You can connect a laptop to the Internet in different ways: via an Ethernet cable, via a mobile phone (in this case, it is used as a modem), via a USB modem. The difference between them is that the modem is located in different devices.

Instructions
Internet connection via Ethernet cable. In order to configure a connection of this type, you need to go to the "Network Connections" folder and select "Local Area Connection".

Click on this icon twice and you will see that a window appears called "Local Area Connection - Properties". In the "General" tab, select the "Internet Protocol (TCP / IP)" line and click on the "Properties" button.

A window appears called "Properties: Internet Protocol (TCP / IP)". Here, check the box next to the "Obtain an IP address automatically" line, since the laptop has a dynamic IP (changing from session to session).

Save the settings, click the "OK" buttons and, going to the "Network Connections" folder, double-click your connection. The Internet provider asks you to enter your username and password in the window that appears. Enter your details. You are online.

Connecting a laptop to the Internet via a mobile phone. First, install all software and drivers for your phone. These programs come with your phone on floppy disks. They are usually called PC Studio.

Follow the steps to connect your phone to your computer.

In the menu of your program, select the menu responsible for connecting to the Internet. And start creating the connection.
Follow all the instructions in sequence, and you will create a connection. Now create an appropriate shortcut on your desktop and use your phone connection.
