Disabling IPv6 on Datalogic Devices Running WEC7

🧾 Description 

This article outlines two methods for disabling IPv6 on Datalogic devices running Windows Embedded Compact 7 (WEC7). Disabling IPv6 may be necessary for compatibility with certain networks or applications. The first method uses a command in the autostart.ini file, while the second involves modifying the system registry.
 

🛠️ Resolution Steps

Method 1: Using autostart.ini
Steps:

1. Create or edit the autostart.ini file in the FlashDisk directory.
2. Add the following command to unbind the IPv6 protocol from the wireless adapter:  INIcmd.exe /C ndisconfig adapter unbind TIWLNAPI1 tcpip6Show more lines
3. Save the file and reboot the device.

Note: This method may not persist after a cold boot. If it fails, proceed with the registry method below.

Method 2: Using Registry Keys
Steps:

1. Open a registry editor on the device.
2. Navigate to the following path:  [HKEY_LOCAL_MACHINE\Comm\Tcpip6\Parms]
3. Add or modify the following keys: INIreg isn’t fully supported. Syntax highlighting is based on INI."EnableDHCPv6"=dword:00000000"DisabledComponents"=dword:000000ffShow more lines
4. Save the changes and reboot the device.

Note: Always back up the registry before making changes.

Important Notes

• Disabling IPv6 may affect connectivity with networks or services that rely on IPv6.
• Registry changes are persistent across reboots and are recommended for long-term configuration.
