[Bug 581240] [NEW] cannot connect to router via ethernet - lucid

[Glen Shennan]

Public bug reported:

I have been using 10.04 AMD64 on my desktop since its release.  The
network was working fine.  Recently I booted and the network manager
shows no connection.  Tried every fix I could find and then tried a
clean install.  When I booted from the LiveCD the connection was again
not found and the clean install still couldn't connect.  Kubuntu 9.04
LiveCD makes the connection no problems but Kubuntu 10.04 does not.

'sudo lshw -c network' produces
