Yup, I went in and out of every menu option I could find on the router. Tried turning off the various protections short of the general internet firewall, tried assigning a static IP to both devices, changed the DNS to Google's 8.8.8.8, tried the various WiFi speed options and so on. I've learned a lot about routers and WiFi if nothing else
No timed access options that I saw.
What puzzles me is that our 64 GB iPhone 6 works fine, as does my iPad Mini. It's just a problem with my 16 GB iPhone 6 and my MacBook.
After months of troubleshooting, I'm nowhere... so was just hoping maybe someone would think of something "out of the box" I hadn't tried yet

The new router I'm putting in tonight may fix it, but I hate not knowing the actual cause of things so I can avoid them in the future.
The nasty thing about it is it won't failover to cellular when it happens, so I wake up, look at my blank lock screen and think, "Cool! No work problems overnight!" Then later I try Safari or something and realize it's been disconnected all night, toggle the WiFi, and the flood of work emails come in
