    I have no network connection. wired or wireless on my laptop.
    Device manager does not have any devices with red/yellow issues.

    The ethernet device Realtek PCIeGBE does not show in ipconfig, but shows in Device Manager fine
    Connection status says limited connection, IPv4 and IPv6 not connected

    ipconfig /all and ipconfig /renew yield the following:


    Copyright (c) 2006 Microsoft Corporation. All rights reserved.

    C:\Users\User>ipconfig /all

    Windows IP Configuration

    Host Name . . . . . . . . . . . . : Laptop

    IP Routing Enabled. . . . . . . . : No
    WINS Proxy Enabled. . . . . . . . : No

    DHCP Enabled. . . . . . . . . . . : No
    Autoconfiguration Enabled . . . . : Yes

    C:\Users\Drew>ipconfig /renew

    Windows IP Configuration

    The operation failed as no adapter is in the state permissible for
    this operation.


    Please lend your assistance, this happened first after a windows update, then rolled back updates to fix. Now it happened when I disabled windows Test Mode and I can't get it to resolve.
    UPDATE: Actually Java was updated, rolling back the update to see if fixed.

    If rolling back this update fixes it, my question would be why do all updates cause this problem?

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

    In the Command Prompt, type in the bold text, one command after the other, pressing Enter between each one of them:

    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 computer.

    Thanks for the reply, I tried those commands before, but tried them once more and restarted to no avail. All commands executed without error. I don't understand how the devices (ethernet NIC & WiFi device) are OK in device manager, but completely absent from ipconfig /all.

    There is one non-error possibility for that. Check in Network Connections. Are the connections there, and are they enabled? Right click on the connection and select 'Enable.' If they are already enabled then 'Disable" them and re-enable.

    Yes they were enabled of course. Resinstalled windows as no forums seem to have a solution for the issue. Something must have been corrutped in the TCP/IP and nothing was going to fix it. All better now.
