so that the above private IP can be used for configuration access. If Internet
access through the WAN port is enabled by the user, port 8080 must be
used for configuration access. In this case, you would enter the following:
http://(WAN Port IP Address):8080 in your web browser.
W eb access through the WAN port (over the Internet) is disabled by default
If your computer’s IP is not on the
same subnet as the SpaceLink Home
Gateway , you will be asked to change
it. The IP address can be any number
from 2 to 254 that is not used by
another device.
Using a proxy server for your
LAN requires that you set an exception for the SpaceLink Home
Gateway or else connection will
fail.

SSID & Channel
The SSID is an identification string of up to 32 ASCII characters that
differentiate one SpaceLink Home Gateway or Access Point from another.
The SSID is also referred to as the “ESSID” or “Extended Service Set ID.”
Y ou can use the default SSID and radio channel unless more than one SpaceLink
Home Gateway or Access Point is deployed in the same area. In that case, you
should use a different SSID and radio channel for each SpaceLink Home
Gateway or Access Point. All the SpaceLink Home Gateways and SpaceLink
802.11b client adapters must have the same SSID to allow a wireless mobile
client to roam between the SpaceLink Home Gateways. By default, the
SSID is set to “default”.
Channel
IEEE 802.11b devices are direct sequence spread spectrum devices that
spread a radio signal over a range of frequencies. The range of frequencies
3. Utilities
used by a direct sequence device is called a Channel.
Chapter 3 - Home Gateway Utilities
The IEEE 802.11b specification supports up to 14 overlapping Channels
for radio communication. But only 11 Channels are supported in the United
States and therefore on the SpaceLink Home Gateway. To minimize
interference, configure each the SpaceLink Home Gateway to use Nonoverlapping channels. Non-overlapping channels have 25Mhz separation
beginning at the first allowed channel for the country (for the US and most
of Europe, channels 1, 6 & 11 are used).
Make sure that the SpaceLink Home Gateways sharing the same Channel
(or Channels close in number) are as far away from each other as possible,
based on the results of your site survey of the facility . You can find the site
survey utility in the SpaceLink PC card or CF card setup CD.
Basic Data Rate
Select “1, 2, 5.5 & 11Mbps” to maximize performance. Use “1 & 2 Mbps”
only when backward compatibility is needed for some older wireless LAN
cards with a maximum bit rate of 2Mbps.
The IEEE 802.11b specification supports four data rates: 11 Mbps, 5.5 Mbps,
2 Mbps, and 1 Mbps. As a wireless mobile client travels further and further
away from the SpaceLink Home Gateway , the data rate automatically decreases
in order to maintain a usable radio connection. Therefore, a client that is close
to an the SpaceLink Home Gateway may operate at 11 Mbps, but a client that
is far away from the SpaceLink Home Gateway may operate at 2 Mbps.
34 SpaceLink Home Gateway
Chapter 3 - Home Gateway Utilities
Supported Clients
802.11b products can operate at 11 Mbps, 5.5 Mbps, 2 Mbps or 1 Mbps. This
allows 802.11b devices to communicate with any existing 802.1 1 direct sequence
devices that operate only at 1 or 2 Mbps. By default, the SpaceLink Home Gateway
will support both 802.11b and 2 Mbps 802.1 1 direct sequence clients.
WEP
The IEEE 802.11b standard specifies an optional encryption feature, known
as Wired Equivalent Privacy or WEP, that is designed to provide a wireless
LAN with a security level equal to what is found on a wired Ethernet network.
WEP encrypts the data portion of each packet exchanged on the 802.11b
network using either a 64-bit or 128-bit encryption algorithm. In addition,
WEP is also used in conjunction with the optional Shared Key
Authentication algorithm to prevent unauthorized devices from associating
with an 802.11b network.
Enabling WEP can protect your data from eavesdroppers. If you do not
need this feature, select “no” to skip the following setting. The SpaceLink
Home Gateway supports both 64-bit and 128-bit encryption using the W ired
Equivalent Privacy (WEP) algorithm. Select the type of encryption you
want to use (64 or 128 bit) and configure one to four WEP Keys. The “128bit” method is more secure than the “64-bit”.
64/128bits versus 40/104bits
You may be confused about configuring WEP encryption, especially when
using multiple wireless LAN products from different vendors. There are
two levels of WEP Encryption: 64 bits and 128 bits.
Firstly, 64 bit WEP and 40 bit WEP are the same encryption method and
can interoperate in the wireless network. This lower level of WEP encryption
uses a 40 bit (10 Hex character) as a “secret key” (set by user), and a 24 bit
“Initialization Vector” (not under user control). This together makes 64
bits (40 + 24). Some vendors refer to this level of WEP as 40 bits and
others refer to this as 64 bits. ASUS SpaceLink products use the term 64
bits when referring to this lower level of encryption.
3. Utilities
Secondly, 104 bit WEP and 128 bit WEP are the same encryption method
and can interoperate in the wireless network. This higher level of WEP
encryption uses a 104 bit (26 Hex character) as a “secret key” (set by user),
and a 24 bit “Initialization Vector” (not under user control). This together
SpaceLink Home Gateway 35
makes 128 bits (104 + 24). Some vendors refer to this level of WEP as 104
bits and others refer to this as 128 bits. ASUS SpaceLink products use the
term 128 bits when referring to this higher level of encryption.
Magic Word & Generate
Automatically generate four WEP keys. A WEP key is either 10 or 26
hexadecimal digits (0~9, a~f, and A~F) based on whether you select 64 bit
or 128 bit in the WEP pull-down menu. Type a combination of up to 64
letters, numbers, or symbols in the Magic W ord column, then the SpaceLink
Home Gateway Manager uses an algorithm to generate four WEP keys for
encryption. If you want to type in the keys manually , leave this field blank.
The SpaceLink family of products all use the same algorithm to generate
the keys so that they can all use the same WEP key.
Note: This function eases users from having to remember their
3. Utilities
passwords and is compatible to ASUS SpaceLink family of products. But this is not as secure as manual assignment.
Chapter 3 - Home Gateway Utilities
WEP Key
At most four keys can be set. A WEP key is either 10 or 26 hexadecimal
digits (0~9, a~f, and A~F) based on whether you select 64 bit or 128 bit in
the WEP pull-down menu. The home gateway and ALL of its wireless clients
MUST have at least the same default key.
Default Key
The Default Key field lets you specify which of the four encryption keys
you use to transmit data on your wireless LAN. As long as the SpaceLink
Home Gateway or wireless mobile client with which you are communicating
has the same key in the same position, you can use any of the keys as the
default key. If the home gateway and ALL of its wireless clients use the
same four WEP keys, select “key rotation” to maximize security . Otherwise,
choose one key in common as the default key.
Authentication Method
It is suggested to select “Shared Key Only”. If “Open System Only” or
“Shared Key and Open System” is used, the home gateway may accept
connection requests from unauthorized wireless clients.
