Hi,

I cannot make my ethernet work though wireless works perfectly.

Thank for any help,

You need to be more explicit. Ethernet is wired. Wireless is not.

If you can provide a little more detail of the problem I am sure you will get some help.

Wifi work but there is no interfaces associated with a wired connection: the only interface of ifconfig is wlan1. So that nothing happen when I plug the rj45.

Can you post the output of
cat /proc/net/dev and
lshw -C network?

So far it seems that your wired adapter is not being recognized at all (it's not in the lspci output). Are you sure it's turned on in BIOS?

Looks like a driver or hardware issue. Try:

I have the exact SAME issue on a Dell e6400 and Dell e4300.
It just started happening in November but was working perfectly in Oct..
bizzare.

how do you reply back with the boxes of your output?

on cat /proc/net/dev
I get:

mudguts, I can clearly see eth0 and eth1 in the output. So what do you mean by saying "exact same issue"?

well.. I have the same hardware and my wireless options are all greyed out.
the wifi 'works' but no connection.

I have dual boot with Win7, in win7, I can connect to my network.. in Ubuntu 12.10, it's just not showing any wireless..

Did you install Broadcom Wi-Fi driver?

You Wi-Fi card seems to be OK but no driver is being loaded for it. That's why it's missing from network interfaces lists.

First, my ethernet card wasn't activated in BIOS.

Second I put in comment b44 in /etc/modprobe.d/broadcom-sta-common.conf which become


# wl module from Broadcom conflicts with ssb
# We must blacklist the following modules:
#blacklist b44
blacklist b43legacy
blacklist b43
blacklist brcm80211
blacklist brcmsmac
blacklist ssb

That makes sense. Thanks for your help. I'll try that now. I wonder why it wasn't loading? It did load for a month or so (.10 release) but then quit in Nov.. bizarro.
