types (B, G and N) at the same time from a single 2.4GHz
radio. 802.11n transmission is always embedded in an
802.11a, for 5GHz radios, or 802.11g for 2.4GHz radio
transmissions. This is called Mixed Mode Format
protection (also known as L-SIG TXOP Protection).
Preamble
Values include
Long
and
Short
, and the default value is
Long
. If your wireless device supports the short
preamble and you are having trouble getting it to
communicate with other 802.11b devices, make sure that
it is set to use the long preamble
