2) This device must accept any interference received, including interference
that may cause undesired operation. This equipment has been tested and
found to comply with the limits for a Class B digital device, pursuant to Part
15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation. This
equipment generates, uses and can radiate radio frequency energy, and if not
installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception, which can be
determined by turning off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
•Reorient or relocate the receiving antenna.
•Increase the separation between the equipment and receiver.

INTRODUCTION
The 11b/g/n 1T1R WLAN Mini Card is a device that allows you
connect your computer to a wireless local area network (LAN). A wireless LAN
allows your system to use wireless Radio Frequency (RF) technology to transmit
and receive data without physically attaching to the network. The Wireless
protocols that come with this product ensure data security and isolation from
interference generated by other radio frequencies.
This card also allows you to take full advantage of your computer’s mobility with
access to real-time information and online services anytime and anywhere. In
addition, this device eliminates the bother of pulling cable through walls and
under furniture. It even allows you to place your system in locations where
cabling is impossible. Modifying and augmenting networks has never been so
easy.
Wireless Network Options
The Peer-to-Peer Network
This network installation lets you set a small wireless workgroup easily and
quickly. Equipped with wireless PC Cards or wireless PCI, you can share files
and printers between each PC and laptop.

You can also use one computer as an Internet Server to connect to a wired global
network and share files and information with other computers via a wireless LAN.
The Access Point Network
The network installation allows you to share files, printers, and Internet access
much more conveniently. With Wireless LAN Cards, you can connect wireless
LAN to a wired global network via an Access Point.

IP Address
Note: When assigning IP Addresses to the computers on the network, remember
to have the IP address for each computer set on the same subnet mask. If your
Broadband Router use DHCP technology, however, it won’t be necessary for you
to assign Static IP Address for your computer.
1. To configure a dynamic IP address (i.e. if your broadband Router has the DHCP
technology), check the Obtain an IP Address Automatically option.
2. To configure a fixed IP address (if you broadband Router is not DHCP
supported, or when you need to assign a static IP address), check the Use the
following IP address option. Then, enter an IP address into the empty field; for
example, enter 192.168.1.254 in the IP address field, and 255.255.255.0 for the
Subnet Mask.
