I've installed Ubuntu 8.10 on the vmware virtual machine. It was running perfectly, I did what I wanted to do.
In the mornming it proposed me to run updates. There were lots of them - around 250mb, I agreed and after it finished I restarted virtual machine. After that internet disappeared

I have physical machine connected to the switch+adsl modem with NAT and DHCP server. Just "plug and play" version. So I don't need any connection or authorization protocol, just use internet and that's all.

Any ideas how to solve this?
