http://www.L‐com.com Introduction
The WLAN-LCUSB2415 wireless network adapter is a powerful 32-bit USB
Adapter that installs quickly and easily into PCs or Notebook. This adapter can be
used in Ad-Hoc mode to connect with a wireless access point or router for access
to the internet in your enterprise or home network.
WLAN-LCUSB2415 wireless USB adapter connects you with 802.11n networks at
up to a 150Mbps. And for added versatility, it can also interoperate with all
802.11g (up to 54Mbps) and 802.11b (up to 11Mbps) products found in homes,
business, and public wireless hotspots around the country. And in either mode,
your wireless communications are protected by industrial-strength WPA/WPA2,

authentication.

Shared –With the Shared authentication, the station requesting
authentication must provide a secret key (which can be obtained from
network administrator) using a secure channel (independent of the 802.11
wireless communications channel).

LEAP –(Light Extensible Authentication Protocol) is an EAP authentication
method used primarily on Cisco Aironet wireless networks. This protocol
encrypts transmitted data using dynamically generated WEP keys, and
supports two way authentications.

WPA and WPA2 –IEEE 802.1x protocol is used for authentication and AES
or TKIP for encryption.

WPA PSK and WPA2 PSK–Station requesting authentication must provide a
WPA Preshared Key. AES or TKIP are used for encryption.

Authentication: Open and Shared
Authentication –Change authentication method.
Encryption –Select None or WEP.
Use 802.1x –Check this option to use IEEE 802.1x for authentication. IEEE

only). The key should be 8 to 32 characters in length.
16
http://www.L‐com.com Profile configuration – 802.1x Tab
Settings on this Tab allow IEEE 802.1x protocol. All information can be obtained
from wireless network administrator. Appearance of this Tab depends on options
selected from EAP method and Tunnel Authentication lists.
 PEAP –Protect Extensible Authentication Protocol. PEAP transports secured
authentication 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 secure wireless network.

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 AP.

TTLS –Tunnel 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, it requires only server-side
certificates.

EAP-FAST –Flexible Authentication via secured 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 provisioned
(distributed on time) to the client either manually or automatically. Manual
provisioning is delivered to the client via disk or secured network distribution
method. Automatic provisioning is an in-band, over the air, distribution. For
tunnel authentication, only support “Generic Toke Card” authentication now.

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.

Troubleshooting
This chapter provides solutions to problems that may occur during the installation
and operation of the wireless USB adapter.
1.
The Wireless USB Adapter does not work properly.
 Reinsert the Wireless Adapter into your PC’s USB port.



Right click on My Computer and select Properties. Select the device
manger and click on Network Adapter. You will find the Adapter if it is
installed successfully. If you see the yellow exclamation mark, the
resources are conflicting. You will see the status of the 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
32
http://www.L‐com.com 

proper driver. If the Adapter does not function after attempting the above
steps, remove the adapter 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 Manual.
2.
I cannot communicate with other computers linked via Ethernet in the
Infrastructure configuration.
 Make sure the power of the PC with Adapter associated is on.
 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.
3.
What should I do when the computer with the Adapter installed is
unable to connect to the wireless network and/or the Internet?
 Check the LED indicators from the broadband modem, see if LED
indicating normal activity. If not, there may be problem with the
broadband connection.
 Check the LED indicators on the wireless router or AP to see if they are
functioning properly. If not, check if the AC power and Ethernet cable are
firmly connected.
 Check 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 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 if the Network Connection for the wireless client is configured
properly.
 If Security is enabled, make sure the correct encryption keys are entered
on both the Adapter and the access point.
