@Chris-Stratton , did you see all the picture he posted?
That was exactly my point. None of them show an attempt at using a serial connection.
In terms of being in the wrong subnet, the ssh warning would not have resulted without connecting to something at a 192.168.3.1 running an SSH service, and while that could be a router, the comparably custom address makes it more likely that it actually was the Omega2.
