Bug Description
Binary package hint: network-manager
The bug occurred after upgrading to jaunty.
I'm not sure about the network-manager, it could also be the kernel, a driver for my network card,
or perhaps the cause in the reorderings done to increase the booting speed in jaunty.
Also I expect this to be duplicate bug, but I couldn't determine an existing one that was really close enough.
I reported this earlier at this existing report, but then found that ubuntu-bug is preferred, so
I'm repeating this here:
can't connect via dhcp
https:/
After boot using the default kernel there is no wired connection to the internet, but everything on the local network is available. (ping by name to local machines works, but pop for email fails.)
If I did not have another machine on the local network, I would have had no way to know how to fix this, as this isolates the upgraded machine from the internet.
I can always correct this by doing:
sudo ifdown eth0
sudo ifup eth0
Since this is repeatable, I'd like to hunt it down to the source of the
problem, but I have no idea how to proceed.
The network icon in the system tray does not show an active network
(neither wired nor wireless) before and after the ifdown/ifup fix.
Any suggestions as to what I could do to fix this?

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/
- 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://
