I went through the wizard to add a MD device. After selecting manufacturer, device catagory and choose "generic PC as MD", I clicked the close button. Then, I was sent back to the add device page. Nothing happens. I do a quick reload router and even reboot the CORE. Nothing happens. Can someone offer a help? Thank you.
Before closing you should press the button 'View Template' or similar (near dropdown list with devices). After that MD will be added and window will be closed.
Moreover, in the .40 MD is PnP. So, you shouldn't do this manual installation. But in my case, I couldn't setup MD as PnP.
