I tried to solve myself and I can say that one of the images is Newnigma2 4.0.18 (not the lean) + usb stick wifi D-Link 122 (Ralink 2800). I put and usb stick with Flashexpander (mounts as media / usb) And everything works perfectly - Dm 500HD with Ridax x 2usb kit. I hope to be helpful for others too.
