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. A list 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 a much 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 a key 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 a wired 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:
v Fixed IP address or dynamic host configuration protocol (DHCP)
v
Auto domain name system (DNS) or explicit DNS addresses and DNS suffixes
v
Internet Explorer (IE) home page and proxy settings
v
Enable/disable file and printer sharing
v
Internet connection firewall
v
Windows default printer
v
Auto launch virtual private network (VPN) of choice
v
Auto launch of any other executable
Without Access Connections software, users might need to take significantly more
steps to set up a network connection in a location. For example, consider a
telecommuter who uses an Ethernet connection both at work and at home. At
work, the user is required to use a fixed-IP address with explicit DNS settings and
a proxy 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 a proxy 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.
