CHANGING RADIO SETTINGS
To change radio settings on a VAP, select a VAP from the list to display its current
configuration.
When you are finished configuring items on this page, click Apply.
Country Code—Displays the country where this access point is installed and
running.
Description—Enter a description for this access point.
Turbo Mode (802.11g and 802.11a only)—Turbo Mode is an enhanced
wireless LAN operating mode that can provide a higher data rate.
In normal mode the channel bandwidth is 20 MHz. In Turbo Mode the
channel bandwidth is increased to 40 MHz. However, only a limited number
of channels are available when Turbo Mode is enabled.
Auto Channel Select (802.11g only)—Select Auto Channel Select Enable to
allow the access point to select a radio channel automatically.
Radio Channel—From the pull-down list, select the radio channel over which
the access point communicates to computers in its BSS. Available channel
settings are limited by local regulations that determine which channels are
allowed. The client channel for wireless users is automatically set to that used
by the access point to which they are linked.
When multiple access points are deployed in the same area, be sure to choose
channels separated by at least five channels to avoid channel interference. You
can deploy up to three access points in the same area; for example, Ch1, Ch6,
and Ch11.
Output Antenna—Select the antenna to use on the access point. The
access
point has two antenna connectors for each radio. For the 802.11g
radio, the A
antenna is near the Ethernet connector and the B antenna is near
the LEDs.
Transmission Power (802.11g only)—Set the signal strength transmitted
from the access point. The longer the transmission distance, the higher the
transmission power required. (Default: 100%)
Maximum Transmit Data Rate—Select the appropriate data rate from the
drop-down list for the data transfer speed running on your network. (802.11b
default: 11 Mbps.) In order to reach all clients, this rate should be set lower
(for example, 1 or 2 Mbps on an 802.11b radio). To isolate clients that are
unable to connect at higher rates, set this value higher.
