Hi All,
I am unable to get internet using Firefox web browser in my CentOS 6.4 where as in windows 7 I am getting internet. Should I uninstall Firefox, in that case how?
Waiting for suggestion.
I have very little knowledge about linux.

First of all you should check if you haven't a connection at all with

Code:

ping 8.8.8.8

or

Code:

ping duckduckgo.com

Any IP or domain of your choice.
If all packets got lost you have to configure your Network Interface.

To configure your Network Interface you must find out the name of your Interface with:

Code:

ip link show

Your ethernet Interface should look like:

Code:

2: enp9s0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000
    link/ether 00:24:54:c5:f6:f6 brd ff:ff:ff:ff:ff:ff

So here enp9s0 is the name of your Interface, remember that.
Now you have to change a file via sudo with a text editior e.g. nano or vi. I would recommend nano for you.
So login in as root and edit:

Code:

nano /etc/sysconfig/network-scripts/ifcfg-enp9s0

Change "enp9s0" to your own interface, that you found out via ip link show.
Now change, ONBOOT=no to ONBOOT=yes, then you can save file by pressing Ctrl+O and close by pressing Ctrl+X.
After a reboot your network interface should work.
You can test it by

Code:

ping linuxquestions.org

again.

you are aware that the version of firefox that is installed from the install dvd is firefox 3 ,and the current firefox is 25

also how is CentOS installed .It is a server class OS and as such it really not a good choice for say a HOME install and a worse choice for a laptop install

so
desktop?
or Laptop ?

is this a dual boot with windows7
or a single install
or
is this a virtual install and not a real one ?

Are you using Wireless ?
if so what ?
centos dose not support many wireless devices

or if wired ?
what ?
56k dial up ?
dsl?
dsl2?
cable?
fiber?

Find out what your default gateway IP address is in Windows by using the ipconfig command on the command line.

Then, from your CentOS operating system, attempt to ping your gateway IP address. If you can ping this address, you know that your network interface card works correctly.

I would also suggest him to update his firefox.

I have installed centos on my laptop and to honest I think it works way better than the mint installation I had on first I would not say centos is bad for a laptop installation.
