network failure on kubuntu 6.0.6

[eXecutioner]

I have a pretty strange problem on kubuntu...
I'm using Windows XP and Kubuntu.
I had a problem with my windows xp and formatted this partition. I didn't know how to replace the GRUB so after I installed windows again I installed kubuntu on the same partition as before. After that I can't get acces to the internet any more. Any ideas?

May sound silly - but: did you (manually) setup the network past reinstallation?

My network card is Realtek RTL8168/8111 PCI-E Gigabit.

The thing is that the first time when I installed kubuntu it worked perfect... I didn't have to configure anything. After I formated the partition even the Live CD was not able to connect to the Internet and could not install the security updates.

My /etc/networks/interfaces looks normal... Just it has like 5 interfaces... Is this OK?

I got an ifconfig result here:

simply put you do not have an ip address which is needed to connect to the internet. go into systems settings, click on network settings, click on admin, and make sure your NIC is set to dhcp.

Sound to me like your dhcp is off

k menu than, system settings than to your network settings. than login as root than, network interfaces

make sure the tcp/IP is automatic and set to dhcp than click apply if not just reboot your Linix box. try to connection to the internet.

if no connection check your domain name system tab depending on howe your ISP works you should see at least one DNS in the domain servers list.

here is a copy of my ifconfig to let you see a working connection this is a wired
connection.

let me know if you have any luck

post ifconfig again so I can see the result
