Problems with Date and Time
The E-Mail menu in the Content Filtering section displays the current date and time of day. The
WPN824 router uses the Network Time Protocol (NTP) to obtain the current time from one of
several Network Time Servers on the Internet. Each entry in the log is stamped with the date and
time of day. Problems with the date and time function can include:
Date shown is January 1, 2000. Cause: The router has not yet successfully reached a Network
Time Server. Check that your Internet access settings are configured correctly. If you have just
completed configuring the router, wait at least five minutes and check the date and time again.
Time is off by one hour. Cause: The router does not automatically sense Daylight Savings
Time. In the E-Mail menu, check or uncheck the box marked “Adjust for Daylight Savings
Time”.

Warning
: The Wireless Router is already configured with the optimum settings. Do not alter these
settings unless directed by NETGEAR support. Incorrect settings may disable the Wireless Router
unexpectedly.
Program the advanced wireless settings as follows:
Enable Wireless Router Radio
—The Wireless Access Point Router of this router can be
enabled or disabled to allow wireless access. The wireless icon on the front of the router will
also display the current status of the Wireless Access Point to let you know if it is disabled or
enabled. If Enabled, wireless stations will be able to access the Internet. If Disabled, wireless
stations will not be able to access the Internet.
Enable SSID Broadcast
—If Enabled, the Wireless Router SSID will broadcast its name
(SSID) to all Wireless Stations. Stations which have no SSID (or a "null" value) can then adopt
the correct SSID for connections to this Access Point.
Fragmentation Threshold, CTS/RTS Threshold, Preamble Mode
—These settings are
reserved for wireless testing and advanced configuration only. Do not change these settings.
108Mbps Settings
Disable Advanced 108Mbps Features
—If Disabled, the Wireless Router will disable
data compression, packet bursting and large frame support.
Enable Adaptive Radio
—The Adaptive Radio (AR) feature is an option that is available
when the wireless settings is switched to the Dynamic 108 mode. When the Adaptive
Radio feature is set to "Enable", the Dynamic 108 mode will rate down automatically to
the standard 802.11g (11g or 11b) mode and operate at 54Mbps date rate or below when it
senses any other neighboring wireless networks that is using an adjacent wireless channel.
It will step up to a maximum data rate of 108Mbps when it senses that no other
neighboring wireless networks are using adjacent channels. As the NETGEAR 108Mbps
Wireless Products provide minimum interference to neighboring networks, the default
setting for the Adaptive Radio feature is set to "Disable".
Enable eXtended Range
—Enable eXtended Range - eXtended Range (XR) Technology
provides significantly longer range than basic 802.11 by maintaining connectivity when
signals are made faint when passing through dense walls, floors, or other barriers. XR
products require no additional configuration by end-users and are fully interoperable with
standard 802.11 technologies.
Wireless Card Access List
—By default, any wireless PC that is configured with the correct
SSID will be allowed access to your wireless network. For increased security, you can restrict
access to the wireless network to only allow specific PCs based on their MAC addresses.
