Linux ospi 3.18.11-v7+ #781 SMP PREEMPT Tue Apr 21 18:07:59 BST 2015 armv7l GNU/Linux
This may be newer than I originally had, not sureIf you are still having issues you might want to look at these two blog posts on Disable Power Management for WiFi and/or USB
I have not done this. I was waiting on results first of apt-get upgrade, and its been two months without loosing connectivity

The idea being that you need to “CREATE” a file /etc/modprobe.d/8192cu.conf to disable the Power Management
RobertParticipantI am affected by the same issue, I think.
I have not had any time to troubleshoot the problem yet but my system becomes inaccessible within one or two days and I have to cycle power to get back in.
It has been like this since I first set it up in June.
The WiFi going to sleep sounds like a good place for me to start looking for the problem.
I think I will bring it all back inside and leave the Pi plugged into a monitor and keyboard until it goes offline again and then check what is not working. -
