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 If you are using a network key (encryption key), an AP (Access Point) and a
computer-to-computer network (peer-to-peer), you have to use the same network
key. The network key of the AP is configured in the AP management program.
Ask your network administrator for more detailed information.
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 there is a configured bridge connection between the network adapters.
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.
Q4 I cannot connect to the AP wireless network.
A1 Check the wireless LAN radio environment. Using a wireless LAN may be
restricted by the surrounding radio environment, and the distance between
wireless stations. Also obstacles such as walls or doors may affect wireless LAN
connections.
A2 Check that the AP is operating properly. Turn the AP off, and turn it on after a
short wait.
A3 Check that the network key (encryption key) configuration for the AP is correct.
Q5 In the Windows XP 'Available wireless networks' window, the Wireless
Network Connection is displayed as 'Not Available'.
A1 Check that the specific program for a wireless LAN connection is installed.
Windows XP supports wireless LAN connections through the Wireless Zero
Configuration (WZC) service. Therefore, an additional program for a wireless
LAN connection is not required. However, installation of the specific program
for a wireless LAN connection may disable the 'Available wireless networks'
window of the Wireless Network Connection supported by WZC service in
certain cases. Exit the program and try again.
A2 Initialize the device driver.
