(host) Using the adapter in a TCP/IP environment This section explains how to connect and test the A040/A041 on a TCP/IP network. If you do not use TCP/IP, please see Testing on a non-

TCP/IP network on page 24. Computer A (the host) and computer B should both be configured to use TCP/IP and have fixed IP addresses. Well refer to the IP address of computer A (the host) as IP-A and the IP address of computer B as IP-B. 1 2 Check and write down IP-A and IP-B. Switch off computer A (the host). 20 A040/A041 Getting Started 3 Make sure that the Access Point, computer B and the hub are operating normally. Connect the power unit to the A040/A041s power connector and to a wall outlet. Connect the Ethernet cable (Nokia A040) or USB cable (Nokia A041) to the adapters host connector. Connect the other end of the Ethernet or USB cable to the host computer. Switch on at the wall outlet. Switch on the host computer. 4 5 6 7 8 power connector host connector host computer After the host computer has powered up, the adapters power LED should glow a steady green, and its LAN LED should be on, indicating a good connection to the host computer. The adapter will start beeping as it searches for an Access Point. After a short while the beeps should stop and the adapter will emit a chirp (three rising tones) indicating that a connection has been made. Getting started 21 Note: You only need to perform this step if your network uses automatic IP address assignment (DHCP). 9 If the beeps stop but there is no chirp, and the radio and notify LEDs continue to flash together, it means that the A040/A041 is unable to find an eligible Access Point, or that the Access Point will not allow a connection. See Troubleshooting on page 25. 10 (DHCP only) When the A040/A041 has stopped beeping you should use the IPConfig utility under Windows to renew the IP address information in Computer A and Computer B (see page 23). Make a note of the IP addresses assigned for use later in the testing. 11 On Computer B, open an MS-DOS console window. 12 At the prompt, issue a ping command to the IP address of Computer A. For example, if IP-A is 192.168.5.21, you would enter:

ping 192.168.5.21 Successful ping If the ping is successful, you should see an output of the following form:

C:\> ping 192.168.5.21 Pinging 192.168.5.21 with 32 bytes of data:

Reply from 192.168.5.21: bytes=32 time=1ms TTL=32 Reply from 192.168.5.21: bytes=32 time<10ms TTL=32 Reply from 192.168.5.21: bytes=32 time<10ms TTL=32 Reply from 192.168.5.21: bytes=32 time<10ms TTL=32 C:\>

22 A040/A041 Getting Started Your A040/A041 is operating correctly, and you dont need to perform any special configuration to make it work. Unsuccessful ping If there is a problem, youll see the following output:

C:\> ping 192.168.5.21 Pinging 192.168.5.21 with 32 bytes of data:

Request timed out. Request timed out. Request timed out. Request timed out. C:\>

See Troubleshooting on page 25 for possible problems and solutions. Renewing IP address information If youre using DHCP and you need to renew the IP address information on a computer, follow the instructions in this section. Under Windows 95/98 Under Windows 95/98, you do this using WinIPcfg:

1 2 3 Choose Run from the Start menu. Enter WinIPcfg and press Return. Select the correct adapter card in the pull-

down menu. Click Release. Click Renew. 4 5 Getting started 23 Under Windows 2000/NT 1 2 Open a DOS prompt. Enter ipconfig /release This will release the old address. Enter ipconfig /renew to renew the address. 3 You should now be able to access the Access Point from your client machine. Testing on a non-TCP/IP network If you do not use TCP/IP you can still follow the instructions in Using the adapter in a TCP/

IP environment. When the A040/A041 stops beeping, indicating a connection has been made to the Access Point, you can try transferring a file between Computer A and Computer B in order to verify that the system is operating. 24 A040/A041 Getting Started Troubleshooting If the ping test fails and your host computer cannot communicate with a known station on the wired LAN, check the table below, which lists some possible problems and solutions:

If You entered the IP address incorrectly in the ping test The A040/A041 is beeping continuously You have multiple Access Points, using different Network Names Your Access Point is using WEP encryption Nokia A040: Your host computer has incorrect Ethernet drivers installed Nokia A041: Your host computer is running Windows 95 or Windows NT Nokia A041: You forgot to install the Nokia A041 USB driver software on your host computer do this Try the ping test again. Check that the Access Point is within range and functioning correctly. Decide which network name you want to connect to and configure the A040/A041 with that name. Youll need to configure the A040/A041 with the correct WEP mode and encryption keys to allow access. Install the Ethernet NIC as if you were intending to connect to a regular LAN hub. Upgrade to Windows 98 or Windows 2000 or use a different host. Install the drivers from the supplied CD-

ROM. Some solutions involve reconfiguring the adapter youll need to follow the instructions in Preparing to configure an adapter and Configuration parameters in the Advanced User Guide Getting started 25 26 A040/A041 Getting Started Index A Access Point H host connection lost 12 connection regained 12 minimum requirements 16 host connector 10, 18, 21 B beeps 12, 21 C checklist 10 chirp 12, 21 connection 12 connectors 10 conventions 5 copyright 17 D DHCP 22 F features 6 I IP address information renewing 23 ipconfig 24 IPConfig utility 22 L LAN LED 11, 21 LED special sequences 12 LEDs 11 License Agreement 18 M MS-DOS console window 22 27 N NIC 16 Nokia License Agreement 17 non-TCP/IP network 24 notify LED 11 S set-up mode accessing 13 LED sequence 13 special LED sequences 12 P ping 22 possible problems 25 power connector 10, 18, 21 power LED 11, 21 power-on LED and sound sequences 12 R radio LED 11 release 23 renew 23 IP address information 23 reset button 13 RJ45 16 RJ45 Ethernet connector 10 T TCP/IP host requirements 16 testing adapter 20 testing 20 U USB connector 10 driver software 16 USB driver software 17 Utilities CD-ROM 17 W WinIPcfg 23 28 A040/A041 Getting Started

Do not connect incompatible products. 3 Using this document The Wireless LAN Adapter is approved to create a wireless LAN network to send data and e-mail messages, to browse on the Internet, and to establish connections with other computers. Data connections can be made from most locations where your Wireless LAN Adapter operates. However, it is recommended that you move the Wireless LAN Adapter to a location where the strongest possible network signal can be obtained. When the signal is strong, data transmission is efficient. The following factors may impair wireless connections:

Noise Radio interference from electronic appliances and equipment, as well as from other wireless devices in areas where wireless devices are prevalent. Handover As the Wireless LAN Adapter user moves from one network cell to another, the signal strength of the channel drops and the network may hand the user over to a different cell and frequency, where the signal is stronger. A cell handover may also occur when the user is stationary due to varying network traffic loads. Electrostatic discharge A discharge of static electricity from a finger or a conductor may cause erroneous functions in electric devices. The discharge may result in unstable software operation. Network connections may become unreliable, data may be corrupted, and the transmission halted. In this case, end the existing connection (if any) and restart the unit by powering off and on again. Dead spots and dropouts Dead spots are areas where radio signals cannot be received. Dropouts occur when the Wireless LAN Adapter user passes through an area where the radio signal is blocked or reduced by geographic or structural obstructions. Signal impairment Distance and obstacles can cause out-of-

phase reflected signals that result in a loss of signal strength. Low signal strength Due to either distance or obstacles, the radio signal strength from a network cell may not be strong or stable enough to provide a reliable wireless connection for communication. Therefore, to ensure the best possible communication, remember to consider the following points:

Data connection works best when the Wireless LAN Adapter is in a stationary position. Do not place the Wireless LAN Adapter on a metal surface. 4 Nokia A040 WARNING!

Do not use the Wireless LAN Adapter when the use of a wireless LAN terminal is prohibited or when it may cause interference or danger. Use only the region setting appropriate for the area where the Wireless LAN Adapter is used at the present time. Using the Wireless LAN Adapter in any other region or with an incorrect region setting may be illegal. Use only accessories approved by Nokia for use with this particular Wireless LAN Adapter.

The personnel there will assist you and, if necessary, arrange for service. 6 Nokia A040 Operating environment Remember to follow any special regulations in force in any area and always power off your Wireless LAN Adapter whenever it is forbidden to use it, or when it may cause interference or danger. When connecting the Wireless LAN Adapter or any accessory to another device, read its user's guide for detailed safety instructions. Do not connect incompatible products. As with other mobile radio transmitting equipment, users are advised that for the satisfactory operation of the equipment and for the safety of personnel, it is recommended that the Wireless LAN Adapter should only be used in the normal operating position. Electronic devices Most modern electronic equipment is shielded from radio frequency (RF) signals. However, certain electronic equipment may not be shielded against the RF signals from your Wireless LAN Adapter. Pacemakers Pacemaker manufacturers recommend that a minimum separation of 20 cm (6 inches) be maintained between a Wireless LAN Adapter and a pacemaker to avoid potential interference with the pacemaker. These recommendations are consistent with the independent research by and recommendations of Wireless Technology Research. Persons with pacemakers should always keep the Wireless LAN Adapter more than 20 cm (6 inches) from their pacemaker when the Wireless LAN Adapter is powered on. If you have any reason to suspect that interference is taking place, power off your Wireless LAN Adapter immediately. Hearing aids Some digital wireless devices may interfere with some hearing aids. Other medical devices Operation of any radio transmitting equipment, including a Wireless LAN Adapter, may interfere with the functionality of inadequately protected medical devices. Consult a physician or the manufacturer of the medical device to determine if they are adequately shielded from external RF energy or if you have any questions. Power off your Wireless LAN Adapter in health care facilities when any regulations posted in these areas instruct you to do so. Hospitals or health care facilities may be using equipment that could be sensitive to external RF energy. Posted facilities Power off your Wireless LAN Adapter in any facility where posted notices so require. Potentially explosive atmospheres Do not use your Wireless LAN Adapter when in any area with a potentially explosive atmosphere and obey all signs and instructions. Sparks in such areas could cause an explosion or fire resulting in bodily injury or even death. Users are reminded of the need to observe restrictions on the use of radio equipment in fuel depots (fuel storage and distribution areas), chemical plants or where blasting operations are in progress. 7 Areas with a potentially explosive atmosphere are often but not always clearly marked. They include below deck on boats; chemical transfer or storage facilities; vehicles using liquefied petroleum gas (such as propane or butane); areas where the air contains chemicals or particles, such as grain, dust or metal powders; and any other area where you would normally be advised to turn off your vehicle engine. Failure to observe these instructions may lead to legal action. 8 Nokia A040 Regulatory information The Nokia Wireless LAN Adapter conforms to the following European directives:
