- When the SSID option of an AP is configured to “Hide”, you cannot search for
that AP in the computer. Canceling the Hide option of an AP is recommended.
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.
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 ”Reading the Status
Indicators” (15))
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 ‘Do 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 right-
click 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.
