●Ad-Hoc – to establish point-to-point wireless communication directly with other 
wireless client devices. 
AdHoc Band: There are three available selection for Auto, 11b and 11g 
Channel: The channel the AP operates on. Users can select the channel range of 1 
to 11 for North America (FCC) domain and 1 to 13 for European (ETSI) and Japan 
(MKK) domains. 
Power  Mode: There are 3 modes to choose from. 
●Continuous Access Mode (default) – the 300Mbps Wireless N USB 2.0 Adapter is 
constantly operating with full power.  This mode consumes the most power. 
●Maximum Power Save – the 300Mbps Wireless N USB 2.0 Adapter consumes the 
least power. This mode only operates when there is wireless network activity. 
●Power Save – the 300Mbps Wireless N USB 2.0 Adapter consumes moderate 
level of power. 
Preamble: Select Long or Short & Long Preamble type. Preamble is a sequence of 
bits transmitted at 1Mbps that allows the PHY circuitry to reach steady-state 
demodulation and synchronization of bit clock and frame start. Two different 
preambles and headers are defined: the mandatory supported Long Preamble and 
header, which interoperates with the 1Mbps and 2Mbps DSSS specification (as 
described in IEEE 802.11), and an optional Short Preamble and header (as 
described in IEEE 802.11b). At the receiver, the Preamble and header are processed 
to aid in demodulation and delivery of the PSDU. The Short Preamble and header 
may be used to minimize overhead and, thus, maximize the network data 
throughput. However, the Short Preamble is supported only for the IEEE 802.11b 
(High- Rate) standard and not for the original IEEE 802.11 standard. That means 
that stations using Short-Preamble cannot communicate with stations implementing 
the original version of the protocol. Click “Apply” to save the changes.  
Support Band: There are 2 modes the user can select; 11B and 11G.  By default, 
11B and 11G are enabled.    
Link Speed: Select one of the wireless communications transfer rates, measured in 
megabytes per second, based upon speed of the wireless adapters connected to the 
WLAN.
