Broadcast ESSID Decide if the wireless access point will broadcast
its own ESSID or not. You can hide the ESSID of
your wireless access point (set the option to
‘Disable’), so only people those who know the
ESSID of your wireless access point can get
connected.
CTS Protect Enabling this setting will reduce the chance of
radio signal collisions between 802.11b and
802.11g wireless access points. It’s recommended
to set this option to ‘Auto’ or ‘Always’. However, if
you set to ‘None’, your wireless access point
should be able to work fine, too.
Tx Power You can set the output power of wireless radio.
Unless you’re using this wireless access point in a

2-7 Wireless Security (Data Encryption)
This wireless access point provides many types of wireless security
(wireless data encryption). When you use data encryption, data
transferred by radio signals in the air will become unreadable for those
people who don’t know correct encryption key (encryption password).
There are two ways to set wireless security:
1. Click ‘Security’ on the left of web management interface.
2. Click ‘Set Security’ button when the wireless operating mode you
selected is ‘AP Bridge-Point to Point’, ‘AP Bridge-Point to Multi-Point’,
or ‘AP Bridge-WDS’.
43
There are four types of security level you can select: Disable (no security
- data encryption disabled), WEP, WPA Pre-shared Key, and WPA Radius.
Please refer to the following chapters for detailed instructions.
Please remember it’s very important to set wireless security settings
properly! Without a proper setting, hackers and intruders may gain access
to your local network and do something bad to your computers and
servers, which could cause serious problem.
There are several things you can do to improve wireless security:
1. Always enable data encryption. Only disable it when you want to open
your wireless access point to the public.
2. Never use simple words as encryption password. Use the random
combination of symbols, numbers, and alphabets will greatly improve
security.
3. Use WPA when possible - it's much safer than WEP.
4. Change encryption password when you’ve used it for too long time.
44

enough for home and personal use. But if you need higher level of
security, please consider using WPA encryption (see next chapter).
However, some wireless clients don’t support WPA, but only support
WEP, so WEP is still a good choice for you if you have such kind of
client in your network environment.
When you select ‘WEP’ as encryption type, the following messages will
be displayed:
Here are descriptions of every setup items:
Key Length There are two types of WEP key length: 64-bit and
128-bit. Using ‘128-bit’ is safer than ’64-bit’, but
will reduce some data transfer performance.
Key Format There are two types of key format: ASCII and Hex.
When you select a key format, the number of
characters of key will be displayed. For example, if
you select ’64-bit’ as key length, and ‘Hex’ as key
format, you’ll see the message at the right of ‘Key
46
Format’ is ‘Hex (10 characters), which means the
length of WEP key is 10 characters.
Default Tx Key You can set up to four sets of WEP key, and you
can decide which key is being used by default here.
If you don’t know which one you should use,
select ‘Key 1’.
Encryption Key

4-3 Glossary
Default Gateway (Access point): Every non-access point IP device needs to
configure a default gateway’s IP address. When the device sends out an IP packet, if
the destination is not on the same network, the device has to send the packet to its
default gateway, which will then send it out towards the destination.
DHCP: Dynamic Host Configuration Protocol. This protocol automatically gives
every computer on your home network an IP address.
DNS Server IP Address: DNS stands for Domain Name System, which allows
Internet servers to have a domain name (such as www.Broadbandaccess point.com)
and one or more IP addresses (such as 192.34.45.8). A DNS server keeps a database
of Internet servers and their respective domain names and IP addresses, so that when a
domain name is requested (as in typing "Broadbandaccess point.com" into your
Internet browser), the user is sent to the proper IP address. The DNS server IP address
used by the computers on your home network is the location of the DNS server your
ISP has assigned to you.
DSL Modem: DSL stands for Digital Subscriber Line. A DSL modem uses your
existing phone lines to transmit data at high speeds.
Ethernet: A standard for computer networks. Ethernet networks are connected by
special cables and hubs, and move data around at up to 10/100 million bits per second
(Mbps).
Idle Timeout: Idle Timeout is designed so that after there is no traffic to the Internet
for a pre-configured amount of time, the connection will automatically be
disconnected.
IP Address and Network (Subnet) Mask: IP stands for Internet Protocol. An IP
address consists of a series of four numbers separated by periods, that identifies a
single, unique Internet computer host in an IP network. Example: 192.168.2.1. It
consists of 2 portions: the IP network address, and the host identifier.
The IP address is a 32-bit binary pattern, which can be represented as four cascaded
decimal numbers separated by “.”: aaa.aaa.aaa.aaa, where each “aaa” can be anything
from 000 to 255, or as four cascaded binary numbers separated by “.”:
bbbbbbbb.bbbbbbbb.bbbbbbbb.bbbbbbbb, where each “b” can either be 0 or 1.
A network mask is also a 32-bit binary pattern, and consists of consecutive leading
70
1’s followed by consecutive trailing 0’s, such as
11111111.11111111.11111111.00000000. Therefore sometimes a network mask can
also be described simply as “x” number of leading 1’s.
When both are represented side by side in their binary forms, all bits in the IP address
that correspond to 1’s in the network mask become part of the IP network address, and
the remaining bits correspond to the host ID.
For example, if the IP address for a device is, in its binary form,
11011001.10110000.10010000.00000111, and if its network mask is,
11111111.11111111.11110000.00000000
It means the device’s network address is
11011001.10110000.10010000.00000000, and its host ID is,
00000000.00000000.00000000.00000111. This is a convenient and efficient method
for access points to route IP packets to their destination.
ISP Gateway Address: (see ISP for definition). The ISP Gateway Address is an IP
address for the Internet access point located at the ISP's office.
ISP: Internet Service Provider. An ISP is a business that provides connectivity to the
Internet for individuals and other businesses or organizations.
LAN: Local Area Network. A LAN is a group of computers and devices connected
together in a relatively small area (such as a house or an office). Your home network
is considered a LAN.
MAC Address: MAC stands for Media Access Control. A MAC address is the
hardware address of a device connected to a network. The MAC address is a unique
identifier for a device with an Ethernet interface. It is comprised of two parts: 3 bytes
of data that corresponds to the Manufacturer ID (unique for each manufacturer), plus
3 bytes that are often used as the product’s serial number.
NAT: Network Address Translation. This process allows all of the computers on your
home network to use one IP address. Using the broadband access point’s NAT
capability, you can access the Internet from any computer on your home network
without having to purchase more IP addresses from your ISP.
Port: Network Clients (LAN PC) uses port numbers to distinguish one network
application/protocol over another. Below is a list of common applications and
protocol/port numbers:
71
Application Protocol Port Number
Telnet TCP 23
FTP TCP 21
SMTP TCP 25
POP3 TCP 110
H.323 TCP 1720
SNMP UCP 161
SNMP Trap UDP 162
HTTP TCP 80
PPTP TCP 1723
PC Anywhere TCP 5631
PC Anywhere UDP 5632
PPPoE: Point-to-Point Protocol over Ethernet. Point-to-Point Protocol is a secure
data transmission method originally created for dial-up connections; PPPoE is for
Ethernet connections. PPPoE relies on two widely accepted standards, Ethernet and
the Point-to-Point Protocol. It is a communications protocol for transmitting
information over Ethernet between different manufacturers
Protocol: A protocol is a set of rules for interaction agreed upon between multiple
parties so that when they interface with each other based on such a protocol, the
interpretation of their behavior is well defined and can be made objectively, without
confusion or misunderstanding.
Access point: A access point is an intelligent network device that forwards packets
between different networks based on network layer address information such as IP
addresses.
Subnet Mask: A subnet mask, which may be a part of the TCP/IP information
provided by your ISP, is a set of four numbers (e.g. 255.255.255.0) configured like an
IP address. It is used to create IP address numbers used only within a particular
network (as opposed to valid IP address numbers recognized by the Internet, which
must be assigned by InterNIC).
TCP/IP, UDP: Transmission Control Protocol/Internet Protocol (TCP/IP) and
72
Unreliable Datagram Protocol (UDP). TCP/IP is the standard protocol for data
transmission over the Internet. Both TCP and UDP are transport layer protocol. TCP
performs proper error detection and error recovery, and thus is reliable. UDP on the
other hand is not reliable. They both run on top of the IP (Internet Protocol), a
network layer protocol.
WAN: Wide Area Network. A network that connects computers located in
geographically separate areas (e.g. different buildings, cities, countries). The Internet
is a wide area network.
Web-based management Graphical User Interface (GUI): Many devices support a
graphical user interface that is based on the web browser. This means the user can use
the familiar Netscape or Microsoft Internet Explorer to Control/configure or monitor
the device being managed.
