In addition, this information can help to clarify issues encountered when using the SmartWi, Cingular Connection Manager and its associated features. 25 VAIO® Computer Wireless Information Answers to Frequently Asked Questions ❑ General Question: What is the SmartWi Connection Utility? Answer: SWCU is a wireless connection utility application that is designed to switch and manage wireless connection modes between Bluetooth, 802.11, and Cingular GPRS/EDGE. Question: Can I connect to two separate types of wireless connections simultaneously (for example, GPRS and 802.11b/g)? Answer: No. Connections are mutually exclusive, with the exception of Bluetooth which will run concurrently with other wireless connections. Bluetooth can be switched on and off via the software without causing interference to the current connection (for example, GPRS or 802.11b/g). The hardware indicator/switch for the wireless devices is located at the front panel on the left side. ❑ SWCU Operation Question: Why do I get a VAIO Assistant prompt when launching WLAN? Answer: If there is not any WLAN profile configured previously (this is the first time using WLAN), the VAIO Assistant will be launched automatically, or the VAIO Wireless Help Utility loads when it detects a failure in interfacing with the driver. To remedy the problem, follow the suggestions from the assist help section. Question: I clicked the “Show All Prompts” button for the Reset all messages feature, but nothing seemed to happen. What happened when I clicked this button? Answer: Clicking the Show All Prompts button for the Reset all messages feature activates all the prompts (not options) that request the “Don’t ask me again” action. Normally, when notifications appear from yes/no prompts you can select if you do not want to be asked again for the notifications by checking the “Don’t ask me again” check box. The “Reset all messages” feature provides a way to clear all the checkboxes from all the prompts simultaneously. As a result, the prompts will display again. Question: I clicked on the SmartWi minimize option and noticed the minimized icon was not in the taskbar. Where is the minimized application 26 Answers to Frequently Asked Questions and how do I bring back the application to the desktop? Answer: The SmartWi application was minimized into the Task-tray, which shows the “SWCU” icon and not into the “Taskbar”. Depending on the type of connection and combination, if any, the SWCU icon will reflect the current connection.

This should refresh Windows and provide an accurate overview of wireless status. If this is not fixed the problem, then close the Windows Wireless Network Connection window and re-launch it from Windows network connections. ❑ Cingular Connection Manager (CCM) Question: What does it mean to “Restore” from the tool help bubble? Answer: Clicking the “mini bar” option once, reduces the full details to a 27 VAIO® Computer Wireless Information “mini bar”. Click the “Restore” option to return to full details view. Question: Why does the “Connection Log” not sort when clicking on the columns title bar? Answer: This feature will be available in future versions. Sorting by type, technology, date/time, duration total bytes and description should be available in future versions. Question: Why do I see “Device not detected” in the Cingular Connection Manager details window? Answer: This is most likely to occur while switching from WWAN to launching CCM. There is a slight timing degradation that occurs while making the switch which causes this status. Turn off the WWAN and then reconnect the WWAN to fix the problem. Question: CCM sometimes fails to respond after resuming from Suspend mode. What could be the problem? Answer: If the “General” tab under the Edit Profile screen for GSM is left open, this can often keep CCM from reopening upon resuming from suspend mode. Make certain the “Edit Profile” screen has been closed after making any changes. A reboot should correct the problem. Question: When I try to connect through Cingular GPRS network, the Connect/Disconnect button is greyed out, and there is no connection available. Answer: Click on the “Connect Using “tab in CCM, and check one of the connection types from the drop down menu. Close out of CCM and reboot. Question: I noticed an option to create a CSD Accelerated/Non-Accelerated network profile. What is this? Answer: CSD is Circuit Data Network. This is an older technology with lower throughput which has been phased out. We recommend that EDGE/GPRS Acelerated/NonAcelerated profile options be used instead. ❑ SMS Question: What does “Load” do and why does it not prompt for options or input? Answer: The SMS help file indicates this is useful in case of accidental deletion of messages. The “Load” feature would be a way to recover the 28 Answers to Frequently Asked Questions deleted messages, however, this option provides no notification that the task completed successfully. Question: What does “Save” do and why does it not prompt for options or input? Answer: The help file indicates this keeps the current state of all folders, except the inbox. However, no notification is sent indicating the “Save” completed. Question: I copied a message to the “Outbox”. Why does it not prompt to enter the recipient? Answer: Although you can move or copy a message from one folder to another, including the “Outbox”, the message must have a recipient before the message can be sent. If the message is copied and/or moved to the “Outbox”, the message still will not have a recipient, thus leaving the message unable to be sent. This would be considered the same as a the “Forward message” feature. The message would remain in the “Outbox” indefinitely until a destination or destinations are provided. For working around this, we recommend double-clicking on the message, enter a recipient, and then click “Send”. Question: I created an SMS message, but am not connected to GRPS. How is it possible that the message can be sent? Answer: Sending SMS does not need a GPRS data connection. As long as it detects and attaches to the Cingular network, it will able to send SMS. Question: What is, and what does the function button “Update Address Book with Phone Book Contents” do? Answer: When the SIM is installed, it contains a built-in phone book, which when using this feature, allows the contents of the phone book to be incorporated into the address book. Question: Why I am not alerted of transferring the contents of phone book to the address book? Answer: This is a feature that is still under development. A request for further study to be conducted with this option has been applied. Question: When I select a message from a folder, and then scroll right, the all previously existing messages appear to be gone if I scroll back to the 29 VAIO® Computer Wireless Information original folder position. Answer: Click out of the folder, and then back in to refresh the screen. Question: I clicked on the Cingular Connection Manager minimize button and noticed that the CCM icon was not in the taskbar. Where is the minimize icon and how do I bring forth the application to the desktop? Answer: The CCM minimizes into the Task-tray, which is represented by the “Cingular” trademark cross icon and not into the “Taskbar” (see the Cingular logo illustration below). Depending on the strength of the GPRS signal, the trademark will reflect this with a degree of graduations. In other words, if the signal strength synchronizes to 3 bars (see the Task-tray illustration below), the Cingular trademark cross will show approximately half of trademark jackman in the task tray. If the signal strength is one bar, the trademark jackman will appear to show a bottom portion of the trademark jackman. If the signal strength is at five bars, the entire Cingular trademark jackman will be fully indicated. To bring forth the CCM to the desktop, click the Cingular trademark icon in the task-tray or right-click the Cingular trademark cross and select “Show”. Cingular logo trademark jackman Minimized Cingular logo trademark jackman ❑ GPRS Network Question: Why do I see a network connection speed rate of 214.4 Kbs, but when I try to access a website that requires a minimum of 128 Kbs, I am told that I do not have the required minimum rate. Answer: The network speed indicator provides the capacity of the wireless device is 214.4 Kbs but the actual speed depends on network throughput. To work around this, try to change the network settings to optimize the 30 Answers to Frequently Asked Questions GPRS/EDGE value. This is done by accessing CCM --> Tools --> Settings… --> Advanced Networking, and then selecting “Optimized GPRS/EDGE value” option form the RWIN variables window. Question: I am experiencing dropped connections, slowness, and other difficulties while attempting to stream video over the Cingular GPRS connection. What could be the problem? Answer: Bandwidth over the Cingular GPRS network is somewhat restricted as compared to wired or 802.11x wireless connection types. Due to the demanding nature of streaming audio/video, it is not recommended that GPRS be used for either streaming video, or very large data downloads. Question: I am experiencing difficulty reconnecting to my web browser when switching from the Cingular GPRS network to a WLAN connection. What could be the problem? Answer: The network behind the WLAN’s Access Point may be set up to use a proxy server. If this is the case, proxy settings entered for Internet Explorer over WLAN may prevent IE from connecting over a GPRS link. To allow web browsing from either connection type: Correctly configure IE proxy settings for use over the WLAN connection. Then, open the Cingular Connection Manager and rightclick the “GSM” tab. Select “profiles” and then click on the “Edit” button. Under the “General” tab, make certain that the “Disable IE’s manual proxy settings on connect” checkbox has been enabled. Close the “Edit” screen and then close and reopen Internet Explorer. Remember to close and reopen IE each time you switch connection types in order to refresh proxy settings within Internet Explorer. If you are still having trouble, contact your network administrator to assist in obtaining the proxy settings. Question: I am seeing a message in Windows taskbar stating; “GPRS a Network Cable is Unplugged”. What does this mean? Answer: Typically, this message appears if your VAIO PC is connected to the Cingular GPRS network and is allowed to go into hibernation. Upon resuming, Cingular has terminated the connection. However, Windows information has not yet been updated to recognize this change and is unaware that your GPRS connection does not require a cable. You may 31 VAIO® Computer Wireless Information either re-connect to Cingular, or simply cancel out of the message. Question: Downloads sometimes appear to be slow when connecting to the Internet via CCM. What type of download speeds should I expect? Answer: Since CCM operates over a cellular network and is subject to the same issues/conditions as cellular connections, bandwidth may vary greatly. Common download speeds ranging from 18~64Kbps are possible with 30~36Kbps rates as typical. However, these are only estimates and your actual experience will likely vary depending upon a number of environmental factors. Question: What is meant by “RWIN” from the CCM Tools settings advanced networking section? Answer: The TCP Receive Window size is the amount of ‘receive’ data (in bytes) that can be buffered at one time on a connection. RWIN (TCP Receive Window) can be changed using the method of setting up the variables to optimize TCP. We recommend that this setting not be changed unless you are an expert or you have explicit instructions from your network administrator. ✍ Changing the settings for this value also has an effect when using WLAN device or any device that depends on TCP connection. ❑ Sonic Stage/Music Store Question: I am unable to stream audio from some web sites such as Winamp©, Shoutcast©, etc. using Sonic Stage? Why is this the case? Answer: Many of these web sites use proprietary players and use encoding formats that are not supported by other players. You can download one of these players if you wish, or try streaming from Sony Connect™ Music Store using Sonic Stage. Question: Sonic stage appears to lock up indefinitely (displays a spinning ‘LOADING’ logo) when attempting selecting “Radio Connect” (streaming) from Sony Connect™ site. Answer: This is related to the issue of streaming audio over low bandwidth connections as referenced above under “GPRS Networking”. Connecting to Music Store over a wired or broadband connection will usually resolve this issue. 32 Answers to Frequently Asked Questions ❑ Bluetooth® technology Question: Why do I not see the Bluetooth device that is connected to the computer from the BT Paired Device status box of the SmartWi Connection Utility? Answer: It is most likely no Bluetooth devices have been configured for the system. Bluetooth devices are not configured automatically. To install or configure Bluetooth devices, you will need assistance in setting up the Bluetooth device on the computer. Follow steps from the help section “Installing the Bluetooth device”. We recommend obtaining the latest Bluetooth drivers. Question: I can not connect to my Bluetooth keyboard (or other device). What could be the problem? Answer: You will need to make certain that you are using the most current drivers available for your Bluetooth device. Try reinstalling under the updated driver per the manufacturers instructions. ❑ Uninstall, Reinstall and Repair Question: How do I uninstall the SmartWi application and all its associated modules?
