How to Connect to the Internet via Wi-Fi: 5 Proven Methods

Connecting a personal computer to the Internet via Wi-Fi It seems like a simple task—until you encounter a missing built-in adapter, outdated drivers, or signal blind spots. Unlike laptops, where the module Wireless While wireless is usually integrated, desktop PCs often require additional hardware. This article will help you understand how to set up a wireless connection from scratch: from choosing an adapter to setting up a secure network.

We'll cover all current methods—from traditional router connections to using a smartphone as a hotspot. We'll pay special attention to common errors: why a PC can't see the network, how to update drivers without internet access, and what to do if the speed is lower than expected. The instructions are adapted for Windows 10/11, but the principles of working with adapters and routers are universal.

1. Checking the presence of a Wi-Fi adapter on your PC

Before attempting to connect to the network, make sure your computer is physically capable of receiving Wi-Fi signalIn 70% of cases, connection problems are due to the absence or malfunction of the adapter.

How to check:

• 🖥️ Visual inspection: On the back panel of the system unit, look for antennas or a port with the inscription Wi-Fi/WLANBuilt-in adapters are rare—usually they are external USB devices or PCI cards.
• 🔍 Device Manager: click Win + X → Select “Device Manager” → Expand the “Network Adapters” tab. Look for devices with names Wireless, Wi-Fi or 802.11 (For example, Intel Wi-Fi 6 AX200).
• 📋 System information: Type in Windows search "msinfo32» → Go to "Components" → "Network" → "Adapter." All network devices, including disabled ones, are displayed here.

If there are no wireless adapters in the list, then they are not physically present in the system. In this case, you will need purchase and install external or internal module. Please note: some motherboards (e.g. ASUS ROG Strix or MSI MEG) have a built-in Wi-Fi 6, but only in top models.

⚠️ Note: Older PCs (manufactured before 2015) may not support modern standards. Wi-Fi 5/6In this case, the adapter will see the network, but the speed will be limited. 150 Mbps (standard 802.11n).

2. Selecting and installing a Wi-Fi adapter

If your PC doesn't come with a wireless module, you'll need to purchase one. Let's figure out which adapter to choose and how to install it correctly.

Types of adapters

Optimal for most users USB adapter — it doesn't require disassembling your PC and is compatible with any system. If you need maximum speed (for example, for online gaming or 4K streaming), choose PCI-e card with support Wi-Fi 6 (standard 802.11ax).

Installing the adapter

The process depends on the type of device:

• 🔌 USB adapter: connect to a free port (preferably USB 3.0 for high speed). Drivers are usually installed automatically.
• 🛠️ PCI-e card:
  1. Turn off your PC and disconnect the power cable.
  2. Remove the system unit cover.
  3. Find a free slot PCI-e x1 on the motherboard.
  4. Install the card, secure it with a screw and connect the antennas.

⚠️ Attention: When installing PCI-e Avoid using adapter slots covered by the graphics card, as this will degrade the signal. Ideally, use the slot furthest from the GPU.

3. Connecting to Wi-Fi via a router

The most common method is connecting to a home network through a router. Let's look at the process step by step.

Step 1: Turn on Wi-Fi on your router

Make sure your wireless network is active:

• 📡 Check the indicators on the router - light Wi-Fi or WLAN must burn.
• 🔄 If there is no network, hold down the button WPS/Reset for 5 seconds (on some models, for example Keenetic, there is a separate button Wi-Fi).
• 🖥️ Go to the router's web interface (usually at 192.168.1.1 or 192.168.0.1) and check your wireless network settings.

Step 2: Connecting to Windows

Instructions for Windows 10/11:

1. Click on the network icon in the lower right corner (next to the clock).
2. From the list, select your network (for example, TP-Link_1234).
3. Enter your password and click "Connect".
4. If an error occurs, click "Troubleshoot" - the system will automatically check the drivers and settings.

Critical error: If the connection drops after a few seconds after entering the password, there may be a problem with the router's security settings. Try temporarily disabling MAC address filtering or changing the encryption type. WPA3 on WPA2-PSK.

What to do if Windows doesn't show networks?

1. Check if Airplane mode is enabled (Win + A → Network).
2. Update the adapter driver manually via Device Manager.
3. Run the command prompt as administrator and enter:


netsh winsock reset
netsh int ip reset

Afterwards, restart your PC.

4. Setting up a connection without a router (Ad-Hoc)

If you don't have a router, you can set up a direct connection between your PC and another device (such as a laptop or smartphone) in Wi-Fi mode. Ad-HocThis method is suitable for temporarily distributing the Internet or transferring files.

Creating a network on Windows

To do this:

1. Go to Settings → Network & Internet → Mobile Hotspot.
2. In the "Internet Sharing via" section, select Wi-Fi.
3. Click Edit and set the network name (SSID) and password (minimum 8 characters).
4. Enable the "Allow using my Internet connection" option.

Now other devices can connect to your PC as an access point. Limitations:

• ⚡ Maximum speed - up to 100 Mbps (depending on the adapter).
• 📱 You can connect up to 8 devices simultaneously.
• 🔋 Working in this mode increases the load on the processor.

⚠️ Attention: In mode Ad-Hoc the protection doesn't work WPA3 - Use a strong password to avoid unauthorized access.

5. Connection via smartphone (USB/Bluetooth/Wi-Fi)

A smartphone can become a temporary hotspot if there are no other options. Let's look at all the options:
