    I just changed my router setup, and now all the other computers are working fine, and the router is working fine, but Windows 7 (my main2 server), is losing network connectivity randomly. It is wired into the router. To fix it I have to disable the adapter, enable it, and reboot my machine. Then it stays connected until it's next outage.

    Install or re-install the latest ethernet driver.

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

    TCP/IP stack repair options for use with Vista through 10.

    Start - All Programs - Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt. [For Windows 8 thru 10: <Windows Logo> + x - Command Prompt(Admin)]

    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 after all three commands; no need to boot after the 1st and 2nd.
