Windows Mobile Journal: Adding Wi-Fi to the Treo 750
The first thing you need to do is obtain your Treo 750 (United States) or Treo 750v (Europe). Then you need to purchase the Spectec card. I ordered mine from the TreoCentral online store. Once it arrives, it is time to set it up. One thing that wasn't clear from reading articles and reviews of the Spectec WLAN card I found online was whether or not the card works with Windows Mobile 6.0. All the reviews and spec sheets I saw talked about Windows Mobile 5.0, the version of Windows Mobile that originally shipped on the Treo 750 series. I can tell you that the Spectec card does work with Windows Mobile 6.0 - you just need to download the Windows Mobile 6 driver first.
Note: I'm not going to repeat the process for setting up the Wi-Fi card under Windows Mobile 5.0. There are already directions for doing that online.
Download the Windows Mobile 6 WLAN card driver from the Spectec website. Then copy the driver, wlan11b_wm60.CAB, down to your Treo 750. Once you have copied the file to the Treo, use Windows Explorer to browse to the file and execute it. The driver will install on your Treo. You may need to soft reset your device.
Now that the driver it is almost time to turn it on. If you are using an AT&T Treo 750, before you can establish a data connection to anything other than AT&T's data network, you will need to disable the forced AT&T proxy server setting. In the Programs folder (Start > Programs), launch the Proxy Manager application and uncheck the Force AT&T Proxy checkbox. When you do, you will receive a notice that the proxy server has been disabled. Press the OK button to clear the warning.
Now, turn off the cell phone radio, insert the card, and then open the Wireless Manager application (Start > Settings > Connections > Wireless Manager). You will now see a Wi-Fi section.
Press the menu button to access the Wi-Fi Settings screen. From there you can setup the connection properties for the Wi-Fi hot spots that are in range.
At this point, you can launch an Internet application like Pocket Internet Explorer or Pocket Outlook and surf the web or check you email.
