15-64 Chapter 15 Configuring Network and Internet Connections
Key Points
Key Terms
■ Repairing a network connection forces several actions, the most important of
which include renewing an IP address lease (which you can also do by typing
ipconfig /renew at the command prompt) and flushing the DNS cache (which
you can also do by typing ipconfig /flushdns at the command prompt).
■ You can configure a wireless client to operate in two modes: ad-hoc mode, in
which there is no AP, and infrastructure mode, in which an AP is used. An ad-hoc
network offers little security or configurability, and is sometimes used in small
workgroup environments. An infrastructure network, which provides greater security
and configurability, is the most common mode for wireless networking.
■ You should know where Windows Firewall log files are stored, whether logging is
available, and what kind of information you can learn from log files.
ad-hoc wireless network A wireless network mode in which multiple wireless stations

New Connection Wizard A wizard in Windows XP Professional that can perform
much of the work of configuring a network connection for different situations.
Wi-Fi Protected Access (WPA) A wireless encryption standard available in Windows

the other encryption standard supported by Windows XP Professional.
Windows Firewall A stateful, host-based firewall provided with Windows XP
Professional.
Wired Equivalent Privacy (WEP) One of two wireless encryption standards available
in Windows XP Professional. WEP is the encryption standard that is specified
