The Advanced Setting page allows you to configure the more advanced radio 
settings, many of which are enabled by default.

Click “Wireless Settings” followed by “Advanced Setting.”

• b/g Protection – Enables a backward 

compatible protection system for 
802.11b clients. There are three modes. 
(Default: Auto): 
- Auto: The wireless AP/Router enables its protection mechanism for 802.11b 

clients when they are detected in the network. When 802.11b clients are not 
detected, the protection mechanism is disabled.

- Always On: Forces the unit to always use protection for 802.11b clients, 

whether they are detected in the network or not.

- Always Off: Forces the unit to never use protection for 802.11b clients. This 

prevents 802.11b clients from connecting to the network.

Note: Enabling “Always On” b/g Protection can slow throughput for 802.11g/n clients by 

as much as 50%. 

• HT Operation Mode – Packets from 

802.11n clients are referred to as High 
Throughput (HT) Greenfield packets, in 
other words packets that can be transmitted at rates of up to 300 Mbps assuming 
that HT Channel Bandwidth is set to 20/40Mhz, see HT Channel Bandwidth next 
page. 

Note: Some 802.11n wireless clients may be capable of transmission rates of up to 

600 Mbps, however the wireless AP/Router will only be able to connect to them at 
a maximum transmission rate of 300 Mbps.
