These commands reset TCP/IP, Windows Socket, and Windows Firewall. Programs like firewalls, antivirus applications, VPN clients, and various malware can cause Internet connection problems. When there are Internet connection problems in Windows 7, Vista, or XP, make sure there are no firewalls installed other than the Windows Firewall. If other firewalls are in use, consider uninstalling them and re-enable the Windows Firewall. If problems persist, try the following commands. To automate this process, download and run networkquickfix.bat.

Otherwise, only the first command will work. Restart the computer. Summary If the commands are typed in properly but errors occur, Windows networking may be heavily damaged. In addition, if these commands do not return errors, yet do not fix the Internet connection after the computer has been restarted, consider further troubleshooting: Power-cycle any external networking devices, i.e. routers, cable modems, DSL gateways, etc. Check Device Manager for any problems with Network adapters, i.e. if they are disabled or if drivers are not properly installed.
