    A few days ago I lost my internet connection. After rebooting my laptop (2004 Dell Inspiron 5100), my cable modem and my wireless router to no avail, I called Cox, my internet provider, and they had me do some troubleshooting.

    Results of ipconfig:

    Because of the bad ip address (192.168.1.137), Cox had me do an ipconfig/release:

    Microsoft Windows XP [Version 5.1.2600]

    Windows IP Configuration

    No operation can be performed on Local Area Connection while it has its media di
    sconnected.

    The above message made me look twice at the results of the ipconfig, and I noticed for the first time the part about the ethernet adapter. Cox had me physically connect my laptop to my cable modem with an ethernet cable - no luck. At this point Cox informed me that this is probably a hardware problem. Do you agree? I've noticed you typically request an ipconfig/all, so:

    The local Data Doctors shop told me by phone that if my ethernet adapter is indeed bad, I would have to replace my entire motherboard. I'd welcome any suggestions as to what else the problem might be. Thank you!

    Watch out, Terri! I think they want to sell you a certain bridge in Brooklyn also. :)

    If your NIC is bad you could buy a new computer, replace the motherboard, or just buy a PCMCIA ethernet adapter for $20 -$40. Or even a not-quite-as-good USB ethernet adapter for around the same price.

    Please do the following three things; for the third please try to connect to the router by both wireless and ethernet at the same time.

    1)
    Start - Run - ipv6 uninstall - OK

    2)
    (From a JohnWill post)

    TCP/IP stack repair options for use with Windows XP with SP2.

    Start, Run, CMD, OK to open a command prompt.

    Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

    Reset TCP/IP stack to installation defaults. netsh int ip reset reset.log

    Reboot the machine.

    3)
    Start, Run, CMD, OK to open a command prompt:

    Type the following command:

    IPCONFIG /ALL

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

    If necessary use a text file and removable media to copy the results to a computer with internet access.

    I'm in the process of doing the first two. Thank you! And yes, I'm doing the "copy to Wordpad/save to thumb drive/copy to forum post." Fun :) but better than the alternative!

    Question for you - and I'm sorry if this is silly. The 'PCMCIA ethernet adapter for $20 -$40. Or even a not-quite-as-good USB ethernet adapter for around the same price' you mentioned - is that the same as a mobile broadband card or USB modem broadband card? Because I have the latter on my work laptop, which is what I'm using right now with you.

    It didn't occur to me to try it on own laptop because I thought it served the same purpose as, for example, a cable modem - it provided me with internet access. It seemed to me that since my ethernet adapter was bad, it wouldn't matter HOW I tried to access the internet, my laptop's hardware just wouldn't finish the connection.

    Could I use that after all? Although I'd rather go get an insertable card - I don't like the speed I'm getting with the USB modem.

    Sorry - I missed the part about trying to connect to the Internet via wireless and ethernet cable at the same time. I just did that, but the ethernet cable connects the wireless router to the cable modem, so by connecting it to my laptop, I can't really even hope to connect to the Internet via the wireless router because it's not receiving any signal.

    I attempted to connect to the Internet while connected to the cable modem via the ethernet cable - no luck. I tried again after reconnecting the cable modem to the wireless router, still no luck. I do, however, have a good IP address again - sort of . . .

    I think we are confusing each other somewhat. I want to see an ipconfig /all for the laptop connected to the router via wireless and ethernet. It doesn't matter if the router is connected to nothing else, I just want to see if we can get successfully connected to the router one or both ways. We can worry about internet later.

    You have ICS enabled, and we may as well get that out of the way. For each connection please do:

    Network Connections - right click on the connection - Properties - Advanced tab - if Internet Connection Sharing shows make sure that it is unchecked. (Repeat for each connection.)

    Before trying to connect, if your wireless network is encrypted, disable encryption on the router.

    Also, when you connect an ethernet cable between the laptop and modem or router, does the LED by the ethernet port light up? If not, please connect the cable, make sure the laptop is on A/C power, and boot or Restart it. Reason is that some laptops will turn off the ethernet to save battery.

    Did not have ICS enabled on any of my connections. I'm heading to the back room where my modem & router are to try your request again about connecting.

    And no, my USB modem doesn't look anything like that - I think I was right - about something, at least. :)

    Back in a flash.

    And no, the ethernet LED on the wireless router did not light up. I rebooted and it's still not on.

    By the way, Terry, I really appreciate your help. If I can go buy the adapter you mentioned for $30-$40, I'm ready to go do that now. I've already spent twice that in time working on fixing this one, and it's 10% of what I would have paid had I listened to Data Doctors.

    Thank you SO much - I think I'm heading to Best Buy or Circuit City! I love Tiger Direct, personally, but if I can get this up & running tonight I'm all about that!

    After doing my due diligence online, I purchased a Belkin Wirelsss G Plus MIMO Notebook Card. You recommended a PCMCIA ethernet adapter, but I'm wireless and want to stay that way, and figured you just hadn't taken that into consideration and were, rightly, letting me know my options for replacing the part that had failed, which I appreciate.

    Anyway, I got it home and installed the Belkin and still couldn't connect. I'm getting the "limited connectivity" message for my wireless connection. I don't understand why I have to have an ethernet connection on my computer when I have never, ever been connected by an ethernet cable, but for some reason, my wireless won't work while my ethernet "media is disconnected." If you recommended the PCMCIA ethernet adapter because it IS necessary, I guess I wish you would have stated that. All I can do now is return the Belkin, buy an ethernet adapter and install it, and then hope my wireless works again.

    I've been concentrating on the wrong problem. Don't always pay a lot of attention to titles, but yours complained about 'Media disconnected' and your original ipconfig shows the ethernet disconnected and the wireless with a messed up configuration. If you're not worried about the ethernet then I have no problem forgetting it.

    We did make progress on the wireless. With the stack and WINSOCK repairs and the ipv6 uninstall the wireless config at least looks reasonable.

    The problem is that it is not finding a Dhcp server; and somewhat worrisome is that one of your ipconfigs showed IP of 0.0.0.0.

    A common problem is encryption mismatch. Suggest you make sure encryption is disabled on the router, do the repairs again (some people have had success after 2 or 3 interations), try to connect with the integrated wireless and show another ipconfig /all.

    You could also then disable that wireless connection (in Network Connections) and try to connect with the new card and show an ipconfig /all.

    I'm seriously ready to just give up and buy a new laptop. He had me uninstall the drivers for both the ethernet & wireless adapters, then reinstall both, run "msconfig" and remove a bunch of items from starting. Now when I do an ipconfig, both the ethernet and wireless adapters are showing "media disconnected."
