Section 3 - Configuration
CTS Mode:
CTS (Clear To Send) is a function used to minimize collisions
among wireless devices on a wireless local area network
(LAN). CTS will make sure the wireless network is clear before
a wireless client attempts to send wireless data. Enabling
CTS will add overhead and may lower wireless throughput.
None: CTS is typically used in a pure 802.11g environment. If
CTS is set to "None" in a mixed mode environment populated
by 802.11b clients, wireless collisions may occur frequently.
Always:. CTS will always be used to make sure the
w i r e l e s s L A N i s c l e a r b e f o r e s e n d i n g d a t a .
Auto: CTS will monitor the wireless network and
automatically decide whether to implement CTS based
on the amount of traffic and collisions that occurs on the
wireless network.

Auto 20/40 MHz - Select if you are using both 802.11n and
non-802.11n wireless devices.
20 MHz - Select if you are not using any 802.11n wireless
clients.
STBC: Enable or disable Space-time block code.
20/40 MHz Enable or disable 20/40 MHz Coexistence.
Coexist:
Short GI: Check this box to reduce the guard interval time therefore
increasing the data capacity. However, it's less reliable and
may cause more data loss.
