Chapter 1 Product Overview

Thank you for choosing Rosewill’s 802.11n Wireless PIC adapter –
RNX-N250PC. This chapter is to introduce you more about this Wireless
Adapter.

1.1 Package Content

Before getting started, please verify that your package includes the
following items:

1. Rosewill 802.11n Wireless PCI Adapter x 1

2. 2 dBi detachable Antenna x 2

3. Low Profile Bracket x 1

4. Quick Installation Guide x 1

5. Resource CD x 1, including:

 Rosewill Wireless N Client Utility and Driver

 User Manual

1.2 Overview of the Product

PCI Adapter connects you with IEEE802.11n (Draft 2.0) networks at
transfer 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
card 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. Also WPS (PBC and PIN) encryption method
can free you from remembering the long passwords. Complete WMM

Note: Make sure that the package contains the above items. If

any of the listed items are damaged or missing, please contact with your
distributor.

6.1 Auth. \ Encry. Setting - WEP/TKIP/AES

Figure 6-1

Definition of Each Fields in Auth. \ Encry.:

Authentication Type: There are 7 authentication modes supported by

Rosewill Utility. They are open, Shared, LEAP, WPA and
WPA-PSK, WPA2 and WPA2-PSK.

Encryption Type: For open and shared authentication mode, the

available encryption types are None and WEP. For WPA, WPA2,
WPA-PSK and WPA2-PSK authentication mode, the encryption
type supports both TKIP and AES.

WEP Key: Only valid when using WEP encryption algorithm. The

key must match the AP's key. There are several formats to enter
the keys.

Hexadecimal - 40bits: 10 Hex characters.
Hexadecimal - 128bits: 32Hex characters.
ASCII - 40bits: 5 ASCII characters.
ASCII - 128bits: 13 ASCII characters.

6.2 802.1x Setup Details

802.1x is an advance Security function which used for authentication of the
"WPA" and "WPA2" certificate by the server. Sometimes you may need to
use this function when your wireless network under enterprise level.

802.1X: This is introduced in the topic of Section 3-2.
WPA Pre-shared Key: This is the shared key between the AP and

STA. If operating in WPA-PSK and WPA2-PSK authentication
mode, this field must be filled with a key between 8 and 32
characters in length.

Definition of Each Fields in 802.1X Method and Authentication:

Figure 6-3

EAP Method:

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. This 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

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.

Tunnel Authentication:

Protocol: Tunnel protocol, List information include "EAP-MSCHAP

v2", "EAPTLS/Smart card", "Generic Token Card", "CHAP",
"MS-CHAP", "MS-CHAP-V2", "PAP" and "EAP-MD5".

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.

Chapter 8 Troubleshooting

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

- 45 -

Wireless N Adapte r RNX-N250PC User Manual

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.
