FIX: A Windows Embedded Compact 7-based device cannot obtain an IP address from the DHCP server

Symptoms

Consider the following scenario:

  • You have a Windows Embedded Compact 7-based device.

  • There is a wireless router with Dynamic Host Configuration Protocol (DHCP) enabled on the network.

  • You connect the device to the network by using a wireless router.


In this scenario, you may notice that the device cannot obtain an IP address.

Cause

This issue occurs because the Windows Embedded Compact 7-based device uses the BROADCAST packet type to send DHCP discover messages. However, the wireless router may not support the packet type.
