    Hi guys! Need input. HP Pavilion A6313W.....Windows Vista Home Premium....Arris modem....Linksys WRT310N Router....

    Everything ran fine until a couple of days ago when we had lightning storms and somehow my router got fried. Everything else was plugged into a surge protector and fine (yeah, stupid me!). I've since replaced the router with the exact model but am having connection problems with only my computer. I have another computer and an xbox wired to the router and they have no problems. My computer will only have internet for maybe 30 sec before i get the red x and the "you are not connected" note. When this happens and try to run diagnostic it says the network cable is not plugged in, knowing full well it is. At one point i had a note saying some file was corrupt but couldn't duplicate it again. I've tried rebooting the modem, router, and the computer several times.....no luck. As a last resort i even did a system recovery, no luck there.:mad:

    Any ideas? I'd greatly appreciate it!

    thanks!!!

    Most likely a defective NIC, cable or router LAN port. You can mix and match with the other computer to check the cable and router port.

    In case the driver is corrupted use Device Manager to uninstall the ethernet; reboot and let Windows discover the adapter and reinstall the driver.

    Can also try Safe Mode with Networking to help determine whether this is a hardware or software problem.

    Also try the following repairs ...

    (From a JohnWill post)

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

    Start, 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.
