Ubuntu stopped connecting to Internet

[Ari Torhamo]

Hi,

Heeeelp! Ubuntu just stopped connecting to Internet without me in any way messing around with the system. First I suspected my ISP, but they checked the line with their tools and told that its either my ADSL-box or the operating system. That's when I came to think of booting to Windows and the connection works fine here (I'm at windows now).

At the boot I get the following error message:
Configuring network interfaces...
Setting up freenet ipv6 tunnel (sit1)
cannot find host, resource temporarily unavailable
I tried to activate the connection in network settings, but it didn't work. I have tried booting and activating the connection several times without success.

BTW, the ISP technician said that from there it looks as if I had three computers connected to the net. When I told him that I only have one, he said that something is not right there.

Can anyone help?

Ari
