If you cannot connect to the Internet, your Internet Protocol or TCP/IP may have been corrupted, and you may have to reset TCP/IP. TCP/IP is one of the core components required by your Windows computer to connect successfully to the Internet. In such a situation, even though you may be physically connected to the Internet, packets do not get transferred over the network and you may see the “The page cannot be displayed” message when you try to connect to a URL.
If your Windows 10/8/7 computer is unable to connect to the Internet, you may want to reset TCP/IP. Do remember to create a system restore point first. If you are not able to browse the internet, but able to ping other IP address, then resetting TCP/IP works.
Reset TCP/IP using NetShell utility
You can reset Reset Internet Protocol to its default state using the NetShell or netsh utility.
To do so, open an elevated command prompt, type the following and hit Enter:
netsh int ip reset
This will generate a log file:
netsh int ip reset resettcpip.txt
If you are using IPv4, type the following and hit Enter:
netsh int ipv4 reset
If you use IPv6, type the following and hit Enter:
netsh int ipv6 reset
When you run the command, TCP/IP is reset and the actions taken are recorded in the log file, created in the current directory, named here as resettcpip.txt.
When you run this reset command, it overwrites the following registry keys, both of which are used by TCP/IP:
This has the same effect as removing and reinstalling TCP/IP.
