Super User is a question and answer site for computer enthusiasts and power users. It's 100% free, no registration required.

In the Control Panel\Network and Internet\Network Connections, I have a Wireless Network Connection. When I right-click on it, a properties dialog opens. Now, I need to change the IP address for TCP/IPv4. But the Properties button is disabled.

https://dl.dropboxusercontent.com/spa/ymse6uo5hhtvqry/tcp-properties-disabled.png

I tried following commands:

  • netsh int ip reset
  • netsh winsock reset
  • netsh interface IPV4 uninstall
  • netsh interface IPV4 install

but did not help.

My issue resembles this question, but I m not sure it is due to DHCP configuration of my ISP provider. Because the internet is working on another computer.

Thanks in advance!

I assume you've tried restarting your computer and router, but try

"netsh ipv4 reset", "netsh ipv6 reset", "ipconfig /release", "ipconfig /renew", and "ipconfig /flushdns"

THEN restart your computer.

If that doesn't work, then refer to this thread: http://answers.microsoft.com/en-us/windows/forum/windows_7-networking/tcpipv4-properties-button-disabled/347899fa-b60a-40a3-ad2c-78ef5e0dca37

As it suggests a malware infestation of the "c:\windows\system32\drivers\tcpip.sys" file
