The three main ways to get internet service

You connect to the internet through an Internet Service Provider (ISP) — a company that runs the cables, fiber, or wireless network that reaches your home. The type of connection available to you depends on what infrastructure exists in your area, not on what you choose. Most homes have one to three options: cable, fiber, or DSL. Some rural areas only have satellite or fixed wireless. You cannot order a fiber connection if fiber lines do not run to your house, so the first step is always finding out what your address can actually get.

Each connection type uses different physical infrastructure to deliver data to your home. Cable runs through the same lines that carry television signals. Fiber uses thin glass strands that transmit light. DSL uses existing telephone lines. Satellite beams data from orbit. Fixed wireless uses radio towers. The speed, reliability, and cost of each type vary widely, and so does availability — a connection type common in one neighborhood may not exist three blocks away.

Key Takeaways

  • Your address determines which connection types are physically available to you; you cannot order a type that has no infrastructure in your area.
  • Cable, fiber, and DSL are the most common options in populated areas, while satellite and fixed wireless serve rural locations.
  • You need three things to go online: a physical connection from an ISP, a modem (which converts that signal), and a router (which broadcasts it wirelessly to your devices).
  • Speed is measured in megabits per second (Mbps), and what you need depends on how many people use the connection and what they do online.
  • Contracts, data caps, and equipment fees vary by provider and plan, so comparing what each ISP offers in your area takes time but saves money.

Finding out what connection types serve your address

Start by visiting BroadbandMap.fcc.gov, the Federal Communications Commission's official tool. Enter your street address and it will show you which ISPs offer service there and what type of connection each one uses. This is the most reliable way to see your actual options — not what a company's website says is available in your state, but what is genuinely wired to your specific address.

You can also check individual ISP websites directly. Major cable providers include Comcast (Xfinity), Charter (Spectrum), and Cox. Major fiber providers vary by region — Verizon Fios, AT&T Fiber, and Google Fiber operate in some areas but not others. For DSL, check AT&T, Verizon, or CenturyLink depending on your region. If you live in a rural area, search for satellite providers like Starlink or Viasat, or fixed wireless providers like T-Mobile Home Internet. The FCC map will tell you which ones actually serve your address.

Understanding modems, routers, and what you actually need to buy

A modem is the device that converts the signal from your ISP's infrastructure into data your devices can use. It connects directly to the cable, fiber line, or telephone line coming into your home. A router is a separate device that takes the signal from the modem and broadcasts it wirelessly (and sometimes with wired connections) to your phone, laptop, tablet, and other devices. Some ISPs provide a combined modem-router unit, but they are usually separate devices.

When you sign up for service, your ISP will either mail you a modem or send a technician to install one. Many ISPs charge a monthly equipment fee — typically $10 to $15 — for renting their modem. You can often buy your own modem instead and avoid this fee, but it must be compatible with your ISP and connection type. Ask your ISP which modems they support before you buy. The router is almost always your responsibility to buy or rent separately, though some ISPs bundle a router into their equipment fee.

If you rent equipment from your ISP, you return it when you cancel service. If you buy your own, you own it and can take it with you if you move to a new ISP that supports it.

What speed you actually need

Internet speed is measured in megabits per second (Mbps). The higher the number, the faster data moves to and from your home. What you need depends on how many people are using the connection at the same time and what they are doing. Streaming video uses much more speed than browsing text. Video calls use more than email. Multiple people doing these things simultaneously uses more than one person doing one thing.

A rough guide: 25 Mbps supports one person streaming video or a few people browsing and emailing. 50 to 100 Mbps supports a household where multiple people are streaming, video calling, or working from home at the same time. 200 Mbps or higher is for households with many simultaneous users or people who upload large files regularly. These are not hard rules — your actual experience depends on the specific service, the time of day, and network congestion in your area.

When comparing plans, pay attention to both download speed (what you use most) and upload speed (what you need for video calls and file uploads). ISPs advertise download speed prominently but upload speed is often much lower. If you work from home and video call frequently, upload speed matters more than the headline number suggests.

Comparing plans and understanding what you will pay

Once you know which ISPs serve your address and what speeds they offer, compare the total monthly cost, not just the advertised price. Many ISPs offer a promotional rate for the first year, then raise the price significantly. Ask what the regular rate is after the promotion ends. Some plans include equipment rental in the advertised price; others add it on top. Some have data caps (a monthly limit on how much data you can use before overage fees kick in); others have unlimited data.

Write down for each plan: the advertised speed, the promotional price and how long it lasts, the regular price after promotion, the equipment fee (if separate), whether there is a data cap and what it is, any contract length or early termination fee, and the installation cost. This takes time but makes the real cost visible. A plan that looks cheap at $40 per month might cost $65 after the promotion ends, plus $15 for equipment, plus overage fees if you hit a data cap.

Some areas have only one or two ISPs, which means less room to negotiate. In competitive areas, you can sometimes call and ask for a better rate, especially if you mention a competitor's offer. Many ISPs will match or beat a competitor's price to keep your business.

Setting up your connection when service arrives

If you ordered a modem to be mailed, it will arrive with instructions. If your ISP is sending a technician, they will install the modem and test the connection. Either way, the modem connects to the line coming into your home (cable, fiber, or phone line) and to power. It takes a few minutes to power on and connect to your ISP's network — you will see lights on the modem indicating it is working.

Next, connect your router to the modem using an ethernet cable (a thin cable with connectors on both ends). Plug the router into power. It will take another minute or two to start up. Once it is on, you should see a wireless network name (called an SSID) appear when you search for available networks on your phone or laptop. The default network name and password are usually printed on a sticker on the router. Connect your devices to this network using the password.

If you are not sure the connection is working, open a web browser and try to load a website. If it loads, you are online. If it does not, restart the modem (unplug it for 30 seconds, then plug it back in) and wait a few minutes for it to reconnect. If you still cannot connect, contact your ISP's support line — they can check whether the service is active on your account and troubleshoot from their end.

What to do if your address has no wired options

If cable, fiber, and DSL are not available at your address, your options are satellite or fixed wireless. Satellite internet (Starlink, Viasat, HughesNet) works by sending data to and from satellites orbiting Earth. It works almost anywhere but has higher latency — a slight delay between when you send a request and when you get a response — which can make video calls feel sluggish and online games unplayable. It also has data caps on most plans and can be affected by heavy rain or snow.

Fixed wireless (T-Mobile Home Internet, Verizon 5G Home) uses radio towers on the ground, similar to cell phone service. It has lower latency than satellite and no data caps on most plans, but it is only available in areas where the provider has built out their network. Check the provider's coverage map for your address. Both satellite and fixed wireless are more expensive than cable or fiber in most cases, but they may be your only option in rural areas.

Frequently Asked Questions

Can I use my cell phone as a modem to get internet at home?

Yes, through a feature called tethering. Your phone can share its cellular data with your laptop or other devices. However, this uses your phone's data plan, which usually has a monthly limit and overage charges. It is useful for occasional use or backup, but not practical as your primary home internet if you stream video or have multiple people online.

Do I have to sign a contract with an ISP?

It depends on the provider and plan. Some ISPs offer month-to-month service with no contract. Others require a 12-month or 24-month contract and charge an early termination fee if you cancel before it ends. Check the contract terms before you sign up. Month-to-month plans often cost more per month but give you flexibility to switch providers.

What is the difference between download speed and upload speed?

Download speed is how fast data comes to your home — what you use when you stream video, load websites, or download files. Upload speed is how fast data goes from your home to the internet — what you use when you video call, send large emails, or upload photos. Most ISPs offer much higher download speeds than upload speeds. If you work from home and video call frequently, ask about upload speed specifically.

Why is my internet slower than the speed I am paying for?

Several things can slow it down: too many devices connected at once, distance from the router, interference from other wireless networks, network congestion during peak hours, or a problem with your modem or router. Try restarting your modem and router, moving closer to the router, or disconnecting devices you are not using. If the problem persists, contact your ISP — they can check whether the service is delivering the promised speed on their end.

Can I switch ISPs if I am unhappy with my current one?

Yes, but check whether you have an active contract with an early termination fee. If you do, you may owe that fee when you cancel. If you are month-to-month or your contract has ended, you can switch freely. Before you switch, confirm that the new ISP serves your address and that you understand their contract terms and equipment fees.
