4 Troubleshooting
This chapter provides solutions to problems usually encountered during the installation and
operation of the card.
1. What is the IEEE 802.11b standard
The IEEE 802.11b Wireless LAN standard subcommittee which formulates the
standard for the industry. The objective is to enable wireless LAN hardware from
different manufactures to communicate.
2. What does IEEE 802.11 feature support

O CSMA/CA plus Acknowledge Protocol
O Multi-Channel Roaming
O Automatic Rate Selection
O RTS/CTS Feature

configuration. Infrastructure is applicable to enterprise scale for wireless access to
central database, or wireless application for mobile workers.
5. What is BSS ID
A specific Ad hoc LAN is called a Basic Service Set (BSS). Computers in a BSS must
be configured with the same BSS ID.
6. What is WEP
WEP is Wired Equivalent Privacy, a data privacy mechanism based on a 40 bit shared
key algorithm, as described in the IEEE 802 .11 standard.
7. What is TKIP?
TKIP is a quick-fix method to quickly overcome the inherent weaknesses in WEP
security, especially the reuse of encryption keys. TKIP is involved in the IEEE 802.11i
WLAN security standard, and the specification might be officially released by early
2003.
