The OctoPi install does not keep WiFi connection. Tried multiple times with different placements. The issue seems to be signal strength with the Pi adapter shutting down if there is not enough signal strength. I suspected lack of activity based on other users reporting similar issues. The other reason cited seems to be insufficient power supply issues. But that was ruled out by trying different wall warts with same disconnection issue persisting. Only time the Pi kept the connection for a length of time is when it was close to the router.
