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!

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:

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

install malwarebytes free version or other software to remove the malware from your computer run the software to clean the malware on the computer - restart computer after finish cleaning the malware.

I have the same problem with build 10049. No way to set up any static IP.

However I used the following solution: Manually assigned IP address in your router DHCP server for the MAC address of your computer network adapter.

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? –  Arjan Apr 18 at 9:55
