phone app support

I have a brand new Profilux 4 Mega Set, literally just unboxed it last night and cannot get the wifi hotspot to show at all. At first there was a yellow wifi light and I could get my phone to connect to the hotspot but it could never connect to the app. Now there is no wifi lights at all, yellow...

I have a Red Sea 659 S Max system. I recently purchased a second doser 4 that I am trying to get to connect. Has anyone successfully connected 2 doser 4's? I get a IP address, firmware update, it prompts for schedule (skip), appears to connect and grays out. Any assistance is appreciated...
