Wireless Mode 

The wireless Mode supports three options 802.11B, 802.11B/G, and 802.11B/G/N. 

Power Saving Mode 

The Power Save option is designed to conserve battery life of you computer. When Power Save 

is enabled, your IEEE 802.11n Wireless LAN USB Adapter will go into sleep mode to minimize 

power consumption. 

Note:

 When power saving mode is enabled, the Access Points you use need to 

support power saving as well so that the communication can be established.

 

RTS Threshold 

RTS Threshold is a mechanism implemented to prevent the “Hidden Node” problem. If the 

“Hidden Node” problem is an issue, please specify the packet size. 

The RTS mechanism will be 

activated if the data size exceeds the value you set.

 It is highly recommended that you set the 

value ranging from 0 to 2347. The default value is 

Disable

. 

 

Note:

 Enabling RTS Threshold would cause redundant network overhead that could 

negatively affect the throughput performance instead of providing a remedy. 

 

Frag. Threshold

 

Fragmentation mechanism is used for improving the efficiency when high traffic flows along in
