Troubleshooting 125

A5 Verify whether the AP has been properly connected to the network.

Verify whether the network is operating normally by connecting the wired net-

work cable, which has been connected to the AP, to your computer.

A6 Check the network key settings (encryption key).

When automatic code conversion (a passphrase function) has been selected and

data communication is not functioning even with a normal wireless connection,

it is recommended entering the network key (encryption key) manually.

Check the AP settings as follows. (The following is recommended for a standard envi-

ronment and thus may differ according to the specific wireless network environment.)

- When several APs are present simultaneously, check the channel setting for

each AP. When different APs are using nearby channels, interference may occur

between electronic waves. Set the APs' channels further apart from each other.

(Ex: Ch1, Ch5, Ch9, Ch13)

- When an AP's SSID (Service Set ID) option is set to "Hide", you cannot search for

that AP on the computer. We recommend canceling the "Hide" option for an AP. The

SSID is a name for distinguishing one wireless LAN from another wireless LAN.

- It is recommended using Long Preamble. Preamble is a signal for data transmis-

sion synchronization. Short Preamble may be supported by some types of APs

but may cause compatibility problems.

- It is recommended using a static IP.

- Since static channel selection is more reliable than auto channel selection, it is

recommended setting a static channel.

Q5 In the Windows XP 'Available wireless networks' window, the Wireless Net-

work Connection is displayed as 'Not Available'.

A1 Check if the wireless LAN is turned on.

Check if there is additional program for a wireless LAN connection installed.

Windows XP supports wireless LAN connections through the Wireless Zero Con-

figuration (WZC) service. Therefore, an additional program for wireless LAN

connection is not required, unless the network requires a specific program. How-

ever, installation of some wireless LAN related programs may sometimes disable

the [View Available Wireless Networks] window supported by WZC service. Exit

the wireless LAN related program then check whether the window is enabled.

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 right-click over the network adap-

tor and select 'Enable' after a short wait to check that the device is operating properly.
