Configuring the Wireless AP
If applicable, click the 802.11a tab to modify the radio properties.
●
DTIM Period – Type the desired DTIM (Delivery Traffic Indication Message) period—the number
●
of beacon intervals between two DTIM beacons. To ensure the best client power savings, use a
large number. For example, 5. Use a small number for broadcast and multicast delay. The default
value is 1.
Beacon Period – Type the desired time, in milliseconds, between beacon transmissions. The
●
default value is 100 milliseconds.
RTS/CTS Threshold – Type the packet size threshold, in bytes, above which the packet will be
●
preceded by an RTS/CTS (Request to Send/Clear to Send) handshake. The default value is 2346,
which means all packets are sent without RTS/CTS. Reduce this value only if necessary.
Frag. Threshold – Type the fragment size threshold, in bytes, above which the packets will be
●
fragmented by the AP prior to transmission. The default value is 2346, which means all packets
are sent unfragmented. Reduce this value only if necessary.
802.11a – Select to enable the 802.11a radio.
●
Channel – Select the wireless channel that the Wireless AP will use to communicate with wireless
●
devices. Depending on the regulatory domain (based on country), some channels may be
restricted. The default value is based on North America. The Auto selection allows the Wireless
AP to select the appropriate channel automatically. For more information, see
B, "Regulatory Information."
If DRM is enabled (DRM is enabled by default), it scans automatically for a channel, using a
channel selection algorithm. For more information, see
Management" on page
Tx Power Level – For each radio, select the appropriate Tx power level from the Max TX Power
●
Level drop-down menu. The values in the Max TX Power Level drop down is in dBm (dBm is an
abbreviation for the power ratio in decibel (dB) of the measured power referenced to one
