Went on a trip out of town this past weekend and while I was away my Raspberry Pi server lost connection to the WiFi network in my home. My wife told me there had been some brief disruptions in power, so I assumed it had not booted properly and just figured I would wait until I got home to troubleshoot. What I found is the Pi booted just fine, but for some reason dropped connection to the network. A search on google found several sites of information from other people who have had the problem, one that suggested disabling Power Management made sense, particularly after I found Power Management was on. Ever since I made the chance the Raspberry Pi has maintained connection, so hoping this did in fact resolve the problem. #
