No Wi-Fi on PC: How to connect to the internet without a built-in adapter?

Have you just bought or built a new computer, turned it on, and discovered that there's not a single Wi-Fi hotspot in the network list? Or have you lost your ability to connect to the wireless internet after reinstalling Windows? The reason is simple: Your PC doesn't have built-in Wi-Fi (or it's disabled). But that's not a death sentence! Even without specialized equipment, you can get online—and we'll tell you how. 5 different ways, from the simplest to the more technical.

Many users mistakenly believe that they need to buy an internal network card to connect to Wi-Fi. In fact, 90% of problems can be solved using software or handy devices, which you already have on hand. In this article, you'll find step-by-step instructions for each method, a comparison table of solutions based on speed and cost, and answers to frequently asked questions. It doesn't matter whether you're working on a desktop PC running Windows 10/11 or on a laptop with a damaged adapter - there are options for everyone.

Before you resort to drastic measures (buying new equipment), check three key points:

1. Make sure that the problem is actually the lack of an adapter, and not the drivers or router settings.
2. Try connecting to the internet via cable Ethernet — perhaps Wi-Fi is simply not needed.
3. Consider how important mobility is to you: if your PC is kept in one place, a wired connection is often more reliable.

1. Checking the presence of a Wi-Fi adapter in the system

Before looking for workarounds, make sure that your computer is not actually equipped with a wireless module. Windows it's done in a couple of clicks:

Open device Manager:

• 🔹 Click Win + X and select the item device Manager.
• 🔹 Or enter the phrase in Windows search device Manager.

In the window that opens, find the section Network adaptersIf the list contains devices with the words Wireless, Wi-Fi, 802.11 (For example, Intel Wireless-AC 9560 or Qualcomm Atheros QCA61x4) - there is an adapter, but it disconnected or faultyIf you don't have such devices, proceed to the next connection methods.

🔍 How to enable a disabled adapter?

• 🖱️ Right-click on the adapter name and select Activate the device.
• 🔄 Restart your PC and check for network connectivity.
• 📥 If the adapter is marked with a yellow exclamation mark, update the driver (right-click → Update driver).

⚠️ Attention: On some motherboards, the Wi-Fi module is built in, but requires antennas to be connected (two small connectors MHF4 (on the back panel of the case). Without antennas, the network will have poor reception or no reception at all.

2. Connecting via a USB Wi-Fi adapter (the most reliable method)

If there is no built-in module, the easiest and cheapest way — buy external USB Wi-Fi adapterThese flash drive-sized devices plug into any available port and instantly prepare your PC for wireless networking. Prices start at 300–500 rubles for models with support Wi-Fi 4 (802.11n), to 2000–3000 rubles for adapters with Wi-Fi 6 (802.11ax) and external antennas.

🛒 How to choose an adapter?

• 📶 For basic use (social media, video) 720p) the adapter is enough for Wi-Fi 4 (speed up to 150–300 Mbps).
• 🎮 For online games or 4K-take streaming Wi-Fi 5 (802.11ac) with support 5 GHz.
• 📡 If the router is far away, look for a model with removable antenna (For example, TP-Link Archer T4U).

🔧 How to connect?

1. Insert the adapter into the USB port (preferably USB 3.0 for high-speed models).
2. Wait for the drivers to be installed automatically (in Windows 10/11 they are usually in the system).
3. If the driver is not installed, download it from the manufacturer's website (indicate the exact adapter model!).
4. Click on the network icon in the tray → select your Wi-Fi network → enter the password.

Make sure the adapter is detected in Device Manager|

Download the driver from the official website (if it is not installed automatically) |

Connect to a network with minimal security settings (WPA2)|

Check your speed on speedtest.net-->

⚠️ AttentionCheap, unbranded adapters (for example, the "Mini Wi-Fi Dongle" for 200 rubles) often have driver issues and slow speeds. It's better to pay extra for brand-name models.TP-Link, ASUS, D-Link).

3. Sharing the Internet from a smartphone (Wi-Fi Hotspot)

If you have a smartphone with mobile Internet at hand (4G/5G), Can turn it into an access point and connect your PC to the network via Wi-Fi. This method is suitable for temporary use, but it won't replace a full internet connection due to speed and data limitations.

📱 Instructions for Android:

1. Open Settings → Wireless & networks → Hotspot & tethering.
2. Activate Wi-Fi hotspot.
3. Set up a network name (SSID) and password (minimum 8 characters).
4. On your PC, connect to the created network as you would to a regular Wi-Fi network.

🍎 Instructions for iPhone (iOS):

1. Go to Settings → Tethering.
2. Turn on Allow others.
3. Enter your password (the default is your Apple ID password).
4. On your PC, select the network with the name of your iPhone.

⚡ Pros and cons of the method:

4. Connection via Ethernet (cable from the router)

If your PC is located next to the router, the most stable and fastest way — connect via cable Ethernet (aka "twisted pair"). Even if you don't have Wi-Fi, 99% of computers have a network card for a wired connection (connector RJ-45 on the back panel).

🔌 What you will need:

• 📶 Ethernet cable (length depends on the distance to the router).
• 🖥️ Free port LAN on the router (usually yellow).

⚙️ How to connect:

1. Connect the port with a cable LAN on the router and the connector Ethernet on PC.
2. Wait for the network to be configured automatically (a connection icon will appear in the tray).
3. If the Internet doesn't work, check your router settings (it should be turned on). DHCP).

💡 What to do if the cable is too short?

• 🔄 Buy Ethernet extender (to 50 meters without loss of speed).
• 📡 Use Powerline adapters (they transmit the Internet through electrical wiring).
• 🔌 If the router is far away, move it closer or run the cable along the baseboard.

⚠️ AttentionSome internet providers bind access to the device's MAC address. If the internet still doesn't work after connecting the cable, call support and provide the new MAC address (you can find it in the command ipconfig /all V Command line).

5. Using a second device as a bridge (Wi-Fi Bridge)

If you have a laptop, tablet, or even a second PC with working Wi-Fi, you can turn it into a "bridge" and distribute the Internet to the main computer through Ethernet or USBThis method is more complicated than the previous ones, but is useful if there are no other options.

🖥️ Method 1: Sharing via Ethernet (Windows)

1. On a device with Wi-Fi, open Settings → Network & Internet → Mobile hotspot.
2. In the section Distribution via select Ethernet.
3. Connect both PCs network cable (crossover or regular) LAN).
4. On the main PC in Network connections Enable obtaining IP address automatically.

🔗 Method 2: USB connection (Android)

• 📱 Connect your smartphone to your PC via USB.
• 🔄 Turn it on on your phone USB modem (Settings → Wireless & networks → Tethering & portable hotspot).
• 🖥️ A new network connection will appear on your PC (usually Remote NDIS).

⚠️ Limitations of the method:

• ⏳ Delay (ping) will be higher than with a direct connection.
• 📉 The speed is limited by the capabilities of the "bridge" (for example, if the laptop catches Wi-Fi on 50 Mbps, then the PC will receive no more).
• 🔌 When distributing through USB the phone will discharge faster.

How to check connection speed via a bridge?

Open Command Prompt (Win + R → enter cmd → Enter).

Enter the command ping ya.ru - if the response time (ms) more 100, the connection is unstable.

To test your speed, use the website speedtest.net (but remember that the result will be limited by the capabilities of the "bridge").

6. Internal installation of the Wi-Fi module (for advanced users)

If you are willing to spend time upgrading your PC, you can install an internal Wi-Fi module in the slot PCIe or M.2This solution is suitable for desktop computers and provides maximum speed and stability connections.

🛠️ What you will need:

• 🖥️ Wi-Fi card For PCIe x1 (For example, TP-Link Archer TX3000E with support Wi-Fi 6).
• 🔧 Screwdriver and antistatic wrist strap (optional).
• 📡 Antennas (usually included with the card).

🔧 Step-by-step installation:

1. Turn off your PC and disconnect the power cable.
2. Remove the side cover of the case.
3. Find a free slot PCIe x1 (usually the shortest).
4. Place the card into the slot and secure it with a screw.
5. Connect the antennas to the connectors on the card and route them outside (for example, through the rear grill of the case).
6. Assemble your PC, turn it on, and install the drivers from the disc or the manufacturer's website.

💰 Cost and characteristics of popular modules:

⚠️ Attention: When installing a Wi-Fi card in PCIe x16 (long video card slot) it will work, but it may block other devices. Use only PCIe x1.
