Well that was a chore, got my noo-psyche light today. It does not play well with newer routers even if you can separate the bands... Even tried the whole hotspot on the phone trick, worked for jebao but not this.
Had to drag out an old wireless G router, set up an identical network, connect to the light, then it would connect to my router, at which point adjust the IP address in the app and bingo. I have full wifi connection to the light.
Unlike the jebao stuff, functionality is exactly the same as in AP, you still have to be connected to the same network and you can't connect to it outside of that network. So time wasted, AP mode works just as well.
Just need to mount it and take par readings.
Now I need more SBB corals for my Fluval.
