Hi, welcome to the community.

The CWMP function is typically used by ISPs for centralized management of Deco units. For personal Deco nodes, we recommend managing them through the Deco app.

The CWMP Settings page typically requires you to fill in ACS server information. If the connection fails, it may be because the ACS server is not working or the configuration information is incorrect. We suggest checking the ACS server status and related information. This connection is generally unrelated to VLAN.

Best regards
