And also. Im using Deco XE200. So this is a different router then the first guy. Seems like it has something to do with the app at this point.. Pretty sure i have tried everything you can think of.

@Barty i got the same issue right now. Whenever i try to do anything in the app the main Deco goes to red light and internet is gone. If i don't do anything in the app my internet works fine and no...
