Are you working with the Integration or Development kit?
For starters, with either kit, you will need an unsecured Access Point (no WEP or WPA encryption enabled).
Once the Wi-EM(ME) has obtained network association you should be able to discover the device using one of the following two utilities:
1. The Digi Connect Programmer (dgdcprog.exe) is for Integration kit units.
2. The NET+OS Programmer (netosprog.exe) is meant for Development kit units running the default firmware.
As egawtry has mentioned below, when working with the development kit the IP address can be forcefully assigned via the appconf.h file. This method, however, is only intended for use during development, as it requires that a) the device's NVRAM be blank or corrupted or b) that the NVRAM not be used (APP_USE_NVRAM set to FALSE), which would be problematic during the products use in the field.
