    Question Network problem

    Hello,
    Since yesterday I have a big problem with the network connection using my installed BackTrack5 KDE 32bit.
    Im connected to the internet by wifi...
    Im using a compatible Wireless Card and WICD shows that its connected and that he obtains an IP but when I go to my firefox I cannot see any web page, in all of them I get the message, Server not found
    I've searched about this in google and it seems like it is a name resolution problem (I don't get a DNS)
    the commands :
    Code:
    su -c 'echo "nameserver 8.8.8.8" > /etc/resolv.conf'
    But
    Code:
    ping 8.8.8.8
    shows this message : Network is unreachable

    How about checking which IP you received from the DHCP server?

    I'd be inclined to try the following in sequence to see where the problem occurs:

    ping 127.0.0.1
    ping <MyIpAddress> (displayed by ifconfig)
    ping <DefaultGateway>
    ping 8.8.8.8
    ping www.google.com

    That will give an indication about whether the problem is just on your system (i.e. the TCP/IP stack), one or other of the network cards in your system or the router/modem, the network cable, the configuration of the router/modem or a problem with the connection beyond to your ISP.

    Is it possible for you to enter the configuration screens of the router/modem and ping 8.8.8.8 or www.google.com from there?

    clearly if you cannot ping an IP address (8.8.8.8) this trouble is not DNS related. I strongly recommend attempting a command line wireless connection with wpa_supplicant as it will clearly show you in the output what is going wrong. If there is nothing wrong there, try manually configuring your IP settings.

    use the command route do you have a default gateway setup ? i have had an issue where dhcp in linux doesn't add the default gateway also have you done a ifconfig -a to ensure that you have gotten an ip address. And in regaurds to your dns the whole point of dns is to go from a name to ip if you type in the ip address you bypass the name therefore not needing dns and you have lowered the problem to the network layer

    @sinik - open a shell, run the command <ifconfig> and post the output.
