Wifi disconnecting and not auto reconnecting

My WiFi over past few weeks has twice cut out according to SS.

First time it happened none of the cameras would work (understandable) so I was confused as I like many would get wifi lost wifi restored random appearing during nights.. but at this point it was wifi lost but not restored which I thought was unusual but I manually added it at keypad and it was all good.
Two weeks on ... I wake up to wifi lost again nothing in timeline to say its restored.. so I flick into cameras and it this time says the cameras are all fine. I open them. They all work.. yet no "wifi restored" in timeline.
I go to keypad and my way of checking is to go to system update and it tells me it will only work on a wifi connection indicating the WiFi isn't restored! Yet... how is my cameras operational then...
I then enter wifi password and it says wifi restored in timeline and push email confirms it too.

What is going on......
