What is ISP ?
An Internet service provider (ISP, also called Internet access provider, or IAP) is a company that offers its customers access to the Internet. The ISP connects to its customers using a data transmission technology appropriate for delivering Internet Protocol datagrams, such as dial-up, DSL, cable modem, wireless or dedicated high-speed interconnects.

ISP actually depends on your internet provider. I think your router might be not configured according to the service provider you are using... I think you must call for the assistance to your internet service provider for it.

You need an Internet service provider (ISP) and some hardware to connect to the Internet:

• ISP. An ISP provides access to the Internet. You sign up for an account with an ISP just as you do for telephone service or utilities.
  
  
• Hardware. For a broadband connection such as Digital Subscriber Line (DSL) or cable, you need a DSL or cable modem. This is usually included as part of the start-up hardware from your ISP when you sign up for a broadband account. For a dial-up connection, you need a dial-up modem. Many computers come with this type of modem already installed.
