Check all your current settings about the enabled network adapters. This means, that when you establish some connection like ActiveSync/WiFi/3G/GPRS/CSD and run NetInfoBox (or by hitting Refresh button if the tool is already is up), you will be able to see everything about this connection like:

– Status and type of selected adapter
– MAC address
– IP address
– Network mask
– Primary DNS
– Primary WINS
– Speed limit
– ID of the adapter
