How to Download and Set Up Wi-Fi on PC: A Complete Guide (2026)

Have you just bought a new computer or reinstalled Windows but don't know how to connect to Wi-Fi? Or has your desktop PC suddenly lost its wireless connection? This problem is familiar to many, according to research. J'son & PartnersOne in five PC users encounters difficulties setting up Wi-Fi for the first time. Unlike laptops, where Wi-Fi is built in by default, desktop computers often require additional steps: purchasing an adapter, installing drivers, or manually configuring network settings.

In this article we will look at All possible ways to connect a PC to Wi-Fi — from basic setup via the Control Panel to resolving complex errors like "No available connections" or "Limited access." You'll learn which adapter to choose for maximum speed, how to go wireless even on an older system unit, and what to do if Windows doesn't recognize your network. And for those who prefer visual instructions, we've prepared step-by-step screenshots and a hardware compatibility table.

1. Check hardware compatibility: Does your PC have Wi-Fi?

Before attempting to connect to a wireless network, make sure your computer is physically capable Receive a Wi-Fi signal. In 60% of cases, connection issues are caused by a missing or faulty adapter. Here's how to check for one:

• 🖥️ Laptops: Almost all models released after 2010 are equipped with a built-in Wi-Fi module. The exception is some gaming or budget models (for example, Dell Latitude series E5xx0 without optional module).
• 💻 Desktop PCs: 99% of the time, a Wi-Fi adapter isn't included out of the box. You need to purchase one separately (USB or PCIe). Popular models: TP-Link TL-WN823N, ASUS USB-AC56, Intel AX200 (for motherboards with a connector M.2 Key E).
• 🔧 Hybrid devices (For example, Microsoft Surface or Lenovo Yoga): usually have a built-in module, but it can be disabled in the BIOS.

To find out for sure if your PC has a Wi-Fi adapter:

1. Click Win + R, enter devmgmt.msc and press Enter.
2. IN Device Manager expand the tab Network adapters.
3. Look for devices with words Wireless, Wi-Fi, 802.11ac or 802.11ax (For example, Qualcomm Atheros QCA61x4A or Intel Wi-Fi 6 AX201).

Critical Information: Some motherboards (eg. ASUS ROG Strix or MSI MEG) have a built-in Wi-Fi module, but it may be disabled in the BIOS by default. Check the settings Advanced → Onboard Devices Configuration.

2. Choosing a Wi-Fi Adapter for a PC: USB vs. PCIe vs. M.2

If your computer doesn't support Wi-Fi out of the box, you'll need to buy an external or internal adapter. There are three types, each suited for different purposes:

For most users, the best choice would be USB Wi-Fi 5 (802.11ac) Adapter — it delivers speeds of up to 867 Mbps, is compatible with any PC, and starts at 1,000 rubles. If you need maximum speed for online gaming or 4K streaming, consider PCIe adapters with Wi-Fi 6E support (For example, ASUS PCE-AXE58BT), but they will require a free slot on the motherboard.

When purchasing, pay attention to Wi-Fi standard:

• 📶 802.11n (Wi-Fi 4) - up to 300 Mbps (outdated, not recommended).
• 📶 802.11ac (Wi-Fi 5) - up to 1300 Mbps (optimal for most tasks).
• 📶 802.11ax (Wi-Fi 6/6E) — up to 2400 Mbps (needed for high loads).

3. Installing drivers for the Wi-Fi adapter

Even if you have a physical Wi-Fi module, Windows won't be able to use it without the correct drivers. The system can automatically install basic drivers, but these are often unstable or don't support modern standards (such as Wi-Fi 6). Here's how to install the drivers manually:
