I faced this issue when the 2018 Fire TV stick was disconnecting soon after connecting to the WiFi network. I tried restarting multiple times, switched 2.4/5/ GHz networks, and even restored factory settings, but it was consistently loosing network after a while. Soon I was suspecting some hardware issue.
As a final try, I logged on to my Asus router console and checked for the connected wireless devices. Surprisingly, there was two devices with the same IP address! So there you go - an IP conflict. Never have I experienced a conflict on my router - Asus RT - N66U running Merlin firmware.
Quickly assigned a permanent IP for the Fire TV stick and the problem is solved. A very rare problem and lucky to have it solved sooner than throwing the stick away.
The Fire TV is live and kicking now. Its a tough beast!
