ISP and Wi-Fi Guide

For students and everyday users, reliable internet access is essential—whether you're submitting homework, researching, or enjoying online entertainment. This guide explains two key parts of getting online: understanding your Internet Service Provider (ISP) and connecting your Windows 11 computer to a wireless network.

What Is an ISP and Why Do You Need One?

To access the internet, you need three main things: a device (computer, laptop, or tablet), a web browser (such as Microsoft Edge), and an Internet Service Provider (ISP). You likely already have the first two—the ISP is the final link that connects you to the internet.

An ISP is a company that provides your internet connection for a monthly fee. Once your device connects to your ISP’s network, Windows automatically detects the internet and allows you to browse websites.

What an ISP Does

  • Monthly Cost: ISPs typically charge between $30 and $100 per month, depending on speed and location.
  • Types of Internet Connections:
    • Dial-up modem – very slow but still used in some rural areas.
    • Broadband – includes DSL, ISDN, and cable internet.
    • Fiber optic cable – extremely fast, offered by select providers.
  • Shared Connections: One ISP subscription can power all your home devices, including laptops, phones, and smart TVs through wired or wireless networks.
  • Free Options: Many public businesses—coffee shops, airports, hotels—offer free Wi-Fi that you can use without paying an ISP.
Analogy: Your ISP is like an electricity company. Your computer is the appliance, your browser is the switch, and the ISP is the utility provider that supplies the connection.

How to Connect Wirelessly to the Internet

Windows 11 constantly searches for nearby wireless signals. If you've connected to a network before, it will reconnect automatically. If not, you’ll need to manually select and join a network.

Step-by-Step: Connecting to a Wi-Fi Network

  1. Click the Wi-Fi Icon: Located near the clock on your taskbar.
    • If connected, you’ll see the Wi-Fi symbol.
    • If not connected, you may see a “No Internet” icon.
  2. Open Network Options: A menu will appear. Click the right arrow next to the Wi-Fi icon.
  3. Select a Network: Windows lists all available Wi-Fi networks by signal strength.
  4. Click Connect: Choose your network and click the Connect button.
    • Enable Connect Automatically if you want Windows to remember it.
  5. Enter the Password: If the network is secure, enter the Wi-Fi password.
    • At home, this is your router’s password.
    • In public, ask staff for the access code.
  6. Choose Network Type:
    • Home or work: Choose “Yes, turn on sharing…” (Private network).
    • Public places: Choose “No, don’t turn on sharing…” (Public network).
Tip: Always choose “Public Network” in public spaces to prevent others from accessing your files.

What Your Wi-Fi Icon Tells You

The Wi-Fi icon shows how strong your connection is—the more bars, the stronger the signal.

5 Frequently Asked Questions

What is an ISP and why is it necessary?

An ISP is a company that provides your internet connection. Without an ISP, your device cannot access websites or online services.

Can I use Wi-Fi without paying for an ISP?

Yes—public places like coffee shops, bookstores, and airports often offer free Wi-Fi. For home use, however, you typically need your own ISP subscription.

What happens if I choose “Yes, turn on sharing” on a public network?

Your device becomes discoverable, which is unsafe on public Wi-Fi. Other users might gain access to your files. Always choose “No” when on public networks.

What types of internet connections are most common today?

Common options include broadband (DSL, ISDN, cable), fiber optic internet (very fast), and dial-up in remote areas.

I can’t connect to Wi-Fi—what should I check?

Move closer to the router, confirm the password, or use Windows Network Troubleshooter. In hotels, sitting near a window sometimes improves weak signals.
