    I purchased this laptop for school and it was working perfectly fine. The network connection was great and everything. Today it decided not to connect to the internet, yet it is still connected to my network, but recognizes it as undefined. Instead of having the normal bars it has a yellow exlamation mark. I have contacted my ISP and my router is working fine. I'm on a different computer and it is working fine as well, so there's something wrong with my computer. I have contacted a representative and they said they could not help me either.

    But surely someone here will be able to help hopefully.

    I have tried everything I know to fix it. I cannot connect even if I'm using the ethernet cable.

    The computer is an Acer laptop and I have Windows 7.

    Could you go to the start menu and run the command "cmd", then when the black window opens up, type in: ipconfig /all (there's a space before the '/', but not after it) then press return. A whole bunch of stuff will scroll. Could you cut/paste that info into a response here?

    What, if any, non-Windows firewall or security suite is on the machine?

    (From a JohnWill post)

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

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

    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.
