Ping Transport Failed with Error 1231

Posted on Updated on

Recently I was helping a friend with her laptop which suddenly stopped connecting to the Internet, despite that the wireless networking could see and successfully connect to wireless hotspots. In further troubleshooting, I noticed that the correct IP address range (192.168.0.x) was not handed out by the router’s DNS. Furthermore, when attempting to ping the router’s gateway ( with “Ping Transport Failed, Error 1231“. Digging through the Internet on this error, I found the possible solution buried deep within a couple Microsoft forum threads. I’m posting it here so that if it should ever occur again, hopefully the solution is quicker to find!

  1. Open a command prompt with Run As Administrator
  2. Run “netsh winsock reset”
  3. Restart Windows

Now the system is back in business!
