There are several things that can give this problem;

No internet service - check with another device and find a non-cached page such as bbc.co.uk/news. Do this on both devices.  If nothing happens look at the roouter and see if you have a service. It might be a telephone line or exchange fault.

If it's just a problem on one device then you maty need to reset the stack, also known as a winsock error. Just follow these guide;ines. There are other methods of doing this but we find this the fastest;

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.

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 command prompt, type the following and hit Enter:

netsh int ip reset resettcpip.txt

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.
