Wired connection in Network Manager and eth0 interface disappeared

[obik]

hello, I am new here and have a problem with my wired connection. recently it just disappeared :/ I think it could happen while unsuccesfull hibernation. I was trying to search solution but every one found failed.

my ifconfig

does someone know what is wifi0 and why its mac is so weird?

/etc/network/interfaces :

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp


/etc/init.d/networking restart:

* Reconfiguring network interfaces...

help please.

Wish I could check my system... otherwise my guess is even wilder. Might try killing the process 134519120, then restarting networking again.

[obik]

This didn't worked.
bash: kill: (134519120) - No such process

[Iowan]

Do you actually have wireless - or is something being misinterpreted?

[muximus]

try the following:

ifdown eth0

then,
ifup eth0

[obik]

Do you actually have wireless - or is something being misinterpreted?

Yes I have wireless, the problem is about wired.

my ifdown eth0 says:
ifdown: interface eth0 not configured

[Iowan]

More things to check:lspciifconfig -admesg |grep eth

and no reply from "dmesg |grep eth" :(
thanks for interest.

Your wired Ethernet controller is not appearing in lspci, which is ominous...

Is there a setting in the CMOS (BIOS) setup when the computer first starts to disable on-board peripherals? Maybe it got disabled in the hibernation problem you had.

What kind of computer is it?

[obik]

it's toshiba satellite l100 laptop. I will check this setting in bios right away.

EDIT:there are some settings for LAN. it's "Built-in Lan" option which was enabled when I checked.
