    I've been having periodic power outages for the past few days. My family's Belkin wireless G router had been working fine with the Trendnet network adapter installed on my laptop before the blackouts, but now, not so much. At first, the adapter would not connect to the router at all, with the error message that there was "no Network Address assigned to this computer"; now it "connects" to it, but with no internet connectivity. I've tried altering settings in the firewall, switching between static ip and DHCP, even just turning the router and modem on and off, and still nothing. We have a Verizon DSL line and modem. My laptop is a Dell Inspiron 1200 running Windows XP... Not sure if I have SP 2 installed or not.

    the ipconfig/all for my laptop reads as follows:

    C:\Documents and Settings\Jen>ipconfig/all

    It's probably some teensy thing I missed, but I do need internet on the laptop for school work (online classes).

    The connection is WEP enabled, and I have the correct key for it.

    Your ipconfig /all shows a partial IP configuration for the wireless and shows the ethernet disconnected. The disconnect could be a bad LAN port, bad router, bad cable, bad NIC or some messed up settings.

    Is any computer able to access the internet through the router? If not, try with a direct connection to the modem. Be sure to power cycle (unplug) the modem when switching devices.

    Please do the following on your laptop.

    (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.

    Try to connect via ethernet and wireless and show ...

    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.

    The computer I'm on right now is connected (wired) through the router, the IPCONFIG/ALL for this one is:

    And I'd already reset WINSOCK and TCP/IP just before running ipconfig for the last entry. I really hope it's not the router, and kind of doubt that it is as we have another laptop running on the wireless connection at this time. I think I'm leaning towards a LAN port issue, but you guys are the experts, y'know : )

    To summarize, the router seems to be just fine, as other computers are accessing the internet both wired and wireless.

    The stack and WINSOCK repairs were run on the JenZ laptop before the ipconfig /all that shows ethernet disconnected and a partial-only configuration for the wireless. If this summary is completely correct it makes me think that there is some serious damage on that laptop.

    You can easily test for LAN port and cable--simply connect the laptop using the known good port and cable that beth-174bbf6565 is now on. If the ethernet LED on the laptop does not light or the ipconfig /all still shows Media Disconnected for it, it's dead.

    Before thinking about spending any money, I suggest you do the repairs again and then post another ipconfig /all per post #2.

    Well, when I plugged the Ethernet into the laptop, that seemed to work fine. The IPCONFIG/all is identical to the desktop's information that I posted before:

    I see a wireless connection there, is that to your router, or have you connected to someone else's network?

    The repairs seem to have brought the ethernet back to life.

    The wireless is still strange, with a partial IP configuration.

    Suggest that you reset the router to factory default settings; use Device Manager to uninstall the wireless adapter, and then let it reinstall; try the wireless connection again and show another ipconfig /all.

    I had done the repairs before even posting here, so they really had no (visible) effect on whatever is wrong with the laptop's connection. The last post was the IPCONFIG/ALL I ran while the laptop was connected to the router via the ethernet cable that was originally connected to the desktop, which I am using now. It seems to be the only way that a Local Area Connection shows up at all, as Network Connections tells me --logically-- that a network cable is unplugged when I do not have the ethernet cable attached.

    At the time of the last IPCONFIG/ALL posting my wireless LAN was still apparently connected to the router, though completely useless as it still does not connect wirelessly via the router to the internet.

    I'd really like the reset to be a last resort, so if there are any other tests I can run or settings I can check on, please let me know. My mother uses the DSL line as a part of a transcriptioning service, and avoiding downtime for her would be appreciated.

    Also, running the IPCONFIG/ALL now reads the same as the very first post. Just thought I should at least try to leave a real update.

    To try to determine whether this is a router problem (my top suspect at the moment) or an adapter problem try to connect the computer to another wireless network and try to connect another computer to the wireless network in question.
