Fix network and internet problems by resetting TCP/IP stack

Sometimes your computer’s TCP/IP settings can configure improperly or become damaged or corrupted. If you can’t connect to the internet and have tried all other resolutions to the problem, resetting your TCP/IP settings might help.

Transmission Control Protocol/Internet Protocol short TCP/IP, is a suite of communication protocols used to interconnect network devices on the internet or internal network.

Because TCP/IP settings are integral part of Windows, you can’t simply uninstall and then reinstall to reset everything without doing system restore. Instead, you’ll have to use a Windows component called NetShell utility to reset TCP/IP settings.

The instructions below require administrator access. If you are not the administrator, please contact the administrator for assistance before continuing.

To start command prompt as administrator search for CMD or command prompt and right click select run as administrator.

Try typing the following at a command prompt to fully reset the TCP/IP Stack. Type each command and press enter.

netsh winsock reset 

netsh int ip reset 

netsh interface ipv4 reset

netsh interface ipv6 reset 

netsh interface tcp reset

netsh int reset all
 
ipconfig /flushdns

nbtstat -R

nbtstat -RR

netsh interface tcp set global autotuninglevel=disabled

netsh advfirewall reset

If you don’t feel comfortable running commands above then you are better of using downloadable fixes provided by Microsoft or much more powerful free software listed below.
