If your laptop ASUS If your Wi-Fi connection starts to drop, pages load slowly, or you can't see any networks at all, the problem could be a faulty wireless adapter. Replacing this module is one of the most easily repairable DIY procedures, requiring no soldering iron or in-depth knowledge of electronics. In this article, we'll cover the solution. all stages of installation: from choosing a compatible adapter to fine-tuning the drivers in Windows 10/11.

Feature of laptops ASUS (series VivoBook, ZenBook, ROG, TUF) - using standard slots M.2 2230 (less often) M.2 1216) for Wi-Fi modules. This means that you can choose a replacement from dozens of models from Intel, Qualcomm or BroadcomHowever, there are some nuances: some adapters require BIOS reflashing to work with ASUS, while others may not support Wi-Fi 6E on older motherboards. We'll tell you how to avoid these pitfalls.

Before you start disassembling your laptop, make sure that the problem is in the adapter. diagnostics — the drivers or router settings may be at fault. If the module is truly faulty, follow our instructions: they apply to 90% of models. ASUS the last 10 years.

1. How to check if your Wi-Fi adapter is faulty

Before purchasing a new module, rule out software glitches. Here are the key signs: physical malfunction adapter:

• 🔴 The laptop doesn't see it not a single one Wi-Fi network, although other devices connect normally.
• 🔴 In Device Manager There is an exclamation mark next to the adapter name (error code) 10, 43 or 45).
• 🔴 The signal disappears with the slightest movement of the case (for example, if you tilt the screen).
• 🔴 The adapter is defined as "Unknown device" even after reinstalling the drivers.

If at least one of these points matches, the module is likely faulty. But to be sure, follow these steps:

1. Open Command line (Win + R → enter cmd).
2. Enter the command:

   netsh wlan show drivers

   If there is no line in the response "Hosted Network Support: Yes", the adapter may be disabled at the BIOS level.

3. Check the module temperature using AIDA64 or HWMonitorIf it exceeds 70°C when idle, this is a sign of overheating (a common cause of failure).

Important! If the adapter is detected by the system, but does not catch the network, try reset network settings or update the drivers. Physical replacement is only necessary if complete lack of response to commands.

2. Selecting a compatible Wi-Fi adapter for ASUS

Laptops ASUS support adapters in the format M.2 2230 (less often) 1216 or 3042). To avoid making a mistake in your choice, consider:

• 📋 Form factor: 90% of models use 2230 (22 mm wide, 30 mm long). Game series ROG may have 3042.
• 📋 Interface: Modern adapters work according to PCIe + USB (For Wi-Fi 6/6E) or only USB (obsolete models).
• 📋 BIOS support: Some laptops ASUS Block non-original modules. Check the compatibility list on the manufacturer's website.
• 📋 Wi-Fi standard: It's enough for the office. Wi-Fi 5 (802.11ac), for games and 4K streams take Wi-Fi 6/6E (802.11ax).

How to check if Bluetooth works after replacing the adapter?

Bluetooth and Wi-Fi are usually combined into a single module. To check Bluetooth:

1. Open device Manager and find the section "Bluetooth".
2. If the device is missing or marked with an exclamation mark, reconnect it USB cable on the Wi-Fi module (it is responsible for Bluetooth).
3. Update the Bluetooth driver manually (download from the adapter manufacturer's website).

If Bluetooth still doesn't work, check:

• Are both antenna cables connected (Bluetooth uses AUX-antenna).
• Is there any physical damage to the connector? USB module.

Is it possible to use an adapter from another laptop (for example, Lenovo or HP)?

Yes, but subject to three conditions:

1. Form factor must match (M.2 2230 or 1216).
2. Interface must be compatible (most adapters use PCIe + USB).
3. No BIOS connectionSome laptops ASUS block "foreign" modules (especially in business lines).

Adapters from work best Intel And Qualcomm - They are universal. Adapters from Broadcom or Realtek may require manual installation of drivers.

What should I do if my laptop starts to get hotter after replacing the adapter?

An increase in temperature may be associated with:

• Bad contact between the adapter and the radiator (if any). Solution: Apply a thin layer of thermal paste to the metal cover of the module.
• Increased load on the processor when working with Wi-Fi 6. Solution: Disable background downloads in Settings → Network → Data.
