How to Easily Connect a WiFi Modem to a Computer - For those of you who don't know how how to connect wifi modem to the computer, in this article we will provide detailed information below.

We can now use the Internet without having to rely on a tethered connection thanks to WiFi. WiFi can be used on various devices, including computers, because of this. How to connect WiFi to a computer can be done in a number of fairly basic steps.

Some computers have an internet connection using a wired Local Area Network (LAN). This implies that some of these computers cannot directly connect to WiFi. But don't worry, you can connect a WiFi modem on your computer in the following way.

How to Easily Connect a WiFi Modem to a Computer

We need a gadget that can record wifi signals so we can use wifi when connected to a computer. Many people are still not sure how to connect a wifi modem to a computer. So, what are the steps?

When there was no wifi like today present in various wifi areas (cafes, restaurants, bus stops, airports, etc.), before when you wanted to access the internet you had to use a LAN cable.

We can no longer install wifi in our homes without first registering for services from one of several internet providers such as Indihome, Biznet, MyRepublic, and others, each of which charges a monthly rental fee.

Definition of Modem on a Computer

Modulator demodulator or better known by the abbreviation modem is an electronic device that is used to connect devices such as computers, laptops, cell phones, or other devices to the internet.

Modems work by converting or modulating digital data from computer devices into analog signals. The analog signal is then sent through the telecommunications network.

When the analog signal arrives back at the computer device, the signal will be converted back or demodulated into digital data so that it can be read by the computer device. In this way, the modem allows your device to connect to the internet.

Important Things That Need to Be Prepared

  1. Wifi service from internet provider.
  2. ONT Modem (default from provider).
  3. Routers
  4. Wifi adapter
  5. LAN cable

The first thing you can do is buy a WiFi adapter (WiFi receiver) for your computer, because computers don't have adapters like laptops.

There are various designs for you to choose from, including USB Adapter and PCI (Peripheral Component Interconnect Adapter) versions. Despite its name, its function is the same: it receives signals sent by a modem or router.

  1. USB Adapter models
  2. PCI Adapter models
  3. ONT Modem from the provider

A modem is a hardware device used to connect to a service provider's network and access the internet.

It's common to rent a modem if you subscribe to wifi, but it may also be provided by your carrier if you buy the service.

For ONT itself, they usually already have a wifi transmitter, so when you install wifi, you don't need to buy a router again. Except when the modem doesn't have a wifi signal transmitter indirectly you have to buy a router."

Important Things That Need to Be Prepared

1. Routers

By using a router, you can divide your network into smaller networks, or connect one larger network.

There are quite a number of routers available, each of which serves a variety of purposes. The router here is optional, because in this scenario the ONT modem already provides a wifi signal.

2. WiFi Connectivity Diagram or Flow

The internet connection starts with the internet provider being plugged into the modem, then sent to the router, which finally connects to various components including a PC, phone, TV, etc.

The following image illustrates that the NBN connection lacks a wifi signal. As a result, a router will be required.

Modem Functions On Computers

The following are some of the modem's capabilities:

  1. One of the intermediary tools that connect computer devices to the internet network.
  2. As a digital-to-analog converter for two-way communication.
  3. To link devices in a network.
  4. To compress the data conveyed by the signal.
  5. Carry out modulation and demodulation procedures.

Types of Modems on Computers

There are several types of modems, including:

1. External Modems

A computer internet modem is made possible with the use of an external modem. Digital data from the computer is converted into analog data through signal conversion.

A computer will process the analog data received by the modem and convert it into a digital signal for further processing.

2. Internal modems

Internal Modem is a type of modem that is positioned inside where the incoming analog signal will be converted into a digital signal and given directly to the computer.

3. ISDN modems

Modem Integrated Service Digital Network (ISDN) (ISDN) In a digital network, voice, data, and images are all transmitted to one another over a telecommunications network and then combined.

This network enables end-to-end Digital connectivity to enable a wider diversity of services.

4. GSM modems

GSM modem is a type of modem that uses a cell phone as a channel for data transmission. In most cases, a GSM connection card is used to offer this kind of modem.

5. Analog Modem – Computer Modem

Analog Modem is a form of modem that functions as a device that converts analog impulses into digital signals.

Analog Modems

6. ADSL modems

Asymmetric Digital Subscribe Line, or ADSL, is a type of modem that allows you to access the internet and make analog modem calls simultaneously. Splitter or other connecting device is quite useful when using it.

The purpose of the Splitter is to reduce interference so that it can operate simultaneously, just like using the internet and being able to use a regular telephone. It is unlikely that these two have much in common.

7. Cable Modems

Cable Modem is a type of modem that is used to receive data directly from service providers such as cable TV.

8. Wireless Modems

Modems as seen on TV remote controls, which transmit data via radio waves or infrared rays, are known as “wireless modems”.

9. CDMA Modem – Modem on the computer

CDMA modem is a type of modem that uses CDMA 1x or CDMA 800 MHz frequency. For the latest CDMA modem types, the EVDO Rev-A frequency is similar to 3G.

How Modems Work on Computers

Initially, the digital signal frequency sent from the computer is converted into an analog signal first by the modem and then transmitted via telephone cable to be sent to another computer and vice versa when connecting the computer to the telephone cable to be used as the internet, the computer will send data.

After that, the digital data will be converted into analog data by the modem and sent over the telephone line (or other cable). When the data is addressed, the modem returns and converts it from analog to digital form.

This also happens when downloading data in analog form, so that it can be displayed, the modem converts it to digital. This is how the internet around the world can communicate with each other.

How Modems Work on Computers

Modem Components on a Computer

A network-attached device, a network interface card (NIC) serves as an intermediary for the computer. Connect the network cable to the NIC once the card is installed and you are ready to share files between computers.

1. Network Interface Card

This part is a digital signal amplifier. As the signal, the intensity of the received signal grows. Repeaters are also used as a link between various media as long as the access method is the same.

2. Repeaters

As a physical part of the computer or as a central network for cable combinations to reach very long distances.

3. HUB

This component enhances signal and manages data. The back of the HUB has holes or ports.


As the name implies, this component performs a joiner LAN network. It is possible to bridge networks using repeaters and HUBs but the difficulties that develop as a result of their use are best handled by switches.

5. Access Points

Its function is basically the same as a HUB which is used as a connecting medium via wifi.

6. Bridges

Modem components are customizable and also smart compared to repeaters. CSMA or CD, depending on the network interface, is used to transport the data.

7. Routers

Modem components such as routers are also included, and may be smarter than other modem components. The router's job is to transfer data that has separate network addresses.

Internal Modem Advantages and Disadvantages

Below are the advantages and disadvantages of an internal modem, namely:


The following are some of the advantages of an internal modem, including:

  1. Another way to save space.
  2. More affordable in terms of cost.
  3. Because it's built into the CPU, there's no need for an external adapter.
  4. This system feels more concise without a lot of cables running around that might look messy.


The following are some of the disadvantages of internal modems:

  1. No indication as seen on external modem. As a result, it is relatively difficult to check the state of the modem (although it can be done using software).
  2. Since it doesn't have its own voltage source, it must be powered by a CPU power supply.
  3. CPU enclosure temperature may be rising. The result of the internal modem circuitry getting too hot.
