What is the exact error message for "no server found"? Is name resolution working; what happens if your try this at a command prompt

Code:

ping linuxquestions.org
ping 75.126.162.205

You might also want to check to see if you have a local DNS server running:

Code:

$ ps -e | grep -i dns
 1629 ?        00:00:00 dnsmasq

If - for some reason - you don't, try rebooting. Your local DNS server should be automatically started during the boot process.

the server error is no server found, check tiping www... etc.
i tried ping 75.126.162.205 it says destination host unreachable...
i have no clue???

It would help if you were more specific, ideally copy-and-pasting the command prompt text into this thread. It's easier to read if you put it in code tags (that's a link to instructions or you may prefer to use "Advanced Edit" mode which has a # button for code tags).

The output from the route command might help, too.

Are you sure you're connected to the Internet from your Linux system? What does the output of the ifconfig or nm-tool look like?

Code:

$ ifconfig

Note: I highlighted the local and virtual machine addresses in red, and the Internet connection in green, in the above output. If you only see local addresses in your ifconfig output, you have no Internet connection.

What exactly are you connected to?

Evo2.

We could help you better if you answered our requests for information.

Please offer proof that the above statement is correct. Without any proof, why should the statement, alone, suffice?

By "proof" I mean something like my prior post, or, at least, a statement that you ran the ifconfig command and saw a valid IP address for an active connection. (If you did that, what IP address did you see?)

Note, please, that the light on your computer that turns on when the wireless modem is on does not tell you that you're connected. It's only there to tell you that the modem is powered on and, in some cases, aware of an access point.

Note also that your ability to connect from a Windows system does not prove anything about a connection from a Linux system, except that there is no obvious hardware problem preventing a connection to the Internet.

Additionally, note that terse, one sentence, posts are seldom viewed as informative or responsive.
