Symptoms

On a Windows Embedded Compact 7-based device, you may experience the following issues.

Issue1

Consider the following scenario:

  • You have a Windows Embedded Compact 7-based device that has a Wi-Fi adapter installed.

  • You configure a static IP address for the Wi-Fi adapter and connect to a wireless access point.

  • You confirm the IP address¬†and disconnect from the wireless access point. To disconnect, you delete the wireless local area network (WLAN) profile from the NETUI dialog box.

  • You reconnect to the wireless access point and confirm the IP address for the Wi-Fi adapter.


In this scenario, you may notice that an automatic IP address is assigned to the Wi-Fi adapter even though a static IP address is configured.

Issue 2

Consider the following scenario:

  • You have a Windows Embedded Compact 7-based device that has a Wi-Fi adapter installed.

  • You enable Dynamic Host Configuration Protocol (DHCP) configurations for the Wi-Fi adapter and connect to a wireless access point.

  • You confirm the IP address of the Wi-Fi adapter and disconnect from the wireless access point. To disconnect, you delete the wireless local area network (WLAN) profile from the NETUI dialog box.

  • You reconnect to the wireless access point and confirm the IP address again for the Wi-Fi adapter.


In this scenario, you may notice that the assigned IP address is changed every time that the connection is established even though the lease period is not expired.

Cause

These issues may occur because the DHCP module for Windows Embedded Compact 7 does not handle IP address assignments correctly.
