Wi-Fi connection issues are one of the most common problems with laptops and PCs equipped with wireless adapters. Outdated, damaged, or incompatible adapters are often the culprit. Wi-Fi drivers, which are responsible for the proper operation of the network module. Even if your adapter is working properly, the wrong driver version can lead to connection drops, slow internet speeds, or a complete lack of available networks.
In this article we will look at Three main ways to update Wi-Fi drivers — from manual search through device Manager to automatic installation using specialized utilities. We will pay special attention to typical errors (for example, Code 10 or Code 43 in the manager) and explain how to avoid conflicts between versions. The instructions are relevant for Windows 10 And Windows 11, as well as most popular adapters from Intel, Qualcomm Atheros, Realtek, Broadcom And Mediatek.
Before you begin updating, check to see if the driver is the problem. If the Wi-Fi indicator on your laptop is off or blinking orange, and Networks and the Internet If the "No connections available" status is displayed, the software is most likely to blame. In rare cases, the problem could be hardware-related—for example, a broken antenna or a damaged adapter chip. However, in 90% of cases, reinstalling the driver resolves the issue.
1. How to determine the Wi-Fi adapter model and current driver
Before updating, you need to know the exact model of the wireless adapter and the version of the installed driver. This will help you download the correct software and avoid conflicts. This can be done in several ways:
- 🔍 Through
device Manager: clickWin + X→ Select “Device Manager” → Expand the “Network Adapters” tab. Look for devices with names Wireless, Wi-Fi, 802.11ac or brands Intel, Realtek and others. - 📋 Through
System Information: type in Windows searchmsinfo32→ Go to "Components" → "Network" → "Adapter." The full model name will be listed here. - 💻 Through
Command line: run it as administrator and enter:wmic nic where "NetConnectionStatus=2" get Name, Manufacturer, DriverVersionThe command will display the adapter name, manufacturer, and driver version.
Please note: If in Device Manager An exclamation mark (⚠️) appears next to the adapter name, which means the driver is not working properly or is missing. Error code 43 often indicates a hardware failure, but in 70% of cases it can be resolved by reinstalling the software. Also check if your adapter is listed under "Other devices" - this is a sign that the driver is missing completely.
⚠️ Attention: On some laptops (eg. Lenovo or HP) The integrated Wi-Fi module may be disabled in the BIOS. If the adapter is not detected by any of the methods, check the BIOS settings (section Advanced → Wireless Device).
2. Method 1: Update the driver via Device Manager
The simplest method is to use Windows' built-in tools. This is suitable if the system already recognizes the adapter, but the driver is outdated or not working correctly. Here are the step-by-step instructions:
- Open
device Manager(Win + X → Device Manager). - Expand the “Network adapters” category, find your Wi-Fi module (for example, Intel(R) Wi-Fi 6 AX200).
- Right-click on it → “Update driver”.
- Select "Search automatically for driver software." Windows will attempt to find and install the latest version from its database.
If the system reports that "the most suitable drivers are already installed"," this isn't always true. The built-in Windows database often contains outdated versions. In this case:
- 🔄 Try the second option: "Browse my computer for driver software" → "Choose from a list of currently installed drivers." Sometimes, there are more recent versions available here than the current one.
- 🗑️ If the adapter is unstable, instead of updating, select "Uninstall device" (with the "Delete the driver software for this device" checkbox checked), then restart your PC. Windows will reinstall the driver the next time you turn it on.
Download the driver from the official website
Create a system restore point
Disable antivirus software during installation.
Connect your PC to the Internet via cable (if possible) -->
⚠️ Attention: After uninstalling the driver, your Wi-Fi adapter will stop working until you reboot. If you connect to the internet through it, download a new driver. in advance or use a wired connection.
3. Method 2: Installing the driver from the manufacturer's official website
If the automatic update doesn't help, download the driver from the adapter or laptop manufacturer's website. This is the most reliable method, as you get the latest stable version, optimized for your device.
Algorithm of actions:
- Determine the adapter manufacturer (See Section 1). Popular brands:

7. What to do if nothing helps?
If after all these steps Wi-Fi still doesn't work, consider the following steps:
- 🔍 Check for hardware failure:
- For PCI-e cardsRemove the adapter from the slot and check the contacts for corrosion. Try inserting it into a different slot.
- For USB adapters: test on another PC.
- For built-in modules In a laptop: disassemble the device and check the antenna connections (thin black wires to the Wi-Fi module).
- 🖥️ Install Windows again: If the problem appeared after an OS update or a virus attack, a clean installation may help.
- 🔧 Contact the service center: If the adapter is not detected even in the BIOS, the chip or controller may be faulty.
To diagnose hardware problems, use Live CD with Linux (for example, Ubuntu). If Wi-Fi doesn't work there either, it's a hardware issue. If it works, it's a Windows issue (drivers, settings, software conflicts).
⚠️ Attention: On some laptops (especially Dell Latitude or HP EliteBook) The Wi-Fi module can be blocked through UEFI According to the company's security policy, in this case, a BIOS reset or contacting the corporate network administrator is required.
FAQ: Frequently asked questions about updating Wi-Fi drivers
