NOTE: The access point also allows you to disable SNTP and set the system clock
manually.
Set Time Zone – SNTP uses Coordinated Universal Time (or UTC, formerly
Greenwich Mean Time, or GMT) based on the time at the Earth's prime meridian,
zero degrees longitude. To display a time corresponding to your local time, you
must indicate the number of hours your time zone is located before (east) or after
(west) UTC.
Enable Daylight Saving – The access point provides a way to automatically adjust
the system clock for Daylight Savings Time changes. To use this feature you must
define the month and date to begin and to end the change from standard time.
During this period the system clock is set back by one hour.

The IEEE 802.11a and 802.11g interfaces include configuration options for radio
signal characteristics and wireless security features. The configuration options are
nearly identical, and are therefore both covered in this section of the manual.
The access point can operate in three modes, IEEE 802.11a only, 802.11b/g only,
or a mixed 802.11a/b/g mode. Also note that 802.11g is backward compatible
with 802.11b. These interfaces are configured independently under the following
web pages:
Each radio supports up to four virtual access point (VAP) interfaces numbered 1to
4. Each VAP functions as a separate access point, and can be configured with its
own Service Set Identification (SSID) and security settings. However, most radio
signal parameters apply to all four VAP interfaces.
The VAPs function similar to a VLAN, with each VAP mapped to its own VLAN ID.
Traffic to specific VAPs can be segregated based on user groups or application
traffic.
Secondary Server: The IP address of a secondary SNTP or NTP time server. The
access point first attempts to update the time from the primary server; if this
fails it attempts an update from the secondary server.
