Every linux system I've ever seen always automatically clears dmesg on every 
boot (I've never done a -c, but always only see 'current' messages).  dmesg 
usually only has driver initialization messages though.  You can check 
/var/log/messages, but on ubuntu I think most things go instead to 
/var/log/syslog

You could probably get the message again if you do one of these two commands:

sudo /etc/init.d/network restart
or
sudo /etc/init.d/NetworkManager restart

(that's what they are on Fedora, I assume they're the same/similar on Ubuntu...)
