Okay, the first thing you have to do is establish a link. Check both ends
of your network cable to make sure it doesn't look worn and that it is
fully plugged in. You will probably see little lights turn on when the
connection is good. If needed, replace the cable or get assistance from
your network person.

Make sure its resolv.conf, and not resolve.conf.

Cable is perfectly OK and plugged in properly with other systems but problem still not ok even I am unable to ping my WAN gateway everything is like normal but I don't know where I did mistake. I install a fresh os copy but problem is still there.

Hi,

mii-tool should report "link ok" if not check your cable connections.

Issue the below command and check for RX and TX for the particular interface the value should keep changing.

watch -n 1 "netstat -i"

My problem has been solved infact I was misread card name i.e. I was understanding eth0 is eth 1 and vice versa thanx for help.
