    Are you using broadband? Wired or wireless?
    If you're using a router and you know its IP address you can try manually giving an IP address to your PC but it has to be in the same range as your router. That is if your router's IP is 192.168.1.1 then you'll have to specify something like 192.168.1.2 to your PC.

    You may want to try taking a look here too.

    please would you do the following, if you can copy the results to the computer which is working - the easiest way is via notepad using a usb stick if you have one


    ------------------------------------------------------------------------
    ipconfig /all
    If you cannot access the internet with this PC, then you will need to paste the results into something like notepad and then copy onto a machine that can access the internet and post results here
    We would like to see the results from ipconfig /all post back the results here
    -> Start
    -> (XP - enter the following in the RUN box)
    cmd /k ipconfig /all
    -> (Vista or Windows 7 - enter the following in the Search box)
    cmd /k ipconfig /all

    A black box will appear on the screen -
    rightclick in the box
    select all
    enter
    control key + C key - to copy

    then reply here and
    control key + V to paste

    A quick fix is to uninstall the driver and then reboot the system. Let the OS re-install the driver and the system should be able to get a new DHCP IP. If that doesn't happen then either the device is bad or something is wrong with the router in question. Either power cycle the router or do a reset. If that doesn't work then download the latest firmware from the router maker site. If that doesn't work then go and buy a new router.

    Note: Did it work prior? Did anything change prior? Have you scan for pest on the system lately?

    if you know the IP address of your router just type it in your browser the IP address is also available in CMD if you issue the "IPCONFIG /ALL" command. the ip address usually are 192.168.1.1 or 192.168.1.100. the username and password will mostly be "admin admin". from there set your IP address. usually a range is specified in the router. give your pc some ip from that range. specify the DNS if you have it or set it to automatic.

    if this dosen't work use the above method to uninstall and then reinstall. If you can callup the ISP ask for the DNS adresses
