Introduction
1.1
Welcome
PCI Adapter connects you with IEEE802.11n networks at receiving rate up to an incredible 300Mbps!
By using the reflection signal, 802.11n technology increases the range and reduces "dead spots” in the
wireless coverage area.
Unlike ordinary wireless networking of 802.11b/g standards that are confused by wireless reflections,
802.11n can actually use these reflections to increase four times transmission range of 802.11g
products.
Besides, when both ends of the wireless link are 802.11n products, The PCI can utilize twice radio
band to increase three times transmission speed of ordinary 802.11g standard products, and can comply
with backwards 802.11b/802.11g standards.
Soft AP supported by PCI Adapter can help you establish wireless LAN networking with lowest cost.
Besides, WPS (PBC and PIN) encryption method can free you from remembering the long passwords.
Complete WMM function makes your voice and video more smooth.

Start
5.1.1
Start RaUI
When starting RaUI, the system will connect to the AP with best signal strength
without setting a profile or matching a profile setting. When starting RaUI, it will
issue a scan command to a wireless NIC. After two seconds, the AP list will be
updated with the results of a BSS list scan. The AP list includes most used fields, such
as SSID, network type, channel used, wireless mode, security status and the signal
percentage. The arrow icon indicates the connected BSS or IBSS network. The dialog
box is shown in Figure 2-1.
Figure 2-1-1 RaUI section introduction
There are three sections to the RaUI dialog box. These sections are briefly described
as follow.
Button Section: Include buttons for selecting the Profile page, Network page,
Advanced page, Statistics page, WMM page, WPS page, the About button, Radio
On/Off button and Help.

When starting RaUI, a small Ralink icon appears in the notifications area of the
taskbar, as shown in Figure 2-1-15. You can double click it to maximize the dialog
box if you selected to close it earlier. You may also use the mouse's right button to
close RaUI utility.

802.1x Setting
802.1x is used for authentication of the "WPA" and "WPA2" certificate by the server.
34
Authentication type:
 PEAP: Protect Extensible Authentication Protocol. PEAP transport securely
authenticates data by using tunneling between PEAP clients and an authentication
server. PEAP can authenticate wireless LAN clients using only server-side
certificates, thus simplifying the implementation and administration of a secure
wireless LAN.
 TLS/Smart Card: Transport Layer Security. Provides for certificate-based and
mutual authentication of the client and the network. It relies on client-side and
server-side certificates to perform authentication and can be used to dynamically
generate user-based and session-based WEP keys to secure subsequent
communications between the WLAN client and the access point.
 TTLS: Tunneled Transport Layer Security. This security method provides for
certificate-based, mutual authentication of the client and network through an
encrypted channel. Unlike EAP-TLS, EAP-TTLS requires only server-side
certificates.
 EAP-FAST: Flexible Authentication via Secure Tunneling. It was developed by
Cisco. Instead of using a certificate, mutual authentication is achieved by means of
a PAC (Protected Access Credential) which can be managed dynamically by the
authentication server. The PAC can be supplied (distributed one time) to the client
either manually or automatically. Manually, it is delivered to the client via disk or a
secured network distribution method. Automatically, it is supplied as an in-band,
over the air, distribution. For tunnel authentication, only support "Generic Token
Card" authentication.
 LEAP: Light Extensible Authentication Protocol is an EAP authentication type
used primarily by Cisco Aironet WLANs. It encrypts data transmissions using
dynamically generated WEP keys, and supports mutual authentication.
 MD5-Challenge: Message Digest Challenge. Challenge is an EAP authentication
type that provides base-level EAP support. It provides for only one-way
authentication - there is no mutual authentication of wireless client and the
network.(Only support XP)
Session Resumption: The user can choose "Disable" and "Enable".
Tunnel Authentication:
 Protocol: Tunnel protocol, List information include "EAP-MSCHAP v2",
"EAP-TLS/Smart card", "Generic Token Card", "CHAP", "MS-CHAP",
"MS-CHAP-V2", "PAP" and "EAP-MD5".
 Tunnel Identity: Identity for tunnel.
35
Tunnel Password: Password for tunnel.
ID \ PASSWORD
 Authentication ID/Password: The identity, password and domain name for server.
Only "EAP-FAST" and "LEAP" authentication can key in domain name. Domain
names can be keyed in the blank space.
 Tunnel ID/Password: Identity and Password for the server..
Client Certification

Use Client certificate: Client certificate for server authentication.
EAP Fast
Allow unauthenticated provision mode: During the PAC can be provisioned
(distributed one time) to the client automatically. It only supported "Allow
unauthenticated provision mode" and use "EAP-MSCHAP v2" authentication to
authenticate now. It causes to continue with the establishment of the inner tunnel
even though it is made with an unknown server.
 Use protected authentication credential: Using PAC, the certificate can be provided
to the client manually via disk or a secured network distribution method.
Server Certification


Certificate issuer: Select the server that issues the certificate.

Trouble Shooting
This chapter provides solutions to problems that may occur during the installation and operation of PCI
Adapter. Read the descriptions below to solve your problems.
1. The PCI Adapter does not work properly.
Reinsert PCI Adapter into your PC’s PCI slot. Right click on My Computer and select Properties.
Select the device manager and click on the Network Adapter. You will find PCI Adapter if it is installed
successfully. If you see the yellow exclamation mark, the resources are conflicting. You will see the
status of PCI Adapter. If there is a yellow question mark, please check the following: Make sure that
your PC has a free IRQ (Interrupt Request, a hardware interrupt on a PC.) Make sure that you have
inserted the right adapter and installed the proper driver. If PCI Adapter does not function after
attempting the above steps, remove it and do the following: Uninstall the driver software from your PC.
Restart your PC and repeat the hardware and software installation as specified in this User Guide.
2. I cannot communicate with the other computers linked via Ethernet in the Infrastructure
configuration.
Make sure that the PC to which PCI Adapter is associated is powered on. Make sure that PCI Adapter
is configured on the same channel and with the same security options as with the other computers in
the Infrastructure configuration.
3. What should I do when the computer with PCI Adapter installed is unable to connect to the
wireless network and/or the Internet?
Check that the LED indicators for the broadband modem are indicating normal activity. If not, there
may be a problem with the broadband connection. 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.
Check that the IP address, subnet mask, gateway, and DNS settings are correctly entered for the
network. In Infrastructure mode, make sure the same Service Set Identifier (SSID) is specified on the
settings for the wireless clients and access points. 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. 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 PCI Adapter and the access point.
