Kubuntu can't enter the Internet

[HermanDegenhart]

Hallo, the evening before Kubuntu just went fine when I closed my machine, the next morning however my computer could not contact to the servers to get my mail. It must be a Kubuntu problem as my Windows computer could get through. Thanks Bill, but what a shame. I know there are some Windows only programs to solve this issue, but how to solve it in Kubuntu?

Re: Kubuntu can't enter the Internet

did you test the servers @ the same time of each other? ie: ubuntu vs. windows?

Re: Kubuntu can't enter the Internet

As I have place for only one computer at a time on my desk, its either my Vista computer or my Kubuntu computer that is connected (by wire) to my modem. When I use my Windows computer I can get through to the Internet, but suddenly my Kubuntu computer cannot.
My modem is an Allied Data Copperjet 1616-2p. In Vista Network Connections obtains an IP-address automatically as well as a DNS server address if needed. How does Kubuntu handle this?

If you are using knetworkmanager please check your /etc/network/interfaces - it should only contain the following:

auto lo
iface lo inet loopback

If anything else is in there, delete it and your problems should be sorted after a reboot (or perhaps even a sudo /etc/init.d/networking restart).
