• Country – Click the country of operation. This option is only available with
some licenses.
12. In the Radio Settings section, do the following:
• Radio Mode – Click the radios you want to enable.
• Channel Width – Click the channel width for the radio:
•20MHz – Click to allow 802.11n clients to use the primary channel
(20MHz) and non-802.11n clients, beacons, and multicasts to use the
802.11b/g radio protocols.
•40MHz – Click to allow 802.11n clients that support the 40MHz
frequency to use 40MHz, 20MHz, or the 802.11b/g radio protocols.
802.11n clients that do not support the 40MHz frequency can use
20MHz or the 802.11b/g radio protocols and non-802.11n clients,
beacons, and multicasts use the 802.11b/g radio protocols.
•Auto – Click to automatically switch between 20MHz and 40MHz
channel widths, depending on how busy the extension channel is.
•DTIM – 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 – For each radio, type the desired time, in milliseconds,
between beacon transmissions. The default value is 100 milliseconds.
• RTS/CTS – For each radio, 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 – For each radio, 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.
• Channel – For each radio, click the wireless channel you want the
Wireless APs to use to communicate with wireless devices.
Click Auto to request the ACS to search for a new channel for the
Wireless APs, using a channel selection algorithm. This forces the APs to
go through the auto-channel selection process again.
If DRM is enabled (DRM is enabled by default), it scans automatically for
a channel, using a channel selection algorithm.
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”.
