Wireless Mode when Starting an Ad Hoc Network: Specifies 2.4 GHz 150/54/11  
Mbps to start an Ad Hoc network if no matching network name is found after scanning  
all available modes. This mode also allows the selection of the channel that the  
Wireless Adapter uses. The channels available depend on the regulatory domain. If  
the adapter finds no other ad hoc adapters, the channel that the adapter starts the ad  
hoc network with will be selected automatically. The Adapter must match the wireless  
mode and channel of the clients it associates.  
¾
802.11 Authentication Mode: Select which mode the Adapter uses to authenticate to  
an access point:  
Auto causes the adapter to attempt authentication using shared, but switches it  
to open authentication if shared fails.  
Open enables an adapter to attempt authentication regardless of its WEP  
settings. It will only associate with the access point if the WEP keys on both the  
adapter and the access point match.  
Shared only allows the adapter to associate with access points that have the  
same WEP key.  
For infrastructure (access point) networks, click Preferred APs… to specify four access  
points at most to the client adapter that attempts to be associated to the access points.  
The four access points have different priorities; the frontal has the higher priority.

Chapter 4 WPS Configuration  
WPS (Wi-Fi Protected Setup) function allows you to add a new wireless device to an  
existing network quickly.  
If the wireless card supports WPS, you can establish a wireless connection between  
wireless card and router using either Push Button Configuration (PBC) method or PIN  
method.  
First, the WPS software should be installed. Insert the Resource CD into your CD-ROM  
drive, and open the folder named RNX-N150PCe. Double-click WPS.exe in the proper  
folder to start the installation, then the following screen for preparing setup will appear.  
Figure 4-1  
Then, please follow the clue of the Operation System to complete the WPS installation.  
After that, WPS function can be enabled. Here we will introduce two ways to configure the  
WPS (For the configuration of WPS, here takes the Wireless Router of our company for  
example).

Appendix B: Glossary

¾
802.11b - The 802.11b standard specifies a wireless product networking at 11 Mbps  
using direct-sequence spread-spectrum (DSSS) technology and operating in the  
unlicensed radio spectrum at 2.4GHz, and WEP encryption for security. 802.11b  
networks are also referred to as Wi-Fi networks.  
802.11g- specification for wireless networking at 54 Mbps using direct-sequence  
spread-spectrum (DSSS) technology, using OFDM modulation and operating in the  
unlicensed radio spectrum at 2.4GHz, and backward compatibility with IEEE 802.11b  
devices, and WEP encryption for security.  
Ad-hoc Network - An ad-hoc network is a group of computers, each with a Wireless  
Adapter, connected as an independent 802.11 wireless LAN. Ad-hoc wireless  
computers operate on a peer-to-peer basis, communicating directly with each other  
without the use of an access point. Ad-hoc mode is also referred to as an  
Independent Basic Service Set (IBSS) or as peer-to-peer mode, and is useful at a  
departmental scale or SOHO operation.  
¾
DSSS - (Direct-Sequence Spread Spectrum) - DSSS generates a redundant bit  
pattern for all data transmitted. This bit pattern is called a chip (or chipping code).  
Even if one or more bits in the chip are damaged during transmission, statistical  
techniques embedded in the receiver can recover the original data without the need  
of retransmission. To an unintended receiver, DSSS appears as low power wideband  
noise and is rejected (ignored) by most narrowband receivers. However, to an  
intended receiver (i.e. another wireless LAN endpoint), the DSSS signal is recognized  
as the only valid signal, and interference is inherently rejected (ignored).  
¾
¾
FHSS - (Frequency Hopping Spread Spectrum) - FHSS continuously changes (hops)  
the carrier frequency of a conventional carrier several times per second according to  
a pseudo-random set of channels. Because a fixed frequency is not used, and only  
the transmitter and receiver know the hop patterns, interception of FHSS is extremely  
difficult.  
Infrastructure Network - An infrastructure network is a group of computers or other  
devices, each with a Wireless Adapter, connected as an 802.11 wireless LAN. In  
infrastructure mode, the wireless devices communicate with each other and to a  
wired network by first going through an access point. An infrastructure wireless  
network connected to a wired network is referred to as a Basic Service Set (BSS). A  
set of two or more BSS in a single network is referred to as an Extended Service Set

(ESS). Infrastructure mode is useful at a corporation scale, or when it is necessary to  
connect the wired and wireless networks.  
¾
Spread Spectrum - Spread Spectrum technology is a wideband radio frequency  
technique developed by the military for use in reliable, secure, mission-critical  
communications systems. It is designed to trade off bandwidth efficiency for reliability,  
integrity, and security. In other words, more bandwidth is consumed than in the case  
of narrowband transmission, but the trade off produces a signal that is, in effect,  
louder and thus easier to detect, provided that the receiver knows the parameters of  
the spread-spectrum signal being broadcast. If a receiver is not tuned to the right  
frequency, a spread-spectrum signal looks like background noise. There are two  
main alternatives, Direct Sequence Spread Spectrum (DSSS) and Frequency  
Hopping Spread Spectrum (FHSS).  
¾
SSID - A Service Set Identification is a thirty-two character (maximum) alphanumeric  
key identifying a wireless local area network. For the wireless devices in a network to  
communicate with each other, all devices must be configured with the same SSID.  
This is typically the configuration parameter for a wireless PC card. It corresponds to  
the ESSID in the wireless Access Point and to the wireless network name. See also  
Wireless Network Name and ESSID.  
¾
WEP - (Wired Equivalent Privacy) - A data privacy mechanism based on a 64-bit or  
128-bit or 152-bit shared key algorithm, as described in the IEEE 802.11 standard. To  
gain access to a WEP network, you must know the key. The key is a string of  
characters that you create. When using WEP, you must determine the level of  
encryption. The type of encryption determines the key length. 128-bit encryption  
requires a longer key than 64-bit encryption. Keys are defined by entering in a string  
in HEX (hexadecimal - using characters 0-9, A-F) or ASCII (American Standard Code  
for Information Interchange – alphanumeric characters) format. ASCII format is  
provided so you can enter a string that is easier to remember. The ASCII string is  
converted to HEX for use over the network. Four keys can be defined so that you can  
change keys easily.  
¾
¾
Wi-Fi - A trade name for the 802.11b wireless networking standard, given by the  
industry standards group promoting interoperability among 802.11b devices.  
WLAN - (Wireless Local Area Network) - A group of computers and associated  
devices communicate with each other wirelessly, which network serving users are  
limited in a local area.

Appendix C: FAQ  
This chapter provides solutions to problems that may occur during the installation and  
operation of the Wireless Adapter. Read the descriptions below to solve your problems.  
1. I cannot communicate with the other computers linked via Ethernet  
in the Infrastructure configuration.  
1. Make sure that the PC to which the Adapter is associated is powered on.  
2. Make sure that your Adapter is configured on the same channel and with the  
same security options as with the other computers in the Infrastructure  
configuration.  
2. What should I do when the computer with the Adapter installed is  
unable to connect to the wireless network and/or the Internet?  
1. Check that the LED indicators for the broadband modem are indicating normal  
activity. If not, there may be a problem with the broadband connection.  
2. Check that the LED indicators on the wireless router are functioning properly. If  
not, check that the AC power and Ethernet cables are firmly connected.  
3. Check that the IP address, subnet mask, gateway, and DNS settings are correctly  
entered for the network.  
4. In Infrastructure mode, make sure the same Service Set Identifier (SSID) is  
specified on the settings for the wireless clients and access points.  
5. In Ad-Hoc mode, both wireless clients will need to have the same SSID. Please  
note that it might be necessary to set up one client to establish a BSS (Basic  
Service Set) and wait briefly before setting up other clients. This prevents several  
clients from trying to establish a BSS at the same time, which can result in  
multiple singular BSSs being established, rather than a single BSS with multiple  
clients associated to it.  
6. Check that the Network Connection for the wireless client is configured properly.  
If Security is enabled, make sure that the correct encryption keys are entered on  
both the Adapter and the access point.  
3. I can’t find any wireless access point / wireless device in ‘Site  
Survey’ function.  
1. Click ‘Rescan’ for few more times and see if you can find any wireless access  
point or wireless device.  
2. Please move closer to any known wireless access point.  
3. ‘Ad hoc’ function must be enabled for the wireless device you wish to establish a  
direct wireless link.  
4. Please adjust the position of network card (you may have to move your computer  
if you’re using a notebook computer) and click ‘Rescan’ button for few more times.

If you can find the wireless access point or wireless device you want to connect  
by doing this, try to move closer to the place where the wireless access point or  
wireless device is located.  
4. I cannot establish connection with a certain wireless access point  
1. Click ‘Add to Profile’ for few more times.  
2. If the SSID of access point you wish to connect is hidden (nothing displayed in  
3. ‘SSID’ field in ‘Site Survey’ function), you have to input correct SSID of the access  
point you wish to connect. Please contact the owner of access point to ask for  
correct SSID.  
4. You have to input correct passphrase / security key to connect an access point  
with encryption. Please contact the owner of access point to ask for correct  
passphrase / security key.  
5. The access point you wish to connect only allows network cards with specific  
MAC address to establish connection. Please go to ‘Status’ menu and write the  
value of ‘MAC Address’ down, then present this value to the owner of access  
point so he / she can add the MAC address of your network card to his / her  
access point’s list.  
5. The network is slow / having problem when transferring large files  
1. Move closer to the place where access point is located.  
2. There could be too much people using the same radio channel. Ask the owner of  
the access point to change the channel number.
