Case 1 Cannot connect to the Internet

The connection between the computer and Access Point or the link between the Access Point and Internet Service Provider (ISP) may not be established.

1Check wireless link between computer and Access Point.

■Under the “Status” tab in Wireless Panel, is the Network Name shown as “Not Connected” ?

z Hints

• If the connection was established with a wrong encryption key (WEP key), the icon in the system tray may still indicate “Connected”. (If connection to an Access Point

for which encryption is enabled was attempted with encryption set to Off, or vice versa, the connection will not be completed and the “Not Connected” icon will be

shown in the system tray.)

• If the IP address shown in Wireless Panel under the “Status” tab starts with “169.254. ...” or is “0.0.0.0”, there may be a mismatch in the data encryption settings. Correct

the settings as described below. If the IP address does not start with “169.254. ...” and is not “0.0.0.0”, communication between the computer and the Access Point is

normal. Consult the section “ Check wireless link between Access Point and Internet Service Provider (ISP)”.3

1Check the data encryption (WEP) setting at the Access Point to which you want to connect.

2Click the “Network List” tab in the Wireless Panel.

3Modify the settings for the network shown as “Not Connected”, and reconnect.

• Windows Me, Windows 2000

1Select the wireless network to which you want to connect, and click “Edit”.

The “Registering Network” dialog box appears.

2Change the settings according to the settings at the Access Point, and click “Connect”.

z Hint

You can display the “Registering Network” dialog box by selecting “Dialog Format” on the “Setting” tab. If you select “Wizard Format”, follow the instructions

of the wizard to change settings.

The computer connects to the Access Point with the new settings.

• Windows XP

Under Windows XP, the setting is made in the “Connect to Wireless Network” dialog box. For details, refer to the “Operating Instructions”.

4Click the “Status” tab in the Wireless Panel and verify that the IP address does not start with “169.254. ...” and is not

“0.0.0.0”.

The connection between computer and Access Point should now be normal.

z Hint

Access Point settings can be changed from the computer only after the connection between computer and Access Point has been established properly. If unable to

connect to the Internet, perform the above steps first, to ensure that communication between computer and Access Point functions normally.

■Network Name indication does not show “Not Connected”, but IP address starts with “169.254. ...” or is

“0.0.0.0”?

There may be a mismatch in the data encryption settings. If connection to an Access Point for which data encryption is enabled was attempted with a

wrong encryption key (WEP key), the Network Name will be shown under the “Status” tab of the Wireless Panel, but the actual connection is not

established, because no IP address could be obtained (the IP address is shown as “169.254. ...” or “0.0.0.0”).

Enter the correct encryption key (WEP key) as described in 1 above, and reconnect.

2Is wireless link set up to act as network bridge? (Windows XP only)

Check this as follows.

1Click “Start”, point to “Connect To”, and click “Show all connections”.

2Confirm that the wireless network connection in question is not acting as a network bridge.

3If the wireless network connection is configured as a network bridge, right-click the corresponding icon, and click “Delete”.

3Check wireless link between Access Point and Internet Service Provider (ISP).

Refer to connection information provided by your ISP to configure the Access Point. For details, contact technical support of the ISP. Sony does not

provide any support regarding this issue.

Case 2

Cannot open the Access Point home page (setup

page)

1The “AP Setting” button under the “Status” tab of the Wireless Panel can only be used in

conjunction with the Access Point PCWA-A500 (as of February, 2003).

2Even when using the Access Point PCWA-A500, clicking the “AP Setting” button results in the

message “There was no response from the access point. Possible reasons include: the access

point is located too far away, the access point may not be configured to respond, the access

point may be turned off.”. In such a case, communication may be instable.

Check whether the distance between computer and Access Point is not excessive, and whether there are any obstacles that may impair signal

transmission. Ensure that the computer and Access Point can communicate and then click the “AP Setting” button again.

3When using Windows XP, opening the Access Point home page (setup page) may not be

possible if the Internet Connection Firewall function has been enabled.

Use the following procedure to check the firewall setting.

1Click “Start”, point to “Connect To”, and click “Show all connections”.

2Right-click the Wireless Network Connection icon to which you want to connect, and click “Properties”.

3Click the “Advanced” tab and (if selected) deselect the “Protect my computer and network by limiting or preventing

access to this computer from the Internet” check box.

4Click “OK”.

z Hint

Refer to Windows XP Online Help for details about the Internet Connection Firewall.

Note

Take appropriate precautions to ensure security when the “Internet Connection Firewall” function is disabled. Except when configuring the Wireless LAN Access

Point, it is strongly recommended that you enable the Internet Connection Firewall function at all times.

Case 8 Playback of MPEG2 streaming contents (4 Mbps,

8 Mbps) is jerky and there are dropped frames

When using 802.11b wireless LAN

Because the actual throughput in a 802.11b wireless LAN is about 4 Mbps, MPEG2 streaming data cannot be played. Use a 802.11a wireless LAN.

802.11a wireless LAN is used, but there are still dropped frames

Check the following points.

1Are multiple computers using a single Access Point simultaneously for streaming data

playback?

The actual throughput in a 802.11a wireless LAN is on the order of 17 - 20 Mbps (depending on environment). Under optimum conditions, such a

network can support MPEG2 (8 Mbps) streaming playback for up to two computers. For best results, simultaneous playback with multiple computers

should be avoided.

2Contents server and Access Point are connected by wireless link

If the contents server and Access Point are connected by wireless link, a situation similar to above occurs. When using the Wireless LAN Access1

Point PCWA-A500, connect the Network 2 connector with a cross-wired cable, as shown below.
