5.1 Frequently Asked Questions

What is WPA (Wi-Fi Protected Access)?

WPA resolves the issue of weak WEP headers, which are called initialization vectors (IV), and

provides a way of insuring the integrity of the messages passed through MIC (called Michael or

message integrity check) using TKIP (the Temporal Key Integrity Protocol) to enhance data

encryption. WPA-PSK is a special mode of WPA for home users without an enterprise

authentication server and provides the same strong encryption protection. WPA is not an official

IEEE standard, but is based on and is expected to be compatible with the upcoming 802.11i

security standard

Can I run an application from a remote computer over the wireless network?

This will depend on whether or not the application is designed to be used over a network. Consult

the application

’

s user guide to determine if it supports operation over a network.

Can I play games with other members of the wireless network?

Yes, as long as the game supports multiple plays over a LAN (local area network). Refer to the

game

’

s user guide for more information.

What is the IEEE 802.11b standard?

The IEEE 802.11b Wireless LAN standards subcommittee, which is formulating a standard for the

industry. The objective is to enable wireless LAN hardware from different manufactures to

communicate.
