4 Check the “Sony PCWA-C150 Wireless PC Card” IP address.
If your IP address starts with “169.254...”, then the network connection has not been
established. You may have typed the WEP key incorrectly.
Reconfigure the WEP key with Client Manager. (For details, refer to the Quick Start Guide
or manual.)
■ I changed the Access Point’s operation mode or I switched to a
different Access Point, and I cannot establish the connection.
For Windows Me users, when your Access Point configuration is changed to a
different mode, make sure to update the IP address as follows:
1 From the “Start” menu, click “Run”.
2 Type “winipcfg” (without quotation marks), and click “OK”.
The IP Configuration dialog box appears.
3 Select “Sony Wireless PC Card” from the drop-down list, and click “Release”.

5 Wait until the new IP address is obtained.
■ In Peer-to-Peer mode, the signal strength is not displayed. How do I
tell whether a peer-to-peer connection has been successfully
established?
Because in Peer-to-Peer mode your computer can connect to multiple other
computers, each with its own signal strength, a signal strength cannot be
displayed.
To verify the connection in Peer-to-Peer mode, performe the following
procedures.
❑ Windows Me and Windows 2000
1 Double-click the My Network Places icon on the desktop.
2 Double-click “Computers Near Me”.
3 Press the F5 key to update.
4 Check whether your peers exist on your network.
❑ Windows XP
1 Access “My Network Places”.
2 Press the F5 key to update.
3 Check whether your peers exist on your network.
■ “Renewing IP address failed” message appears in Peer-to-Peer
mode (Windows 2000). What should I do?
“Renewing IP address failed” or “DHCP Server Unavailable: Renewing adapter”
message appears when the IP address is not obtained from the DHCP server.
If these messages appear, click “OK”. In Peer-to-Peer mode, Windows releases
the IP address, so performance is not affected.

■ I cannot access the Internet. Why?
Check the following common obstacles to Internet access.
❑ The Access Point is not connected to the Internet.
Connect the Access Point to the Internet, as described in the Access Point’s operating
instructions.
❑ The Wireless LAN PC card is not inserted into the computer.
Make sure that the PC card is completely inserted into PCMCIA slot.

established.
Use the Client Manager to check the communication status.

Configure the Access Point according to the Operating Instructions manual.
❑ The Access Point and the computer are too far apart.
Reposition the computer to within 30m (100 feet) of the Access Point, in a direct line of sight.
■ Why is the data transfer speed slow?
If your data transfer speed is extremely slow, try the following:
• Assign another channel number to the Access Point.
• There may be too many clients accessing the Access Point. Try accessing it
later.
■ Why does communication fail even when my computer is within 30m
(100 feet) of the Access Point?
The actual communication distance depends on various factors such as
installation site conditions and the presence of obstacles.
Try moving your computer closer to the Access Point.
■ My Access Point is connected to a broadband connection, but I
cannot access the Internet from my computer running Windows XP.
What’s wrong?
With Windows XP, if the “Bridge Connection” option is enabled, you cannot

1 From the “Start” menu, point to “Connect To”, and click “Show all
connections”.
The Network Connections window appears. The Sony PCWA-C150 Wireless PC Card icon
might appear as follows.
In this case, the “Bridge Connections” option is enabled for the Sony PCWA-C150 Wireless PC

Wireless PC Card icon, and select “Remove from Bridge”.
3 Right-click the Network Bridge icon, and select “Delete” from the shortcut
menu.

■ I am using the Windows XP Internet connection Firewall feature.
Does this feature affect my wireless connection?
Enabling the Windows XP Internet Connection Firewall may prevent your
computer from being recognized by your network.
If you have enabled this feature and are unable to configure your Access Point or
cannot recognize the Access Point that you would like to configure, try disabling
the Internet Connection Firewall feature, and try again to communicate with your
Access Point.
1 From the “Start” menu, point to “Connect To”, and click “Show all
connections”.
2 Right-click the Wireless Network Connection icon, and select “Properties”.
3 Select the “Advanced” tab, and clear the “Protect my computer and network
by limiting or preventing access to this computer from the Internet” check box
if it is checked.
When Windows XP is installed, the Internet Connection Firewall feature is disabled by default.
4 Connect to the Access Point.
5 Reenable the Internet Connection Firewall feature.
For more information about the Internet Connection Firewall feature, contact the Microsoft
Corporation or the manufacturer of your computer.
