Connection of internet through mobile

Wireless routers with built-in switches are everywhere. Although there are differences between the routers, they have largely the same features. This guide provides a summary of the common aspects of the routers currently on the market. Reading your router manual is still necessary to know exactly what features your router has and where they are located, but reading this will give you an idea of what to expect before diving into the manual.

What is a router?

A router is any device that acts as a gateway between 2 or more separate networks. In our case, that means that the local network is connected to the Internet, and vice versa. The router ignores traffic local traffic or traffic it is not configured to handle, but when Internet access is attempted from within the local network, it springs into action. With NAT (Network Address Translation), the router shares the Internet connection to all the computers connected to the local network. The router keeps track of the originating local computer and manages the connection with the outside Internet server. If a computer on the Internet attempts a connection with the router or to a local computer past the router, the router denies the connection unless the router was specially configured to allow that connection.
