Wireless networking setup
To use the built-in wireless networking card (the 802.11 standard) to communicate, start the Access
Connections program.
Note: Before you start setting up wireless networking connections by using the Access Connections
program, obtain a Network Name (SSID) and your encryption information from your network administrator.
The Access Connections program, a connectivity assistant program, can easily enable one network adapter
and disable the other adapters on demand. After setting up your wireless networking connection, you can
use the program to quickly switch the network settings.
If no WiFi credentials are stored on the Instant Media Mode card, when you switch your computer to
Instant Media Mode, a pop-up dialog box will be displayed to request the WiFi credentials. Input your
WiFi credentials to set up the wireless connection.
Note: If the computer is connected to a wireless network when you are using the Windows 7 operating
system, after switching to Instant Media Mode, the Instant Media Mode card will automatically attempt to
connect to the wireless network that was previously in use in the Windows 7 operating system environment.
If WiFi credentials are stored on the Instant Media Mode card, when you switch your computer to Instant
Media Mode, the wireless connection will be automatically established using the credentials stored on the
Instant Media Mode card. You can update your credentials and other wireless connection parameters
in the WiFi settings interface.
Wireless security features
Advances in wireless technology require that we manage your security more reliably than ever. Therefore,
Lenovo has extended its Embedded Security Subsystem called the Trusted Platform Module (TPM) to
encompass virtually all of our ThinkPad and desktop computer lines. This security subsystem helps protect
data, hardware, network access and communications, both wired and wireless, on select ThinkPad and
desktop PCs.
The Embedded Security Subsystem provides hardware-based protection of critical security information,
including passwords, encryption keys, and electronic credentials. It also helps identify computer users
involved in transactions, and helps establish that data transmissions are authentic, confidential and intact.
For both types of network, the Client Security Solution and TPM ensure data confidentiality and availability
by providing a hardware- and software-based architecture for better protection of the sensitive keys, identity
information, and confidential data. Also, for wireless networks the TPM hardware provides enhanced
authentication and session confidentiality by concealing authentication credentials for industry-standard
802.1x protocols and Cisco LEAP.
Note: Client Security Solution is not preinstalled on your system. To download Client Security Solution,

Wireless upgradeable ThinkPad models
Your computer can be wireless upgradeable. This means that your computer has an antenna that can
support wireless LAN access when wireless LAN access points are available. Wireless devices are available
from Lenovo. For more information, refer to "Finding ThinkPad options" on page 93.
Using wireless WAN connections
Wireless Wide Area Network (wireless WAN) enables you to establish wireless connections over remote
public or private networks. These connections can be maintained over a large geographical area, such as
