3G9W - HSPA 7.2Mbps Wi-Fi Router USER GUIDE
YML902 – 31
Option Description
54g Mode
Select Auto mode for greatest compatibility. Select Performance mode for the fastest
performance among 54g certified equipment. Select LRS mode if you are experiencing
difficulty with legacy 802.11b equipment. If this does not work, you may also try
802.11b only mode.
54g Protection
In Auto mode, the router will use RTS/CTS to improve 802.11g performance in mixed
802.11g/802.11b networks. Turning protection Off will maximize 802.11g throughput
under most conditions.
Preamble Type Short preamble is intended for applications where maximum throughput is desired but
it does not work with legacy equipment. Long preamble works with the current 1 and 2
Mbit/s DSSS specification as described in IEEE Std 802.11-1999
Transmit Power
Set the power output (by percentage) as desired.
