The three main ways to get internet on your device

You connect to the internet through one of three routes: a wired connection plugged directly into your device, a wireless connection to a router in your home, or a mobile connection through a phone plan. Most people use wireless at home and mobile on the go, but which one works for you depends on what device you have, what your internet service provider offers, and where you are when you need to connect.

Each method has a different setup process and different reasons you might choose it. A wired connection is the most stable but requires a cable. Wireless is convenient but needs a router and a password. Mobile is portable but uses data from your phone plan. Understanding what each one does helps you pick the right one for what you are trying to do right now.

Key Takeaways

  • Wired connections plug an ethernet cable directly from your modem or router into your device and are the most stable option.
  • Wireless connections use a router to broadcast a signal you join with a network name and password, and work from anywhere in range.
  • Mobile hotspot connections share your phone's data plan with other devices and work anywhere your phone has signal.
  • Your internet service provider gives you a modem; you may need to buy or rent a separate router to use wireless.
  • Connection problems usually come from forgetting the password, being out of range, or the device not turning on — check those first.

Connecting with a wired ethernet cable

A wired connection is the fastest and most reliable way to connect. You need an ethernet cable (a thin cable with a plastic connector on each end that looks like a thick phone cord), a modem or router with an ethernet port, and a device with an ethernet port or an adapter. Plug one end into the port on your modem or router labeled "Ethernet" or "LAN" and the other end into your device. Your device should recognize the connection within a few seconds and start working immediately — you do not need to enter a password.

Most laptops made before 2015 have an ethernet port built in. Newer laptops, tablets, and phones do not. If your device does not have a port, you can buy a USB adapter (usually $10 to $25) that lets you plug in an ethernet cable. Desktop computers almost always have an ethernet port on the back of the tower. If you are not sure whether your device has one, look for a small rectangular port about the size of a phone jack, usually on the side or back.

Wired connections are best for gaming, video calls, or downloading large files because they are faster and do not slow down if other people are using the internet nearby. The downside is you have to stay in one place — the cable only reaches as far as it is long, usually 3 to 100 feet depending on the cable you buy.

Connecting wirelessly through your home router

Wireless connections let you use the internet from anywhere in your home without a cable. Your internet service provider gives you a modem, which is a box that connects to the wall outlet and receives the internet signal. To use wireless, you also need a router, which is a separate box that broadcasts the signal as wifi. Some modems have a router built in, but most do not — if you are not sure, look at your device: if you can see a list of wireless networks when you search for wifi, you already have a router.

To connect wirelessly, find the network name (also called SSID) and password. These are usually printed on a sticker on the bottom or back of your router. On your device, go to Settings, then Wifi or Network Settings, and look for your network name in the list. Tap or click it, enter the password exactly as it appears (uppercase and lowercase letters matter), and wait a few seconds. Once it connects, you should see a wifi symbol on your screen and be able to open a web browser.

If you cannot find your network name in the list, the router may be off or too far away. Move closer to the router and try again. If the password does not work, check that you typed it correctly — common mistakes are confusing the letter O with the number 0, or the letter l with the number 1. If you still cannot connect, restart the router by unplugging it for 30 seconds, plugging it back in, and waiting two minutes for it to fully start up.

Using your phone as a mobile hotspot

A mobile hotspot turns your phone into a portable router by sharing your phone's internet connection with other devices like tablets or laptops. This uses data from your phone plan, so check your plan to see how much data you have each month — video streaming and large downloads use data quickly. Most phone plans include some hotspot data, but some plans limit it or charge extra.

To turn on your hotspot, go to Settings on your phone, then look for "Hotspot," "Mobile Hotspot," "Tethering," or "Personal Hotspot" depending on whether you have an Android or iPhone. Turn it on and note the network name and password shown on the screen. On your other device, search for wifi networks, find your phone's hotspot name, and enter the password. Your device should connect within a few seconds.

Mobile hotspots are useful when you are away from home, at a coffee shop, or traveling. The downside is that your phone battery drains faster when the hotspot is on, and the connection is usually slower than home wifi. If multiple devices are connected to your hotspot at once, the speed slows down further. Turn off the hotspot when you are not using it to save battery.

What to do if your device will not connect

The most common reason a device will not connect is a wrong password. Check that you typed it exactly as shown on the router sticker, including capital letters and numbers. If the password has special characters like @ or &, make sure you entered those too. Try typing it again slowly, one character at a time.

The second most common reason is that the device is out of range. Wifi signals weaken the farther you are from the router, especially through walls and metal objects. Move closer to the router and try connecting again. If you are in a different room, move to the same room as the router temporarily to test whether distance is the problem.

Third, check that the router is actually on. Look for a power light on the front or back of the router — it should be lit up. If it is not, plug in the power cable or check that the outlet has power by plugging in a lamp. If the router is on but you still cannot see your network name, restart it by unplugging it for 30 seconds, waiting for the lights to come back on, and trying again.

If none of those work, restart your device. Turn it off completely, wait 10 seconds, and turn it back on. Then try connecting again. If you are still stuck, contact your internet service provider — they can check whether your modem is working and may be able to restart it remotely.

Understanding data usage and speed

Wired connections are fastest because the cable carries the signal directly without interference. Wireless is slower because the signal travels through the air and can be blocked by walls and other devices. Mobile hotspots are slowest because they rely on cell towers, which are farther away and shared with many other people.

Data usage matters mainly for mobile hotspots and phone plans with data limits. Wired and home wireless connections use unlimited data (unless your internet plan itself has a limit, which is rare). Streaming video uses the most data — about 1 gigabyte per hour for standard quality and 3 gigabytes per hour for high quality. Browsing websites, email, and social media use much less. If you have a limited data plan, turn off your hotspot when you are not actively using it and avoid streaming video when possible.

Speed also depends on your internet plan. Your service provider sells different speeds — common ones are 25, 100, or 300 megabits per second. Faster speeds cost more but let you download files quicker and stream video without buffering. If your connection feels slow, you can check your actual speed by searching "internet speed test" in a web browser and running a free test. If your speed is much lower than what you are paying for, contact your service provider.

When to use each connection type

Use a wired connection when you need the fastest, most stable connection — for online gaming, video calls, or downloading large files. Use it if you are in one place for a long time and do not mind having a cable. Use wireless when you want to move around your home or office without a cable, or when you have multiple devices that need to connect at once. Use a mobile hotspot when you are away from home and need internet on a device that does not have its own phone plan, or when your home internet is down temporarily.

Many people use all three at different times. You might use wired for work at a desk, wireless for browsing on the couch, and mobile hotspot on a tablet while traveling. There is no single "best" way — it depends on what you are doing and where you are doing it.

Frequently Asked Questions

Do I need a password for a wired connection?

No. Wired connections do not need a password because the cable is plugged directly into your device. Only wireless and mobile hotspot connections require a password.

Can I use both wired and wireless at the same time?

Yes, but your device will use the wired connection and ignore the wireless one. If you unplug the cable, it will automatically switch to wireless. This is useful if you want to move around without losing internet — just unplug when you leave your desk.

What is the difference between a modem and a router?

A modem connects to your internet service provider and receives the internet signal. A router takes that signal and broadcasts it as wireless. Your service provider provides the modem; you may need to buy a router separately, or your modem may have one built in.

Why is my wireless connection slower than wired?

Wireless signals travel through the air and can be blocked or weakened by walls, metal, and other devices. Wired connections use a cable, so the signal travels directly without interference. Moving closer to the router usually improves wireless speed.

Can I connect to someone else's wifi?

Yes, if they give you the password. Search for their network name in your wifi list, select it, and enter the password they provide. You will use their internet connection and their data, so ask permission first.
