There are so many causes of loss of Fusion connectivity.
Many of the solutions mentioned already will fix it, but only for some.
With my first Apex, I had Fusion connectivity issues until I put the Apex on a UPS.
Thereafter, no connection issues directly related to the Apex.
Later, as I added many devices to my home network (about 50 currently), my Netgear Nighthawk router just couldn't manage it.
Switched to an Orbi mesh system, and everything just magically started connecting properly, with decent speed, and all the time, as they should.
Sometimes a new router is the answer.
Setting a static IP address in the Apex and a complementary DHCP reservation in your router are both good ideas.
Avoids any confusion about what device is on what IP.
I don't think you need a hardwired connection to your Apex at all. My connection via Wifi is lightning fast.
I'm frequently amused when I do something unexpected in the tank and Fusion on my phone notifies me a second later.
I had a similar situation - it was extremely frustrating - using the Wifi from the Apex - it would work 'great' for days - and then all the sudden would disconnect maybe 50 times/24 hours. restarting it made it work again - and then a couple days later it would do the same. After every power outage (even a small one) - it would not reconnect to fusion (or if the apex was unplugged). I decided to change to a network extender - and its never disconnected again. So - it might have been signal strength - but this is a very widely reported issue - and it seems like some units are more unstable than others ??
