How to connect a desktop computer to Wi-Fi wirelessly: all the working methods

Desktop computers are traditionally associated with wired internet—a long Ethernet cable from the router to the system unit seems like an inevitable compromise for performance. But what if the router is in another room and you don't want to run a cable through the entire apartment? Or what if you rent a place where drilling holes in walls for network installations is prohibited?

Fortunately, wireless connection of a PC to Wi-Fi It's even possible without a built-in module—and you don't have to buy a new system unit to do this. In this article, we'll look at all current methodsFrom budget USB adapters to unconventional life hacks using a smartphone or a second device, you'll discover which method is best for you based on your budget, technical skills, and speed requirements.

Important: If your computer was built after 2020, there is a good chance that the motherboard already has a built-in Wi-Fi module (especially in models from ASUS, Gigabyte or MSI (With the prefix "WiFi" in the name). Check this before purchasing additional equipment—instructions are in the section below.

1. Checking the built-in Wi-Fi module: is it necessary to buy an adapter?

Before spending money on external devices, make sure your PC is not equipped with built-in wireless moduleThis is relevant for:

• 🖥️ Ready-made PCs from HP, Dell, Lenovo (series Pavilion, Inspiron, IdeaCentre)
• 🔧 Self-assembled computers on mid-range/high-end motherboards (e.g. ASUS ROG Strix, Gigabyte AORUS)
• 💻 All-in-one PCs (almost all models have Wi-Fi out of the box)

To check if a module is available:

1. Click Win + R, enter devmgmt.msc and press Enter.
2. IN Device Manager expand the tab Network adapters.
3. Look for devices with names like Wireless, Wi-Fi, 802.11ac or AX200/AX210 (popular models from Intel).

If the module is there but does not work:

• 🔄 Restart your computer and check if Wi-Fi is enabled on the motherboard (sometimes there is a separate button or switch on the back panel).
• 🔧 Update the driver through the official website of the motherboard manufacturer (do not use driver packs like Driver Booster - they often install outdated versions).
• ⚡ Check if the adapter is disabled in BIOS/UEFI (section Advanced → Onboard Devices Configuration).
