Shared Key: with the same WEP key between the stations in this Authentication algorithm, this type will use packets with encryption by transferring a challenge text which will be acknowledge by both side of the stations. In order to choose which authentication algorithm will be used, you must know which one the station supports this algorithm first. ! Caution: WEP Key needs to be the same with the stations where you want to join. If the Link between the stations is good and the WEP key is different, you cannot process the data transmitting between the stations. After the settings are completed, click the Submit button to save the setting. Advanced The screen shows the advanced setting of the Wireless Configuration Utility, and it includes Preamble Type, Fragmentation Threshold, and RTS / CTS Threshold. The default setting of Preamble Type is Long. The usage of the preamble is to limit the packet size of the data to transmit. It is recommended to choose the short preamble when the link quality is bad, it is to prevent the wasting time of resending a long packet that is lost. 15 Fragmentation Threshold is a way of transmitting the packets that will be fragmented. Choose a setting within a range of 256 to 2346 bytes. It is recommended to fragment the packet when the link quality is bad, it is to prevent the wasting time of resending a long packet that is lost. The RTS/CTS Threshold is a station initiates the process by sending a RTS frame, the other ends receives the RTS and responds with a CTS frame, the station must receive a CTS frame before sending the data frame. This is to prevent the collisions by each station. Choose a setting within a range of 1 to 1247 bytes. It is recommend to limit a long packet to prevent each station waiting too long to transmit a data. ¾ Power Save By enabling this mode as 802.11 Power Save to set your Wireless USB Adapter as power saving mode.
