Wireless – Security
The next screen is the Wireless – Security screen which allows you to select the
network authentication method and to enable or disable WEP encryption. Note
that depending on the network authentication that is selected, the screen will
change accordingly so additional fields can be configured for the specific
authentication method.
Network authentication methods include the following—
• Open—anyone can access the network. The default is a disabled WEP
encryption setting.
• Shared—WEP encryption is enabled and encryption key strength of 64-bit or
128-bit needs to be selected. Click on Set Encryption Keys to manually set
the network encryption keys. Up to 4 different keys can be set and you can
come back to select which one to use at anytime.
• 802.1X—requires mutual authentication between a client station and the
router by including a RADIUS-based authentication server. Information
about the RADIUS server such as its IP address, port and key must be
entered. WEP encryption is also enabled and the encryption strength must
also be selected.
• WPA—(Wi-Fi Protected Access)— usually used for the larger Enterprise
environment, it uses a RADIUS server and TKIP (Temporal Key Integrity
Protocol) encryption (instead of WEP encryption which is disabled). TKIP
uses128-bit dynamic session keys (per user, per session, and per packet
keys).
• WPA-PSK (Wi-Fi Protected Access – Pre-Shared Key)—WPA for home and
SOHO environments also using the same strong TKIP encryption, per-packet
key construction, and key management that WPA provides in the enterprise
environment. The main difference is that the password is entered manually.
A group re-key interval time is also required.
• WPA2 (Wi-Fi Protected Access 2)—second generation of WPA which uses
AES (Advanced Encryption Standard) instead of TKIP as its encryption
method. Network re-auth interval is the time in which another key needs
to be dynamically issued.
• WPA2-PSK (Wi-Fi Protected Access 2 – Pre-Shared Key)—suitable for home
and SOHO environments, it also uses AES encryption and requires you to
enter a password and an re-key interval time.
• Mixed WPA2 / WPA—during transitional times for upgrades in the
enterprise environment, this mixed authentication method allows
“upgraded” and users not yet “upgraded” to access the network via the
router. RADIUS server information must be entered for WPA and a as well
as a group re-key interval time. Both TKIP and AES are used.
• Mixed WPA2 / WPA-PSK—useful during transitional times for upgrades in
the home or SOHO environment, a pre-shared key must be entered along
with the group re-key interval time. Both TKIP and AES are also used.

Find out the following values from your ISP before you change them.
• VPI: Virtual Path Identifier. The valid range is 0 to 255.
• VCI: Virtual Channel Identifier. The valid range is 32 to 65535.
• Service Category: Five classes of traffic are listed—
o UBR Without PCR (Unspecified Bit Rate without Peak Cell Rate)—
UBR service is suitable for applications that can tolerate variable
delays and some cell losses. Applications suitable for UBR service
include text/data/image transfer, messaging, distribution, and
retrieval and also for remote terminal applications such as
telecommuting.
o UBR With PCR (Unspecified Bit Rate with Peak Cell Rate)--
o CBR (Constant Bit Rate)—used by applications that require a fixed
data rate that is continuously available during the connection time.
It is commonly used for uncompressed audio and video information
such as videoconferencing, interactive audio (telephony), audio /
video distribution (e.g. television, distance learning, and pay-per-
view), and audio / video retrieval (e.g. video-on-demand and audio
library).
o Non Realtime VBR (Non-Real-time Variable Bit Rate)—can be used
for data transfers that have critical response-time requirements
such as airline reservations, banking transactions, and process
monitoring.
o Realtime VBR (Real-time Variable Bit Rate)—used by time-sensitive
applications such as real-time video. Rt-VBR service allows the
network more flexibility than CBR.
• Quality of Service: Can be enabled only for UBR without PCR, UBR with
PCR, and Non Realtime VPR.

Advanced features of the wireless LAN interface can be configured in this section.
Settings can be configured for the following—
• AP Isolation—if you select enable, then each of your wireless clients will
not be able to communicate with each other.
• Band—a default setting at 2.4GHz – 802.11g
• Channel—802.11b and 802.11g use channels to limit interference from
other devices. If you are experiencing interference with another 2.4Ghz
device such as a baby monitor, security alarm, or cordless phone, then
change the channel on your router.

• 54gTM Rate—the wireless link rate at which information will be received and
transmitted on your wireless network.
• Multicast Rate—the rate at which a message is sent to a specified group of
recipients.
• Basic Rate—the set of data transfer rates that all the stations will be
capable of using to receive frames from a wireless medium.
• Fragmentation Threshold—used to fragment packets which help improve
performance in the presence of radio frequency (RF) interference.
• RTS Threshold (Request to Send Threshold)—determines the packet size
of a transmission through the use of the router to help control traffic flow.
• DTIM Interval—sets the Wake-up interval for clients in power-saving mode.
• Beacon Interval—a packet of information that is sent from a connected
device to all other devices where it announces its availability and readiness.
A beacon interval is a period of time (sent with the beacon) before sending
the beacon again. The beacon interval may be adjusted in milliseconds (ms).
• Xpress Technology—a technology that utilizes standards based on
framebursting to achieve higher throughput. With Xpress Technology
enabled, aggregate throughput (the sum of the individual throughput
speeds of each client on the network) can improve by up to 25% in 802.11g
only networks and up to 75% in mixed networks comprised of 802.11g and
802.11b device.
• 54g Mode— 54g is a Broadcom Wi-Fi technology.
• 54g Protection—the 802.11g standards provide a protection method so
802.11g and 802.11b devices can co-exist in the same network without
“speaking” at the same time. Do not disable 54g Protection if there is a
possibility that a 802.11b device may need to use your wireless network. In
Auto Mode, the wireless device will use RTS/CTS (Request to Send / Clear
to Send) to improve 802.11g performance in mixed 802.11g/802.11b
networks. Turn protection off to maximize 802.11g throughput under most
conditions.
• Preamble Type— this is the length of the CRC (Cyclic Redundancy Check)
block for communication between the router and wireless clients. High
network traffic areas should select Short preamble type.
• Transmit Power— this is the percentage of power that should be
transmitted from your wireless router. Select from 20%, 40%, 60%, 80%, and
100%.
