b. In the Bluetooth Devices window, click Add.

c. The Add Bluetooth Device Wizard opens. Select the My device is set up and ready to be found check box, then click Next.

d. The wizard then detects your phone and displays its name in the dialog box. Select the phone name, then click Next.

e. Select Let me choose my own passkey, then enter a passkey (1 up to 16 digits) that will serve as an identification number for establishing a secure connection between your phone and the computer. Click Next.

f. A confirmation message appears on your phone. Click Yes to accept the connection, enter the same passcode, then click Next.

g. On the computer, click Finish to exit the wizard.

h. On your phone’s Partnership Settings screen, you can change the display name for the computer, then click Finish.

3. Now, open the Internet Sharing program on your phone. Select Start

> Accessories > Internet Sharing.

4. Select Bluetooth PAN as the PC Connection.

5. From the Network Connection list, select the name of the connection that your phone uses to connect to the Internet.

6. Select Connect.

7. On your computer, set up a Bluetooth Personal Area Network (PAN) with your phone:

a. Click Start > Control Panel > Network Connections.

b. Under Personal Area Network, click the Bluetooth Network Connection icon.

c. Under Network Tasks, click View Bluetooth network devices.

d. In the Bluetooth Personal Area Network Devices dialog box, select your phone, then click Connect.

8. On the Internet Sharing screen on your phone, check if a connected status is displayed, which indicates that your computer has been successfully connected to the Internet using your phone as a Bluetooth modem

    Nice summary–many thanks!

    Is there any way to run BOTH ActiveSync and ICS simultaneously?  I need to have both running in order to update various medical software (e.g. MercK Medicus).  I used to be able to do it running XPSP2 on my laptop and WM5 on my PDA with Bluetooth DUN and ActiveSync–but since I upgraded to WM6 I cannot get ActiveSync to run while ICS is running.

    Hello does anyone know how to share a modem connection from the dash to a PDA(Advantage 7550)on a Bluetooth pairing.  

  7. Clymmer says:

    Thanks for the clear instructions!   These worked like charm.

    Albeit a dismally-slow-24Kbps-84Kbps-internet-connection charm, but a charm nonetheless. 😉  In a pinch, this’ll do!

    Does anyone know how to internet share between 2 Dash’s (mine and my wife’s)? I have a data plan – her’s does not. I called T-Mobile and they instructed me to go though what appears is the same way to hook up to a PC via Bluetooth – but can’t seem to get her’s to work.

  14. kevin says:

    i was wondering what if it says "check your usb cable" because i still cant connect to the internet for some reason through the computer

    worked great! Much easier than the other articles I read while searching on Google for "dash usb modem." Thanks!

  16. Lauren says:

    I can get the connection working but can’t send email through Outlook on my computer when using the Dash as a modem (though I can receive them).  Any thoughts?
