Getting started
You can build a Wireless LAN environment that connects up to 49 computers (a maximum 16 is recommended) by connecting the Wireless
LAN Access Point PCWA-A100 (called the Access Point below) a computer in which the Wireless LAN PC Card PCWA-C100 is inserted.
While enabling the sharing of files between all computers connected over the same Wireless LAN, it is also possible for multiple of computers
within the same LAN system to connect to the Internet, if the Access Point is connected to a telephone line, an ISDN router, cable modem or to
an xDSL modem. Furthermore, you can build a Wireless LAN environment between computers that are installed with the Wireless LAN PC Card
without having to use the Access Point. (This is called peer-to-peer connection.)

I cannot connect for a short period of tim e afte r click ing on the To Dis conne ct button.
The Access Point w ill not receive connection commands for approximately one minute after manually disconnecting it. Please w ait for one minute. This is
also true for other clients that are connected to the Access Point.
The re is no com m unication w ith the Acce s s Point w he n changing from the LAN m ode to the Phone m ode .
With the LAN mode, the Access Point is the DHCP client w ith regard to the ISDN Router. After disconnecting from the ISDN Router (DHCP server),
computers installed w ith the Wireless LAN PC Card try to read the IP address again w hen the IP address lease time has ended. This is because the ISDN
Router (DHCP server) cannot be found and it falls into a state in w hich it cannot acquire the IP address.
Either reset using the Custom Access Point Setup Utility or return the Access Point to the ex-factory status using the Reset mode. Then, use the Access
Point Setup Utility to make the settings for the customer's Access Point. You can also use the Softw are Reset mode to set the IP address to an
appropriate setting.

First, connect the ISDN Router and the PCWA-A100 Access Point, then connect the pow er supply.
I cannot com m unicate w ith the Acce s s Point afte r changing to the LAN m ode .
Possibly, acquisition of the IP address failed.
When you set to the LAN mode, the Access Point acts as a bridge betw een the Ethernet and Wireless sides. With this mode, the Access Point stops the
functions of the DHCP server. In other w ords, each client tries to get the IP address from the DHCP server (normally the ISDN Router) other than the
Access Point.
Therefore, if there is nothing connected to the Access Point's 10BASE-T connector (Ethernet connector), and w hen connected to a LAN that does not
have an operational DHCP server, the Wireless client computer w ill not be able to obtain the IP address from the DHCP server.
First, connect the Access Point's 10BASE-T connector to a netw ork on w hich the DHCP server is operating, then connect to the pow er supply.
Confirm that the Access Point has completely started, then perform either of the follow ing to re-acquire the client's IP address.

The Acce s s Point is conne cte d to the te le phone line and the pow e r is on. What's the proble m ?
The Access Point can no longer communicate w ith the Wireless LAN PC card installed in the computer.
In the LAN mode, the Access Point becomes a client to the existing DHCP server, such as an ISDN router. Likew ise, the Wireless LAN PC card installed
in the computer becomes a client of the existing DHCP server.
Page 32
After disconnecting from the ISDN router, the Access Point and Wireless LAN PC card attempt to acquire new IP addresses w hen their lease on existing

addresses expires. How ever, they are unable to acquire IP addresses because the DHCP server is not found, so communication is not possible.
When this occurs, temporarily reestablish communication by temporarily assigning an IP address to the Access Point, using the same netw ork segment
as for PCs on the netw ork. Communication can then be reestablished by changing settings. Click here for details.
Another w ay to reestablish communication is to use one of the Access Point's tw o reset modes to forcibly change the Access Point setting.
Us e the re s e t m ode to re s tore the Acce s s Point to the factory de fault s e ttings :
After placing the Access Point in the reset mode, restore it to the factory default settings by using the Access Point Firmw are Utility. See the Access
Point Firmw are Upgrade Utility Help for the procedure.

Cable Modem mode
I cannot connect to the Inte rne t w ith m y cable m ode m .
Depending on the details of the agreement w ith your contracted cable operator, there are cases in w hich only one client can be connected to one cable
modem. In this case, your cable modem remembers the MAC address of the PC netw ork card that you have connected until now . It rejects requests for
connections to the Internet from anything other than that MAC address.
How to handle
Turn off the pow er to the cable modem that you use and w ait for a few seconds. Doing so w ill cause it to delete from the cable modem the MAC
address that it has stored.
Also, depending on the cable television company w ith w hich you have an agreement, the MAC address may be registered. If this is the case, you may
need to request a change of the MAC address to your cable provider.
Either refer to the cable modem operations manual or contact your cable television company for details.

General connections with the Access Point
Sudde nly, I can't conne ct w ith the Acce s s Point.
The follow ing causes can be considered.



Access Point failure or the pow er is unplugged.
Confirm w hether or not the pow er supply is connected.



Access Point is not connected to the netw ork.
If the Access Point is in ISDN mode, communications cannot be established betw een the Access Point and the Wireless client if the Access Point
is not connected to the ISDN Router or to the LAN.
Check if it is. Also, confirm if the ISDN Router DCHP server function and DCHP server on the LAN are operating normally.
It is explained in detail here, if you have any questions.



The Access Point settings w ere changed.
If multiple clients are connected to the Access Point, one of them may have changed their Access Point settings.
First, you must search for the client w hose Access Point settings w ere changed and ask w hat changes w ere made.

If the Encryption Key w as changed, it is necessary for you to change the Access Point registration using the Wireless Palette.

If the connection mode w as changed, it is possible that communications w ith the Access Point cannot be established because the IP address
could not be acquired.

If this is the case, determine one person to be the netw ork administrator for the Access Point and change the Access Point Setup Utility passw ord to
its ex-factory setting, then change the settings so that no one other than that netw ork administrator can change the settings. When the netw ork
administrator is changing the settings, it is necessary to determine the rules such as notifying other members in advance. Refer here, for details
regarding the passw ord for the netw ork administrator.
Sw itching the Acce s s Point fails m any tim e s



Sym ptom 1
Three Access Points are being used. When you sw itch to a different Access Point:
1.

The address is acquired by DHCP.

The IP address of the Access Point is displayed in the Wireless Palette Advanced information.

In this case, communications cannot be established regardless of the states described above. Also, there is no response even to ping to the Access
Point. What causes can be considered?
HANDLING
First, confirm the follow ing items.
3.

After sw itching, the Access Point is either in Phone mode or Cable Modem mode.

The setting is the same as a private IP address (such as 10.0.1.1).

In this case, communications cannot be established because the IP address of the ARP table on the PC side and old information remains in the table
for the MAC address. In other w ords, the MAC address that remains in the PC is the MAC address of the Access Point from before the sw itch so
normal communications cannot be performed.
Normally, it w ill automatically be deleted if you w ait for a short amount of time. How ever, you can also delete it using the follow ing procedures.
Startup the M S-DOS prom pt.





For Window s 98 Second Edition
Startup the MS-DOS prompt from Start, Programs, then MS-DOS Prompt.



For Window s M e
Startup the MS-DOS prompt from Start, Programs, Accessories, then MS-DOS Prompt.



For Window s 2000
Startup the Command Prompt from Start, Programs, Accessories, then Command Prompt.
Type "arp -d 10.0.0.1" and pres s the Ente r k e y.
This w ill delete the old entry to 10.0.1.1.

Sym ptom 2
Sw itching to the Access Point that is connected fails and the electric w ave reception status becomes out of range. HANDLING
Confirm the follow ing items.
1.

Is the Access Point operating correctly?

Are the pow er supply, ISDN Router or the cable modem and analog telephone lines correctly connected?

Have the Access Point settings been changed?

Page 42

Has the WEP Key (Encryption Key) been changed? Refer here for detailed explanations.

Perform the follow ing if the sw itch fails despite the Access Point operating normally.
5.

Se le ct the Acce s s Point again w ith the Wire le s s Pale tte and click OK.

Confirm w he the r or not it sw itche s .
If sw itching still continues to fail, either perform the above operations again or return it to w here it originally w as and try to reconnect to that
Access Point.

Othe r com pute rs that are conne cte d to the s am e LAN ope rate poorly afte r conne cting the Acce s s Point.
Sym ptom
There are cases in w hich it is not possible for a client computer that is connected to the same LAN to connect to the Internet after starting to use the
Access Point previously connected to a LAN.
HANDLING
Is the DHCP server operating on the LAN? Also, check the connection settings for the Wireless LAN Access Point. Is it set to Phone mode or to Local
Only mode?
Regarding these modes, the Access Point functions as the DHCP server for the Ethernet side and in the default settings, the IP addresses from 10.0.1.2
to 10.0.1.17 are assigned to the clients. For that reason, the follow ing connections exist.
1.

The Access Point responds to the client PC IP address request before responding to the LAN's regular DHCP server.

If the IP address assigned by the Access Point does not match the LAN IP address, that client does not exist on the LAN.

Therefore, it is not possible for the client to check their mail or to access the Internet.
When connecting the Access Point to the company's existing LAN line, refer here for details.
In the meantime, you can remove the Access Point from the LAN and re-acquire the client computer's IP address. Refer here for details on how to
acquire the IP address.
Changing the IP addres s s e tting of the Acce s s Point dis able d com m unications from the com pute r.
The IP address may not match the Access Point and the computer. Try either of the follow ing:
1.

Re -s e le ct the Acce s s Point in the Tool Box w indow of the Wire le s s Pale tte .

Re s tart the com pute r.

Re m ove and re -ins e rt the Wire le s s LAN PC Card.

Unde r w hat circum s tance s do I nee d to change the w ire le s s channe l that the Acce s s Point us e s ?
If the communication rate is very slow , there may be another active Access Point, an active third-party w ireless access point, or an active w ireless
station nearby, causing radio interference. Changing the w ireless channel reduces the radio interference and improves the communication rate.
The condition of the conne ction on the cable Ethe rne t s ide has w ors e ne d s ince the PCWA-A100 Wire le s s LAN Acce s s Point w as conne cte d
to m y LAN. I cannot acce s s the Inte rne t.
Check the Access Point configuration for the connection mode. Phone or Local Only mode may be assigned. When using the Phone or Local Only
connection modes, the Access Point serves as the DHCP server for the Ethernet LAN and assigns IP addresses from 10.0.1.2 to 10.0.1.17 to client
computers by default.
Change to Cable Modem or LAN connection mode.
M y Acces s Point is conne cte d in the Cable M ode m m ode to the Ethe rne t LAN. File and printe r s haring is available on the w ire le s s
ne tw ork but I cannot acce s s a com pute r or printe r on the Ethe rne t LAN.
In the Cable Modem mode, the LAN Access Point serves as a NAT router betw een the Ethernet and w ireless netw orks, w hich does not allow file
sharing and access beyond either netw ork.
The ISDN Router mode is recommended if the Access Point is connected to the Ethernet LAN environment such as a corporate netw ork.
I cannot control the dial-up conne ction from a com pute r on the Ethe rne t ne tw ork .
Not supported.
I w ant to conne ct to m ultiple Acce s s Points .
You can register up to four Access Point connection settings w ith the Wireless Palette. This w ay, you can sw itch connection from one PCWA-A100
Wireless LAN Access Point to another w ithout being troubled w ith reconfiguration each time you change the destination. How ever, you cannot connect
simultaneously to multiple Access Points.
I w ant to conne ct m ore than 16 clients to the Acce s s Point.
Reset the number of clients to connect using the Custom Access Point Setup Utility.
You can set up to a maximum of 49 clients, but w e recommend 16. As the number of clients increases, the accessing speed generally decreases.
Is the re a function for com m unication betw e e n tw o Acce s s Points ?
You cannot communicate betw een Access Points.
Why is it not pos s ible to conne ct e ve n though it is w ithin 100 m (330 fe e t)?
Be aw are that there are differences in the distances that electric w aves w ill reach their target depending on the location of the setup and the
surrounding conditions.
Generally, the ultimate distance w ill decrease if there are metallic w alls in the area because of the random reflecting of the electric w aves.
It is not pos s ible to dialup from othe r com pute rs on the Ethe rne t conne ction.
This cannot be handled.
Whe n in the te le phone line conne ction m ode , I cannot connect to the Inte rne t w ith a baud rate of 56Kbps .
56Kbps is the maximum baud rate.
Depending on the telephone line, the baud rate may not be as much as 56Kbps.
Can I use it w ith Blue tooth?
The Wireless LAN that conforms to IEEE802.11b, has a shock recovery function similar to that of the normal Ethernet.
In contrasts, Bluetooth does not have such a function mounted.
Therefore, if you use both products close together, the product that conforms to IEEE802.11b w ill possibly monopolize the bandw idth.
To avoid such an occurrence, separate the tw o products for use.
Doe s this corre s pond to call-back?
Currently, it does not correspond.
Is it pos s ible to conne ct to the Window s NT RAS s e rve r?
No.
Is the re an e ncryption function?
This supports the 40-bit encryption function that conforms to IEEE802.11.
Is it dangerous to us e this ne ar a m icrow ave ove n?
No, it is not dangerous.
Microw ave ovens also, like the Wireless LAN products that conform to IEEE802.11b, operate w ith a frequency band of 2.4 GHz.
For that reason, if you use it near a microw ave oven, the baud rate w ill decrease if you use a microw ave oven radar at the same time.
This can be said of all products that conform to IEEE802.11b.
Data trans m is s ion s pe e d is s low .



Is there any Wireless LAN Access Point (including other company products) being used near the Access Point? If so, it is possible that they are
interfering w ith each other.
Set the w ireless channel using the Access Point Setup Utility.



Is the Access Point being accessed by several clients at the same time?
Try again after w aiting for less crow ded conditions.
Page 46
Is it pos s ible to roam ?

The PCWA-C100 Wireless LAN PC Card can handle roaming.
Because the Access Point is for the home, it does not have a roaming function. When there are multiple Access Points, you can sw itch them using the
Wireless Palette.
Is it pos s ible for s e curity protection and filte ring of a M AC addre s s ?
No, these are not supported.
Why is the transfe r inte rrupte d w he n trans fe rring M PEG2 data?
11 Mbps is the logic value of IEEE802.11. The actual rate is thought to be betw een 4 and 5 Mbps.
This occurs w ith products that conform to IEEE802.11b. Accordingly, bandw idth is sometimes insufficient for transferring MPEG2's high rate stream.
Doe s this have a Ne tBIOS filtering function?
No, it does not.
Can this be us e d to rece ive te le phone calls?
No, it cannot.
It is w ritte n that if othe r w ire le s s s tations are ope rating, there w ill be e le ctric w ave
inte rfe re nce but w hat is anothe r w ire le s s s tation?
Amateur w ireless stations and w ireless LAN products that correspond to IEEE802.11b.
This is not a w ireless station, but if used near a microw ave oven, the baud rate w ill decrease w hen the microw ave oven is used at the same time.
Nothing w as dis playe d w he n I che ck e d the log w ith the Sys log Utility w he n the dialup
conne cte d to the Inte rne t s e rvice provide r via the Acce s s Point.
It is not possible to display anything because it is processing syslog messages w ith the accessory application Wireless Palette.
So, instead, it is possible to check the status display on the Wireless Palette. Check the status of the Wireless Palette that is started up or the
Speed/Status display field in the Wireless Palette details display screen and position your mouse cursor over the telephone icon in the task tray.

Note
Connecting the Access Point in the Phone mode to an existing LAN, such as in your office, must never be done. The reason is that the Access Point acts as the
DHCP server for the Ethernet so if your existing LAN already has a DHCP server, there w ill be conflicts. Refer here for details.

Dialup connect and disconnect
You can use the Wireless Palette to connect and disconnect the dialup. Therefore, you cannot control from the computer connected by the Ethernet.
Autom atic dis conne ct function of the dialup
The automatic disconnect function of the dialup automatically disconnects the telephone w hen there is no communication of packets over a predetermined amount
of time (tw o minutes at the default setting). This function is to prevent unintentionally long connections.

Hint
Normally, if there is no action taken by the client (such as receiving or sending mail or brow sing the Web), there is no interaction of packets but rarely is there
transmission of packets from the Internet side to a computer.
There are cases in w hich if packets are being transmitted to the computer regularly, the automatic disconnection w ill not function.
To prevent accidents, do not rely completely on the automatic disconnection function. When transmission is complete, it is necessary for you to disconnect the
phone yourself.
To Conne ct button
The Access Point w ill not accept the connection command for approximately one minute after manually disconnecting.
This is the same for other clients that are connected to the same Wireless LAN Access Point.

Hint
The Cable Modem mode is the safest to connect the Access Point to an existing LAN, such as in your office. The reasons are below .



The Access Point does not act as the DHCP server for the Ethernet (meaning that it does not cause a conflict even if there is a DHCP server on the existing
LAN)



Regardless of the status of the upstream interface (Ethernet interface), the IP address can be allocated according to the DHCP server function for the

Hint
Because it is possible w ith the LAN mode for clients on the Ethernet side and the Wireless Netw ork side to share files and printers and to access each other, it is
the most convenient mode for connecting the Access Point to an existing LAN such as in your office.
How ever, in the default settings of the LAN mode, the Access Point functions as the DHCP client for the Ethernet side. For that reason, it is not possible to acquire
the IP address if another DHCP server is not operating w ith a LAN connecting the Access Point. In that case, communications betw een the Access Point and the
Wireless client are not established so settings for the Access Point are impossible. (Refer here for details.)
Ethe rne t cable s that can be us e d
Either using a cross cable or a straight cable differs according to the ISDN Router that you are using. Use the same type of cable that is connected betw een your

Also, w e w ould like to decline any questions regarding that.
I w ant to control the dialup from m y iBook .
Control of connecting and disconnecting the dial up is performed by the Wireless Palette.
Therefore, it is not possible to control from an iBook.
Will it conne ct to the AirStation m ade by M e lco?
We believe that it is possible to connect, though w e do not guarantee operation.
In this case, it is considered that computers installed w ith this system's Wireless LAN PC Card can access a w ireless/cable netw ork that is configured
w ith AirStation.
Regarding accessing of the Internet or the sharing of files and printers, it is considered possible depending on the settings of the AirStation. If the
AirStation is set once using the Melco softw are, it is possible to set the AirStation using a brow ser even from a computer that is installed w ith this
system's Wireless LAN PC Card.
Also, w e w ould like to decline any questions regarding that.

Note
The AirStation is set to 14 w ith the default settings of the Wireless channel. When using it, change the AirStation channel settings from 1 to 11 using a
computer that can set the AirStation.
The nam e of the PC is not dis playe d on the Wire le s s Pale tte but anothe r com pany's card that I us e conform s to IEEE802.11b.
When using another company's card, the guarantee of operations may not match. Use the dedicated PCWA-C100 Wireless LAN PC Card.
Curre ntly, the follow ing ISDN Routers have e xpe rie nce in connection.

Glossary
Channel number
Frequency used for w ireless communications.
Wireless communications are available only among client computers and Access Points that use the same channel.
Client
Computer on a w ireless LAN. It may be called a client computer as w ell.
DHCP (Dynamic Host Configuration Protocol)
A system that automatically assigns an IP address to computers.
Netw orks that use the TCP/IP protocol, such as the Internet, use a set of numbers like 192.168.0.1 (IP address) to identify a computer.
How ever, it is time-consuming to assign an IP address to every single computer. With the DHCP server, you can assign multiple IP addresses to it and let
it assign an IP address to client computers.
DNS (Domain Name System)
A system that automatically assigns an IP address to computers.
Netw orks that use the TCP/IP protocol, such as the Internet, use a set of numbers like 192.168.0.1 (IP address) to identify a computer.
How ever, it is time-consuming to assign an IP address to every single computer. With the DHCP server, you can assign multiple IP addresses to it and let
it assign an IP address to client computers.
Encryption Key
Key used in the IEEE802.11-compliant security system (WEP).
Using the Encryption Key as the passw ord, only client computers and Access Points that have the same ID and passw ord may log onto the same
w ireless LAN for file sharing.
LAN (Local Area Netw ork)
A netw ork w hich is accessible only to its members, unlike the Internet w hich is open to an unlimited number of people.
A LAN may be built for different purposes. For example, you can build an office LAN that is accessible only to members of the same department or a
home LAN that is accessible only to family members.
WAN (Wide Area Netw ork)
Netw ork that interconnects remote LANs through the Internet or telephone lines.
