how to enable 'Properties' button of TCP/IPv4 in Network connections in Windows 7

Question

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.

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!

Solution

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

This sounds like a nice workaround, but reading the other answers I wonder if this doesn't hide the cause, which apparently might be that IPv6 is on and supported, or worse: malware? So, did you read the link from dadda7860's answer?

I assume this answer is about Windows 10. In that case, it doesn’t apply here. Also, this “workaround” (if you even call it that) is simply pointless. There are more (important) settings hidden in that menu.
