Check for other causes and solutions

Realize that the reason may not be with your computer, but may be an
issue with your Internet service provider (ISP) or with issues on the
network at your work. Therefore, for some of these solutions, you might
need help from your ISP, or, if your computer is part of a network at
work, you may have to ask your network administrator for help.
Contact your ISP service

first contact your ISP to see whether it is experiencing any problems.
If the ISP has problems, wait until the problems are resolved before
you continue to troubleshoot.
Check the hardware devices
you still cannot connect to the Internet after you have confirmation
that your ISP is not experiencing any problems, manually check the
hardware devices on your small office network or your home network for
problems. For example, if a hub, router, modem, or access point is
installed on your network, check that it is connected correctly, and
that it is turned on and functioning properly. The solution might be as
simple as turning on or restarting a hardware device, and then
restarting your computer. For more specific troubleshooting information
about the hardware devices that you are using, refer to the hardware
documentation for your devices.
