Yang, thank you for reporting this and helping make Ubuntu better. This
bug was reported a while ago and there hasn't been any activity in it
recently. We were wondering if this is still an issue? Can you try with
the latest development release of Ubuntu? ISO CD images are available
from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command in the
development release from a Terminal
(Applications->Accessories->Terminal). It will automatically gather and
attach updated debug information to this report.

apport-collect -p linux <replace-with-bug-number>

Also, if you could test the latest upstream kernel available that would
be great. It will allow additional upstream developers to examine the
issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once
you've tested the upstream kernel, please remove the 'needs-upstream-
testing' tag. This can be done by clicking on the yellow pencil icon
next to the tag located at the bottom of the bug description and
deleting the 'needs-upstream-testing' text. Please let us know your
results.

Thanks in advance.

** Description changed:

  Just installed Ubuntu 10.04 on a Dell Latitude 13 which originally had
- 9.10 working fine. This has:
- 
- - BCM5761e Ethernet
- - BCM4312 Wifi
- 
- Both were initially broken, but I managed to fix the Wifi by installing
- bcmwl-kernel-sources (getting apt to use the install USB was another
- ordeal).
- 
- Now, BCM5761e is still not working. DHCP requests always fail (and the
- DHCP server & network work). Google isn't as helpful for this one.
- Thanks in advance for any help.
- 
- More details follow.

- Code:
- $ lspci -vvnn
