PSK2
. PSK2 is stronger than WPA Personal and gives you one encryption method, AES, with dynamic encryption
keys. Enter a Passphrase of 8-63 characters. Then enter a Key Renewal period, which instructs the Router how
often it should change the encryption keys.
PSK2-Mixed
. PSK2-Mixed gives you either WPA-Personal (TKIP) or PSK2 (AES) encryption. Enter a Passphrase of
8-63 characters. Then enter a Key Renewal period, which instructs the Router how often it should change the
encryption keys.
WPA Enterprise
. This option features WPA used in coordination with a RADIUS server. (This should only be used
when a RADIUS server is connected to the Router.) First, select the type of WPA encryption you want to use,
TKIP
or
AES
. Enter the RADIUS server’s IP Address and port number, along with a shared secret (authentication key)
between the Router and the server. Last, enter a Key Renewal Timeout, which instructs the Router how often it
should change the encryption keys.

PSK2 + RADIUS
. This option features a PSK2 used in coordination with a RADIUS server. (This should only be
used when a RADIUS server is connected to the Router.) AES
is the type of encryption method used. Enter the
RADIUS server’s IP address and port number, along with the shared secret (authentication key) shared by the
Router and the server. Last, enter the Key Renewal period, which instructs the Router how often it should change
the encryption keys.
RADIUS
. This option features WEP used in coordination with a RADIUS server. (This should only be used when a
RADIUS server is connected to the Router.) First, enter the RADIUS server’s IP Address and port number, along
with a shared secret (authentic key) shared between the Router and the server. Then, select a level of WEP
encryption,
40/64 bits 10 hex digits
or
104/128 bits 26 hex digits
and either generate a WEP key using the
Passphrase or enter the WEP key manually, and lastly, select a Default Transmit Key (choose which Key to use).

The Wireless Tab - Wireless MAC Filter
Wireless access can be filtered by using the MAC addresses of the wireless devices transmitting within your
network’s radius.
Wireless MAC Filter
To filter wireless users by MAC Address, either permitting or blocking access, click
Enabled
. If you do not wish to
filter users by MAC Address, select
Disabled
.
Access Restriction
Prevent PCs listed below from accessing the wireless network
. Clicking this button will block wireless
access by MAC Address.
Permit PCs listed below to access the wireless network
. Clicking this button will allow wireless access by
MAC Address.
MAC Address Filter List
You can manually enter a MAC address to filter or you can select one from the Wireless Client List.
Wireless Client List
. Click the
Wireless Client MAC List
button to display a list of wireless network users. From
the
To Sort by
drop-down menu, you can sort the table by Client Name, IP Address, MAC Address, Interface, or
Client Name. To add a client’s MAC Address to your MAC Address Filter list, click the
Save to MAC Address Filter

Wireless-G Broadband Router with RangeBooster
The Wireless Tab - Advanced Wireless Settings
This tab is used to set up the Router’s advanced wireless functions. These settings should only be adjusted by an
expert administrator as incorrect settings can reduce wireless performance.
Advanced Wireless
Frame Burst Mode
. Enabling this option should provide your network with greater performance, depending on
the manufacturer of your wireless products. The default setting is
Enabled
.
AP Isolation
. This isolates all wireless clients and wireless devices on your network from each other. Wireless
devices will be able to communicate with the Router but not with each other. To use this function, click
Enabled
.
AP Isolation is disabled by default.
Authentication Type
. The default is set to
Auto
, which allows either Open System or Shared Key authentication
to be used. With
Open System
authentication, the sender and the recipient do NOT use a WEP key for
authentication. With
Shared Key
authentication, the sender and recipient use a WEP key for authentication.
Basic Rate
. The Basic Rate setting is not actually one rate of transmission but a series of rates at which the
Router can transmit. The Router will advertise its Basic Rate to the other wireless devices in your network, so
they know which rates will be used. The Router will also advertise that it will automatically select the best rate
for transmission. The default setting is
Default
, when the Router can transmit at all standard wireless rates
(1-2Mbps, 5.5Mbps, 11Mbps, 18Mbps, and 24Mbps). Other options are
1-2Mbps
, for use with older wireless
technology, and
All
, when the Router can transmit at all wireless rates. The Basic Rate is not the actual rate of
data transmission. If you want to specify the Router’s rate of data transmission, configure the Transmission Rate
setting.
Transmission Rate
. The rate of data transmission should be set depending on the speed of your wireless
network. You can select from a range of transmission speeds, or you can select
Auto
to have the Router
automatically use the fastest possible data rate and enable the Auto-Fallback feature. Auto-Fallback will
negotiate the best possible connection speed between the Router and a wireless client. The default setting is
Auto.
Transmission Power
. The greater the transmission power used, the larger the area a wireless network covers.
To minimize the likelihood of eavesdropping by unauthorized wireless users, do not use more transmission power
than necessary to cover the range needed by your wireless network. Try using the Router at different levels of
transmission power, and determine how much power is needed to reach the wireless client, such as a PC or
access point, that is farthest from the Router. Then select the appropriate level,
Full
,
Half
,
Quarter
,
Eighth
, or
Min
, from the drop-down menu. The default setting is
Full
.

CTS Protection Mode
. CTS (Clear-To-Send) Protection Mode’s default setting is
Auto
. The Router will
automatically use CTS Protection Mode when your Wireless-G products are experiencing severe problems and
are not able to transmit to the Router in an environment with heavy 802.11b traffic. This function boosts the
Router’s ability to catch all Wireless-G transmissions but will severely decrease performance.
Beacon Interval
. The Beacon Interval value indicates the frequency interval of the beacon. A beacon is a packet
broadcast by the Router to synchronize the wireless network. The default value is
100
.
DTIM Interval
. This value indicates the interval of the Delivery Traffic Indication Message (DTIM). A DTIM field is
a countdown field informing clients of the next window for listening to broadcast and multicast messages. When
the Router has buffered broadcast or multicast messages for associated clients, it sends the next DTIM with a
DTIM Interval value. Its clients hear the beacons and awaken to receive the broadcast and multicast messages.
The default value is
1
.
Fragmentation Threshold
. This value specifies the maximum size for a packet before data is fragmented into
multiple packets. If you experience a high packet error rate, you may slightly increase the Fragmentation
Threshold. Setting the Fragmentation Threshold too low may result in poor network performance. Only minor
reduction of the default value is recommended. The default value is
2346
.
RTS Threshold
. Should you encounter inconsistent data flow, only minor reduction of the default value,
2346
, is
recommended. If a network packet is smaller than the preset RTS threshold size, the RTS/CTS mechanism will
not be enabled. The Router sends Request to Send (RTS) frames to a particular receiving station and negotiates
the sending of a data frame. After receiving an RTS, the wireless station responds with a Clear to Send (CTS)
frame to acknowledge the right to begin transmission. The default value is
2346
.
