Prefer IPv4 over IPv6 for WLAN Adapters

Copper Contributor

Hello

 

In our company I have configured "Prefer IPv4 over IPv6" for all devices (GPO).

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters\DisabledComponents.
Value: 0x20

 

Apparently this setting has no effect on the WLAN adapter.
How can I set this for the WLAN adapter?

Hi @Int3g3rWork,

One possibility is that the GPO is not linked to the OU or domain that contains the WLAN adapters. To check this, open the Group Policy Management Console (gpmc.msc) and navigate to the GPO that you want to apply. In the Security Filtering tab, make sure that the OU or domain that contains the WLAN adapters is listed.

Another possibility is that the GPO is missing the required settings. To check this, open the GPO in the Group Policy Editor (gpedit.msc) and navigate to the Computer Configuration > Windows Settings > Network Settings > Wireless Network (IEEE 802.11) Policies node. Make sure that the Prefer IPv4 over IPv6 setting is enabled.

If the GPO is linked to the correct OU or domain and the required settings are present, but the GPO is still not working for WLAN adapters, you can try the following troubleshooting steps:

  1. Make sure that the WLAN adapters are configured to receive Group Policy settings. To do this, open the Network Connections window and right-click on the WLAN adapter. Select Properties > Security > Advanced > Change settings. In the Group Policy tab, make sure that the Turn off Group Policy checkbox is not selected.
  2. Flush the DNS cache on the WLAN adapters. To do this, open a command prompt window and run the following command:

 

ipconfig /flushdns​

 

  1. Restart the WLAN adapters. To do this, right-click on the WLAN adapter in the Network Connections window and select Disable. Then, right-click on the adapter again and select Enable.
