Preamble Mode, RTS Threshold and Frag Threshold?
This link provides in depth info about Preamble modes, but to summarise, Short mode is better for faster throughput: UNINETT: WLAN – Throughput Frag threshold: On extremely poor links with lots of lost packets, set a small frag threshold and only the trashed fragment has to be retransmitted. But there’s overhead for each packet, so on a “normal” net you leave the frag threshold at the maximum value, which is the default. RTS threshold: On a heavily loaded net with lots of collisions, you can use a RTS/CTS extension, which avoids collisions at the cost of an extra administrative packet for each data packet. So you only want to do this for big packets. Many cards are not capable of doing RTS/CTS anyway.
