I have been a windows mobile device user for some time. This is a guide for connecting Windows Mobile devices to Wireless (wifi) networks. For anyone that might have difficulty finding out what the mac address on their PPC I would recommend using vxipconfig it is a great free application that is similar to ipconfig for Windows.
If there is some type of connection manager find it and enable the wireless card on my device a T-Mobile mda there is a button dedicated to starting the connection manager, from there wireless can be toggled on and off
Tap Start > Settings
Select the “Connections” tab and then tap “Network Cards”
Then tap “Add New…”
For “Network name” enter in “nomad”
Then select the “Network Key” tab. For “Authentication” select “Open” and for “Data Encryption” select “Disabled”.
After you have made these changes just tap “OK”
You should be taken back to “Configure Wireless Networks”. Tap and hold “nomad” and select “Connect”. This might take a few seconds, after it is done just tap “OK”. If all goes well you should be on the network.
To make sure you are on the wireless network you can check it by doing the following. Tap Start > Settings Select the “Connections” tab and then tap “Wireless LAN”
You should see a screen similar to the following
