Internet and Wi-Fi are vital parts of many modern households. However, you’ll no doubt notice many differences between their capabilities and features. The internet stores information on servers all over the world and helps transmit the data you need to your devices. Wi-Fi allows wireless transmission of internet data from routers and modems to computers and back again.

This comprehensive guide will help you learn more about Wi-Fi, the internet, types of internet service, how to set up internet and Wi-Fi, internet service providers (ISPs), and answers to some frequently asked questions.

What is the internet?

The internet is a massive network of computers and servers that communicate with each other globally. People use it to view websites, stream content, play games, and more. They can connect with anyone who also has internet access, and large amounts of information are available online.

The thousands of smaller networks on the internet communicate with each other and send packets through Transmission Control Protocol or Internet Protocol (TCP/IP). These rules allow different websites to communicate with each other and transfer information even when they use varied programming languages. Most packets transferred through TCP/IP have 1,000 to 1,500 bytes of information, and the packet transfer rate has increased over time through technological advancements. A faster speed can make building complex websites and web applications easier, and it allows for nearly instant communication worldwide.

There are many types of internet service. Speeds usually refer to the maximum download rate, and upload speeds are often slower. In most cases, the variation isn’t noticeable for a high-speed plan, but you may notice it if you have a lower-speed plan.


Digital subscriber line (DSL) service is a phone-based internet service that largely replaced dial-up in the early 1990s. It uses a dual-channel phone line. One channel transfers internet data, and the other allows simultaneous phone and internet usage. Standard DSL speeds range from 50 to 300Mbps, and DSL’s performance is much more reliable than dial-up. Today, people who live in remote areas without access to other internet options are most likely to use DSL.


Cable internet is usually offered by companies that also sell cable TV service and utilizes the same lines that deliver standard cable television. Offering reliable connections and fast speeds, cable internet is popular with avid gamers and households with multiple internet users.


Many people in remote areas use satellite internet service out of necessity because other options aren’t available. However, satellite internet infrastructure is more expensive to maintain than other types of internet service. Most satellite internet plans are more expensive, particularly those that allow users access from anywhere through a dedicated satellite card.

Home-mounted satellite dishes are common, less expensive forms of satellite service. Satellite internet service can transfer data at speeds up to 100Mbps, and it’s useful for households with multiple users and gamers who don’t have access to a stronger connection.

Fiber optic

Fiber optic internet service uses fiber optic cables capable of transferring data using infrared light. It’s the most advanced, high-bandwidth form of internet service currently available, and it can reach data transfer rates of up to 5Gbps or 5000Mbps. Fiber optic service is mostly available in larger cities, but ISPs are always working to expand their infrastructure to service other locations.

Fiber optic networks are immune to damage through electromagnetic interference, making fiber optic internet service the preferred type for survivalists. People with very high data transfer requirements, like scientists and technical workers who use complex modeling software, also favor fiber optic internet service.


With most cell phone providers, mobile or wireless internet service is available with a cell phone service plan. People sometimes call this type of cell phone-based internet service mobile data. Using a smartphone or other device, people can access the internet from their homes or on the go, although access may be limited if reception is poor.

What is Wi-Fi?

Wi-Fi is an internet technology that allows wireless transmission of internet data packets from routers and modems to computers and servers and back again. It uses radio waves that move out and down from the Wi-Fi source, making it capable of sending or receiving data to or from any Wi-Fi-capable device within range.

While many of us connect devices, such as laptops and printers, over Wi-Fi today, more people are adding internet-ready smart home devices to their homes. Today, you can connect smart thermostats, smart refrigerators, digital assistants like Amazon Alexa, and other devices to the internet using Wi-Fi. You can use your smartphone or computer to communicate with these smart devices even when you’re not at home.

There are three types of Wi-Fi commonly used in homes: Type G, Type N, and Type AC.

Type G

Type G is the oldest type of Wi-Fi technology still in use today. For households without many members and devices, or with low bandwidth requirements, it can be very cost-effective compared to newer versions.

Type N

Type N or Wi-Fi 4 supports 802.11n-2009 signals, sometimes called 802.11n. It’s a wireless networking standard that uses multiple antennas to improve data transfer rates. Type N Wi-Fi has standardized support for multiple inputs, multiple outputs, security, frame aggregation, and other features. Also, it can work in the 2.4GHz radio frequency bands. Many gamers prefer this type of Wi-Fi for its impressive data transfer capabilities, and it’s also popular with homes with four or more internet users. It also has better short-range signal fidelity than other types of Wi-Fi.

Type AC

Type AC Wi-Fi, also called high-throughput Wi-Fi, runs at 5GHz, a higher radio bandwidth than Type G or Type N. Type AC is faster than Type G, and it’s comparable to Type N in many ways. Its primary advantage is its range. The best Type AC Wi-Fi systems can broadcast a strong signal up to 1000 feet, making it ideal for families who own large properties with multiple buildings.

How to set up internet service

If you want to create a Wi-Fi network in your home, you’ll need to establish internet service. To get started, begin by finding out more about the ISPs near you. You’ll need to weigh several factors, such as the number of people in your household, the number of devices you plan to connect at one time, and the types of tasks you plan to perform. Equipped with that information, you can compare plans from ISPs to understand which one offers the speed you need at the price you want to pay.

Many ISPs offer plans for residential customers within the US. Prices and system capabilities can vary widely from location to location, so you should always do your due diligence and find local options. Getting familiar with some of the top-name ISPs is an excellent place to start.
