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.)
PCWA-C700 What to do if...
• 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 “3 Check wireless link between Access Point and Internet Service Provider (ISP)”.

Introduction
Make sure that the supplied Wireless Panel software is installed.
When using Windows XP, wireless connection settings are made using the built-in functions of Windows XP, but the Wireless Panel software is still useful
because it allows monitoring of network status and lets you selectively turn 802.11b (2.4 GHz) and 802.11a (5 GHz) transmission on/off.
Encryption key (WEP key)
If a problem occurs, answer the following questions in sequence to find a solution.
Yes
Cannot connect to the Internet
Is the Access Point on?
Check the Wireless Panel icon in the taskbar. Was the driver
installed correctly?
: Driver is not installed or not installed correctly.
: Driver is installed correctly.
Is the IP address shown on the “Status” tab of the Wireless
Panel not starting with “169.254. ...” and not “0.0.0.0”?
No
z Hint
Turn on the Access Point.
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.
c Access Point manuals
The computer connects to the Access Point with the new settings.
Refer to “Verifying Wireless LAN PC Card driver
installation” in the “Operating Instruction” to make
sure that the driver is installed correctly. If the driver
is not installed correctly, perform the procedure
outlined in “Uninstalling the Wireless LAN PC Card
driver” in the “Operating Instructions”, and then
reinstall the driver. For details, visit
http://www.sony.com/wirelesslansupport.
If the IP address starts with “169.254. ...” or
is “0.0.0.0”, there may be a problem with
the settings for the wireless link between
the Access Point and the computer.
c Case 1 – 1 in this document
The wireless link between the computer and Access Point functions
normally.
Is the wireless link set up to act as a network bridge?
(Windows XP only)
• Windows XP
Under Windows XP, the setting is made in the “Connect to Wireless Network” dialog box. For details, refer to the “Operating Instructions”.
4
Click 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.
If it is set up to act as a network bridge,
delete the connection from the bridge list.

installed, and the Easy Setup Wizard* has
started, but the message “It appears that the
driver is not installed properly.” appears
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.
* Under Windows XP, the Easy Setup Wizard does not start automatically.
1Make sure that the computer is running Windows Me, Windows 2000, Windows XP Home Edition,
or Windows XP Professional.

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.
