Can't get internet. (using router)

[Yarr Of Doom]

Ok, now I have Kubuntu, I can't seem to get the internet working. It only gets as far as connecting with the router (TopCom Skyr@cer WBR 354G). Strangely, internet worked just fine when I was running kubuntu from the liveCD.

Check network config (found in Control Centre / Settings), you'll need to click Administration and enter your root password... then check if DHCP enabled?

Also, if that doesn't work, open your /etc/network/interfaces file as root:

kdesu kate /etc/network/interfaces

Make sure it looks something like the following:

auto lo
iface lo inet loopback
address 127.0.0.1
netmask 255.0.0.0

auto eth0
iface eth0 inet dhcp

auto wlan0
iface wlan0 inet dhcp

Add any missing entries, be sure to leave a blank line at the end of the file, save and close the document, log out, press Alt+E to restart your Xserver, and log back in. Then, check to see if you can connect.
