2.  Enable 'Wireless Protection’ in ‘Advanced’ tab. 

3.  Disable Tx Burst' in ‘Advanced’ tab. 

4.  Enable ‘WMM’ in ‘QoS’ tab if you 

need to use multimedia / telephony related applications. 

5.  Disable ‘WMM - Power Save Enable’ in ‘QoS’ tab. 

6.  There could be too many people using the same radio channel. Ask

4.5 Glossary 

1.  What is the IEEE 802.11g standard? 

802.11g is the new IEEE standard for high-speed wireless LAN communications that provides for 

up to 54 Mbps data rate in the 2.4 GHz band. 802.11g is quickly becoming the next mainstream 

wireless LAN technology for the home, office and public networks. 

802.11g defines the use of the same OFDM modulation technique specified in IEEE 802.11a for 

the 5 GHz frequency band and applies it in the same 2.4 GHz frequency band as IEEE 802.11b. 

The 802.11g standard requires backward compatibility with 802.11b. 

The standard specifically calls for: 

A.  A new physical layer for the 802.11 Medium Access Control (MAC) in the 2.4 GHz frequency 

band, known as the extended rate PHY (ERP). The ERP adds OFDM as a mandatory new 

coding scheme for 6, 12 and 24 Mbps (mandatory speeds), and 18, 36, 48 and 54 Mbps 

(optional speeds). The ERP includes the modulation schemes found in 802.11b including CCK 

for 11 and 5.5 Mbps and Barker code modulation for 2 and 1 Mbps. 

B.  A protection mechanism called RTS/CTS that governs how 802.11g devices and 802.11b 

devices interoperate. 

2.  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.
