backtrack5 r1 internet connection (server not found)

[psv8]

Hi, guys.
i've got this problem.
I installed backtrack5 r1(gnome), and when i open mozila firefox i can not connect to any sites.If i do apt-get update/upgrade its can ot connect it as well. WICD shows that i am connected to my router. I ve got double boot BT5 KDE and everything is ok on the same laptop.
I thought it is "no script" blocking it, but it is not. I checked my firewall options,still the same.
please help me as i am strugling with this for the third night.
Thank you for you help.

Are you trying to connect wirelessly, or wired? DHCP or static IP?
Have you tried to ping anything to verify connectivity?

ping www.google.com
ping 74.125.91.103

Hi, thanx for reply.

I am trying to connect wirelessly and have static IP.

ping google
ping: unknown host

ping 74.125.91.103

Looks like you do not have resolv.conf setup. Try adding your ISP DNS server to this file.

File should look something like this:

search your domain
nameserver ISP DNS Server 1
nameserver ISP DNS Server 2
nameserver ISP DNS Server 3

If this is setup ensure you can ping and resolve something form the ISP DNS servers.

Hi, guys.
Thanx for your reply. I very appreciate it.
I have sorted my problem, i do not know how i did it. Any clues?

I had a hint from jayd512 "Do you have DHCP or static IP?"
I connected my laptop through the cable to my modem and it was working. Than i disconnected the cable and everything has been fine.I do not know what has happend, but now i have internet connection.
So thank you very much guys and if you know what had happened please post it

Most likely, when you established a wired connection, your /etc/resolv.conf file updated.
You were connected before, you just didn't have any DNS servers in your configuration.
