    I have a Dell Studio 1555 laptop with Windows 7 Home Premium that I've owned for just over two years.

    Last night, after a couple of hours using the internet, the connection stopped. The wireless router still had an 'Excellent' signal, but it also said I had no internet access. All of the other wireless devices in my house connect to the internet perfectly, including when right next to the laptop.

    I've tried disabling the firewall and resetting the computer a few times, but nothing seems to pick up the internet access. The troubleshooting guide tells me that it is a problem with the wireless modem, but quite obviously that isn't true.

    I haven't installed anything on the computer for several months, and I have already ran a full virus check. Can anyone help me? Thank you in advance!

    Can you successfully connect by ethernet?

    Please attach a screen shot of the Networks page (don't collapse the Radar, Connection or Signal History) of the Xirrus Wi-Fi Inspector. If you need help with that see TSG Posting a Screenshot. FWIW to take screen shots with Windows 7 or Vista I prefer to use the built-in Snipping Tool.

    Also show ...

    Open a (black) Command Prompt window:
    Hold the Windows logo key and press r; in the Run box type cmd and click on OK.

    Type the following command:

    IPCONFIG /ALL

    [Note that there is no space between the slash and 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.

    Ethernet connection does not work, which does seem to suggest an internal problem.

    What firewall or security suite do, or did you ever, have on the system?

    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.
