Call your ISP (Internet Service Provider)…
Answer #2
Click the Start menu button on the Windows taskbar.
Click Run... on this menu.
If the computer is holding a current IP address, type 'cmd' (without the quotes) in the text box that appears. A command prompt window appears on the screen.
Type 'ipconfig' (without the quotes) to view the status of the computer's IP address(es).
If the computer is holding a current IP address, type 'ipconfig /release' to let go of the address.
Type 'ipconfig /renew' to obtain a new IP address (whether or not the computer is holding a current address).
