On web interface of NC200, go to Advanced---Wireless Connection. Under network list, press manually button and you can input wireless name and password manually.

There are no advance options during the setup and I can't find your described advanced menu

Can you exit the wizard? Or after finish wizard, can you see the menu on the left side? I'm checking its emulator here.

Wizard exited but only after I was forced to choose Wired connections for future use.

And now I tried to use the TP-Link Camera Control but was then shown to log in to my camera, which didn't accept any of my passwords at all, nor was I able to change the user name.
Deleting the camera and re-adding also came back to the same.

I can view the screen from the Cloud Admin link on my browser, but I am still unable to convert it to a wireless setting.

I just realized that we are talking about different things. Can you log in web interface of NC200?
