Set each data rate to basic or enabled, or enter range to
optimize range or throughput to optimize throughput.
•(Optional) Enter basic-1.0, basic-2.0, basic-5.5,
basic-6.0, basic-9.0, basic-11.0, basic-12.0, basic-18.0,
basic-24.0, basic-36.0, basic-48.0, and basic-54.0 to set
these data rates to basic on the 802.11g, 2.4-GHz radio.
Note The client must support the basic rate that you select or
it cannot associate to the wireless device. If you select
12 Mbps 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.
Enter basic-6.0, basic-9.0, basic-12.0, basic-18.0,
basic-24.0, basic-36.0, basic-48.0, and basic-54.0 to set
these data rates to basic on the 5-GHz radio.
(Optional) Alternatively, 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 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 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 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 rates 9.0, 18.0, 36.0, 48.0, and 54.0
to enabled.
