Sony PCWA-DE80 User Manual

If communication cannot be established with the current IP address of the computer connected to the
Wireless LAN Converter and the IP address of the Wireless LAN Converter, the dialog box above
appears.
Verify that the IP address of the Wireless LAN Converter is acceptable, and click “Execute Setup”.
The IP address of the Wireless LAN Converter is temporarily changed so that the computer can open
the Wireless LAN Converter Setup Page.

If the computer connected to the Wireless LAN Converter is also connected to another network, make sure that the
new IP address does not duplicate the address of a device on that network.

z

When you turn off or restart the Wireless LAN Converter, the IP address reverts to its original setting.

1

Disconnect and reconnect the power cord of the Wireless Unit cable to restart the
Wireless LAN Converter.

Start the Converter Setup Utility.

In the “IP Address Setup” dialog box, replace the current Wireless LAN Converter IP
address with an unused address, and then click “Execute Setup”.

2

Make sure that no proxy setting is enabled for the IP address of the Wireless LAN Converter.
For details, see case 14.

The “WEP Key” text box is only available if the “Enabled” setting is selected for “Encryption (WEP)”.
Set “Encryption (WEP)” to “Enabled”, select the “Key Length” and “WEP Key Type”, and then enter
the encryption (WEP) key in the “WEP Key” text box. The prescribed length of the string depends on
the “Key Length” setting. Check the indication above the text box.

Even if the network name (SSID) is correct, if the security settings are incorrect, communication with
the access point is impossible. Verify your access point security settings, and change any Wireless LAN
Converter security settings accordingly.

If the network name (SSID) or security settings are changed, the Wireless LAN Converter settings must
also be changed to match these new settings. Refer to “If You Change the Access Point Settings” in the
Quick Start Guide to change the settings of the Wireless LAN Converter.

When setting up the access control of the access point, input the MAC address of the Wireless LAN
Converter, and then the MAC address of the device connected to the Ethernet. The Wireless LAN
Converter first connects with its own address, then switches to the one of the wireless communication
devices. Some printers require that you set both addressed to be able to connect to them.

You cannot connect wireless PC cards that only support 2.4 GHz to a 5 GHz wireless network.

Click “Start”, and then click “Control Panel”.

In “Control Panel”, click “Network and Internet Connections”, and then click
“Network Connections”.

z

If “Network and Internet Connections” does not appear, click “Switch to Category View” on the left.

In the “Network Connections” window, right-click the Wireless Network Connection
icon that you want to use, and click “Properties”.

Click the “Advanced” tab and (if selected) clear the “Protect my computer and
network by limiting or preventing access to this computer from the Internet” check
box.

Click “OK”.

z

Refer to Windows XP Help for details about the “Internet Connection Firewall” function.

Make sure that you take appropriate security measures when the “Internet Connection Firewall”
function is disabled. Except when configuring the Wireless LAN Converter or access point, it is strongly
recommended that you enable the “Internet Connection Firewall” function at all times.

■

Antivirus scanning and network security software sometimes includes a function called a
“personal firewall”, intended to prevent unauthorized access by other computers. Depending on
the software, the security level of this function may initially be set to a high level. If this high
security level setting is left enabled, other computers may be unable to access your computer. This
can cause problems such as not being able to connect to the network when changing the Wireless
LAN Converter or access point settings. In this event, lower the security level to allow the
network connection. Refer to the software instructions or Help for details.

• Make sure that you take appropriate security measures.

• For questions about firewall functions, contact your firewall software manufacturer.

When the Windows XP “Internet Connection Firewall” function is enabled, it may prevent the
computer from being accessed externally (this function is disabled by default). This function can
prevent connection to your network when you change your Wireless LAN Converter or access
point settings. If this happens, disable the “Internet Connection Firewall” function as described
here, connect to the network, and then re-enable the function.
