Unable to establish wired network connection (Dell Inspiron)

[sourav7mishra]

Hi all, I have an issue relating my broadband connection, which I am not able to solve. I hope and wish, that I would find some way out here.

Some introduction: I am using Dell Inspiron (i3 processor) laptop, which I recently bought. I have win 7 preinstalled in it. In win 7, the wired broadban connection (Airtel connection) is working fine and have no issues.

I have been using mobile GPRS(BSNL, Ltd) through bluetooth, and that have been working fine. But today when I tried to connect through landline connection, it didn't workout. But the bluetooth connection is still fine. When I tried to do the connection manually through Network Manager, it is not taking the MAC Address. Till now, after installation, I have not updated my OS.

I surfed the net and tried some commands, whose results I am posting below. If any body get some clue, please help me out.

From a post I found out, that I should change my duplex settings (from 100 full to 10 full), but I could not get much. The corresponding commands and output, I have posted below:

[sourava@localhost ~]$ dmesg | grep -i duplex
[sourava@localhost ~]$ ethtool eth1
bash: ethtool: command not found
[sourava@localhost ~]$ mii-tool
SIOCGMIIPHY on 'eth0' failed: Operation not permitted

SIOCGMIIPHY on 'eth5' failed: Operation not permitted
SIOCGMIIPHY on 'eth6' failed: Operation not permitted
SIOCGMIIPHY on 'eth7' failed: Operation not permitted

Any help would be appreciated much.

Did you try running system-config-network to set up the eth0 interface, it looks to me like it's completely missing


BTW, you can find ethtool in package 'ethtool'

yum provides \*/ethtool

I think, my eth package is missing.. I tried:

[sourava@localhost ~]$ ifconfig eth0
eth0: error fetching interface information: Device not found
[sourava@localhost ~]$ ifconfig eth1
eth1: error fetching interface information: Device not found

I also tried system-config-network, but couldn't g et any option, apart from dsn settings....

If possible, please guide me how to install the eth0 package.....
