Yeah, that's pretty relevant.  What's happening is that dhclient3 (the
DHCP client on Dapper) is broadcasting a DHCP discovery request over and
over.  It's not successfully communicating with any DHCP servers.  Since
your laptop seems to, there is no problem with the usual suspects --
network cable, switch/hub, etc.  The interval is the just the nth
attempt to broadcast.

Which leads us to  a problem with the NIC

First off, something that puzzles me is that I see conflicting text
here.  In the lines quoted above, you are having trouble getting a
DHCP.  In the lines above that where you copy the ping results, though,
you show that you have an address, specifically 192.168.0.82:
> $ ping 192.168.0.12

> From 192.168.0.12 icmp_seq=3 Destination Host Unreachable 

Not sure why that is.  Did you assign one manually?

Anyway, what do the results of an lsmod look like?
