    I lost my wireless

    Please bare with me, I am a ubuntu novice.

    I recently installed ubuntu server on a dell inspiron 830. I did this on a laptop only because it was available but everything went perfectly. As I was experimenting with some of the available packages, I suddenly realized that it was no longer recognizing my wireless card. Everything was working fine, when I was plugged in it used the wire, when not it switched to the wireless. Now, it appears to not even know there is a wireless card. One of the networking packages I installed must have corrupted something.

    I suppose I could reinstall from scratch, but that wouldn't really teach me anything. The problem is I don't know where to start in trying to track down and repair this issue.

    So, could I have some suggestion where to look and what to look for?

    Thanks very much!

    Go ahead and run the following commands and post the output, that will help us get some more details.
    Code:
    ifconfig
    iwconfig
    Edit: Also... uh, why did you install the server edition on a laptop? Why not the desktop edition?

    $ iwconfig
    lo no wireless extensions.

    eth0 no wireless extensions.

    virbr0 no wireless extensions.

    pan0 no wireless extensions.

    ------------------------------------------------------------------------------

    If I understand what this is saying, I gather that the OS is no longer even recognizing that there is a wireless card in the machine. How do I go about installing new hardware? Is that the correct next step?

    BTW: The reason for the laptop is simply testing. I´ve played around a little bit with desktop and wanted to try out server and LAMP. The laptop was a convenient piece of hardware at the time. This is not a long term home for it. Just learning...

    Thanks again for the help!

    Re: I lost my wireless

    If found the following command in help. It shows that there is a card there but that it is unclaimed. The help suggested that I use a utility to utilize a Windows driver. I downloaded the driver and the utility and installed the driver however there was no change on the results of the ifconfig or the iwconfig.

    $ sudo lshw -C network

    *-network UNCLAIMED

    Yes, I believe the Intel cards must be supported. When I first performed the install, everything worked great! Wired and wireless. Somewhere along the way one of the packages I tried out must have removed something it should not have.

    How do I ask ubuntu to "re-discover" the Intel card and associate the appropriate drivers?

    Re: I lost my wireless

    I tried installing the free wireless drivers but as I got into it, they did not appear to support intel cards. Is that true?

    Anyone have any ideas how I can have Ubuntu Server ¨re-discover" the hardware on my machine?
