Hi everyone

I am not usually used a wired network so I didn't notice that in my NetworkManager there is no a wired network. Now I need to use this at work but even when I plug the wired, my computer seems to not even recognize it. Wireless connection works perfectly.

Here some outputs:

According to the above output, your ethernet hardware isn't recognized at all. The lcpci output seems to be for your wifi module, (using the iwlwifi kernel module).

Please update your question with the complete outputs of lspci and lsusb.

If you have a liveCD, please test it out. It could be a hardware error too.

@Ale: as you see from the outputs of your commands, your ethernet hardware doesn't seem to be detected by the system at all. I suggest you grab a liveCD and run the same commands to see if your ethernet hardware is detected there. If it isn't, I'm afraid it's a hardware issue. Please try a Fedora 19 liveCD or another Linux distribution and confirm the hardware works.

If a configuration file for wired network is not present, you can create one like below. Use any editor to create the file.

vim /etc/sysconfig/network-scripts/ifcfg-eth0

ONBOOT="yes"
BOOTPROTO="dhcp"
IPADDR=
PREFIX=
GATEWAY=
DNS=

then restart the network

service network restart

thanks, but I didn't work. :( Well, actually after I run service network restart I found: sudo service network restart Restarting network (via systemctl): Job for network.service failed. See 'systemctl status network.service' and 'journalctl -xn' for details. [FAILED] algomez@adelle:~$ systemctl status network.service network.service - LSB: Bring up/down networking Loaded: loaded (/etc/rc.d/init.d/network) Active: failed (Result: exit-code) since Tue 2013-06-11 11:14:09 EDT; 14min ago Process: 4604 ExecStart=/etc/rc.d/init.d/n
