EC200A-EU windows RNDIS mode

I test EC200AEUAB module in Windows . I can connect with dialup PPP to internet.
But I cannot connect to internet from RNDIS adapter(AT+QCFG=“usbnet”,3). It has dhcp client IPs but no Internet. How can I set to connet RNDIS to internet?

OK I found out the missing command. It must be called “at+qnetdevctl=1,1,1” command o establish a data connection for RNDIS or ECM interface with EC200A-EU.

Yes. Just as what you have done, the EC200A need to set up data call with AT.
