WPS
Wi-Fi Protected Setup (WPS):
WPS is a computing standard for easy
and secure setup of a wireless connection. In this section you can
enable WPS for a client connection using WPA/WPA2 security.
1. Check the box to enable WPS.
2. Click Apply to apply the changes. Or click Reset to undo your
configurations.
Push Button Connect (PBC):
If other wireless devices support the PBC
WPS function, click on Click for PBC and then push the WPS button on
the other device.
Personal Information Number (PIN):
If other wireless devices support
the PIN WPS function, specify the same PIN for the DWR-923 and the
wireless device and then click Submit PIN to establish a connection.

Wi-Fi Access Control
Access control allows you to block or allow computer devices from
establishing a wireless link to the DWR-923. The filtering is based on
the wireless computer
s unique hardware ID (MAC address). With this
feature you can prevent unknown or unauthorized computers from
accessing the DWR-923 and the services (like shares, DMC) it offers. In
most cases you know which devices will be connecting to the DWR-923
through a wireless connection, which allows you to add these known
devices to a list for authorized access. This feature helps in securing the
wireless connectivity of the home network.

Wireless Client Access Policy
Access Rule for Registered MAC Address:
Allow Everybody:
Allows all devices to connect to the DWR-923
wirelessly regardless of the list of wireless computers defined below.
Allow:
Allows devices that are added in the MAC address list to connect
to the DWR-923.
Deny:
Devices that are added in the MAC address list will be blocked
when trying to connect to the DWR-923.
Click Apply to apply the changes. Or click Reset to undo your
configurations.
List of MAC Addresses:
This is the list of wireless devices that have
been added for the ACL policy.
MAC Address:
The unique hardware ID of the local network wireless
computer.

Wi-Fi Advanced
This section allows you to configure and manage advanced settings of
your wireless network. In most cases, however, the default wireless
settings will be sufficient.
Disable Network Name Broadcast:
By disabling SSID broadcasting, the
DWR-923 will not broadcast its Network ID (SSID) to announce itself to
wireless stations and other access points.
Group Re-Key Interval:
Specify the timeout interval after which group
keys are generated (only used if profile is configured with WPA or
WPA2 security).

Beacon Interval:
Enter the time in milliseconds between beacon
transmissions. The default interval is 100 milliseconds.
Fragmentation Threshold:
This is the maximum length of the frame, in
bytes, beyond which packets must be broken up (fragmented) into two
or more frames. Collisions occur more often for long frames because
while sending them they occupy the channel for a longer time. The
default value is 2346, which effectively disables fragmentation.
RTS Threshold:
The Request to Send (RTS) threshold is the packet size
in bytes above which the DWR-923 is required to check the
transmitting frames to determine if RTS/Clear to Send (CTS) handshake
is required with the receiving client. Using a small value causes RTS
packets to be sent more often, consuming more of the available
bandwidth, therefore reducing the apparent throughput of the
network packets. The default value is 2346, which effectively disables
RTS.
Transmit Power:
Enter a value in dBm for the default transmit power
level.
Channel:
The wireless channel that the DWR-923 will broadcast on.
This specifies the radio frequency used to transmit wireless frames.
Select a channel from the list or choose Auto to let the system
determine the best channel to use based on environmental noise levels
for all available channels.
Wireless Mode:
Select the 802.11 modulation technique. The
DWR-923 supports 802.11 b/g/n Wi-Fi modes.
Bandwidth:
When you choose
ng
as your wireless mode, you may
choose a Wi-Fi bandwidth for this product from HT20, HT40- and
HT40+. Higher bandwidth indicates a higher throughput of your
