Connecting the Ethernet Adapter to Your Network
There are two network scenarios as below:
Ad-hoc
Networking
Also known as a peer-to-peer network, an ad-hoc network is
one that allows all workstations and computers in the network
to act as servers to all other users on the network.
Users on the network can share files, print to a shared printer,
and access the Internet with a shared modem. However, with
ad-hoc networking, users can only communicate with other
wireless LAN computers that are in the same wireless LAN
workgroup, and are within range.
<PC to Network Printer>
<PC to PC >
Infrastructure
Networking
Infrastructure networking differs from ad-hoc networking in
that it includes an access point. Unlike the ad-hoc structure
where users on the LAN contend the shared bandwidth, on
an infrastructure network, the access point can manage the
bandwidth to maximize bandwidth utilization.
Additionally, the access point enables users on a wireless
LAN to access an existing wired network, allowing wireless
users to take advantage of the wired networks resources,
such as Internet, email, file transfer, and printer sharing.
Infrastructure networking has the following advantages over
ad-hoc networking:
Extended range: each wireless LAN computer within the
range of the access point can communicate with other
wireless LAN computers within range of the access point.

bridges the gap between wireless LANs and their wired
counterparts.

Please make sure that your PC already has TCP/IP protocol installed. If not, please
contact your administrator for details if you have problems of setting up this TCP/IP
protocol in your PC.
Note!
Even your adapter is not connected with PC, but other Ethernet device, such as
printer server. You still can install the Wireless Navigator in any PC located in the
same IP subnet with the adapter. This utility can search the adapter via both wired
and wireless Ethernet so that you still manage the adapter remotely.
Step 1: Insert the installation CD-ROM into the CD-ROM drive. Run SETUP.EXE program
on the CD-ROM. The following window will be shown automatically.

4. Configuring the Ethernet Adapter
The Info Tab
(Connected with wireless LAN)
(NOT Connected with any wireless LAN)
SSID: displays current SSID this
adapter uses.
If the adapter found no AP or any
other ad-hoc device, then SSID will
show “non-spec” . Please make
sure that your wireless LAN is
working properly under the effective
reach range of the adapter
Channel: displays the channel that
the adapter uses now.
BSSID: displays MAC address of the
AP that the adapter is connecting
with.
Transmission Rate: the transfer
data rate that the adapter is using in
wireless LAN
Link Quality (%): displays the
wireless LAN connection integrity
when connected to an AP.
MAC address: displays the unique
serial number burned into the
adapter that identifies itself from
other Ethernet devices.
IP address: displays the adapter’s
current IP address assigned by AP
or router.
Firmware Revision: displays the
adapter’s current firmware version
Results of the most recent scan:
displays the recent scan over the
wireless LAN, and information of the
found and reachable APs will be
listed
When you re-load the web page, the
result will be updated once again.

of transfer rates.
Access point density: enables you
to set the relative number of access
points near the WS300. Use this
setting to reduce channel overlap
and interference:
• Low: 1-2 nearby APs
• Medium: 3-4 nearby APs
• High: 5 or more nearby APs
When connected in an infrastructure
or ad-hoc mode, a list of nearby APs
or peers is displayed at the bottom of
the Info screen. When you re-load
