Check the AP Settings
For the AP settings, refer to the User's Guide provided by the AP manufacturer.
A3 Verify whether the environment is suitable for using a wireless LAN.
The use of a wireless LAN may be restricted according to the environment and distance. Ob-
stacles such as walls or doors affect the use of a wireless LAN. Install the AP in a high and
open space 50cm from the wall and far removed from any other radio signal sources.
A4 Verify whether the AP is operating properly.
- When the AP is not operating normally, turn off the AP and after a short while turn it on again.
- Verify whether the AP's firmware is the most recent version. (Contact the AP manufacturer
or the place where you purchased the AP for details of the AP firmware.)
A5 Verify whether the AP has been properly connected to the network.
Verify whether the network is operating normally by connecting the wired network 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 commu-
nication is not functioning even with a normal wireless connection, it is recommended entering
the network key (encryption key) manually.
A7 Check the AP settings as follows. (The following is recommended for a standard environment
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 transmission synchro-
nization. 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.
Q4 In the Windows XP 'Available wireless networks' window, the Wireless Network
Connection is displayed as 'Not Available'.
A1 Check if the wireless LAN is turned on.
A2 Check if there is additional program for a wireless LAN connection installed. Windows XP sup-
ports wireless LAN connections through the Wireless Zero Configuration (WZC) service. There-
fore, an additional program for wireless LAN connection is not required, unless the network
requires a specific program. However, 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 > De-
vice Manager > Network adapters, and select the wireless LAN adapter. Right-click the net-
work 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.
