Pi Issue

For some strange reason, the upstairs overwatch cam has been dying quite a bit. Not only did the pi stop working but the wemo upstairs is now disconnected which is strange. I am thinking that possibly there is possibly an issue connecting to the wifi, but will investigate. Hard to believe because it is positioned directly above the router, but I may need to move an antenna. I may also need to assign the address in dhcp, I do not recall if I assigned the new wemo's. My next step this weekend will be to reimage the updstairs pi with the latest image which is on the driveway pi cam. It has been stable since I put it in place to watch the front steps. This pi has been problematic, so I will also check the rev of the pi, possibly it is an older one. I will post an update as soon as I have more to go on, which will not be until this weekend.
