I managed to solve my WoL issues by adding a WiFi/smart power outlet to my setup, and connecting one of my peripherals to it. After noticing that power cycling the peripheral (in my case, an audio interface) would wake my MacBook Pro when it was in sleep mode, it occurred to me that it would be much simpler and more reliable to wake my system this way than by using Wake on LAN, which had proven to be intermittently reliable - even with everything configured properly to use the feature. Since discovering a hardware disconnect/reconnect always seems to wake my MBP, I've stuck with this method. One might be able to do the same with something other than audio device peripherals, but I've had no need to test anything else to see what works vs what doesn't. relevant system specs: MacBook Pro 15-inch, 2017 (MacBookPro14,3) macOS Sierra 10.12.6 Apogee Ensemble Thunderbolt (my audio interface)
