Troubleshooting Guide
This document provides solutions to common problems
encountered with the Wireless Broadband Router.
Please refer to this guide before contacting Sony
Customer Information Services.
The PCWA-AR800 consists of:
• Broadband Router Unit PCWA-R1
• Wireless LAN Access Point PCWA-A820
In this document, we refer to the Broadband Router Unit as the
Router Unit and to the Wireless LAN Access Point as the Access
Point.
The PCWA-AR800 can be used at frequency settings of 2.4 GHz
and 5 GHz. Change this setting as necessary. (By default, the
PCWA-AR800 is set to 2.4 GHz.)
Preparations
Case 1 No communication between the computer and
Wireless Broadband Router
1 Are you attempting to establish a connection at a frequency
of 5 GHz?
The default wireless broadband frequency setting is 2.4 GHz. If you want to establish a wireless
connection at 5 GHz, access the Access Point Setup page through a wired network, and change
the frequency setting to 5 GHz (802.11a). Refer to the separate Quick Start Guide for details about
how to display the Access Point Setup page.
2 Was your computer properly configured for wireless
communication?
When using the Access Point functions under factory default settings, configure the computer as
follows.
The factory default settings of the Access Point function are:
• Network Name (SSID):
The 6-character identifier printed on the label inside the rear cover of the Wireless Unit
z Hint
For details about the location of the network name (SSID), refer to procedure 3 of the Quick Start Guide.
• Security settings
Encryption (WEP): Disabled
• IEEE 802.11 Mode: 11g, 11b (High multicast rate)
With the Windows Me and Windows 2000 operating systems, perform setup as described in the
documentation provided with your Wireless LAN PC Card.
With the Windows XP operating system, proceed as follows.
1
Click “Start”, and then click “Control Panel”.
2
In “Control Panel”, click “Network and Internet Connections”, and then click
“Network Connections”.
z Hint
If “Network and Internet Connections” does not appear, click “Switch to Category View” on the left.
3
In the “Network Connections” window, right-click the icon of the wireless network to
which you want to connect, and click “View Available Wireless Networks”.
4
In the “Connect to Wireless Network” dialog box (with Windows XP SP1, the
“Wireless Network Connection” dialog box), select the Access Point from “Available
Wireless Networks”, and click “Connect”. (When using the Access Point functions
under factory default settings, check the 6-character identifier printed on the label
inside the rear cover of the Wireless Unit.)
3 Are the network name (SSID) and security settings configured
correctly?
To connect to the Access Point, the network name (SSID) and security settings must be the same
at the computer and the Access Point.
z Hint
When using the Access Point functions under factory default settings, use the settings listed in 2 above.
With the Windows Me and Windows 2000 operating systems, verify the Access Point network name (SSID)
and security settings of the wireless LAN PC card as described in its documentation.
With the Windows XP operating system, proceed as follows to verify the settings.
1
Open the “Connect to Wireless Network” dialog box (with Windows XP SP1, the
“Wireless Network connecion” dialog box) as described in 2 above.
2
Select the network name (SSID) of the Access Point from “Available Wireless
Networks”.
3
Make sure that the security settings of the Access Point match those of the
computer.
4
Click “Connect”.
If the connection is not established, reset the Access Point functions to the factory default
settings as described in “Miscellaneous”, “Case 1: Forgot settings”, and then set up the
Access Point functions again as described in the separate Quick Start Guide.

4 Can the IP address of the computer be acquired?
With the computer setting “Obtain an IP address automatically” enabled, perform the following
steps. For information on how to set the IP address of the computer, see Windows Help.
Windows Me operating system
1
Click “Start”, and click “Run”.
2
In the dialog box used to specify the file name, enter “winipcfg” (exclude the
quotation marks) and click “OK”.
3
From the list in the “IP Setup” dialog box, select the Wireless LAN interface that you
are using (PC card, computer internal wireless LAN, etc.).
4
Make sure that an IP address is shown in the “IP address” text box.
5
If the IP address is “0.0.0.0” or an address starting with “169.254.” is displayed, click
“Release”, and then “Renew”.
Note
If an IP address starting with “169.254.” is displayed, a suitable IP address was not obtained with
“Obtain an IP address automatically” and your Windows operating system assigned an address to the
wireless LAN PC card or Wireless LAN Converter. In this condition, correct network connection is not
possible. Perform the setup again as described in the separate Quick Start Guide.
Windows 2000 and Windows XP operating systems
1
Click “Start”, point to “Programs” (“All Programs” when using the Windows XP
operating system) and then “Accessories”, and click “Command Prompt”.
2
In the command prompt window, enter “ipconfig /all” (exclude the quotation marks)
and press the Enter key.
3
Verify the IP address setting information of the Wireless LAN interface that you are
using (PC card, computer internal wireless LAN, etc.).
z Hint
The “Description” field shows the name of the Wireless LAN interface.
4
If the IP address is “0.0.0.0” or an address starting with “169.254.” is displayed,
enter “ipconfig /renew” (exclude the quotation marks) and press the Enter key.
A new IP address is assigned.
Note
If an IP address starting with “169.254.” is displayed, a suitable IP address was not obtained with
“Obtain an IP address automatically” and your Windows operating system assigned an address to the
wireless LAN PC card or Wireless LAN Converter. In this condition, correct network connection is not
possible. Perform the setup again as described in the separate Quick Start Guide.
Connections
Case 1 Cannot display the Setup Page (an error message
appears)
If entering “http://192.168.11.1/” in the address field of the Web browser does not open the Setup Page,
check the following.
1 Can the IP address of the computer be acquired?
See “Preparations”, “Case 1: No communication between the computer and Wireless Broadband
Router”, item 4.
2 Are the Access Point and Router Unit power connections
correct?
When powered properly, the Status indicator of the Router Unit is lit and the Status indicator of
the Access Point is flashing slowly.
3 Is the AC adapter power switch on?
Make sure that the AC adapter is properly connected and verify that the power switch is on.
z Hint
When the AC adapter power switch is on, the LED on the adapter is lit.
4 Is the Ethernet cable correctly connected?
Make sure that an end of the Ethernet cable is connected to a LAN connector of the Router Unit.
Connect the other end of the Ethernet cable to your computer.
z Hint
The Ethernet port of your computer is on its back panel.
5 Is the Windows XP “Internet Connection Firewall” function
enabled?
If the “Internet Connection Firewall” function is enabled, communication may not be possible.
See “Miscellaneous”, “Case 4: Computer firewall function and browser proxy settings” for details.
6 Is the Web browser of the computer used for the Wireless
Broadband Router setup configured to use a proxy server?
Make sure that there are no proxy settings enabled for the IP address of the Wireless Broadband
Router. See “Miscellaneous”, “Case 4: Computer firewall function and browser proxy settings”
