All we can do as you said is really wait. But what odd is, multiple versions had been released since last year but these persistent issues are still NOT resolved. I hope that they can restore the manual input of static IP address/MAC address like the settings of previous WiFi routers, instead of needed to connect these gadgets to be registered.
I hope that they could review again its functional framework design, comparing their old WiFi router settings which mostly are still usable. I've invested many D-Link products and know what they achieved before so I believe that they can restore these indispensable setting and make it WORK flawlessly. The competition offers many but really helpful setting which D-Link has to offer also.
