4 Troubleshooting 

 
This chapter provides solutions to problems usually encountered during the installation and 
operation of the adapter.  
 

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

 

The product supports the following IEEE 802.11 functions: 

 

CSMA/CA plus Acknowledge Protocol 

 

Multi-Channel Roaming 

 

Automatic Rate Selection 

 

RTS/CTS Feature 

 

Fragmentation 

 

Power Management 

 

3.  What is Ad-hoc

 

An Ad-hoc integrated wireless LAN is a group of computers, each has a Wireless LAN 
adapter, Connected as an independent wireless LAN. Ad hoc wireless LAN is 
applicable at a departmental scale for a branch or SOHO operation. 
 

4.  What is Infrastructure

 

An integrated wireless and wireless and wired LAN is called an Infrastructure 
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.
