This guide is intended for IT administrators, or those who are responsible for

deploying IBM

Access Connections on computers in their organizations. The

guide is intended to provide the information required for installing IBM Access

Connections on one or many computers, provided that licenses for the software are

available for each target computer. The IBM Access Connections application

provides application help, which administrators and users can consult for

information about using the application itself.

Chapter 1. Overview

IBM Access Connections is aconnectivity assistant program which helps to

configure various network connections including wireless LANs. Users can create

and manage location profiles which helps to store the network and Internet

configuration settings that are needed to connect the client computer to anetwork

from aspecific location such as home or work. The network connection can be

made using amodem, awired network adapter, abroadband device (DSL, cable

modem, or ISDN), or awireless network adapter. Virtual private network (VPN)

connections are also supported. By switching between location profiles as you

move your computer from place to place, Access Connections can quickly and

easily help users connect to anetwork without having to reconfigure network

settings manually. Alocation profile supports advanced security settings, default

printer, and automatic application launch.

Access Connections has the ability to support automatic location switching

between Ethernet and wireless LAN connections.

Features

Access Connections includes the following functions:

vCreate new location profiles

Access Connections provides awizard that helps you to create location profiles

that define all of the settings required to connect to various types of networks.

The Connection Status window is opened by default when Access Connections

is started.

vView location profile and connection status

The Connection Status window allows you to view the status of the network

connection associated with each location profile defined in Access Connections

and allows you to switch between location profiles. When you open the window,

status is shown for the network connection and for the components used by the

currently applied location profile.

vSwitch between location profiles

Access Connections allows you to change location profiles. You can simply

choose another location profile from the list and connect to it. Aprogress

indicator window shows the state of the connection. If the connection fails, a

button appears to help you fix the connection.

vSearch for wireless networks.

Access Connections can search for wireless networks that are in range of your

wireless adapter. This feature is useful when you are traveling or in apublic

place and you are not sure about what, if any, wireless networks are available to

you. You can attempt to connect to any wireless networks that are found. If the

connection attempt is successful, anew wireless location profile will be created

using the detected wireless network name and default settings. You can also

manually create alocation profile for adetected wireless network if you know

the appropriate settings.

vAutomatic switching of location profiles

If anetwork associated with your currently applied location profile becomes

unavailable, Access Connection can search for available networks and

automatically switch to amatching location profile. You can automatically switch

between wireless location profiles, and Ethernet location profiles. You can

establish awireless priority list which allows you to define which wireless

location profile will be made active when your computer is in range of multiple

wireless networks, or when more than one location profile uses the same

wireless network name.

vImport and export location profiles

Access Connections allows you to easily share location profiles between different

computers. You can also import location profiles that are created by the network

adminstrator.

vUse the system tray icon

Access Connections provides an icon in the system tray which allows you to

launch the application, view the status of the current location profile, and switch

between profiles.

vCreate location profiles for remote deployment (administrator’s only)

An Access Connections administrator can define location profiles for use the

Access Connections on the client PCs.

Chapter 2. Using Access Connections

This chapter shows you how to use the features of Access Connections.

Viewing connection status

With the Connection Status window, client users can see their network connections

at every link. Furthermore, client users can offer reliable status information to

administrators remotely, so the administrators can diagnose and correct problems.

One window offers you and users accessible, essential information about

connections--and helps them get and stay connected.

13. Connection status

Saving location profiles, settings, time, and reducing help desk calls

Create location profiles with nearly all the settings you need to connect almost

anywhere that network connectivity is available. After profiles are set, Access

Connections lets you easily switch between them. Profiles can be set for automatic

switching between wireless and wired connections based on the highest available

compatible connection speed. They can be set to change default printers, turn on a

VPN, or launch applications by location. Plus, Access Connections helps manage

wireless security, including Wi-Fi Protected Access, WEP, 802.11x and Cisco LEAP.

Profiles can also be centrally managed to simplify deployment.

IBM Access Connections software is included with the purchase of every new IBM

ThinkPad

notebook system. Alist of ThinkPad models that are compatible with

IBM Access Connections can be found at http://www-

306.ibm.com/pc/support/site.wss/migr-4zlnjb.html#ac. There are many other

software utilities available today, typically included with network adapters, that

appear similar in function to Access Connections software. Utilities such as Intel

PROSet and the Cisco Aironet Client Utility (ACU) both provide profile switching

capabilities that control configuration and management for their associated WLAN

adapters. Access Connections software, however, manages amuch more extensive

collection of hardware adapters including LAN, WLAN, WAN (wide area network

or cellular), dial-up, as well as Ethernet-connected broadband (DSL, cable, ISDN).

Supporting all of this networking hardware provides akey benefit: Access

Connections software eliminates the need for administrators to learn and manage

multiple client configuration utilities.

All WLAN configuration utilities, as well as the built-in capability in Microsoft

Windows

XP, enable you to create profiles with settings for network name, SSID,

and security setup, including the definition of awired equivalent privacy (WEP)

key. However, only Access Connections software integrates location-specific control

over the networking and Internet settings that are traditionally set through

multiple facilities, windows, and utilities in Windows. These include:

vFixed IP address or dynamic host configuration protocol (DHCP)

vAuto domain name system (DNS) or explicit DNS addresses and DNS suffixes

vInternet Explorer (IE) home page and proxy settings

vEnable/disable file and printer sharing

vInternet connection firewall

vWindows default printer

vAuto launch virtual private network (VPN) of choice

vAuto launch of any other executable

Without Access Connections software, users might need to take significantly more

steps to set up anetwork connection in alocation. For example, consider a

telecommuter who uses an Ethernet connection both at work and at home. At

work, the user is required to use afixed-IP address with explicit DNS settings and

aproxy server for Internet browsing. But at home, the cable modem dynamically

assigns an IP address (DHCP mode) and the user does not need explicit DNS

settings or aproxy server. To use the notebook at home, the user must modify

Windows network properties to enable DHCP and automatic DNS. And the user

must also turn off the proxy settings in IE tools options or the Internet will be

inaccessible.
