Wireless LAN Related

For basic procedures for using a wireless LAN, refer to (P. 4-9) “Configuring the

Network Environment Settings for Wireless LAN Network (WLAN)”.

Q1 The Wireless LAN device is operating properly, but I cannot connect to the Internet or to another computer.

This is due to an inappropriate configuration. Check the following check lists:

A1 If you are using a computer-to-computer (Ad Hoc) network connection, check that the name of the configured network (SSID) is correct. The network name (SSID) is case sensitive.

A2 If you are using a network key (encryption key), you have to use the same network keys for an AP (Access Point) and a computer-to-computer network (Ad

Hoc). The network key of the AP is configured in the AP management program.

Ask your network administrator for more detailed information.

A3 Check that the device driver is properly installed. If the driver is not properly installed, you will find a yellow exclamation mark on the network icon by clicking

Start > Control Panel > Performance and Maintenance > System

> Hardware tab > Device Manager > Network adapters >

Wireless LAN adapter . If there is a yellow exclamation mark, please reinstall the device driver with the system software CD.

Q2 The signal strength is excellent, but I cannot connect to the network.

Even if the signal strength is excellent, the network connection may not operate properly if the TCP/IP properties are not properly configured, or the network key

(encryption key) is incorrect.

A1 Check that the TCP/IP properties are configured properly. When you connect to an AP, click the Wireless Network Connection icon ( ) on the taskbar and select the Support tab. If the IP is not allocated properly, the IP address will be displayed as follows. (e.g. 169.254.xxx.xxx)

If the network does not provide DHCP, you have to specify the correct IP address by asking your network administrator.

Even if the network provides DHCP, the server may not allocate an IP address to the client properly, and the client station cannot connect to the network.

A2 Referring to A2 of Q1, check that the network key is correct.

A3 Referring to Q4, check that AP is operating properly.

Chapter 7. Recovering the Computer 7-15

7-16 Manual

Q3 I cannot share an Internet connection.

A1 It may require some time to synchronize the computers to share an Internet connection after the Internet connection sharing configuration is completed. If you cannot share Internet connection even after a longer period, restart the computer.

A2 Check if the connection between the network adapters is configured to bridge.

If there is a configured bridge connection between the network adapters through the network configuration wizard, remove the network bridge, and reconfigure the Internet connection sharing.

A bridge connection is created when you ran Network Setup Wizard from the

[Network Connections] window, and selected both the internal connection adapter and another adapter in the wizard.

Q4 I cannot connect to the AP.

Checking the computer settings

A1 Check that the wireless LAN function of the computer has been enabled as follows. If the function is disabled, enable the wireless LAN function.

For Windows XP, select Start > Control Panel > Network Connections, and check that the Wireless network connection is set to ‘Enable’.

For Windows 2000:

For an 11b card, if Search Network in the Status window of the Client

Manager program does not work, select ‘Activate Wireless Network’ from the

File menu.

For an 11g card, check that the “Turn On Radio Signal” message is displayed at the bottom of the Diagnostic tab of the MagicLAN Utility. If the message is displayed, click the button to activate the Wireless LAN. If you have properly activated the function, the “Turn Off Radio Signal” message will be displayed.

If the Wireless LAN button exists, check if the Wireless LAN button is turned on. (See P.1-9 Using the Keyboard.)

A2 Click the Refresh button to search for AP°Øs again. (A link to the Refresh button is required)

A3 Check that the same network key (encryption key) is configured on both the AP and the computer. A network key is an encryption key to encrypt data between the AP and the computer and manual configuration of the network key is recommended.

A4 Move the computer to another location. As the reception quality of a radio may vary according to the location of the radio, the wireless communication quality may be affected by the location of the computer. In addition, close distances (less than 5m) between wireless equipment, especially an AP, may result in poor wireless communication quality.

A5 Check that the wireless LAN card is recognized by the computer.

“The current wireless network card driver not exist. Cannot communicate”message appears in the notification area, when the card has not been properly recognized. This may occur due to an improperly installed driver, or a wireless LAN card error. Please reinstall the driver. If you are using Windows

2000, check that the Turn on/Turn off Radio is configured to “Turn on” in the

General tab of the PROSet program.

Checking the AP settings

For procedures to configure the AP settings, refer to the User Guide supplied withthe AP.

A6 Check that the environment is appropriate for using a wireless LAN. Connecting to a wireless LAN may be affected by the environment and the distance from an

AP. Obstacles such as walls and doors affect the communications quality of a wireless LAN. Please install an AP in a high and unobstructed location away from other radio sources.

A7 Check that the AP is operating properly. If the AP is not operating properly, turn it off and then turn it on again after a short pause. Check that the latest firmware version of the AP is installed. (For detailed information on the firmware of the AP, ask your AP manufacturer or product provider)

A8 Check that the AP is properly connected to the network. Connect the network cable from the AP to the computer and check that the cable network is operating properly.

A9 Check that the network key (encryption key) is configured correctly. If data communication is not available, even though the wireless connection is normal when the Automatic password converting function (Passphrase function) is selected, enter the network key manually (encryption key).

A10 Check the settings of the AP as follows.

When there are a number of AP’s, check the channel configuration of the AP’s.

Using adjacent channels for neighboring AP’s may cause radio interference.

Configure the AP’s and avoid adjacent channels. (e.g. use Ch1, Ch5, Ch9 and

Ch13)

When the SSID option of an AP is configured to “Hide”, you cannot search for that AP An SSID (Service Set ID) is a name for distinguishing a wireless LAN from another wireless LAN.

Using long preamble is recommended. Preamble is a signal for synchronizing data transmission. Although some types of AP support short preambles, using a short preamble may cause a compatibility problem.

Using a fixed IP address is recommended.

Since fixed channel configuration is more stable than auto channel selection, fixed channel configuration is recommended.

The above recommendations are for a general environment. The settings may differ depending on the wireless network environment.

Chapter 7. Recovering the Computer 7-17

7-18 Manual

Q5 In the Windows XP ‘Available wireless networks’ window, the

Wireless Network Connection is displayed as ‘Not Available’.

A1 Check that the Wireless LAN operating LED is on. (See P.1-11 Status Indicators.)

A2 Check that an additional wireless LAN program has been installed. Since

Windows XP provides a wireless communication service using the Wireless Zero

Configuration (WZC) service, an additional wireless LAN program is not required for Windows XP. In some cases, an installed wireless LAN program configures the Available Wireless Networks window of the WZC service in Windows

XP to ‘not use’. Exit the wireless LAN program and check again.

A3 Initialize the device driver.

Click Start > Control Panel > Performance and Maintenance > System >

Hardware tab > Device Manager > Network adapters, and select the wireless

LAN adapter. Right-click the network adaptor and select 'Disable'. Then rightclick over the network adaptor and select 'Enable' after a short wait to check that the device is operating properly.

A4 Right-click the My computer icon, and select Manage. When the Computer

Management window appears, double-click Services and Applications on the left, and then click Services from the sub menu tree. Select the Standard tab in the right pane, double-click Wireless Zero Configuration and check that Startup

Type is configured to Automatic, and the Service status is Started.

Q6 The Wireless network connection operates properly, but the

Wireless Network Connection ( ) icon on the Taskbar displays the “Disconnected” message.

A This is one of the known problems when you are using a wireless LAN connection after installing Windows XP service pack 1.

For more information, refer to the following link for known problems with

Microsoft.

http://support.microsoft.com/default.aspx?scid=kb;en-us;Q328647

Q7 When connecting to a computer-to-computer (Ad Hoc) network, I cannot connect to another computer connected to the same computer-to-computer network.

A1 Click the Refresh button to search for AP’s again. (A link to the Refresh button is required).

A2 Check the TCP/IP properties of the computers to be connected through the computer-to-computer (Ad Hoc) network. All of the computers to be connected through a computer-to-computer (Ad Hoc) network should be configured so that their IP addresses are within the same subnet range.

If the IP address is configured to DHCP (Obtain an IP address automatically) in

TCP/IP properties, IP address is configured within the same subnet range automatically.

If the IP address is configured to static IP in TCP/IP properties, select Use the following IP address in the TCP/IP properties of the wireless adapter, configure IP address:10.0.0.1~10.0.0.254, and Subnet mask: 255.255.0.0, and then try again.

Q8 The network does not operate properly when both the wireless and the wired network connections are simultaneously configured with the same IP address.

A You cannot use the wireless and the wired network connections using the same IP address simultaneously. To use either the wireless or the wired network in turn with the same IP address, you have to Disable whichever network device will not be using in the network connection of the Control Panel.

Q9 The wireless LAN does not operate properly when there are other products operating in the 2.4GHz band.

A Therefore some channel interference may happen when there are other devices using the same frequency band such as a wireless video transceiver, a microwave oven, etc. If other products cause channel interference, changing the AP channel is recommended. Since the IEEE802.11g device operates in hybrid mode when there is an IEEE 802.11b device in operation, the data rate might decrease.

Q10 An established wireless LAN connection is disconnected after

2~3 minutes, and the connection is not recovered.

A1 This may be caused by channel interference. Change the channel of the AP, and reconnect.

A2 Selecting the “Use IEEE 802.1x network authentication” option in Windows XP when IEEE 802.1x authentication is not used, may cause this phenomenon.

Check the properties of the AP in the wireless network settings. If the ‘Use IEEE

802.1x authentication in this network’ option is selected, deselect the option on the Authentication tab.

For more detailed information about authentication server, ask your network administrator.

Chapter 7. Recovering the Computer 7-19

7-20 Manual

A3 If the AP is configured to ‘Use network authentication (Shared Key)’ If the AP is configured to authentication shared mode, all computers to be connected should be configured as follows:

If you are using Windows XP, select network authentication(shared mode) in the wireless network settings.

Click Start > Control Panel > Network and Internet Connections > Network

Connections. Right-click the Wireless Network Connection icon, and click View

Available Wireless Networks > Advanced. In the Wireless Networks tab, select an AP in the Available Networks field and click Configure and select ‘Network

Authentication (Shared Mode).

For Windows 2000(when an 11b card is used), check that Shared Key

Authentication has been selected in the Security settings window of the

Wireless LAN program Client Manager. For more network authentication procedures, ask your AP (Access Point) administrator.
