    All right I have been searching on this subject for a while and I am hoping I can find help here. So far I have baffled my instructors on this subject at school and I am hoping you can get me on the right track. My laptop does not connect to the internet at all, via Ethernet or wireless but can connect wirelessly through my local network and I can see my other computers and printer. I have tried reconfiguring the DNS and reconfiguring the IP address. I also took the suggestion of removing the gateway and that didn't help. So what else am I missing? I haven't wiped the computer yet to reinstall the OS as I had done that two months prior to the computer not connecting to the internet. I have all ready checked the switch on the front of the computer and it is set to on. All my other computers have no problem connecting to the modem. The computer keeps telling me that its the modem not the computer but since it doesn't connect via the Ethernet I am sure its the computer, Help?:(

    The computer in question runs Vista OS, here are my specs:

    What firewall or security suite is, or ever was, on the system?

    TCP/IP stack repair options for use with Vista or 7 or 8.

    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.

    The firewall is the standard vista windows firewall and we down loaded Microsoft security essentials when we reloaded the OS and the laptop was able to connect for at least two months without a problem and then one day it stopped working.

    Okay I inputted the commands and still no connection. :(

    You said that you 'can connect wirelessly through my local network and I can see my other computers and printer" but the ipconfig /all showed no connection. If you can still connect to the network please show an ipconfig /all for that.

    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 8 or 7 or Vista I prefer to use the built-in Snipping Tool.
