Dear ubuntuforums users,

I have been lurking around for a while, reading support requests and learning a bit here and there.

Yesterday I rebooted and unfortunately my wired connection simply stopped working.

I am running latest generic kernel (2.6.24-19) on hardy.

Understandably this is less than what is necessary for you to help me troubleshoot the problem, so here's a bit more:

lshw -C network:
Code:
  *-network               
       description: Ethernet interface
       product: L2 100 Mbit Ethernet Adapter

       logical name: eth0

       serial: xx:xx:xx:xx:xx:xx

       clock: 33MHz

       configuration: autonegotiation=on broadcast=yes driver=ATL2 driverversion=1.0.40.2 firmware=L2 latency=0 link=no module=atl2 multicast=yes port=twisted pair
(note: previously this has shown *-network DISABLED
to enable I used 'ifconfig eth0 up')

ifconfig:
Code:
eth0      Link encap:Ethernet  HWaddr xx:xx:xx:xx:xx:xx

dhclient eth0:
Code:

DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 2
No DHCPOFFERS received.
No working leases in persistent database - sleeping.
dhclient gives the _same_ result when the cable is plugged in and when it is out.

I get no lights whatsoever from the built in network card, but my second boot (windows xp) lights are up and everything is working (as you can see; because I am writing from it).


I will appreciate any help.

Thank you!
