How to keep ethernet or wifi connection live in sleep mode on Blade

I have a Razer Blade 14" (2017) model behind a router (Apple Time machine) sitting at home, which I'm trying to connect via ssh through the internet in when the Blade is in sleep mode by using Wake on Lan via wifi or ethernet. However both Wifi and ethernet have different issues with the Blade's sleep mode, and hibernation disabled by setting the timer to 0 min (never). 1. via Wifi - Blade loses wifi connection sometime after going to sleep, not right after. I believe it randomly loses connection, which happens when I'm playing games on it too. - Is there a way to make the wifi connection more stable? I found many with the Killer network adapter is facing the same issue. - Or make the Blade try to reconnect wifi during sleep? 2. via Ethernet - Ethernet connection immediately loses connection as soon as Blade goes to sleep. - The cable is connect via Blade's USB-C port using a USB-C to ethernet dongle. I can see the dongle's green light turn off as soon as the Blade goes to sleep. Tried various ways to keep the USB-C powered on during sleep but none worked. Any ideas how to make this work? Please help!
