No network after 'reboot' as a command

I have a BBB running Ubuntu which when powered up picks up its network
address etc, OK from the DHCP server on the LAN and behaves as
expected. If I power down and power up again all works perfectly.

However if I use the 'reboot' command the BBB restarts (well its
lights seem to indicate it's working) but I can't ssh to it and it
doesn't appear on the LAN (an arp-scan can't see it).

I'm using the 'real' ethernet port, I'm not ssh'ing via the USB
connection. The BBB is powered via P9, not USB or power plug.

The BBB is running Ubuntu 13.10

Any ideas what might be wrong anyone?

I think I've fathomed out what was wrong, I had misconnected a router
on my LAN so there were two DHCP servers, not a good idea! :slight_smile:

All seems well now I have only one DHCP server.
