Chapter 4 Troubleshooting 

This chapter provides solutions to problems usually encountered during the 

installation

 and operation of 

the 

Wireless Broadband Router

. Read the description below to solve your problems. 

4.1 Frequently Asked Questions 

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. 

 

What IEEE 802.11 features are supported? 

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 

 

What is PBCC?   

This new products use the ACX100 chip from Texas Instruments. In addition to meeting the existing 

standard, the chip also supports a new modulation scheme developed by TI, called Packet Binary 

Convolution Code (PBCC). It's this scheme that gives the products the extra kick: Even at lower 

speeds, PBCC provides better performance at greater distances, and it can also work at 22 Mbps.

 

 

What is Ad-hoc? 

An Ad-hoc integrated wireless LAN is a group of computers, each with a WLAN adapter, connected 

as an independent wireless LAN. Ad hoc wireless LAN is applicable at a departmental scale for a 

branch or SOHO operation.
