I am running my Pi headlessly, connecting via SSH over the network. I am having a problem that I can consistently reproduce. I will leave a Python script running on my Pi and come back a few hours later and SSH connections to the Pi will time out.
If I ping it I get the following:
C:\Users\andrew>ping 192.168.1.42 Pinging 192.168.1.42 with 32 bytes of data: Reply from 192.168.1.46: Destination host unreachable.
The only way I can get it back on the network is to restart it (pull out the power).
Has anyone experienced this? Are there any log files I can look at to diagnose the issue?
