Method 1: Reinstall the driver via Device Manager

This is the simplest and safest method, which doesn't require an internet connection (if the driver is already installed on the system). It's suitable for most cases where Wi-Fi suddenly stops working after an update or a crash.

Step 1: Uninstall the current driver

Open device Manager → Find your Wi-Fi adapter in the section Network adaptersRight-click on it and select Remove device.

In the window that appears, check the box "Delete the driver software for this device" (if any) and confirm the action. This will completely clear the current settings.

Download a backup copy of the current driver (via Device Manager → Properties → Driver → Details)

Disable your antivirus (it may be blocking the installation)

Connect your laptop to the router via Ethernet cable (if possible)

Create a system restore point (in case of failure)-->

Method 2: Install the driver from the official website

If automatic reinstallation doesn't help, you'll have to download the driver manually. This is a more reliable method, as you'll get the latest and most compatible version.

What to do if reinstalling the driver doesn't help

If Wi-Fi still isn't working after all these steps, the problem may lie deeper. Here's what to check:

1. Hardware malfunctions

Unplug your laptop, remove the battery (if removable), and press the power button for 30 seconds to discharge static electricity. If Wi-Fi doesn't work after turning it on, the following may be damaged:

• 📡 Antenna cable (often comes off when disassembling the laptop).
• 🔌 The Wi-Fi module itself (burns out during power surges).

2. BIOS/UEFI settings

Go to BIOS (usually the key F2, Del or Esc (when turning it on) and check if the wireless adapter is enabled. Look for items like:

How to avoid Wi-Fi driver problems in the future

To avoid unexpected failures, follow these simple guidelines:

• 🔄 Update your drivers regularly — Check the manufacturer's website for new versions at least once every six months.
• 💾 Create backups — Before updating Windows or drivers, save the current working version (via Device Manager → Driver Properties → Roll Back Driver).
• ⚡ Use an uninterruptible power supply - sudden power outages can damage both the driver and the adapter itself.
• 🛡️ Check your laptop for viruses - Some malware deliberately damages network drivers.

If your laptop is under warranty, do not attempt to disassemble it yourself to check the antenna or Wi-Fi module—this will void the warranty. Contact a service center with a description of the problem.
