Want to connect your desktop computer to Wi-Fi, but it doesn't have a built-in wireless adapter? Don't rush to buy a new USB dongle—you might already have a ready-made solution! Wi-Fi receiver from a laptop It can be adapted for use with a desktop PC, saving time and money. In this article, we'll explore all possible options: from physically moving the module to software solutions using a laptop as a repeater.
The lack of Wi-Fi on a desktop computer is a common problem for many: a wired connection isn't always convenient, and purchasing a separate adapter requires additional costs. Meanwhile, Intel Wireless-AC 9560, Broadcom BCM4352 or other popular modules from laptops often support the standard M.2 2230 or PCIe — the same interfaces used on PC motherboards. The main thing is to correctly determine the connector type and compatibility with your system.
We'll cover not only hardware methods (moving the module or connecting via an adapter) but also software ones—for example, how to turn a laptop into a hotspot for a computer. Each method has its pros and cons: some require disassembling the device, others require driver configuration, and in some cases, a few clicks in Windows settings are all that's needed. Choose the best option based on your technical skills and the equipment you have available.
1. How to determine the type of Wi-Fi module in a laptop
Before you try to connect the module to your computer, you need to find out its physical interface and model. This determines whether you can move it at all or whether you'll need to buy an adapter. Most modern laptops are equipped with three types of modules:
- 🔹 M.2 2230 (Key A/E) — the most common format for Wi-Fi + Bluetooth modules (for example, Intel AX200, Qualcomm QCA61x4). Suitable for most PC motherboards via adapter.
- 🔹 PCIe Mini Card — an outdated standard, found in laptops before 2015 (for example, Broadcom BCM4313). Requires an adapter
PCIe x1. - 🔹 USB (internal) — rare, but used in some Ultrabooks (the module is connected via an internal USB port). Transferring is only possible with a soldering iron.
To find out the exact module model:
- Open
device Manager(keysWin + X→device Manager). - Expand the branch
Network adapters. - Look for devices with names like Wireless, Wi-Fi or 802.11 (For example, Intel(R) Dual Band Wireless-AC 8265).
- Right click →
Properties→ tabIntelligence→ selectEquipment ID. In the lineVEN_XXXXAndDEV_XXXXThe manufacturer and model are coded.
If the Device Manager doesn't show the model (for example, due to missing drivers), disassemble the laptop and look for the markings on the module itself. These are usually found on a sticker in the format Model: XXXX or P/N: XXXXFor laptops Lenovo, HP And Dell You can also use service utilities like Lenovo Vantage or HP Support Assistant.
⚠️ Attention: If your laptop was released before 2010, its Wi-Fi module may only support outdated standards.802.11n(maximum 300 Mbps). For modern networks, it is better to use modules no older than 2016 (support802.11acorWi-Fi 6).
2. Method 1: Moving the Wi-Fi module to the computer's M.2 or PCIe slot
The most reliable method is to physically install the module from the laptop onto the PC's motherboard. This is possible if:
- 🔧 Your computer has a free slot
M.2 Key A/E(less often -Key Mwith Wi-Fi support). - 🔧 The module from the laptop is compatible with the interface (most M.2 2230 (they are suitable).
- 🔧 There are antenna connectors on the motherboard (usually marked as
MAINAndAUX).
Step-by-step instructions:
- Remove the module from the laptop:
- Disconnect the laptop from the power supply and remove the battery.
- Unscrew the back cover (usually the module is located under a small removable panel with an antenna symbol).
- Disconnect the two antenna wires (gently pull on the connectors)
U.FLorIPEX). - Loosen the screw securing the module and remove it.
- Install the module on your PC:
- Find the slot on the motherboard
M.2 Key A/E(usually located near the rear panel of the case). - Insert the module at an angle of 30° and secure with a screw.
- Connect the antennas (included with the motherboard or purchased separately).
- Find the slot on the motherboard
- Download the driver for your model from the manufacturer's website (for example, Intel or Qualcomm).
- IN
Device ManagerUpdate the driver manually by specifying the path to the downloaded file.
If there is no slot on the motherboard M.2 Key A/E, can be used PCIe x1 adapter (cost ~500–1500 ₽). For example, for modules Intel AX200 an adapter will fit M.2 NGFF to PCIe with support CNVi (for Intel processors of 8-11 generations).

3. Method 2: Connection via USB adapter (for modules with USB interface)
If your laptop's Wi-Fi module uses USB interface (For example, Realtek RTL8188EU or Ralink RT5370), it can be connected to a PC via USB-A port using an adapter. This method is suitable for Ultrabooks, where Wi-Fi is integrated into the board via an internal USB port.
You will need:
- 🔌 Adapter
M.2 NGFF (Key A/E) to USB(approximately 600–1200 ₽ on AliExpress). - 🔌 USB extension cable (optional if the PC case interferes with the connection).
- 🔌 Drivers for the module (download from the manufacturer's website, not from the disk included with the adapter!).
Instructions:
- Connect the module to the adapter
M.2 to USB(observe the keys -Key AorKey E). - Insert the adapter into the USB port of your computer. Use the port
USB 3.0(blue connector) for stable operation. - Wait for the drivers to install (Windows will try to install them automatically). If the network adapter is in
Device ManagerIf there is no driver or it is marked with an exclamation mark, install the driver manually. - Connect to Wi-Fi via the taskbar (network icon → select network → enter password).
Advantages of the method:
- ✅ Does not require disassembling the PC (connection via USB).
- ✅ Compatible with any computer, even those without free slots
M.2/PCIe.
Flaws:
- ❌ There may be problems with connection stability (the USB interface is less reliable than
PCIe). - ❌ Not all modules support this connection method (check the specifications!).
4. Method 3: Using a laptop as a Wi-Fi repeater (without disassembling)
If you don't want to disassemble your laptop or computer, you can force the laptop distribute the Internet via cable or a second Wi-Fi networkThis method does not require any equipment other than a network cable. Ethernet (or USB-C adapter for modern ultrabooks).
Customization options:
Option A: Sharing Wi-Fi over Ethernet (Bridge)
- Connect the laptop to the computer with a cable
Ethernet(to the portLANon PC andRJ-45on a laptop). - On your laptop, open
Settings → Network & Internet → Mobile Hotspot. - Enable the option
Allow other devices to use my internet connection. - In the section
SharingselectEthernetas a connection method.
Option B: Create a virtual router (via command line)
If the bridge doesn't work, create a virtual access point:
netsh wlan set hostednetwork mode=allow ssid=MyWiFi key=12345678
netsh wlan start hostednetwork
Then in Control Panel → Network and Internet → Network and Sharing Center → Change adapter settings find a new connection (for example, Local Area Connection* 12), right-click → Properties → tab Access → Allow internet sharing.
Advantages of the method:
- ✅ Does not require disassembling the equipment.
- ✅ Works even with outdated modules (for example,
802.11g). - ✅ You can use your laptop as a repeater for multiple devices.
Flaws:
- ❌ The laptop must be turned on at all times.
- ❌ Speed is limited by bandwidth
Ethernetor USB adapter. - ❌ Delays may occur when playing online games or making video calls.

5. Method 4: Purchase an adapter for external antenna connection
If your laptop's Wi-Fi module supports removable antennas (connectors U.FL or IPEX), it can be connected to a PC externally, using antenna extenders and a USB/PCIe adapter. This is relevant for modules like Intel 7260 or Killer Wireless-AC 1550, where the antennas are easily detached.
Necessary components:
- 📡 Antenna extenders
U.FL → SMA(length 15–30 cm, ~300 ₽ per pair). - 🖥️ Adapter
M.2 NGFF to PCIeorM.2 to USB(depending on the module interface). - 📶 External antennas with connector
SMA(optional, to enhance the signal).
How to connect:
- Disconnect the antennas from the module in the laptop.
- Connect extension cords
U.FL → SMAto the connectorsMAINAndAUXon the module. - Install the module into the adapter (
PCIeorUSB). - Connect the adapter to your PC and install the drivers.
- Attach the antennas to the PC case (for example, to the back wall) for better reception.
Important: When using antenna extensions, the cable length should not exceed 30 cm, otherwise significant signal loss will occur (up to 3 dB for each additional meter). For stable operation, choose cables with low attenuation (e.g. RG-174 or LMR-100).
What should I do if Wi-Fi doesn't work after connecting?
1. Check if the module is detected in Device ManagerIf not, the problem is in the physical connection (recheck the contacts).
2. If the module is present but without drivers, download them from the official website (do not use drivers from disks or third-party websites!).
3. For modules Intel may need to be disabled CNVi in BIOS (section Advanced → Wireless Configuration).
4. If the signal is weak, try swapping the antennas (MAIN And AUX).
6. Possible problems and their solutions
Even with a proper connection, difficulties can arise. Let's look at typical scenarios and how to resolve them:
| Problem | Possible cause | Solution |
|---|---|---|
The module is not defined in Device Manager |
Incompatibility with the interface (eg. CNVi (no support in BIOS) |
Update your motherboard BIOS or use an adapter that supports it. CNVi. |
| Wi-Fi connects, but there is no internet | Sharing is not configured or there is a problem with DHCP | Check your settings IPv4 (should be there) Receive automatically). |
| Low connection speed (up to 50 Mbps) | The module operates in the mode 802.11n instead of 802.11ac |
Update the driver and check the router settings (enable WPA2-AES and turn it off 802.11b). |
| Constant connection breaks | Interference from other devices or weak signal | Change the Wi-Fi channel in the router settings (for example, to 6 or 11 for 2.4 GHz). |
If after all these steps Wi-Fi still doesn't work, check:
- 🔍 Module compatibility with your OS: some adapters (eg Broadcom BCM4360) require manual installation of drivers in Linux or older versions of Windows.
- 🔍 BIOS settings: on some motherboards (eg. ASRock) you need to manually enable support
PCIe Wi-Fiin the sectionAdvanced → Onboard Devices Configuration. - 🔍 Device conflicts: If there is another Wi-Fi adapter already installed in the system, disable it in
Device Manager.
⚠️ Attention: On laptops with processors Intel 10-12 generations some Wi-Fi modules (for example, Intel AX210) use a proprietary interfaceCNVi, which is not compatible with standard slotsM.2 Key A/EIn this case, you will need a special adapter with supportCNVi(For example, M.2 NGFF CNVi to PCIe).
7. Comparison of methods: which one to choose?
To help you decide, we've compiled the key pros and cons of each method in one table:
| Method | Complexity | Price | Stability | When to use |
|---|---|---|---|---|
Moving the module to M.2/PCIe |
⭐⭐⭐ (requires disassembly) | 0–1500 ₽ (if you need an adapter) | ⭐⭐⭐⭐⭐ | For permanent use on the main PC |
Connection via USB adapter |
⭐⭐ (minimal disassembly) | 500–1200 ₽ | ⭐⭐⭐ | If there are no free slots M.2/PCIe |
| Laptop as a repeater | ⭐ (without disassembly) | 0 ₽ | ⭐⭐ | For a temporary solution or if the module is incompatible |
| External antennas + adapter | ⭐⭐⭐⭐ (soldering/extensions) | 1000–2500 ₽ | ⭐⭐⭐⭐ | To boost the signal in a weak coverage area |
If your goal is - maximum speed and stability, the best option is to move the module to the slot M.2/PCIeFor a temporary solution or if you lack technical skills, retransmitting via a laptop is a suitable option. A USB adapter is a good middle ground, but be aware of potential lag under heavy loads (such as online gaming).
