cannot connect to the network
If your Dell TrueMobile 1400 Internal Dual-band WLAN Card appears to be functioning properly but you cannot connect to the
network, the problem may be that there is a mismatch between the Network name (SSID) and Wireless network key (WEP)
settings in your Wireless Network Properties and the name and WEP key of the network you are trying to connect to. As explained in
Completing the setup, the network name and WEP key are case sensitive. Verify that the spelling and case of these parameters are
correct and that the settings are exactly the same on all computers on the network.
If you have verified that the spelling and case of these parameters are correct and that the settings are exactly the same on all
computers on the network and you are still unable to connect to the network, see Performance and connectivity problems.

Data transfer is sometimes
very slow.
Microwave ovens and some cordless phones operate at the same radio frequency as the Dell
TrueMobile 1400 Internal Dual-band Cards. When the microwave oven or cordless phone is in
use, it interferes with the wireless network. Therefore, keep computers having the Dell
TrueMobile 1400 Internal Dual-band Cards at least 20 feet away from your microwave oven
and any cordless telephone that operates at a frequency of 2.4 GHz.
Data transfer is always very
slow.
Some homes and most offices are steel-framed structures. The steel in such buildings may
interfere with your network's radio signals, thus causing a slowdown in the data transmission rate.
Try moving your computers to different locations in the building to see if performance improves.
Computers are not
communicating with the
network.
If your network has an AP1100 access point, check all cables and make sure the power LED on
the front of the AP1100 is green.
In Microsoft® Windows® 2000,
I get the following error
message: Medium cable
disconnected. Also, there is a
red X on my network icon in
the system tray.
This indicates that your computer is not properly configured to connect to the network. Verify that
all of the wireless network properties settings are correct (see Viewing or modifying the wireless
network properties). Also, make sure that your computer is receiving a good signal from the
access point. See Viewing the link status of your wireless connection.
Network performance is really
slow when the system is
docked to a docking station
that has an active Ethernet
port. NOTE—For Windows
2000 only.
This condition occurs if you dock your system into a docking station that has an active Ethernet
port while your Dell TrueMobile 1180 internal Mini PCI card is still active and connected to an
access point. This happens because Windows 2000 must now handle two active network
connections. You need to either disconnect the Ethernet cable from your docking station, or
disable the radio on your Mini PCI Card. To disable the radio on your Mini PCI Card, right click on
the Dell TrueMobile 1180 utility icon icon in the system tray and click Disable Radio. NOTE—The
radio is not automatically enabled when you computer next starts. To enable the radio, right-click
on the Dell TrueMobile 1180 wireless utility icon and click Enable Radio.

Tämä laite vastaa EU:n radio- ja telepäätelaitedirektiivin (EU R&TTE Directive 1999/5/EC) vaatimuksia.
This product is intended to be used in all countries of the European Economic Area when operating in IEEE 802.11b
mode at 2.4 GHz (see France below). When operating in the IEEE 802.11a mode at 5 GHz, however, the product is
restricted further. Refer to Dell's Web site (www.dell.com) for full information.
France
Some areas of France have a restricted frequency band for operation in the IEEE 802.11b mode at 2.4 GHz. The
following information describes this restriction (please check ART's Web site (http://www.art-telecom.fr) for more up-todate information).
Autorité de régulation des télecommunications (ART) has made decisions that will allow users to install WLAN ( wireless
LAN) systems to provide high-speed Internet services primarily in high-traffic areas (called hot spots). ART recently
released guidelines that establish the conditions for experimenting with the installation of public WLANs, such as for highspeed Internet access in locations that are currently being poorly served by existing networks. Such public WLANs would
operate in the 2.4 GHz frequency band. This series of measures answers many of the concerns expressed during ART's
public consultation on this topic.
Decisions allowing the installation of wireless terminals in hot spots (train stations, airports, business centers, and the
like): In agreement with the Ministry of Defence, ART has made two decisions setting the conditions for using wireless
LANs in the 2.4 GHz band. One of these decisions has been submitted to the Minister of Telecommunications for
approval. These decisions will allow the installation of WLAN access points to provide public services in high-traffic public
places. This will allow service providers and licensed operators to install access points using 2.4 GHz band technologies
without authorisation, under the following technical conditions:
1. In 38 départements (see Metropolitan départements for listing):
●
●
The 2400–2454 MHz band can be used both indoors and outdoors using systems (access points and devices)
with less than 300 milliwatts (mW) of power.
The 2454–2483.5 MHz band can be used indoors using devices with less than 100 mW of power and can be
used outdoors using devices with less than 10 mW of power. When the devices are being used outdoors on
private property, the power may be increased to 100 mW after approval from the Ministry of Defence.
2. For the time being, in all other metropolitan départements, the conditions remain unchanged. The list of the first
38 départements will be progressively added to after 1 January 2003.
3. For the overseas départements (DOM), as well as Saint Pierre and Miquelon and Mayotte, the entire
2400–2483.5 MHz band may be used indoors and outdoors using devices with less than 100 mW of power,
except for the Reunion Islands and Guyana, where the 2420–2483.5 MHz band may be used only outdoors
using devices with less than 100 mW of power. ART reminds operators that these frequencies are used with no
guarantee of nondisruption, and that the installations must respect all measures applying to radio installations
(such as urban planning regulations). These decisions also allow the development of private uses. In particular,
private networks (such as indoor corporate networks) can be established using these technologies.
These conditions are tablulated below in Table of authorised EIRP.
Guidelines for public WLAN experimentation
●
Networks using WLAN technology will be granted a free authorisation for up to 18 months under article L.33-1 of
the Post and Telecommunications Code. These networks may use systems with 100 mW of power (effective
isotropic radiated power (EIRP)) on the entire band, indoors and outdoors. Moreover, in the 2.4 GHz band (and

providing this power limit is respected), fixed point-to-point links can be established for these networks needs, or
frequencies can be requested in other ad hoc bands.
Private and public persons may submit applications to ART, provided that legislation and regulations allow them
to do so.
Applications will be processed in a simplified way, in the spirit of the new "Authorisation" Directive.
ART will send completed applications to the Ministry of Defence. The Ministry will then check that the projects
are not located near any sensitive area and that they are not likely to cause disruptions to military equipment. For
each application, ART will then submit its report and the draft authorisation to the Minister of
Telecommunications.
Applications can be sent from 12 November 2002 so that the first experiments may be launched as soon as early
2003. Full reviews are to be sent to ART at the end of the temporary authorisations to determine whether the
technology guarantees quality and security to users.
Metropolitan departments
