The three ways to get internet into your home

Internet reaches your home through one of three physical paths: a cable line (usually shared with TV), a phone line (DSL), or a wireless signal from a tower (broadband or 5G home internet). Each one plugs into a device called a modem, which converts the signal into data your devices can use. The modem then connects to a router, which broadcasts that data wirelessly to your phone, laptop, and other devices — or you can plug devices directly into the router with an ethernet cable for a faster, more stable connection.

Which path reaches your address depends on what infrastructure your neighborhood has. A cable company runs cables down your street. A phone company runs phone lines. A wireless carrier builds towers in the area. You cannot choose the infrastructure — it is already there or it is not — but you can choose which company provides service over that infrastructure, and you can choose whether to rent or buy your modem and router.

The process of getting connected is the same regardless of which path you use: contact a provider, schedule installation or self-install, set up your modem and router, and connect your devices. The main differences are speed, cost, and availability in your area.

Key Takeaways

  • Internet reaches your home through cable, phone line, or wireless signal, and you need both a modem (converts the signal) and a router (broadcasts it to your devices) to use it.
  • Your address determines which types of internet are available — you cannot choose the infrastructure, but you can choose the provider and whether to rent or buy equipment.
  • Most providers offer self-installation with a modem and router shipped to your home, or a technician can install it for you, usually within a few days.
  • Once connected, you log into your router's settings to change the Wi-Fi password and network name, and then connect each device by selecting the network and entering that password.

Finding out what internet types are available at your address

Before you contact any provider, you need to know which types of internet actually reach your location. The fastest way is to visit the website of the major providers in your area and enter your address into their coverage checker. For cable, check Comcast, Charter, or Cox (depending on your region). For phone-line internet, check AT&T, Verizon, or CenturyLink. For wireless home internet, check Verizon, T-Mobile, or Starry.

The coverage checker will tell you whether that provider serves your address and what speeds they offer there. Write down the results from each provider you check — this list becomes your options. If only one type of internet is available (for example, only cable), you will have fewer choices of provider but the process is the same. If nothing comes up for your address, contact your city or county planning department to ask what infrastructure exists in your neighborhood — sometimes new providers are expanding into an area.

Once you know what is available, compare the monthly cost, the speed (measured in Mbps), and whether there is a contract or early termination fee. Speed matters most if you have multiple people streaming video or working from home at the same time; otherwise, most providers' standard plans work fine for everyday use.

Ordering internet and choosing equipment

Contact the provider you want to use and tell them you want to set up service at your address. They will ask for your name, address, phone number, and billing information. At this point they will also ask whether you want to rent or buy your modem and router.

Renting is simpler upfront — the provider ships you equipment or a technician installs it, and you pay a small monthly fee (usually $10 to $15). If the equipment breaks, the provider replaces it. Buying means you pay $100 to $300 upfront for a modem and router, but you own them and have no monthly equipment fee. If you plan to keep the internet for more than two years, buying usually costs less overall. If you buy, ask the provider which modem and router models work with their service — not all equipment works with all providers.

The provider will also ask whether you want them to install it (a technician comes to your home, usually within three to seven days) or whether you want to self-install (they ship the equipment and you set it up yourself). Self-installation is faster and free; technician installation costs $50 to $100 but is useful if you are not comfortable with the setup steps or if your home has unusual wiring.

Setting up your modem and router

When your equipment arrives or is installed, you will have a modem (a box with lights on the front) and a router (usually a smaller box or a combined modem-router unit). Plug the modem into the wall outlet and into the cable, phone line, or antenna that brings internet into your home. Wait two to three minutes for the lights to stop blinking — this means the modem has connected to the provider's network.

Plug the router into power and into the modem using an ethernet cable (a thin cable with clips on each end). Wait another two to three minutes. The router's lights will show when it is ready. At this point, your home network is broadcasting, and you should see its name (called the SSID) when you look for Wi-Fi networks on your phone or laptop.

Open a web browser and go to 192.168.1.1 or 192.168.0.1 — one of these addresses will load your router's settings page. Log in using the username and password printed on the router (usually "admin" and "admin" or a code on a sticker). Once you are logged in, find the Wi-Fi settings and change the network name and password to something you will remember. This is the name and password you will give to anyone who wants to connect a device to your internet.

Connecting your devices to the network

On your phone, laptop, tablet, or other device, open the Wi-Fi settings and look for the network name you just created. Select it and enter the password you set. The device will connect and you should see an internet connection symbol (usually a Wi-Fi icon) appear on the screen.

Repeat this process for each device you want to connect. Once a device has connected once, it will usually reconnect automatically when it is in range of your network. If a device will not connect, the most common causes are a typo in the password, the device being too far from the router, or the device's Wi-Fi being turned off. Check the password first, then move closer to the router, then check that Wi-Fi is enabled on the device.

If you have a device that does not have Wi-Fi (like an older desktop computer or a printer), you can plug it directly into the router using an ethernet cable. This connection is actually faster and more stable than Wi-Fi, so it is worth doing if the device will stay in one place.

Troubleshooting a connection that is not working

If your modem has no lights or the lights are red, unplug it, wait 30 seconds, and plug it back in. This restart fixes most connection problems. Wait three minutes for the lights to stabilize. If the lights are still off or red after the restart, the modem may not be receiving a signal from the provider — contact your provider's support line and tell them the modem lights are not coming on.

If the modem lights are on but you cannot see your Wi-Fi network on your devices, restart the router the same way: unplug it, wait 30 seconds, plug it back in, and wait three minutes. If the network still does not appear, check that the router is plugged into power and into the modem with an ethernet cable. If both are plugged in correctly and the network still does not appear after a restart, the router may need to be reset — hold the small reset button on the back for 10 seconds, then set it up again from the beginning.

If you can see the network but cannot connect, or if you connect but have no internet, restart both the modem and router (modem first, then router, waiting three minutes between each). If that does not work, check that you are entering the correct password — passwords are case-sensitive, meaning capital letters matter. If you are still stuck, contact your provider's support line with the modem model number (printed on the modem) and describe what the lights are doing.

Understanding your bill and what happens next

Your first bill will show the monthly service charge, any equipment rental fee, and any installation fee. Promotional rates (a lower price for the first year) are common — check your contract to see when the price increases. Some providers also charge a one-time set up fee or require a contract with an early termination fee if you cancel before a certain date. Read the fine print before you sign up so there are no surprises.

Once you are connected, your internet will work continuously unless there is an outage in your area (which your provider will announce on their website or app) or unless you do not pay your bill. Most providers give you a grace period of 10 to 30 days after the due date before they disconnect service. If you move, contact your provider at least two weeks before you leave so they can disconnect service and you do not keep paying for it.

Frequently Asked Questions

Do I need both a modem and a router, or can I use just one?

You need both. The modem converts the signal from your provider into data. The router takes that data and broadcasts it wirelessly to your devices. Some providers offer a combined unit that does both jobs in one box, but it is still two functions. If you only have a modem with no router, your devices cannot connect wirelessly.

What is the difference between Wi-Fi and internet?

Internet is the data coming into your home from the provider. Wi-Fi is the wireless signal your router broadcasts so your devices can access that internet without being plugged in with a cable. You can have internet without Wi-Fi (by plugging devices directly into the router with ethernet cables), but you cannot have Wi-Fi without internet.

Can I use the same modem and router if I switch providers?

Sometimes. If you bought your own equipment, check the provider's website to see if your modem model is on their approved list — different providers use different technology and not all modems work with all providers. If you rented from your old provider, you must return that equipment and either rent from the new provider or buy your own.

Why do I need to restart my modem and router so often?

Restarting clears the device's memory and forces it to reconnect to the provider's network, which fixes most temporary glitches. You should not need to restart more than once a month under normal conditions. If you are restarting weekly, contact your provider — it usually means the modem is having trouble staying connected.

Is ethernet cable faster than Wi-Fi?

Yes. Ethernet cables give you the full speed your provider is sending. Wi-Fi is slower because the signal has to travel through the air and can be blocked by walls and distance. If you are doing something that needs maximum speed (large file uploads, video calls, online gaming), plug in with ethernet if you can.
