Hi!

I have simillar problem. I think is a kernel / network driver issue.

My setup is, laptop HP nc6400 + Ubuntu 9.04 upgraded from 8.04 where everything was OK.

Network card: Broadcom Corporation NetXtreme BCM5753M Gigabit Ethernet PCI Express (rev 21) as eth0.

I do not receive ANY PACKETS and problably no packets gets to router (i've checked logs for DHCPREQUEST on the router). I assume that by output of `ifconfig eth0`, where received is 0 and sent is changing +2KB for each `sudo dhcpclient eth0`. I just cant say what's going to my DHCPREQUESTS packets, something is

I can't even set static inet IP, i've tried:
- by NetworkManager
- editing /etc/network/interfaces
- editing dhcpclient dhcp.conf file and setting alias for my eth0

The thing is odd because hopefully my WirelessCard send/receive DHCP OFFERS and REQUESTS :)

Any other computer in the network do not have problems with getting IP from the router (Windows XP machines).

PS: I've tried this method http://www.prash-babu.com/2009/05/how-to-fix-ip-by-dhcp-issue-in-ubuntu.html and that did not change aything.
