Below are detailed instructions with photos, selection tips, and answers to frequently asked questions.

How do you know if your Wi-Fi adapter needs replacing?

Before disassembling your laptop, make sure the problem is with the module itself, and not with software settings or the router. Here are the key signs physical failure of the adapter:

• 🔌 The laptop does not see any networks, although other devices (smartphone, tablet) connect without problems.
• 🔄 Networks are displayed, but the connection constantly drops, even if I stand next to the router.
• 🐢 Internet speed drops to 1-5 Mbps, although via cable or on other devices it is 100+ Mbps.
• ⚠️ In the Device Manager (Win + X → Device Manager → Network Adapters) there is an exclamation mark next to the module name or it is missing altogether.
• 🔧 After reinstalling Windows, the Wi-Fi driver is not installed, the system writes "Device not recognized".

If at least one of these symptoms appears, the probability of hardware failure of the adapter is 90%. But before replacing it, try reset network settings and update the driver:

• Disconnect the two antenna cables (black and white). Pull the connector, not the wire!
• Loosen the screw securing the module and carefully pull it out of the slot. M.2.

Step 3: Install the new adapter

1. Insert the new module into the slot at an angle of ~30° and press lightly until it "sits" in the connector.

3. Connect the antenna cables: black - to the MAIN connector, white - to AUX.

Step 4: Assemble the laptop and test its operation

1. Replace the back cover and tighten the screws.
2. Turn on your laptop and check if the new adapter is detected. Device Manager.
3. If necessary, install the driver from the adapter manufacturer's website (Intel, Qualcomm).

If Wi-Fi doesn't work after replacement, check:

• Are the antennas connected correctly (mixed cables give a weak signal).
• Is the BIOS updated (in ThinkPad this is critical).
• Is there an option in BIOS? "Wireless LAN Whitelist" - It needs to be turned off.

What to do if the new adapter is not detected?

1. Check if your model supports non-original modules (in ThinkPad a BIOS patch is often required).

2. Try installing the driver manually through Device Manager → Update Driver Software → Browse my computer.

3. If the adapter is defined as "Unidentified device", download the driver from the module manufacturer's website, not from the Lenovo website.

Setting up drivers and BIOS after replacement

Even if the new adapter is physically installed, it won't work without the correct drivers. Here's what to do:

1. Installing drivers

• 🔗 Download the driver from the adapter manufacturer's website:
  • Intel AX200/AX210: Intel's official website
  • Qualcomm QCA61x4: support.qualcomm.com
• 📁 Install the driver manually via device Manager, if the automatic installation did not work.

2. BIOS setup (for ThinkPad and some Ideapads)

1. Restart your laptop and enter BIOS (button F1, F2 or Del when loading).
2. Find the section Security → I/O Port Access or Advanced → Wireless.
3. Disable the option "Wireless LAN Whitelist" (if any).
4. Save settings (F10) and reboot.

3. Checking the work

• 📶 Make sure your laptop sees and connects to networks.
• 📊 Check your speed on Speedtest - it must correspond to the tariff.
• 🔄 If the speed is low, try changing the channel on your router (in the router settings, select 1, 6 or 11 for 2.4 GHz).

⚠️ Attention: In some models Lenovo Legion (For example, Y540) after replacing the adapter, an error may occur "1802: Unauthorized network card"This means the BIOS is blocking the module. The solution is to update the BIOS to the latest version or use a community patch (search the forums). NotebookReview or Reddit).

Common mistakes and how to avoid them

Even experienced users sometimes make mistakes when replacing a Wi-Fi adapter. Here are the most common ones:

• 🔌 Tangled antenna cables - if you change MAIN And AUX in some places, the speed will drop by 2-3 times.
• 🔧 The module is not tight enough to fit the connector. — the adapter should “click” when installed.
• 📋 Ignoring BIOS update - especially critical for ThinkPad and new ones Legion.
• 💻 Attempting to install a Lenovo driver on a non-genuine adapter — Download the driver from the module manufacturer's website!

If the adapter is unstable after replacement:

1. Check if the contacts on the module are dirty (wipe with alcohol).
2. Make sure that the antenna cables are not pinched or damaged.
3. Try rolling back the driver to the previous version (sometimes new drivers are glitchy).

In rare cases the problem may be in faulty M.2 slotTo check this, try installing the old adapter in a different laptop. If it works, the slot is at fault, and the motherboard will need to be repaired.

Alternative Wi-Fi connection methods if replacement doesn't help

If problems persist even after replacing the adapter, or you don't want to disassemble the laptop, there are workarounds:

• 📡 USB Wi-Fi adapter - external module (for example, TP-Link TL-WN823N or ASUS USB-AC56). It plugs into a USB port and requires no disassembly. The downside is that it takes up a USB port and sticks out on the side.
• 🔌 Powerline adapter — transmits internet through electrical wiring. Useful if the router is far away and the signal is weak.
• 📱 Sharing Internet from a smartphone — a temporary solution, but convenient for traveling.
• 🖥️ Ethernet over USB - adapter USB-to-RJ45 (For example, Baseus or TP-Link UE300) for connection via cable.

If you have chosen USB adapter, please note:

• Wi-Fi standard (take 802.11ac or 802.11ax).
• The presence of an external antenna (improves reception).
• Support for your OS (some adapters do not work on Linux).
