Cannot connect to the Internet after changing the
access point settings
If you have changed the data encryption setting of the access point according to its documentation, you must change the wireless connection settings at the
computer accordingly, using the same values as for the access point.
If Internet access was working and has become unavailable after changing the encryption settings, perform the following steps to match the settings of the
computer and access point.
The access point encryption settings were changed, but the settings for the link between the
access point and computer were not modified.
Follow the instructions for "Case 1 – 1 Check the wireless link between the computer and access point" and modify the settings of the computer to
match the access point settings.
The access point encryption settings were changed, and the settings for the link between the
access point and computer were also modified.
Has the encryption key been input correctly?
Temporarily return the access point settings to their defaults as described below, and then reconfigure the access point.
Follow the instructions in the access point documentation to reset the access point to its defaults.
Establish the wireless link between the access point and computer.
If communication between the access point and computer is normal at this stage, the access point can be configured.
Configure the access point for access to the Internet via an Internet service provider (ISP).
If required, change the network name (SSID) of the access point. For security reasons, data encryption for the access point should be configure the
Do not forget the encryption key.
If the network name (SSID) or data encryption settings of the access point were changed in step 3, configure the
computer with the same settings.
When you change the access point settings, communication between the access point and computer will be interrupted. If you have changed settings at the access point,
be sure to reconfigure the computer with the same settings.
When attempting to connect to the access point
with the Easy Setup wizard, the "Wireless LAN
PC Card not inserted" message appears.
Make sure that the computer is running the Windows 2000, Windows XP Home Edition, or
Windows XP Professional operating system.
This product does not support the Windows 95, Windows 98, Windows Me, or Windows NT 4.0 operating system.
Has the driver been installed correctly?
To verify that the Wireless LAN PC Card driver has been installed properly, perform the following procedure.
Right-click "My Computer", and click "Properties" on the menu. The "System Properties" dialog box appears.
On the "Hardware" tab, click "Device Manager".
Windows 2000 operating system
Double-click "Network adapters" and check "Sony 802.11a/b/g Wireless LAN Adapter".
• If an "X" or "?" symbol is shown before "Sony 802.11a/b/g Wireless LAN Adapter", the driver was not correctly installed. Proceed to step 4.
• If you cannot locate "Sony 802.11a/b/g Wireless LAN Adapter", double-click "Other devices" and verify whether you can find "Ethernet
controller". If you do, proceed to step 4.
In situations other than those described above, the driver was correctly installed.
Right-click "Sony 802.11a/b/g Wireless LAN Adapter" or "Ethernet controller", and then click "Remove" on the menu.
Refer to the "Quick Start Guide" and reinstall the driver and utility software.
In the Easy Setup Wizard, the encryption key
(WEP key) was input, but the "Next" button
remains grayed and cannot be clicked
Was the encryption key input correctly as a string of the exact length?
If the string input as encryption key (WEP key) is too long or too short, or if it contains an illegal character, the "Next" button does not become available.
Enter a string of the exact length, as indicated below.
40 or 64 bits
5 characters (alphanumeric and symbols)
104 or 128 bits
13 characters (alphanumeric and symbols)
Cannot switch networks
When using the Windows 2000 operating system
If logged on to Windows as a user with limited privileges, the network cannot be switched. Log on as a user with administrator access privileges.
When using the Windows XP operating system
If "Streaming Mode" was set to On, the wireless setting functions of the Windows XP operating system are not available. Set "Streaming Mode" to Off after
viewing streaming video data.

Even if the settings in "Channel settings to create
Ad hoc network" on the Wireless Panel are
configured, you cannot build a peer-to-peer
The Wireless Panel software "Channel settings to create Ad hoc network" settings are not, in actuality, used to build peer-to-peer networks. They are rather
an IEEE 802.11 mode used with the Windows XP operating system wireless configuration function to build peer-to-peer networks, as well as a channel
configuration function. When you configure the "Channel settings to create Ad hoc network" settings, you must also use the Windows XP operating system
wireless configuration function to build your peer-to-peer network. For details about the Windows XP operating system wireless configuration function,
refer to the Window XP operating system Help.
Playback of MPEG2 streaming contents (4 Mbps,
8 Mbps) is jerky and there are dropped frames
When using an IEEE 802.11b wireless LAN
Because the actual throughput of an IEEE 802.11b wireless LAN is about 4 Mbps, MPEG2 streaming data cannot be played back. Use an IEEE 802.11g or
802.11a wireless LAN.
Using an IEEE 802.11g or 802.11a wireless LAN, but there are still dropped frames
Check the following points.
Are multiple computers using a single access point simultaneously to stream data playback?
The actual throughput of an IEEE 802.11g or 802.11a wireless LAN is of the order of 17 to 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.
The contents server and access point are connected by wireless link
If the contents server and access point are connected through a wireless link, a situation similar to 1 above occurs. Connect to the contents server
through an Ethernet. If you are using the Wireless Broadband Router PCWA-AR300 or PCWA-AR800, use an Ethernet cable to establish the connection
as illustrated below.
To the Internet
Client modem or
to the backbone
Under the Windows XP operating system, conditions 1 and 2 above do not apply, but there are
occasional dropped frames
Set "Streaming Mode" on the "Status" tab of the Wireless Panel window to On. This temporarily suspends the Windows XP operating system wireless
configuration functions (Wireless Zero Configuration service) to optimize performance.
• When playback of streaming data is finished, do not forget to set the "Streaming Mode" button to Off. If the setting is left On, network switching is not possible.
• When you establish a connection to a network using the WPA security method, you cannot use "Streaming Mode".
Some functions and settings are not available to
