D7000v2 doesnt let smart plugs be configured

[Nohndie]

I have switch to the d7000 and since then my smart plugs and bulbs have started flickering on and off. I went to add another 2 plugs and the app wouldn't see them to configure so I switch to my ISP router and it seen them first time. What could be stopping these from working?
Aoycocr smart plugs is what I'm using

what ISP router do you have? Is a modem/router combo device? What mode is it running in? 

How do you have the D7000 setup? Is it setup running as a dsl modem/router combo device? is it running strictly as a router? Is it running in access point mode?

When you setup your smart devices, did you have your phone connected to the 2.4ghz band or the 5ghz? Lazy coding usually makes it so your phone has to be on the same wireless band the smart devices will be one?
