It is similar, with a difference that /etc/init.d/net.eth0 restart
doesn't help. I tried
enlarging timeout but with no help.

I noticed that in most cases after I boot to windows, when I reboot
back to linux I can't connect.
When I reboot back to windows, net is up.

When it fails I noticed that it send DHCP requests, but doesn't get a response.

I tried dhclient, dhcpd and pump, and the results are allways the
same. It happens in the evenings, when internet traffic is high.
