for more than one PC/Laptop, you need to purchase additional license keys by calling our
Broadband Team.

can use it. This protocol was created in response to several serious weaknesses researchers
had found in the previous system, Wired Equivalent Privacy (WEP).

35. What is WPA2?
Wi‐Fi Protected Access 2 (WPA2) is a product certification available through the Wi‐Fi Alliance
that certifies wireless equipment as being compatible with the 802.11i standard. The goal of
WPA2 certification is to support the additional mandatory security features of the 802.11i
standard that are not already included for products that support WPA.

37. What is wireless auto configuration?
Wireless auto configuration is the feature of Windows Vista, Windows Server 2008, Windows
XP, and Windows Server 2003 that allows Windows to detect the available wireless networks
and automatically connect to the preferred wireless network. Wireless auto configuration is
enabled by the Wireless Zero Configuration service in Windows XP, the Wireless Configuration
service in Windows Server 2003, and the WLAN AutoConfig service in Windows Vista and
Windows Server 2008.

38. What does it mean when Windows shows that I am connected to the wireless network?
When Windows XP has no service packs installed, Windows XP with Service Pack 1, and
Windows Server 2003 displays a connected state, it means that you have created an
association with a wireless Access Point. The association is the result of a negotiation with the
wireless Access Point to use one of its available connections. However, a successful wireless
connection also needs to perform an authentication process, determine encryption keys, and
obtain an Internet Protocol (IP) address using the Dynamic Host Configuration Protocol
(DHCP). When Windows XP with Service Pack 2 or Windows Server 2003 with Service Pack 1
displays a connected state, the wireless client computer has associated, authenticated, and
received a valid IP address configuration.
