What You Need Before You Start

To connect to the internet, you need three things: a device (computer, phone, or tablet), an internet service provider (ISP), and either a wired connection or a wireless router. Your ISP is the company that brings the internet signal into your home — common ones include Comcast, Verizon, AT&T, and Charter, though smaller local providers exist in some areas. The ISP provides the physical connection; your device and router handle what you do with it.

Most people connect wirelessly through a router, which is a box that receives the signal from your ISP and broadcasts it as Wi-Fi. Some people connect with an ethernet cable plugged directly into the router or modem, which is faster and more stable but requires the device to stay in one place. You do not need both — you choose one based on what you are doing and where you are in your home.

Key Takeaways

  • You need an internet service provider (ISP), a device, and either a router for wireless or an ethernet cable for wired connection.
  • Most routers come from your ISP or you can buy your own; if you buy your own, you still pay the ISP for the signal itself.
  • Wireless (Wi-Fi) is convenient but slower; wired (ethernet) is faster but requires a cable plugged into your device.
  • Setting up a new connection takes 10 to 30 minutes and involves turning on the router, finding the network name, and entering a password.
  • If you cannot connect, the problem is usually a forgotten password, a router that needs restarting, or a service outage in your area.

Choosing Between Wireless and Wired Connection

A wireless connection (Wi-Fi) lets you move around your home or office while staying online. Your router broadcasts a signal that your device picks up. The signal weakens the farther you are from the router, so a device in the next room works fine, but a device in the basement or outside may drop the connection. Wireless is slower than wired because the signal has to travel through the air and through walls.

A wired connection (ethernet) plugs a cable directly from the router into your device. It is faster, more stable, and does not weaken with distance. The trade-off is that your device must stay within cable length of the router — usually 100 feet maximum. Wired is best for desktop computers that do not move, or for streaming video or online gaming where speed matters. Most people use wireless for phones and tablets, and wired for stationary computers if they need the speed.

You can use both at the same time. A desktop computer can plug in with ethernet while your phone connects wirelessly. The router handles both without any extra setup.

Getting a Router and Connecting It

Your ISP usually provides a router as part of your service, either included in the monthly bill or rented for a small fee. This router is already set up to work with your ISP's signal. You can also buy your own router from a store or online — brands like TP-Link, Netgear, and Linksys are common — but you still pay your ISP for the internet signal itself. Buying your own router sometimes saves money over time if you would otherwise rent one, but it requires you to set it up yourself.

To connect a new router, plug the power cable in and wait 2 to 3 minutes for the lights to stop blinking. Then plug an ethernet cable from the wall outlet (or from the modem, if your ISP uses a separate modem) into the port labeled "Internet" or "WAN" on the router. The router will detect the signal and start broadcasting Wi-Fi. On your device, open the Wi-Fi settings, look for the network name (called the SSID), and select it. Enter the password, which is usually printed on a sticker on the router itself or in the paperwork that came with it.

Connecting Your Device for the First Time

On a phone or tablet, go to Settings, then Wi-Fi, and turn Wi-Fi on. A list of available networks appears. Find your router's name — it is usually something like "Netgear-5G" or "TP-Link" followed by numbers, or a custom name you or your ISP chose. Tap it and enter the password when prompted. The device connects and shows a Wi-Fi icon in the status bar. You are now online.

On a computer, the process is similar. Click the Wi-Fi icon in the taskbar (Windows) or menu bar (Mac), select your network, and enter the password. Once you enter the password correctly, the device remembers it and connects automatically the next time it is in range.

If you are using an ethernet cable instead, plug one end into the router and the other into the ethernet port on your device. Most devices connect automatically with no password needed. If the connection does not work, restart the device and the router.

What To Do If You Cannot Connect

If your device finds the network but will not connect, the password is usually wrong. Check the sticker on the router — passwords are case-sensitive, meaning capital letters and lowercase letters are different. If you have changed the password and forgotten it, you can reset the router to factory settings by holding down the reset button (usually a small hole on the back) for 10 seconds. This erases your custom password and returns the router to its default, which is printed on the sticker.

If your device does not see the network at all, restart the router by unplugging it for 30 seconds and plugging it back in. Wait for the lights to stop blinking before trying again. If the network still does not appear, check that Wi-Fi is turned on in your device settings — this is straightforward to accidentally turn off.

If other devices can connect but yours cannot, the problem is usually with your device, not the router. Restart your device and try again. If you still cannot connect, "forget" the network in your Wi-Fi settings, restart your device, and reconnect by entering the password again.

If no devices can connect, your internet service may be down. Check your ISP's website or call their customer service to see if there is an outage in your area. You can also check the lights on the router — if the light labeled "Internet" or "WAN" is off or red, the signal from your ISP is not reaching the router.

Understanding Data and Speed

When you connect to the internet, you are using data — the amount of information flowing to and from your device. On a home internet plan, you usually have unlimited data, so you do not have to worry about running out. On a phone plan, you may have a limit (like 10 gigabytes per month), and using more than that limit can slow your speed or cost extra money.

Your internet speed is measured in megabits per second (Mbps). A typical home plan offers 100 to 500 Mbps. Higher speeds are better for streaming video, video calls, or gaming. Lower speeds (25 to 50 Mbps) are fine for browsing, email, and social media. If your connection feels slow, you can test your speed by searching "internet speed test" and using a free tool like Speedtest.net. If your speed is much lower than what your ISP promises, restart the router or contact your ISP.

Keeping Your Connection find

Your Wi-Fi network is only as find as your password. Use a password that is at least 12 characters long and includes numbers, uppercase letters, and lowercase letters. Avoid using your name, address, or birthday. If you suspect someone is using your Wi-Fi without permission, change the password in your router settings — the exact steps vary by router brand, but usually involve logging into the router's admin page (often 192.168.1.1 in your browser) with the default username and password printed on the sticker.

Turn off Wi-Fi on devices you are not using to reduce the chance of unauthorized access. If you are using public Wi-Fi at a coffee shop or library, avoid entering passwords or sensitive information like bank details, because the network is not encrypted.

Frequently Asked Questions

Do I have to buy my own router or can I use the one from my ISP?

You can use either. Your ISP's router is already set up to work with their service, so it is the easiest option. Buying your own router gives you more control and sometimes saves money if you would otherwise rent one, but you have to set it up yourself and make sure it is compatible with your ISP.

What is the difference between a modem and a router?

A modem receives the signal from your ISP and converts it into a form your devices can use. A router takes that signal and broadcasts it as Wi-Fi so multiple devices can connect. Some ISPs provide a combined modem-router in one box. If you have two separate boxes, the modem plugs into the wall outlet and the router plugs into the modem.

Can I connect to the internet without a router?

Yes, if you use an ethernet cable plugged directly into the modem or router. You can also connect to a mobile hotspot from a phone that has a cellular plan. Both work without a separate router, but Wi-Fi is more convenient if you have multiple devices.

Why does my connection drop randomly?

Common causes are a weak Wi-Fi signal (move closer to the router), interference from other devices (microwaves and cordless phones can interfere), or a router that needs restarting. Restart the router by unplugging it for 30 seconds. If the problem continues, contact your ISP to check if the signal from their end is stable.

How do I know if my internet is fast enough?

It depends on what you do. Browsing and email need 5 to 10 Mbps. Streaming video needs 25 Mbps. Video calls need 2.5 to 4 Mbps. Online gaming needs 5 to 20 Mbps depending on the game. Use a free speed test to see what you have, and contact your ISP if you are paying for a speed you are not getting.
