Wireless Setup WPA PSK Option (Advanced Home Networking)
WPA security changes encryption keys after a specified amount of time.
This is the
most secure option
for wireless networks.
This section assumes you currently have the “Wireless Security Configuration”
window displayed on your computer.
To use the WPA option:
1.
Select the WEP 64-bits option from the “Security Mode” drop-down.
2.
Optionally
, select the “Enable SSID Broadcast” option if you wish if you wish for wireless users to
see the existence of your wireless router with the associated SSID. This could cause a security
problem if outside users can determine your channel and encryption. Disabling the SSID broadcast
prevents outside users from seeing the existence of your wireless router.

The “Wireless WPA Configuration” window is used to configure the algorithm, shared key, and key
renewal options.
Select one of the following options from the “Algorithms” drop-down:
•
TKIP
: (Temporal Key Integrity Protocol) TKIP is a more powerful security protocol than WEP
and supports: Verification of the security configuration after the encryption keys are determined,
synchronizes changing of the unicast encryption key for each frame, and the determines a unique
starting unicast encryption key for each pre-shared key authentication.
•
AES
: (Advanced Encryption Standard) AES supports a private key algorithm that ranges from
128 to 256 bits.

Type a key in the “Shared Key” box.
The shared key is used to generate a dynamic encryption key
for gateway security.
6.
Type a numeric value (in seconds) of the time lapse in changing the key in the “Group Key Renewal”
box and click
Next
.
Note
:
The minimum time value is 30.

Wireless Filter and Options Configuration
The “Wireless Filter Configuration” window allows you to either permit or deny access to the gateway of
wireless devices based on the MAC address of the device.
A MAC (Media Access Control) address
refers to a hardware address that uniquely identifies each device of a network.
Note
: Please see the user
documentation for each device you wish to deny or allow access for a particular MAC address.
Figure 62.
Wireless Filter Configuration Window
To use the wireless filter configuration:
1.
Select the “Enable” option to either allow or deny access to the gateway.
Note
: If you select the
“Disable” option, all devices have access to the gateway.
2.
If the “Enable” option was selected in step 1, click the “Allow” or “Deny” option next to the “Filter
Mode” heading.
The “Allow” option allows all of the MAC addresses entered in the table below
access to the gateway.
The “Deny” option denies all of the MAC addresses entered in the table below
access to the gateway.
3.
Type the MAC address in the “MAC Address” column of each device in which you either want to
allow or restrict access.

The system responds with the “Wireless Options Configuration” window.

Wireless Options Configuration Window

Optionally, configure the following items:
•
Data Transfer Rate
If a particular wireless client is unable to auto-negotiate a connection to the Gateway, the data
transfer rate may be set to a specific data rate such as 11 Mbps for 802.11b wireless clients.
•
RTS/CTS Threshold
A combination of wireless clients may experience difficulty allowing each other to communicate
with the Gateway without interrupting each other’s communications. If this occurs, the RTS/CTS
threshold may be set to a higher number to allow them each a longer period in which to
communicate with the Gateway before the priority is switched to another wireless client wishing
to transmit data.
•
Fragmentation Threshold
The fragmentation threshold may be lowered to improve reliability in an excessively “noisy”
wireless environment where changing channels does not provide significant enough improvement.
Note
: If you wish to reset the options in the “Wireless Options Configuration” window, click Restore
Default Values.
The system responds by restoring all of the advanced features on this page.

UPnP (Universal Plug and Play)
Microsoft UPnP allows the Gateway to communicate directly with certain Windows operating systems to
trade information about the special needs of certain applications such as messaging programs and
interactive games as well as provide information about other devices on the network, where applicable.
This communication between the operating system and Gateway greatly reduces the amount of manual
configuration required to use new applications and devices.
