Sweex Wireless LAN PCI Card 11G
Introduction
Thank you for buying this Sweex wireless LAN PCI card which allows you to set up a wireless network quickly and simply. The Sweex wireless
LAN PCI card complies with all international standards for wireless communication such as IEEE 802.11g and CE.
The Sweex wireless LAN PCI card is compatible with all major operating systems such as Windows 98 Second Edition, Windows 2000 and
Windows XP. The PCI card supports transmission speeds of up to 54 Mbps which is more than enough for wireless communication with the
Internet, for example. Depending on conditions, the PCI card has a range of up to 50 metres indoors and 100 metres outdoors.
The Sweex wireless LAN PCI card has auto fallback. This means that the data transmission automatically switches back if a wireless LAN device
does not satisfy the 802.11g standard, for example. Auto fallback also offers a solution if there are obstacles in the line-of-sight of the wireless
LAN. In terms of security, the Sweex wireless LAN PCI card is compatible with the WEP 64/128 protocol which means that data is encrypted
before it is transmitted. This means it is almost impossible to eavesdrop on the communication.
We advise you to read this manual carefully first to guarantee correct operation of the Sweex wireless LAN PCI card. If you should nevertheless
experience problems in the installation or operation of the Sweex wireless LAN PC card, you can find more information on our web site
http://www.sweex.com .

It is possible that you may not have sufficient rights under Windows 2000 to install drivers and software. If that is the case, contact your system
administrator. You need administrator rights to install new hardware and software.
If you are using Windows 2000 or XP as your operating system, you will see a message stating that the driver has not been digitally signed by
Microsoft. This is not a problem for the operation of the hardware. Click on Yes to continue.
The following screen appears. Select the code for your country and click on ‘Next’
Procedure for installing the 11G wireless PCI card hardware
Take the following precautions before installing the hardware:
1. Ensure the PC is switched off and is not connected to the power supply.
2. Also disconnect the printer and the monitor cable, because they have their own power supply, so that you are certain that there is no voltage
on the PC.
3. Then unscrew the computer case.
4. Once you have unscrewed the computer case, make sure you discharge any static electricity from yourself by touching a (bare) central
heating pipe or an unlagged water pipe. Take care not to use a magnetic screwdriver. Once again touch the metal frame of the PC case. Avoid
touching any contact points in the PC, PC card or memory.
5. Find a free PCI slot and remove the metal blanking plate inside the relevant slot in the computer case. It might be a little hard to insert the
card into the PCI slot. If this happens, do not use force but try a different free slot.
6. Once the card has been inserted successfully, check that all the other cards are still inserted in their PCI slots correctly. Sometimes when
inserting a PCI card, the other PCI cards are moved upwards causing the relevant card or even the entire PC to stop working.
7. Next replace the computer case cover and correctly reconnect all cables that were removed from the PC.
8. Connect the supplied aerial to the card.
9. Now switch the PC back on.
NB
Never use the wireless 11G PCI card without the aerial to prevent damage to the card.
Once your operating system has restarted, Windows will detect new hardware. If Windows asks for the software, click on ‘Cancel’ and follow the
installation procedure below.
Software installation
Insert the supplied CD-ROM in to the CD drive of your computer system, click on the Start button ➔ Run ➔ enter the command x:\setup.exe
and click on ‘OK’, where X is the drive letter of your CD drive.

More Settings Click on this button to modify the settings such as the channel, transmission speed, network type,
SSID and to turn WEP encryption on or off. When you turn WEP on, the ‘WEP More’ button
becomes active so that you can set the encryption data. See the Settings section for more
information.
Link Status This field shows the status of the wireless link.
Signal Strength This field shows the strength of the signal. The stronger the signal, the higher and more stable the
speed of the wireless link will be.
Link Quality This field shows the quality of the link.
TX Frame This field shows the number of frames or data packets that have been successfully sent.
RX Frame This field shows the number of frames or data packets that have been successfully received.
General Connection Settings
Channel Here you can select the channel to be used for the wireless communication. All computers within a
wireless network should use the same channel.
TxRate You can set the transmission/reception speed in this field. You can choose 11, 5.5, 2 or 1 Mbps.
You can also choose the ‘Auto’ option so the speed is selected automatically based on the quality
and signal strength of the link. If the signal strength weakens, the speed of the link will also fall.
SSID This is the unique name that is used for the wireless network. The name may be up to 32
characters long. Computers can only link to wireless networks with the same name.
Any If you check this option, the adapter will attempt to link to the first wireless network it detects,
irrespective of the SSID name and the channel that is set.
Network Type Here you can choose ‘Infrastructure’ if you are using an access point (AP) within your wireless
network. All communication then runs via the AP.
‘Ad Hoc’ is a special mode if you do not have an access point. When you select ‘Ad Hoc’ mode,
two 11g devices can communicate with one another directly.
Change button Click on this button to change the General Connection Settings. After making the changes, click on
‘Apply’ to implement the changes.
Encryption Setting Here you can check the ‘WEP’ option which activates the ‘WEP More’ button. In terms of security, it
is advisable to activate WEP encryption with 128-bit encryption. See the WEP settings section for
more information.

Click on ‘Finish’ to complete the installation.
The ‘Utility Selection’ now appears. You can accept the default settings ‘Use RaConfig’
Here are some terms you will encounter in the wireless configuration
Network Adapter If everything has worked properly, here you will see the wireless network adapter (ZD1201) IEEE
802.11g device.
Available Network This screen section shows the available wireless networks. Normally you will only see your own
wireless network, but it is possible that you may see, for example, your neighbour’s wireless
network. This shows why it is important to use WEP encryption. SSID gives the name of the
wireless network and Strength the strength of the wireless signal. You can connect to the wireless
network in two ways. You can double click on the name of the wireless network after which the
connection is set up. Of you can just select the name and then click on the ‘Connect this’ site
button.
Current Network Information This screen section displays information on the current status of the wireless network connection.
You can see which channel is being used, the operation mode (Infrastructure or Ad Hoc), the name
of the wireless network, the connection speed and the WEP security setting (On or Off).

Authentication Mode The authorisation mode should be the same throughout the wireless network. This means that if
your access point is set to Shared Key, you must also set your 11g device to Shared Key.
•
Open System – This setting means that no authorisation is required to use the wireless
network.
•
Shared Key – Only computers using the correct WEP setting (key) can link to the wireless
network.
•
Auto – If you choose this option, the 11g device itself will decide whether or not authorisation
using a WEP key should be used. The WEP key, of course, must be set correctly.
Key Length You can choose between a 64-bit or a 128-bit key. The longer the key you use (128-bit), the
greater the security level. As noted earlier, greater security will cause a slight impairment in
performance. From the point of view of security, a higher encryption protocol is advisable.
Default Key ID You can specify up to 4 different WEP keys. In this field you specify which key (1 to 4) you want
to be used as the default. For example, you can set in the profile that key 1 is used for home and
key 2 in the office.
Key 1 t/m Key 4 Here you should specify the encryption key you want. If you choose 64-bit encryption, you should
enter 10 characters, which must fall within the following range: A to F or a to f or 0 to 9. An
example of a 64-bit key is: 0123456aef. With 128-bit encryption you should enter a key of 26
characters. Again the characters should fall within the following range: A to F or a to f or 0 to 9. An
example of a 128-bit key is: 01234567890123456789abcdef.
Power Saving Mode
Enable auto power saving If you check this option, the 11g device will attempt to handle the necessary power as efficiently as
possible. This is not so important on a desktop computer, but notebook users can use this option to
increase the usage time of their battery. You can set Power Saving mode on a scale from 1 to 4. 1
means little power saving and 4 means optimum power saving. You should bear in mind that
optimum power saving will cause a slight impairment in performance.
Fragmentation Threshold This setting determines the maximum size of a data packet. If the value is greater than the setting
you select here, the data packet will be split into two or more separate packets. If you set this
value too low, error messages may be generated.
RTS/CTS Threshold Here you specify the maximum size of a data packet to emit an RTS/CTS (Request To Send/ Clear
To Send) signal. If a data packet is smaller than the value you set here, no RTS/CTS will be sent
but the data packet will be sent directly to the wireless network.
For a comprehensive description of the functions of this Sweex wireless 11g card, please refer to the
English manual on the CD-ROM.

settings quickly, for example for working at home and in the office.
Load profile setting Here you can load the settings of a profile you have previously saved. The new settings are
activated immediately.
Write current setting to profile Once you have specified all the settings you want, you can save them by clicking on this button. Do
not forget to specify a unique name in the ‘Profile Name’ field.
Load factory default setting Click on this button to load and activate the default factory settings.
Other
Advanced Setting Click on this button to display the screen for advanced settings such as Power Saving Mode.
Information Click on this button to display comprehensive information about the version of the software driver,
firmware, MAC address etc.
WEP settings
As stated earlier, it is important to secure your wireless network against potential misuse. For example, you would not appreciate it if your
neighbour used your wireless network to surf the Internet at your expense. You can set up your 11g device for 64 or 128-bit encryption. We
advise you to opt for 128-bit encryption.. The use of WEP (Wireless Encryption Protocol) requires extra computing power so performance will be
a little lower than without WEP. However, in practice this will be barely noticeable.
