Troubleshooting a Bluetooth Network Connection

If you can’t get any connectivity at all using Bluetooth, try the following remedy: 1. Go to the computer that’s having trouble connecting to the PAN.

2. Open Network and Sharing Center. Tap the Windows key, type net, and click Network and Sharing Center. Or click the Start button and choose Control Panel -> Network and Internet -> Network and Sharing Center.

3. Scroll down to the Bluetooth Network Connection group. If you’re unable to locate the Bluetooth Network Connection group, you’ll need to follow the steps outlined earlier including entering a passkey from the other system in the PAN. By the time you complete the wizards on both screens, you should have a connection. The Network and Sharing Center folders on each PC should have similar Bluetooth network entries.

Sharing an Internet connection

If you’re unable to get Internet connectivity from the laptop computer, go to the computer that’s connected to the modem or router. Open Network and Sharing Center and choose Manage network connections from the left side of the screen. Right-click that Internet connection icon and choose Properties. Also, check the settings for the Windows Firewall:

1. Tap the Windows key, type fire, and click Windows Firewall. Or click the Start button and choose Control Panel -> Security -> Windows Firewall.

2. Click the Change settings link and then the Advanced tab.

3. Make sure that Bluetooth Network Connection is checked to enable that type of network connection.

With these settings you should now be able to connect to the Internet from the other computers in the PAN

If a built-in radio driver doesn’t work with your device, install the drivers that came with the device per the device manufacturer’s instructions. Configuring Your Bluetooth Adapter

If you plan to share a single Internet account among several computers or Bluetooth devices, you should install your first Bluetooth USB adapter in the computer that connects directly to the modem or router. That will give other Bluetooth devices that you add later easy access to the Internet through that computer’s Internet connection. The Bluetooth Devices dialog box will be your central point for installing Bluetooth. To open that dialog box, double-click the Bluetooth Devices Notification area icon, or open the icon in Control Panel. Initially, the Devices tab in the dialog box will be empty. But as you install devices and join devices to a Bluetooth PAN, you’ll see the names of those devices listed on that tab. The Options tab in the Bluetooth Devices dialog box, provides general options for controlling discovery and the ability to install Bluetooth devices. If you don’t see a Bluetooth Devices icon in your Notification area, make sure to choose the Show the Bluetooth icon in the notification area checkbox.

Adding Bluetooth-Enabled Devices

There are many different types of Bluetooth devices on the market. Most have some means of making the device discoverable (visible) to other devices. Whether or not you have to make your PC discoverable to install a device depends on the type of installation you’re about to perform. As always, you need to read the documentation that came with your device for specifics. But if you do need to make your computer discoverable, it’s simply a matter of choosing the “Turn discovery on” option. On the shortcut menu for the Bluetooth Devices notification icon, the Add a Bluetooth Device option opens the Add Bluetooth Device Wizard, which takes you step by step through the process of adding a device. The sections that follow discuss general techniques for adding Bluetooth devices, many of which will involve the Add Bluetooth Device Wizard.

Installing a Bluetooth printer

To install a Bluetooth printer, follow the printer manufacturer’s instructions for turning on the printer and enabling its ability to connect to a computer. Then, on your PC:

1. Click the Start button and choose Printers. Or, click Start and choose Control Panel. If Control Panel opens in Category view, click Hardware and Sound. Select the Printers link to continue.

2. In the Explorer bar, click on Add a printer.

3. On the first wizard page, select the Add a network, wireless or Bluetooth printer option.

4. Click Next, and Windows will start searching for your Bluetooth-compatible printer. If Windows is unable to locate the printer, it probably means that either the printer is not powered up or there is a problem with the Bluetooth device connected to your computer. Try clicking the link The printer that I want isn’t listed and then select Add a Bluetooth printer.

5. After your printer has been found, follow the remaining wizard instructions until you can click the Finish button to complete the job. When it is installed, you should be able to print from any Bluetooth device according to the instructions that came with that device. To print a document from your computer, follow the usual procedure (choose File -> Print from the program’s menu bar), and choose the Bluetooth printer from the Printer Name options in the Print dialog box.

Install a Bluetooth keyboard or mouse

To install a Bluetooth keyboard or mouse, you must first connect the device by cable, or use a cable-connected mouse or keyboard to provide the initial connectivity. Also, you must know how to make your mouse or keyboard discoverable (visible). If you’re not sure how to get started, refer to the instructions that came with the mouse or keyboard. If you’re installing a keyboard, check its documentation to see if the keyboard supports the use of a passkey. And if so, find out if it already has a pre-assigned passkey, or if you can use a passkey of your own choosing. Then, to perform the installation, follow these steps:

1. Right-click the Bluetooth Device Notification area icon and choose Add a Bluetooth Device. Or open the Bluetooth Devices applet from Control Panel or its notification icon, and click the Add button at the bottom of the Devices tab.

2. Choose My device is set up and ready to be found and click Next.

3. Click the discovered device’s name, and then click Next.

4. If you’re adding a keyboard, do one of the following as appropriate for your device:

- To have Windows create a safe, random passkey, click Choose a passkey for me.

- If your device has a predefined passkey, choose Use the passkey found in the documentation, and then type the passkey.

- If you want to create your own custom passkey, click Let me choose my own passkey, and then type a passkey.

- If the device doesn’t support the use of passkeys, choose Don’t use a passkey.

5. Click Next and follow the remaining instructions presented by the wizard.

Install a Bluetooth mobile phone

Some Bluetooth mobile phones can connect to a computer to synchronize phone articles and transfer files. Some (but not all) mobile phones can also act as modems to connect to the Internet. Make sure that you read the documentation that came with the phone so that you understand how to make the phone discoverable, how to name the phone (if necessary), basic information on setting up a passkey, and whether or not you can use the phone as a modem. If your mobile phone can act as a modem, you’ll need a dial-up Internet account to connect to the Internet. Most likely this will be a mobile service provider. You’ll need to know your user name, password, carrier code or phone number, and other basic account information prior to setting up your Internet account. Only your Internet service provider (or mobile service provider) can give you that information. The exact procedure for installing a Bluetooth phone will vary from one phone to the next. But to get started, make sure that discovery and the ability to add new devices is enabled on your PC. Then, follow these steps:

1. Right-click the Bluetooth Device Notification area icon and choose Add a Bluetooth Device. Or, open the Bluetooth Devices dialog box from Control Panel or its notification icon, and click the Add button at the bottom of the Devices tab.

2. Follow the instructions presented by the wizard, and as specified by the mobile phone manufacturer.

If the phone you installed in the preceding steps can act as a modem, you can then proceed with the following steps to set up a Bluetooth connection to the Internet:

1. Open the Network and Sharing Center folder by clicking the Start button and choose Control Panel. If Control Panel opens in Category view, click Network and Internet. Open the Network and Sharing Center icon.

2. Click Set up a connection or network from the left column.

3. Select the option Set up a dial-up connection and then click Next.

4. If your computer sees the mobile phone connected via Bluetooth, it will prompt you for the information. When the information is filled out, click the Connect button to continue.

5. When you have successfully dialed your ISP, either click the link Browse the Internet now or click the Close button.

When your connection is configured, you should be able to get online by opening Network and Sharing Center from the Control Panel. Click Connect to a network link on the left side of the window.

Connect a Bluetooth Blackberry

To connect a Bluetooth Blackberry device to your computer, make sure that you first make the Blackberry discoverable (visible) and (if necessary) give the Blackberry a name. Complete the following steps:

1. Right-click the Bluetooth Device Notification area icon and choose Add a Bluetooth Device. Or open the Bluetooth Devices dialog box from the Control Panel or its notification icon and click the Add button at the bottom of the Devices tab.

2. Make sure that the Blackberry option for Discoverable is set to Yes under the Bluetooth settings.

3. From within Vista, check the box My Device is set up and ready to be found and then click the Next button.

4. Follow the remaining steps in the wizard including setting the passkey so that your computer and Blackberry can communicate. After the wizard completes, Windows may prompt for additional software to be installed. You can tell Windows to look locally and on the Internet or to load the software for the device from a CD provided by the vendor.

Connect a Bluetooth Windows Mobile device

To connect a Bluetooth Windows Mobile device to your computer, make sure that you know the handheld PC well enough to make it discoverable (visible), and (if necessary) to give the handheld a name. Complete the necessary steps, and then follow these steps on your PC:

1. Right-click the Bluetooth Device Notification area icon, and choose Add a Bluetooth Device. Or, open the Bluetooth Devices dialog box from Control Panel or its notification icon, and click the Add button at the bottom of the Devices tab.

2. Follow the instructions in the Add Bluetooth Device Wizard to install your Pocket PC. Enter the passphrase when prompted, and then click Finish when the wizard completes. After you’ve completed the wizard, the Windows Mobile Device Center application should start.

Prior to Windows Vista, Microsoft provided the ActiveSync software that you installed on your computer to communicate and synch your handheld device. With Windows Vista, however, the functionality has been incorporated into the operating system in the Windows Mobile Device Center application.

From this point on, the Windows Mobile device is paired with your computer. You should be able to follow the instructions that came with your Windows Mobile device to synchronize that device with your PC.

Install a Bluetooth Palm PC

To connect a Bluetooth Palm PC to your computer, make sure that you know the handheld PC well enough to make it discoverable (visible) and (if necessary) to give the handheld a name. Complete the necessary steps, and then follow these steps on your PC:

1. Right-click the Bluetooth Device Notification area icon and choose Add a Bluetooth Device. Or open the Bluetooth Devices dialog box from Control Panel or its notification icon and click the Add button at the bottom of the Devices tab.

2. Follow the instructions presented by the Add Bluetooth Device Wizard.

3. If you see COM (serial) port numbers on the Finish page of the wizard, write them down, because you’ll need those numbers later.

If the Finish page in the wizard doesn’t list COM ports (or serial ports), don’t worry about it. That just means your Palm PC doesn’t use, or require, a COM port.

Now you can install, on your PC, the HotSync software, and any other software that came with your Palm PC (unless, of course, you’ve already installed that software). But whether or not you’ve already installed the software, at some point you’ll be asked to provide COM port, or serial port, numbers. Be sure to use the numbers provided on the Finish page of the Add Bluetooth Device Wizard as described in step 3. To use your synchronization software, follow the instructions that came with your Palm PC.

Joining a Bluetooth personal area network

A Bluetooth personal area network (PAN) is a short-range wireless network used to connect devices together wirelessly. It’s commonly used to connect a laptop to a desktop PC, though it can be used to connect other types of Bluetooth devices. As a rule, there’s not much to joining Bluetooth devices to a Bluetooth network. Most of the action takes place automatically behind the scenes. To understand the basic procedure, let’s assume you already have a desktop computer with a functional Internet connection. You’ve already installed a Bluetooth USB adapter on that computer, so it’s now a Bluetooth device. On that desktop computer, you can open the Bluetooth Settings dialog box, click the Options tab, and make sure that the Turn discovery on and Allow Bluetooth devices to connect to this computer options are selected. On a laptop computer, plug in a second Bluetooth USB adapter. You want to connect the laptop to the desktop in a personal area network. To do so, starting from the laptop computer, follow these steps:

1. Right-click the Bluetooth Devices Notification area icon and choose Join a Personal Area Network. A list of Bluetooth devices should appear. If at least one device does not appear, click the Add button and follow the steps to locate a Bluetooth-enabled computer.

2. Click the name of the computer to which you want to connect, and click the Connect or Next button.

3. Choose a passkey method from the next wizard screen (the Choose a passkey for me option is sufficient), and then click Next.

4. You’ll be given a passkey as in the upper-left corner. On the other computer, you’ll be asked to type in that same passkey, as in the lower-right corner. Type in the passkey exactly as shown in the first computer and click Next.

5. Follow any remaining instructions in the wizards on both computers until you get to the Finish page and then click the Finish button in each wizard.

Once the connection is established, you should have Internet access on both computers. You can share printers and folders, and move and copy files between computers using the techniques described in Articles 29 and 35.

Note, however, that if you made the Bluetooth connection to only one computer in an existing LAN, you’ll have access only to the shared resources on the Bluetooth-enabled computer, not all the computers in the LAN.

Troubleshooting a Bluetooth Network Connection

If you can’t get any connectivity at all using Bluetooth, try the following remedy: 1. Go to the computer that’s having trouble connecting to the PAN.

2. Open Network and Sharing Center. Tap the Windows key, type net, and click Network and Sharing Center. Or click the Start button and choose Control Panel -> Network and Internet -> Network and Sharing Center.

3. Scroll down to the Bluetooth Network Connection group. If you’re unable to locate the Bluetooth Network Connection group, you’ll need to follow the steps outlined earlier including entering a passkey from the other system in the PAN. By the time you complete the wizards on both screens, you should have a connection. The Network and Sharing Center folders on each PC should have similar Bluetooth network entries.

Sharing an Internet connection

If you’re unable to get Internet connectivity from the laptop computer, go to the computer that’s connected to the modem or router. Open Network and Sharing Center and choose Manage network connections from the left side of the screen. Right-click that Internet connection icon and choose Properties. Also, check the settings for the Windows Firewall:

1. Tap the Windows key, type fire, and click Windows Firewall. Or click the Start button and choose Control Panel -> Security -> Windows Firewall.

2. Click the Change settings link and then the Advanced tab.

3. Make sure that Bluetooth Network Connection is checked to enable that type of network connection.

With these settings you should now be able to connect to the Internet from the other computers in the PAN.

Transferring files between Bluetooth devices

When you connect two computers in a Bluetooth network, you can move and copy multiple files between computers using the techniques described under “Transferring Files between Computers” in Article 54. You can also use the Send a File and Receive a File options on the Bluetooth Devices shortcut menu as an alternative. However, you can’t move files that way, and you can only copy one file at a time. So, this method usually is best for transferring files to a noncomputer Bluetooth device. But still, if you want to transfer one file between computers using this method, here are the steps:

1. On the computer to which you plan to send a file, right-click the Bluetooth Devices icon in the Notification area and choose Receive a File. The Bluetooth File Transfer Wizard opens and waits for you to send a file from the other computer.

2. On the computer that contains the file you want to copy, right-click the Bluetooth Devices notification icon and choose Send a File.

3. In the wizard that opens, click the Browse button, choose the computer (or device) to which you want to send the file, and then click OK.

4. If the two devices are already paired using a passkey, the passkey options will be disabled, and you can ignore those options. Just click Next.

5. Click the Browse button on the next wizard page, and navigate to the folder that contains the file on the local system that you want to send. Then, click the icon of the file you want to send, and click the Open button. Then click Next.

6. On the receiving computer, the wizard asks what you want to name the file and where you want to put it. Type a filename for the file you’re about to receive, and use the Browse button to choose the folder in which you want to put the file. Then click Next.

7. When the transfer is complete, click the Finish button in the last wizard page on both computers.

Remember, there are many different Bluetooth devices on the market. If none of the techniques described here help you make the connection between two computers in a personal area network, be sure to refer to the instructions that came with your Bluetooth device
