For security, you can choose not to broadcast your network's SSlD.
Doing so will keep your network name hidden from computers that

Wired Equivalent Privacy [WEP]
WEP is a common protocol that adds security to all Wi-Fi-compliant
Wireless products. WEP was designed to give wireless networks the
equivalent level or privacy prolection as a comparable wrred network
64-3" WEP
64-bit WEP was llrsl Introduced with 64>b|t encryption which Includes
a key length of 40 bits plus 24 additional bits el system—generated data
(64 bits totai). Some hardware manuiacturers reier to 64-bit as 40-bit
encryplion. Shortly after lhe technology was introduced, researchers
lound lhat 64-1)“ encryption was too easy lo decode.
50
Using the Web—Based Advanced User Interface
125-5" WEP
As a result or 64-bit WEP's potential security weaknesses, a more
secure method of iQS-bit encryption was developed. 128- it
encn/ption includes a key length ol1o4 bits plus 24 additional bits ol
system-generated data (128 bits total). Some hardware manuiacturers
referto128-bllas 1U4>Dlt encryption.
Most of the new wireless equipment in the market today suppons
both 54-bit and 128-bit WEP encwption. but you might have oider
equipment that only supports 64-bit WEP Ali Belkin Wireless products
Wili support both 64—bit and 128—bit WEP.
Encryption Keys
Atter selecting either the 64-bit or 128-bit WEP encryption mode. it is
critical that you generate an encryption key. it the encryption key is
not consistent throughout the entire wireless network. your Wireless
networking devices Will be unable to communicate With one another
on your network and you Will not be able to successluliy communicate
Within your network.
You can enter your key by typing in the hex key manually. or you can
type in a passphrase in the “Passphrase” tield and click “Generate“
to create a key. A hex (hexadecimal) key is a combination or numbers
and letters from A4: and oeg. For 64—bit WER you need to enter 10
hex keys For 128-bit WEP, you need to enter 25 hex keys
For Instance
AF DF LB 03 D1. = 64—bit WEP key
C3 03 DF AF OF AB 52 C3 DI. LB C3 D4 E7 =128-bitWEP key
The WEP passphrase is NOT the same as a WEP key. Your Router
uses this passphrase to generate your WEP keys, but dilferent
hardware manufacturers might have diiferent methods on generating
the keys it you have multiple vendors' equipment in your network.
the easiest thing to do is to use the hex WEP key lrom your Router or
access point and enter it manualiy into the hex WEP key table in your
Routers configuration screen.

Wi-Fi Protected Access“ lWPA‘”l
WPA is a new Wi-Fi standard that was designed to improve upon the security
tealures of WEP To use WPA security, the drivers and software 0! your
wireless equipment must be upgraded to suppon WPA These updates Will
be found on the wireless vendor‘s website There are three types of WPA
security. WPA-PSK (no server), WPA (with radius sewer)‘ and WPA2.
WPA-PSK lno server] uses what is known as a pre-shared key as the
network key A network key is basically a password that is between eight
and 63 characters long. it can be a combination of letters, numbers. or
characters Each client uses the same network key to access the network
Typically, this is the mode that Will be used in a home environment.
WPA (with radius server] is a system where a radius server distributes
the network key to the clients automatically This is typically found in a
business environment
WPAz“ requires Advanced Encryption Standard (AES) lor encryption
of data. which otters much greater security than pr. pr uses both
Temporal Key Integrity protocol (TKIP) and (AES) lor encwptlon

Sharing the Same Network Keys
Most Wi-Fi products ship with security turned on So once you have your
network working, you need Io activate WEP or WPA and make sure your
wireless networking devices are sharing the same network key
The Wireless G Desktop Card cannot access the network because it
is using a dinerent network key than the network key that is configured
on the Wireless G Hauler.

A Wireless bridge is a "mode" in which your Wireless Router can directly
connect to a secondary Wireless Access Point. Note that you can only bridge
your Belkln Wireless G Router (model F5D7230-4.
F5D7231-4) to a Belkin Wireless G Range Extender/Access Point (model
F5D7131. F5D7130). We do not support orldging with access points ot other
manutacturers at this time. You can use the brldge mode to extend the range
at your wireless network. or add an extenslon or your network in another
area at your cities or home Without running cables.

Setting Up a Bridge Between your Wireless Router and 3
Secondary Access Point
Bridging your Belkin Router to a secondary Access Point requires that you
access the Router’s Advanced Setup Utility and enter the MAC address
of the Access Point in the appropriate area. There are also a few other
requirements. PLEASE BE SURE TO FOLLOW THE STEPS BELOW, CAREFULLY.
1.
Set your Access Point to the same channel as the Router. By
default, the Router and Access Point channels are set to channel
11 at the factory. If you have never changed the channel, you
don’t need to do anything (for more information on changing
channels, see page 48 of this User Manual).
Find the Access Point’s MAC address on the bottom of the
Access Point. There are two MAC addresses on the bottom label.
You will need the MAC address named “WLAN MAC Address“.
The MAC address starts with 003OBD and is followed by six
other numbers or letters (i.e. 003OBD—XXXXXX). Write the MAC
address below. Go to the next step.
Place your secondary Access Point within range of your Wireless
Router and near the area where you want to extend the range
or add the network segment. Typically, indoor range should be
between 100 and 200 feet.
Connect power to your Access Point. Make sure the Access
Point is on and proceed to the next step.

Configuring the Firewall
Your Router is equipped with a firewall that will protect your network from
a wide array at common hacker attacks including:
0 IP Spoofing
' SYN flood
- Land Attack
- UDF' flooding
- Plng of Death (POD)
- Tear Drop Attack
- Denial 0! Service (Dos)
- ICMF' detect
- IP wlth zero length
- FlIP detect
. Smurt Attack
- Fragment flooding
- TCP Null Scan
The firewall also masks common ports that are lrequently used to attack
networks These ports appear to be “Stealth". meaning that lor all Intents
and purposes. they do not exist to a would-be hacker. You can turn
the 1Irewal|1unction on If needed: however. while disabling the llrewall
protection will not leave your network completely vulnerable to hacker
attacks, It Is recommended that you leave the firewall enabled.

The “Virtual Servers" function will allow you to route external (Internet)
calls for services such as a web server (port an), FTP server (Port 21),
or other applications through your Router to your internal network. _
Since your internal computers are protected by a firewall, computers
outside your network (over the Internet) cannot get to them because
they cannot be "seen" A list oi common applications has been
provided in case you need to configure the “Virtual Server" function
for a specific application You will need to contact the application
vendor to line out which port settings you need.
