    A couple of days ago my laptop's network adapters stopped working. They were fine and then suddenly I was no longer able to connect to the internet wirelessly or through my LAN. I know it's not the modem because the computer I'm on and my xbox both connect fine.

    I had a couple of spyware and viruses on the computer and I removed them with AVG. Initially I still had internet access then out of nowhere I started getting "unidentified network" and "limited connectivity". I've tried everything: automatically get new IP settings, reset adapter, uninstall and reinstall the drivers, i reset winsock, ipv4 and ipv6. I've even tried disabling ipv6 all to no avail.

    If anyone can help it will be greatly appreciated. I'm running Windows Vista Home Premium Service Pack 1 on a Compaq-Presario CQ50 Notebook PC.

    Basically if your getting "unidentified network" and "limited connectivity",this means that your laptop is not communicating with the modem or router. I assume that your modem has a wireles capability, if trying to connect wirelessly can you see the wireless network name of your modem?

    Open Network and Sharing Center via the wireless or Lan icon on the system tray, on the left pane of the window click manage wireless networks. Once the window open clear out all the networks that you can see, delete them from the list. After deleting them try again to connect wirelessly.

    i just swapped my desktops ethernet to the laptop and same problem.

    not sure if this is connected but right before the internet started messing up i deleted something called mywebsearch off the computer. i'm pretty sure it was spyware, malware, or something related.

    Try booting to safe mode with network and check if you can access the internet.

    TCP/IP stack repair options for use with Vista or Windows 7.

    Start, All Programs\Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt.

    In the command prompt window that opens, type type the following commands, each followed by the Enter key:

    Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

    Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log

    Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log

    Reboot the machine.



    Let's see this with the cable connected to the router.

    Hold the Windows key and press R, then type CMD then press Enter to open a command prompt:

    In the command prompt window that opens, type type the following command:

    Note that there is a space before the /ALL, but there is NOT a space after the / in the following command.

    IPCONFIG /ALL

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

    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.

    Connect with a wired connection that you KNOW is a working cable and port on the router and post another IPCONFIG /ALL

    I did. I unplugged the ethernet cable from the desktop I'm on right now, plugged it into the laptop, did IPCONFIG /ALL, saved the results, plugged it back into the desktop then posted the results on here.

    It looks like your laptop is not communicating with the modem, as you can see on the result that you posted the Default Gateway is blank were in it should be showing the IP Address of the modem or router. Also, your LAN card and wireless card are all getting 169.254.109.19 and 169.254.163.84 IP Addresses respectively. This IP Addresses are invalid and it is automatically being assigned by the operating system.

    Are you directly connected to the modem or thru a router?
