resume from network interuption in ubuntu

"Hi guys I am using Ubuntu 9.04. Things are cool, except for the annoying part about networking.
Say, if I am connected to a LAN cable, and somehow the connection is lost (let it be network congestion or my kicking the power cable), I will then be unable to get connected again.
I tried restarting the modem, unplugging and replugging it, clicking the network icon and telling it to connect, but the only thing that works is to restart the computer.
I know Karmic will be out in a few days but there's no warranty that the problem will be gone. So please tell me why and how to fix this, or at least some workaround (so that I don't have to restart the whole PC).
PS: everything is fine under Windows, which means it's not a hardware fault."

Run "tail -f /var/log/messages" before replugging your network cable. What messages appear? What if you run "sudo ifconfig eth0 down ;sudo ifconfig eth0 up"? Again, what messages appear in /var/log/messages? What if you run "sudo dhclient eth0"?
