BEFORE YOU START
1. Confirm Box Contents
CONNECTING YOUR WLAN
USB ADAPTER TO PC
Quick Start Guide
Connect your WLAN USB
dongle to your PC.
Install driver.

Wireless LAN network defined by IEEE 802.11b/g standard committee
could be configured as :
Ad Hoc wireless LAN.
Infrastructure wireless LAN.
Ad Hoc network is a group of PCs installed with wireless LAN cards, this
group of PCs is called a BSS (Basic Service Set). PCs in this group can use
their wireless LAN cards to communicate with each other, but can not
connect to the Internet.
Ad Hoc WirelessNetwork Infrastructure Wireless Network
The most obvious difference between Infrastructure wireless network
and Ad Hoc wireless network is that the PCs in Infrastructure wireless
network can access the resource in the Internet through Access Point.
Depending on your requirement, you can easily set up your PC’s
network to be a “Ad Hoc” or “Infrastructure” wireless network. Generally
speaking, if in your network, there is an Access Point in it, we recommend
you to set your network as an “Infrastructure”, so it can connect to
the Internet.

To use the WLAN Mini USB Adapter with a computing device, the WLAN
Mini USB Adapter must be equipped with an USB 2.0 Interface. All
drivers and supporting software for the WLAN Mini USB Adapter must be
installed and configured first.
Ask your system administrator for the following information, which you
may need to provide during driver installation :
Your Wireless Client Name.
Your Wireless SSID.
Your computer’s unique client name and workgroup name.
For your network account, your user name and password.
Your IP address, gateway address, and subnet mask if you’re not
using a DHCP client.
Any computer on a network is identified by a unique network address.
There are two methods to assign a network address to a computer on a
TCP/IP network :
Static IP addressing.
Dynamic IP addressing (DHCP Client).
In network with static IP addressing, the network administrator manually
assigns an IP address to each computer. Once a static IP address is
assigned, a computer uses the same IP address every time it reboots and
logs on to the network. You may manually change the IP address in the
Network Properties dialog box. Network using static IP address is easy to
set up and do not require additional network management software.
In network with dynamic IP addressing, a DHCP server in the network
dynamically assigns IP addresses to all clients every time they log on to
the network. Network using dynamic IP address requires setting up and
running a DHCP Server.
