to set these data rates to

on the 802.11g, 2.4-GHz radio.
Note
If the client must support the basic rate that you select, it cannot
associate to the wireless device. If you select 12-Mb/s or higher for
the basic data rate on the 802.11g radio, 802.11b client devices cannot
associate to the wireless device 802.11g radio.

,
basic-24.0
,

•
(Optional) Enter
range
or
throughput
or
ofdm-throughput
(no ERP
protection) to automatically optimize radio range or throughput. When
you enter
range
,
the wireless device sets the lowest data rate to
basic
and
sets the other rates to
enabled
. When you enter
throughput
, the wireless
device sets all data rates to
basic
.
(Optional) On the 802.11g radio, enter
speed
throughput ofdm
to set all
OFDM rates (6, 9, 12, 18, 24, 36, and 48) to
basic
(
required
) and to set
all the CCK rates (1, 2, 5.5, and 11) to
disabled
. This setting disables
802.11b protection mechanisms and provides maximum throughput for
802.11g clients. However, it prevents 802.11b clients from associating to
the access point.
•
(Optional) Enter
default
to set the data rates to factory default settings
(not supported on 802.11b radios).
On the 802.11g radio, the
default
option sets rates 1, 2, 5.5, and 11 to
basic
, and sets rates 6, 9, 12, 18, 24, 36, 48, and 54 to
enabled
. These rate
settings allow both 802.11b and 802.11g client devices to associate to the
wireless device 802.11g radio.
On the 5-GHz radio, the
default
option sets rates 6.0, 12.0, and 24.0 to
basic
, and sets rates 9.0, 18.0, 36.0, 48.0, and 54.0 to
enabled
.
On the 802.11g/n 2.4-GHz radio, the
default
option sets rates 1.0, 2.0,
5.5, and 11.0 to
enabled
.
On the 802.11g/n 5-GHz radio, the
default
option sets rates to 6.0, 12.0,
and 24.0 to
enabled
.
The modulation coding scheme (MCS) index range for both 802.11g/n
radios is 0 to 15.
