Issue

Windows 10 Pro PC cannot get IP address from Draytek Vigor router DHCP server (over Wi-Fi). Other devices on the network were not affected so it wasn’t a DHCP server issue. The PC could connect with no issues with a static IP, so Wi-Fi connection also didn’t seem to be an issue.

Resolution

The issue was resolved by resetting WINSOCK and TCP/IP stack.

• Open elevated command prompt and run following commands:
  • netsh winsock reset catalog
  • netsh int ipv4 reset reset.log
  • netsh int ipv6 reset reset.log
• Reboot computer
