• Protection Type
This option is only relevant when the Protection Mode is on. The options
here are CTS-only or RTS-CTS. With CTS-only, the client is not required
to send an RTS (Request-to-Send) to the AP. As long as the client receives
a CTS (Clear-to-Send) frame from the AP then the client is free to send
data. With the RTS-CTS option enabled, the client is required to send an
RTS to the AP and wait for a CTS from the AP before it can send data (this
option creates additional overhead and can cause performance
degradation). The default is CTS-only.
• Short Slot Time
802.11g defines the long slot time as 20 microseconds and a short slot
time as 9 microseconds. 802.11b only supports the long slot time of 20
microseconds. In an environment with 802.11g devices only, this option
(Short Slot Time) must be enabled for better performance—giving
precedence to 802.11g traffic. Only disable this option in mixed
(802.11b and 802.11g) environments. The default is enabled.
• Short Preamble
Short slot preamble improves network efficiency by reducing the
preamble from 128 bits to 56 bits. 802.11g is required to support both
short and long preambles (802.11b support for a short preamble is
optional). If this option is enabled, any 802.11b clients associated with
the network must support a short preamble. The default for this option is
enabled.
After inputting data (or making selections), click on the Update button to update this

the network. If necessary, you can click on the factory default (FD) button in the
toolbar to reset all data on this page to its factory default state.
