Can't Connect To Internet In Linux Mint 14


I had install Linux mint 14 mate desktop to my laptop few days back.After that i connect to internet using my USB mobile broadband dongle and update the OS.Then i install few software's and drivers.After restart when i try to connect to internet using same usb dongle it connected.Network manager applet shows that it connect to the internet.But when i try to open Firefox it says 'server not found'.I had tried with opera and Google chrome and got the same results.I tried several times after restart the computer and got the same results.
My firewall settings are turnoff.I can connect to internet using same dongle in windows 7.What should i do.How can i correct that error.

Try to ping www.google.com through the terminal and see if it is connected.

Or try traceroute.

#traceroute www.google.com

Ask your ISP's technician what is the Domain Name Server IP. He will certainly give you that ip number, it is a must under the contract. Then, for example, you are given such number as: 88.888.888.88 and your ISP's domain, say, is called forsale.corporation.com you will simply do this in the terminal:

Quote:
echo "88.888.888.88 forsale.corporation.com" >> /etc/resolv.conf
Then restart the internet protocol or network manager.

Launch firefox and see if it can travel now from west to east .

HOpe that helps.

Good luck.

You may create the file. The command I gave above will automatically create the file if it did not exist:

Quote:
echo "88.888.888.88 forsale.corporation.com" > /etc/resolv.conf
Use only one (1) of this " > " it creates a fresh file at the /etc directory.

Good luck.

You could easily
Code:
echo "nameserver ip-of-the-nameserver" > /etc/resolv.conf
And you can check this ip-adress when you have your Windows-box connected to the internet with the same device, execute on the Windowscomputer in the dosshell (cmd)
Code:
ipconfig /all
there will also the DNS-server(s) be listed.
The syntax for /etc/resolv.conf is
Code:
nameserver xxx.xxx.xxx.xxx
nameserver yyy.yyy.yyy.yyy
and so on.
