SD card in Pi3B number one - no problem.
Swap that same SD card to Pi3B number two:
- Connection refused when trying to ssh from another computer.
- No problem pinging the Pi at its new ip (assigned by dhcp) and no significant latency.
- Nmap says 0 ports are open.
Where do I start troubleshooting this? What could be causing ssh to run perfectly fine on one device but shut down on another? Obviously they have different MAC and this dhcp assigns different ips. How could this affect ssh?
Running raspbian Jessie.
