The Three Main Ways to Connect

You can connect your computer to the internet using an ethernet cable, Wi-Fi, or a mobile hotspot. Ethernet is the fastest and most stable option — you plug a cable directly from your modem or router into your computer. Wi-Fi is wireless and works from anywhere in your home, but can be slower and less reliable. A mobile hotspot uses your phone's data plan to create a wireless network your computer can join.

Which method you choose depends on what equipment you have, how fast you need the connection, and whether you move your computer around. Most homes use Wi-Fi because it works with laptops and lets you move freely. Desktops often use ethernet because they stay in one place and benefit from the faster speed.

Key Takeaways

  • Ethernet cables plugged directly into your modem or router give you the fastest, most stable internet connection.
  • Wi-Fi requires a wireless router and works from anywhere in your home, but may be slower than ethernet.
  • You can use your phone as a mobile hotspot to connect your computer to the internet if you do not have a modem or router.
  • Check your computer's network settings to see which connection method is active and troubleshoot if the connection drops.
  • Restart your modem and router by unplugging them for 30 seconds if your internet stops working.

Connecting with an Ethernet Cable

An ethernet cable is a thin cord with plastic connectors on both ends. One end plugs into your modem or router, and the other plugs into the ethernet port on your computer — usually on the back of a desktop or the side of a laptop. The port looks like a slightly oversized phone jack. Once you plug the cable in, your computer should recognize the connection within a few seconds.

On Windows, look at the bottom right corner of your screen near the clock. You should see a network icon that shows a connected ethernet symbol. On a Mac, click the Wi-Fi icon in the top right corner — if ethernet is connected, it will show "Ethernet" with a green dot next to it. If the connection does not appear after 30 seconds, unplug the cable, wait 10 seconds, and plug it back in.

Ethernet cables come in different lengths, from 3 feet to 100 feet or more. If your computer is far from your modem or router, you may need to buy a longer cable. They cost between $5 and $20 depending on length and quality. Make sure the cable is rated Cat5e or higher — anything older may not work with modern internet speeds.

Connecting to Wi-Fi

To use Wi-Fi, you need a wireless router connected to your modem. The router broadcasts a wireless signal that your computer can detect. On Windows, click the network icon in the bottom right corner of your screen. You will see a list of available Wi-Fi networks. Find the name of your router — it is usually printed on a sticker on the router itself — and click it.

Windows will ask you for a password. This is the Wi-Fi password, also printed on the router sticker. Type it exactly as shown, including capital letters and numbers. Once you enter the correct password, your computer will connect and remember that network. The next time you are near that router, your computer will connect automatically.

On a Mac, click the Wi-Fi icon in the top right corner. You will see a list of available networks. Click the name of your router, then enter the password when prompted. The process is the same — your Mac will remember the network and reconnect automatically in the future.

If you do not see your router's name in the list, the router may be too far away, turned off, or broadcasting on a frequency your computer does not support. Move closer to the router and try again. If the router is off, press the power button on the back. If you still cannot see it after moving closer, restart the router by unplugging it for 30 seconds, then plugging it back in.

Using Your Phone as a Mobile Hotspot

If you do not have a modem or router, you can use your phone's data plan to create a wireless hotspot that your computer can connect to. This uses your phone's cellular data, so make sure your phone plan includes data and has enough remaining for the month. Streaming video or downloading large files will use data quickly.

On an iPhone, go to Settings, then Cellular, then Personal Hotspot. Turn on the toggle switch. Your phone will display a Wi-Fi password — write it down. On your computer, find your phone's name in the Wi-Fi network list, click it, and enter the password your phone displayed.

On an Android phone, go to Settings, then Network and Internet, then Hotspot and Tethering. Tap Wi-Fi Hotspot and turn it on. Your phone will show a network name and password. On your computer, find that network name in your Wi-Fi list, click it, and enter the password.

Keep your phone and computer close together for the best connection. The farther apart they are, the weaker the signal. Also remember that using your phone as a hotspot drains its battery faster than normal — plug your phone in if you plan to use it for more than an hour.

Checking Your Connection Status

On Windows, right-click the network icon in the bottom right corner and select "Open Network and Internet settings." You will see which connection is active — either ethernet or Wi-Fi — and how strong the signal is. If you are connected to Wi-Fi, you will see the network name and signal strength as a series of bars.

On a Mac, click the Wi-Fi icon in the top right corner. If you are connected, you will see a checkmark next to the network name and the signal strength shown as bars. Click "Open Network Preferences" to see more details about your connection, including your IP address and the speed of your connection.

If your connection drops or becomes very slow, the first step is always to restart your modem and router. Unplug both devices from power, wait 30 seconds, then plug them back in. Wait two minutes for them to fully restart before trying to connect again. This fixes most temporary connection problems.

Troubleshooting Common Connection Problems

If your computer will not connect to Wi-Fi, first make sure you are entering the correct password. Passwords are case-sensitive, meaning capital letters are different from lowercase letters. If you are not sure of the password, look at the sticker on your router — it is usually printed there. If the password on the sticker does not work, you may have changed it at some point. Check any emails from your internet provider that mention your Wi-Fi password.

If ethernet is plugged in but your computer does not recognize it, try a different ethernet cable if you have one. The cable itself may be damaged. Also check that the cable is fully inserted into both the port on your computer and the port on your modem or router — it should click into place.

If your internet is very slow, move your computer closer to the router if you are using Wi-Fi. Walls, metal objects, and other electronics can block the signal. If you are using ethernet, the problem is usually with your internet service provider, not your computer — contact them to report slow speeds.

If you are connected but cannot reach any websites, restart your modem and router as described above. If that does not work, restart your computer. If the problem continues, your internet service may be down in your area — check your provider's website or call their customer service number.

Frequently Asked Questions

Is ethernet faster than Wi-Fi?

Yes, ethernet is typically faster and more stable than Wi-Fi. Ethernet can deliver speeds up to 1,000 megabits per second or higher, while Wi-Fi usually maxes out around 300 to 600 megabits per second depending on your router. For everyday tasks like email and web browsing, both are fast enough, but ethernet is better for downloading large files or streaming video.

Can I use both ethernet and Wi-Fi at the same time?

Your computer can be connected to both, but it will only use one at a time. Windows and Mac both prefer ethernet when both are available, so if you plug in an ethernet cable while connected to Wi-Fi, your computer will switch to ethernet automatically. You do not need to do anything — the switch happens in the background.

Why does my Wi-Fi password not work even though I typed it correctly?

Make sure you are looking at the Wi-Fi password, not the router admin password — they are different and printed separately on the sticker. Also check that Caps Lock is not on, since passwords are case-sensitive. If you have changed your Wi-Fi password since setting up the router, the new password is the one you need to use, not the one on the sticker.

How far away can my computer be from the router and still connect?

Most routers have a range of 100 to 150 feet in open space, but walls and obstacles reduce this significantly. Each wall can cut the range in half. If your computer is more than 30 feet away or separated by multiple walls, you may have a weak signal. Moving the router to a higher, more central location in your home usually improves range.

What should I do if my internet keeps disconnecting?

Restart your modem and router by unplugging both for 30 seconds, then plugging them back in. If disconnections continue, move your computer closer to the router if using Wi-Fi, or check that your ethernet cable is fully inserted if using a cable. If the problem persists, contact your internet service provider — the issue may be with their service rather than your equipment.
