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 (192.168.0.1) 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!
- Open a command prompt with Run As Administrator
- Run “netsh winsock reset”
- Restart Windows
Now the system is back in business!
