Tips for using the wireless LAN feature
• Place your computer so that there are as few obstacles as possible between the wireless LAN access
point and the computer.
• For the best connection of the wireless LAN feature, open your computer display to an angle of slightly
more than 90 degrees.
• If you use the wireless feature (the 802.11 standard) of your computer simultaneously with a Bluetooth
option, data transmission speed can be delayed and the performance of the wireless feature can be
degraded.
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.
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, condential and intact.
For both types of network, the Client Security Solution and TPM ensure data condentiality and availability
by providing a hardware- and software-based architecture for better protection of the sensitive keys, identity
information, and condential data. Also, for wireless networks the TPM hardware provides enhanced
authentication and session condentiality 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.
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
a city or an entire country, by use of multiple antenna sites or satellite systems maintained by wireless
service providers.
