This morning I got no internet connection from my desktop pc, there’s no changes in my PC network configuration or my office LAN. I try to PING my office router ( and got this message :

Ping Transmit Failed General Failure

So like usual I searching the solution and find this working :

  • Flush DNS cache from command prompt : ipconfig /flushdns
  • Disable and then Enable my Ethernet device from “Control Panel/Network and Internet/Network Sharing Center/Change Adapter Settings”

Hope it also working for you 🙂
