Chapter 1 Introduction
Overview of the AIR-104/204
The AIR-104 and the AIR-204 are small desktop
devices that mediate between your local area network
(LAN) and the Internet. Each AIR-104/204 provides dual
modem connections to access the Internet (the AIR-104
has two external modem ports, while the AIR-204 has
one built-in modem and one external modem port). Your
LAN connects to the AIR-104/204 via a four-port dualspeed Fast Ethernet repeater hub. The AIR-104/204
also features an auxiliary port for a directly connected management console. Data comes in to the
AIR-104/204 from your local network and then is “directed” to the Internet, and vice versa. The AIR104/204 dual-modem design allows connections to either one or two Internet accounts to be
opened and managed automatically.
Figure 1-1
Internet Access with the AIR-104/204
Accessing the Internet
The AIR-104/204 provides shared Internet access, so that everyone on your LAN can surf the web
and send/receive e-mail or files.
The AIR-104/204 utilizes single IP address technology that greatly simplifies the configuration process: the AIR-104/204 automatically acquires the necessary IP addresses when the connection to
the Internet is established, and distributes access to your entire network. You don’t need to apply for
and assign an IP address to each PC or workstation on your network.
The AIR-104/204 features “bandwidth on demand”. Any user’s initial access of an Internet resource
will cause a connection to the Internet to be set up automatically. As the traffic builds up (e.g., more
users try to access the Internet, or the same user generates a lot of traffic), the AIR-104/204 will
automatically establish a second connection through a second Internet account, if one has been
configured. As traffic decreases, one Internet connection will be taken down, until finally, after a configurable period of inactivity, the remaining Internet connection will also be disconnected.
User Guide for AIR-104/AIR-204 1-1
Chapter 1 Introduction
Security overview
More and more people are concerned about security of their data in this Internet era.
The AIR-104/204 provides many ways to help make your network and data secure:
• The AIR-104/204 uses a private IP addressing scheme that protects devices on your LAN from
access by users from the Internet outside.
• All access to the AIR-104/204 (Console, Talent and the browser-based Internet Configuration
Console) is protected by password verification.
• Internet access can be configured to occur only at certain times of the day and on certain days
of the week.

of operation for LAN port 1 is located along the right edge of the router case (see Figure
2-2). Locate the switch and set it to NORMAL mode. Then use an RJ-45 to RJ-45 cable
(not supplied) to connect LAN port 1 to your PC’s Ethernet interface.
Connecting PC’s to the router via a hub or switch
If your network contains more than four PC’s, you will need first to connect the majority of
your PC’s to each other with an external hub or switch, and then connect that hub or
switch to LAN port 1 on the AIR-104/204 (see Figure 2-1). In this configuration, LAN
ports 2,3, and 4 on the AIR-104/204 can still directly connect to PC’s as described
above.
Step 1 Connect your PC’s to the external hub or switch. Consult the manufacturer’s
instructions for direction.
Step 2 Connect a node port (one that would normally be used to connect a PC
directly) on the external hub or switch to LAN port 1 on the AIR-104/204,
using an RJ-45 to RJ-45 cable (not supplied). Locate the switch that controls
the mode of operation for LAN port 1 on the AIR-104/204, and set it to
UPLINK (this switch is located along the right edge of the router case). See
Figure 2-2. If you are using a special uplink port on the external hub or switch
to connect to LAN port 1 on the AIR-104/204 , then set the mode of
operation for LAN port 1 on the AIR-104/204 to
NORMAL.

Chapter 3 Configuring PC's in the Network
Why do I need to configure PC's?
Any PC that is connected to the network (either plugged directly into the AIR-104/204 or
uplinked from an external hub/switch) requires configuration before it can communicate
with the AIR-104/204.
Each PC must have TCP/IP installed. Additionally, each PC must either be configured to
obtain an IP address through a DHCP server, or must have its IP address set manually.
Only PC’s configured in this manner can share Internet access by means of the AIR-104/
204 .
Note: Any TCP/IP capable workstation can be used to communicate with or through
the AIR-104/204. Other types of workstations may or may not be compatible; please
consult the manufacturer’s documentation.
Note: It is strongly recommended that you configure each network PC to obtain its IP
address automatically from a DHCP server. Only this configuration procedure is escribed
below. If you wish to set network IP addresses manually, please consult more detailed
TCP/IP documentation.
When do I need to configure PC's?
When you first install the AIR-104/204 in your network, you will need to configure a PC so
that you can use it, in turn, to configure the AIR-104/204.
After the AIR-104/204 is properly configured, you will need to configure each PC that is
connected to the network.
What do I need to configure PC's?
For configuration, a PC must have a properly-installed Ethernet or Fast Ethernet network
interface, and that network interface must be connected properly to the network (either
connected directly to a LAN port of the AIR-104/204, or uplinked via a properlyconnected external hub or switch).
There are no operating system requirements for PC’s to be configured. However,
Windows 95 and Windows 98 are the most popular operating systems currently in use;
the procedure described below applies for Windows 95/98. To configure PC’s or
terminals running other operating systems, consult the relevant user manual for
information about installing TCP/IP.

Before the AIR-104/204 can establish a connection with your Internet Service Provider
(ISP), you may need to input some information about the modem(s) you have connected
to it, so that the AIR-104/204 can communicate properly with the modem(s).
Additionally, you may configure the AIR-104/204 to enable or disable either of the
modem ports. You should disable those modem ports (external or internal) that are not
connected to live phone lines, so that the AIR-104/204 will not keep attempting to set up
Internet connections with them, thereby causing delays for the users on your LAN as the
AIR-104/204 continually attempts to make a call that can never go through. Disabling a
modem causes the AIR-104/204 to ignore it, and instead try the call only on the
remaining good line.
The simplest procedure for configuring the AIR-104/204 utilizes the Internet
Configuration Console (ICC), which is fully described above in the section entitled

How to configure your Internet connection
After you have configured the modem connection(s) of your AIR-104/204 , the last step
required for Internet access is configure your Internet connection.
Unlike more complicated routers, the AIR-104/204 is specifically optimized for userfriendly Internet access. You may safely ignore the whole system of applying for and
assigning IP addresses - the AIR-104/204 handles all these processes for you
automatically.
To allow the AIR-104/204 to communicate with your Internet Service Provider (ISP) for
Internet access, you just need to input your ISP’s contact telephone number, your ISP
account name, and your ISP account password. The AIR-104/204 will take care of
everything else, and you can begin accessing the Internet right away.
The simplest procedure for configuring the AIR-104/204 utilizes the Internet
Configuration Console (ICC), which is fully described above in the section entitled

Viewing the Connection Log
To enhance network monitoring and cost control, the AIR-104/204 keeps a running
record of its Internet access activity (the Connection Log). The Connection Log records
the date and time of occurence for two different categories of events: trigger events and
connect /disconnect events.
A trigger event is recorded every time that a network device’s request to access the
Internet causes the AIR-104/204 to attempt to open a new connection to your ISP.
Reviewing trigger events allows you to identify which workstation (and, more specifically,
which application) creates the demand for Internet access.
A connect /disconnect event is recorded every time that a connection between the AIR-
104/204 and your ISP is established or taken down, respectively. Reviewing connect
and disconnect events allows you to determine your telephone charges and Internet
service charges.
The Connection Log is large enough to record up to 128 separate events. If the
Connection Log fills up, the oldest entries are overwritten first, in favor of new entries.

Setting the time
The AIR-104/204 maintains a real-time clock, which is used to provide timestamps for
entries in the Connection Log and the System Log. The AIR-104/204’s internal clock
also controls Internet access time restrictions. For more information about the
Connection Log and Internet access time restrictions, see the relevant sections in this
chapter; for more information about messages that may appear in the System Log, see
Appendix A
The AIR-104/204 does not contain a battery to back up its internal clock, so the time will
not be maintained across a system reset or power-down. Therefore, in order to utilize
properly any feature that requires the clock to be accurate, you will need to reset the AIR104/204’s clock to the correct date and time after a system reset or power-down.
However, please note that when you set your local time zone and current Daylight

For your convenience, and to ensure consistency, the AIR-104/204 is designed to
automatically capture the date and time kept by your management PC whenever it logs
onto the ICC. If you wish to reset the AIR-104/204’s clock, you should first ensure that
your management PC is set to the correct date and time, and then apply your
management PC’s time to the router. The procedure is outlined below. The same
procedure allows you to modify your local time zone, as well as your current Daylight

Setting Internet access time restrictions
To enhance security, efficiency, and cost control, you can configure the AIR-104/204 to
disallow Internet access except on certain days, at certain times.
In order for this feature to be effective, the AIR-104/204’s internal clock must already
have been set to the correct date and time. See
When the AIR-104/204 has undergone a system reset or a power-down, at first the date
and time will be unset. If you have configured the AIR-104/204 to restrict Internet
access to certain days and times, it will not be able to comply with these restrictions until
you set the correct date and time. Therefore, the AIR-104/204 can be configured to
respond to this circumstance either by freely allowing Internet access, or by disallowing
all Internet access until the clock is set. Once you have set the correct date and time
from a management PC, the AIR-104/204 will once again begin complying with the
underlying Internet access time restrictions stored in memory.

What is "management"?
The management functions of the AIR-104/204 provide you with convenient tools
necessary to update the AIR-104/204 over the long term. This chapter covers the
following common tasks:
• How to save or clear configuration changes
• How to restart the AIR-104/204
• How to change my ICC password
• What if I forget the ICC password?
• How to upgrade the AIR-104/204’s software
How to save or clear configuration changes
While fine-tuning your Internet access, you may need to make temporary adjustments to
the AIR-104/204; therefore, the configurations you enter will NOT be saved to flash

What if I forget the ICC password?
For your security, a password is REQUIRED to log onto the AIR-104/204. If you forget
the ICC password, the only way to recover is to clear the entire configuration manually
and return the unit to its original state as shipped from the factory. Unfortunately, this will
also result in the loss of your entire configuration database; all settings will need to be reentered. To clear the configuration manually and restore the password to the default,

How to upgrade the AIR-104/204 software
Periodically, you may need to upgrade the AIR-104/204’s firmware (firmware is the
software that controls the AIR-104/204’s operations). Normally, this is done when you
discover a problem that is resolved in a newer version of the firmware, or when Acer
produces an updated version of the firmware which includes new features that you need.
Otherwise, if you are happy with your current situation, you may not want to upgrade
even if a new version is available. Please check the Acer Netxus website for information
about the latest firmware upgrades (the software can be downloaded directly from the
website):
www.acernetxus.com.tw
The upgrade procedure follows:
Step 1 Using a web browser, connect to the Internet and acess the Acer Netxus
website at:
www.acernetxus.com.tw
Following the directions on the website, download the desired version of the
software and install it in your local PC environment.

What is the Command Line Interface?
Although the AIR-104/204 is most conveniently configured and managed via the Internet
Configuration Console (described in
router using the Command Line Interface (CLI). In fact, certain feature of the AIR-104/
204 are ONLY accessible by means of the CLI. The CLI is a text-based user interface,
unlike the graphic interface of the ICC, and it MUST be used to control the AIR-104/204
from a directly-connected console PC.
Using the Command Line Interface
There are two ways to access the AIR-104/204’s CLI:
• Telnet

to one of your own choosing. At all times, the password for the CLI is identical to the
password for the ICC; if you change one, then you will also change the other at the same
time. Please note that the password is case-sensitive. As you type in the password,
your keystrokes will be echoed as asterisks (*). When you hit the Carriage Return, the
password you have entered will be tested against the current password. If the password
string is validated, the command prompt will be displayed:
Command>
The user may now begin to issue commands. Most of the commands are single-line
commands, and no commands are context-sensitive: each command is independent of
other commands before or after it.
While entering commands with the CLI, please make a note of the following general
guidelines:
• At any time, the user may type a “ ?” (preceded by a space) to request for help
concerning what the user can enter next. If the CLI is expecting a keyword when the
user types “?”, then all valid keywords will be displayed for selection, and the
unfinished command will be re-displayed withe cursor at the end for the user to finish
the input.
• Instead of entering a full keyword, the user may simply enter the first part of the
keyword and then hit
keyword, unless the characters entered thus far do not uniquely identify a keyword,
in which case nothing will happen. If the user is unsure how to complete the
keyword, she may simply type as many characters as she knows, followed by a “?”;
the system will then display all valid keywords which match the partial input.
• At any time, the user can type control-p (^p, by pressing both the Ctrl key and the
^p key at the same time) to repeat the previous command, or control-n to return to

• Profile Name means an Internet profile, not the LAN port.
• xxx/yyy means xxx, or yyy;
• num means any integer number (such as 19200, 9600, ...);
• MacAddr, or nn-nn-nn-nn-nn-nn means any MAC address in hexadecimal format,
where each nn can be 00, 01, ... 09, 0A, 0B, 0C, 0D, 0E, 0F, 10, 11,… FF;
• ipAddr, netMask, or xxx.xxx.xxx.xxx means any ip address or network mask, where
xxx is a decimal integer between 0 and 255

Chapter 7 Command Line Interface
Command List
DHCP Commands
The Dynamic Host Control Protocol (DHCP) is a client/server protocol1 that defines an
efficient and convenient means of dynamically assigning IP addresses and other
networking parameters for a period of time upon request. In an AIR-104/204
environment, this means either the dynamic assignment of private IP addresses to PCs
co-residing on the LAN segment with the AIR-104/204, or a static assignment of these
addresses according to the station identification (the MAC address) of the requesting
client.
Since the SOHO Router is configured with a private IPaddress for its LAN connection,
the DHCP server is automatically enabled. (The DHCP function is disabled if the router
discovers another DHCP server at initialization time, or if the user has explicitly disabled
this function.) DHCP clients residing in LAN-resident machines, such as those running
Windows 95/98, may then request a lease on an IP address from a DHCP server. As the
term implies, the assignment of the address is temporary. The default lease period in a
AIR-104/204 DHCP server is ten hours. The DHCP client is responsible for the renewal of
the lease.
Both static and dynamic DHCP assignments are supported. The range of IP addresses
in the dynamic pool from which the server selects an address to satisfy a request is fixed
and extends from 192.168.168.1 to 192.168.168.229, with the highest available address
being assigned first. Statically assigned addresses must be within this range as well
to 20 static DHCP assignments may be configured and saved.

configured with the set ip private… command (or its HTTP equivalent). The term of the
lease is 10 hours. The factory default is enabled.

1.The Internet Engineering Task Force (IETF) defines DHCP in RFC-2131 and RFC-
2132.
2. In certain cases, statically assigned addresses may be above this address. Some
AIR-104/204 models may not require this entire range and therefore, static DHCP
assignments from this range may be used.

The IP network corresponding to the set ip private command becomes the private

this network are no longer accessible from public devices on the Internet side. All devices
within this private network are represented by one single IP address: the IP address
received from an Internet Service Provider at connect time. Note that 192.168.168.230 is
the default private address used for the AIR-104/204, and the private network address is
192.168.168.0, and therefore all private devices should have IP addresses within the
range of 192.168.168.1 to 192.168.168.254. Private IP addresses may be any Class C
address with the range 192.168.xxx.0, where xxx is between 0 and 255.

System Commands
change password
Description
the Command Line Interface or the Internet Configuration Console utility. A password is a
character string that starts with a letter and contains at least 6 and up to a total of 15
alphanumeric characters. The password is case sensitive. The default factory setting is
“password”.
If you forget the Internet Configuration Console password, the only way to recover is clear
the entire configuration and return the unit to its original state as shipped from the factory.
Unfortunately, this means that you have to re-enter all of your configuration data.
To clear the configuration and restore the password to the default, follow these steps:
Connect a console to the AIR-104/204 Aux/Console port. Turn off the AIR-104/204, then
turn it on again. In the console window, youll see the message Loading firmware...
When you see the message "Ready",
The AIR-104/204 will now reset. When this is complete, the AIR-104/204 will return all
settings to the factory default. The password will once again be “password”.

Description
system from a directly attached PC running the terminal emulation software (one with zmodem file download capability). Note that this command cannot be used from a telnet
session. This is an alternative to downloading the software using the Internet
Configuration Console browser utility.
Since the router will reset after this operation is complete, the system will first prompt for
the confirmation. The system will ask the user to select the download speed. The user
may then change the terminal baud rate for a faster download and press enter to
continue (some terminal emulators require a disconnect followed by a connect in order
for the changed parameters to take effect). Select the Z-modem protocol for use in
downloading the firmware. The user then selects (opens) the firmware file for actual
downloading.
Upon completion of the download, the router will reset and is therefore intrusive to any
active Internet session.

down (log level 2), … as well as certain protocol progress messages for debugging
purposes.
This command shows the next 22 entries of the system log. For example, if there are 60
entries in the log, the first show system log command will show log entries 1 through 23,
the next command will show entries 24 through 46, and the next command will show
entries 47 through 60, followed by 1 through 9. When the system powers up, the log is
re-initialized and contains no entries. As time passes, when the 128-entry log table
becomes full, new entries will simply replace the oldest entries, thus a first-in, first-out

Short for Internet Service Provider, a company that provides access to the Internet. For a
monthly fee, the service provider gives you a software package, username, password
and access phone number. Equipped with a modem, you can then log on to the Internet
and browse the World Wide Web and USENET, for example, and send and receive email worldwide.

Appendix B Glossary
local area network (LAN)
A computer network that spans a relatively small area. Most LANs are confined to a
single building or group of buildings. However, one LAN can be connected to other LANs
over any distance via telephone lines and radio waves. A system of LANs connected in
this way is called a wide-area network (WAN)
MAC address
Short for Media Access Control address, a hardware address that uniquely identifies
each node of a network. In IEEE 802 networks, the Data Link Control (DLC) layer of the
OSI Reference Model is divided into two sublayers: the Logical Link Control (LLC) layer
and the Media Access Control (MAC) layer. The MAC layer interfaces directly with the
network media. Consequently, each different type of network media requires a different
MAC layer.
ping
A utility that can be used to send a packet to a remote device (expecting the same
packet to be echoed back if the destination is functioning properly). This is often used to
check if a remote device is reachable or not, and what the round trip delay is. Some
variation of the utility also provide detailed routing information such as which intermediate
routers the packet goes through, so that if the echo packet does not come back, the
break in the path can easily be identified.
PPP
PPP (Point-to-Point protocol) is a communications protocol for transmitting information
over standard telephone lines. A PPP account is a dial-up account used to connect to
the Internet. It is a dial-up account that actually communicates with another computer to
gain Internet access.
router
An intelligent, multi-network interface device that will forward a packet received from one
interface to another. When a packet is received, its destination network address is
checked against the routing table. Then the router determines where to forward the
packet. This next destination should, in theory, be one hop closer to the final destination.
TCP/IP
Acronym for Transmission Control Protocol/Internet Protocol, the suite of
communications protocols used to connect computers on the Internet. TCP/IP uses
several protocols, the two main ones being TCP and IP.
Telnet
A terminal emulation program for TCP/IP networks such as the Internet. A Telnet client
program runs on your computer and connects your PC to a Telnet server elsewhere in
the network. You can then enter commands through the Telnet program and they will be
executed as if you were entering them directly on the server console. This enables you to
control the server and communicate with other servers on the network. To start a Telnet
session, you must log in to a server by entering a valid username and password.
