    Well, I'm connection wirelessly to my campus internet and it randomly stopped working. I'm using my computer lab right now... but anyway it actually connects to the internet but then it just says identifying forever and i can't access any websites. I tried just about everything the tech people at my school suggested and they even worked on it for two days and could not figure out what to do. They want to reformat it but I really would prefer they didn't. I recently found something called a static ip address but i dont quite understand how to do it. If anyone has any suggestions or any questions please reply. Also i have windows vista.

    A Static IP address is one that you assign yourself. The default for assigning IP addresses is to use the next available one. e.g. If your router has an IP address of and there are three computers attached to it, then when you try to connect with a fourth using DHCP you should automaticaly be assigned an IP address of
    If you wanted to use static IP addressing then you would bind your network interface to a specific IP address.
    The disadvatage to this is that if someone else on the network is using DHCP and automatically being assigned an IP address, they may get assigned the one you have specified for your machine. As such, when you connect to the network, your IP address will conflict with their's.

    As for a soloution to this, I don't know. I hope that simplified what a Static IP address is though.

    I'd like to see the results of the following tests.

    Try these simple tests.

    Hold the Windows key and press R, then type CMD (COMMAND for W98/WME) to open a command prompt:

    In the command prompt window that opens, type type the following commands one at a time, followed by the Enter key:


    PING <computer_IP_address>

    PING <default_gateway_address>


    PING yahoo.com

    Right click in the command window and choose Select All, then hit Enter.
    Paste the results in a message here.

    <computer_IP_address> - The IP Address of your computer, obtained from the IPCONFIG command above.

    <default_gateway_address> - The IP address of the Default Gateway, obtained from the IPCONFIG command above.

    If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.
