No ethernet after installing 2.6.27-11

[schimschone]

I have discovered that I have no ethernet support under the new kernel (2.6.27-11), however it works fine under the previous version. I have restarted several times, and I have tried reinstalling the new kernel.. still nothing.

Here's my chipset:

Broadcom Corporation BCM4312 802.11b/g (rev 01)
Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E PCI Express Fast Ethernet controller (rev ff)

and I'm on a Dell Mini 9, running x86 version of 8.10, if that helps.

At this point I've simply reedited GRUB to run the old kernel on startup.

I'm open to any suggestions.. even the possibility that I missed something.

Thanks ahead a time, btw.

what happens if you do sudo dhclient eth0 in a terminal?

Here ya go:

"Listening on LPF/eth0/00:21:70:d0:e6:98
Sending on LPF/eth0/00:21:70:d0:e6:98
Sending on Socket/fallback
DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 8

DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 14
No DHCPOFFERS received.
No working leases in persistent database - sleeping."

I have no idea what all this means though.. while I'm not a n00b I would probobly count as a n0b.. but I'm learning.

when you right click on the network icon top of the screen does it say manual configuration? If that is the case you may need to reset the network configuration file

[abn91c]

If you want to configure DHCP address you need to edit the /etc/network/interfaces and you need to enter the following lines replace eth0 with your network interface card

sudo vi /etc/network/interfaces

# The primary network interface - use DHCP to find our address
auto eth0
iface eth0 inet dhcp

I can confirm the problem on a LG X110 Netbook.

Setting dhcp in /etc/network/interfaces doesn't help.

I doubt it's an configuration error because the same configuration works with kernel 2.6.27-10-generic.

Unfortunately it isn't even seeing that an ethernet cable is attached, thus there is no 'manual connect' prompt, and 'Auto eth0' just searches for the etehrnet connection without finding it .. at this point I think I'm sticking with 2.6.27-10 until these issues are ironed out, but I'm still open to any ideas.

Well as of the last time I checked.. about an hour ago, this problem has not been resolved through update. Now while I appreciate that we live in a wireless world, it seems fairly significant that ethernet support has been lost by at least a few in the community.

Any ideas would be appreciated, and while I am n00b-ish, I am willing to learn. So again I holler into the electrical press and say "help".

Maybe it helps if i give some extra information about what i was able to find out so far.

It seems that the interface looses the ability to sense a cable.

The kernel sees the interface as always up although no connection to the switch exists.

once again i'll post the hardware information and kernel logs.

The only difference i could find was this strange link up during boot without a cable connected.

Thats it from me. Maybe im just not seeing the simple solution, but i dont have the time right now to search for the problem myself.

I can confirm same problem on an Acer Aspire One running 8.10. Kernel 2.6.27-10 work, 2.6.27-11 no Ethernet, wireless ok.
