Hi

I am complete newbie to Ubuntu so forgive me of this is a no brainer:

I recently installed Edgy and it worked well.
I had a power cut 3 days ago, and on rebooting, the machine could no
longer access the network.


The machine is connected by ethernet to an ADSL modem/router, and is
configured to use DHCP.
The green light is on the the back of the network card is lit and the
cable is secure.


I have tried altering to a static IP address using the network admin
tool and then back to DHCP but it makes no difference.


I have 2 other windows machines on the network and they work fine, so
the problem cannot lie with the router.



I suspect the sudden power down has messed something up but I have no
idea where to start looking.

1. Ensure that your /etc/network/interfaces is intact.
2. Try to figure out what

# ifconfig ethX

or

# ip addr show ethX

says.

3. Try manually configuring your interface via DHCP with:

# dhclient ethX

4. If the above does not work, try:

# ifconfig ethX ip.add.re.ss netmask net.ma.s.k up
# route add default gw ip.add.re.ss
# ping ip.of.your.gw

Hope that helps!
