•40MHz – Click to allow 802.11n clients that support the 40MHz
frequency to use 40MHz, 20MHz, or the 802.11a radio protocols.
802.11n clients that do not support the 40MHz frequency can use
20MHz or the 802.11a radio protocols and non-802.11n clients,
beacons, and multicasts use the 802.11a radio protocols.
•Auto – Click to automatically switch between 20MHz and 40MHz
channel widths, depending on how busy the extension channel is.
• 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 to minimize broadcast and multicast
delay. The default value is 5.
• 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 Wireless 802.11n AP prior to
transmission. The default value is 2346, which means all packets are sent
unfragmented. Reduce this value only if necessary.
11. In the Basic Radio Settings section, do the following:
• Request New Channel – Click the wireless channel you want the
Wireless 802.11n AP to use to communicate with wireless devices.
Click Auto to request the ACS to search for a new channel for the
Wireless AP, using a channel selection algorithm. This forces the
Wireless 802.11n AP to go through the auto-channel selection process
again.
Depending on the regulatory domain (based on country), some channels
may be restricted. The default value is based on North America. For more
information, see Appendix B, “Regulatory information”.
• Guard Interval – Click a guard interval, Long or Short, when a 40MHz
channel is used. It is recommended to use a short guard interval in small
rooms (for example, a small office space) and a long guard interval in
large rooms (for example, a conference hall).
•Max Tx Power – Click the maximum Tx power level that the range of
transmit power can be adjusted: 0 to 22 dBm. It is recommended to use
22 dBm to not limit the potential Tx power level range that can be used.
