Your internet stopped working after a Windows 11 update. Or maybe you just built a new PC and can’t get online. The problem is usually your network adapter driver.
This guide shows you exactly how to install, update, and fix network adapter drivers in Windows 11. You’ll get your connection working again.
What Is a Network Adapter Driver and Why Does It Matter?
A network adapter driver is software that helps Windows 11 communicate with your network hardware. Without the right driver, your Wi-Fi or Ethernet won’t work.
Think of it like a translator. Your operating system speaks one language, your network card speaks another. The driver translates between them.
Common signs you need to install or update your network adapter driver:
- No internet connection after Windows update
- Yellow exclamation mark in Device Manager
- “No Wi-Fi networks found” error
- Ethernet cable connected but no internet
- Slow or unstable connection speeds
Quick Fix: Let Windows 11 Install the Driver Automatically
Windows 11 can usually find and install network drivers for you. Try this first.
Step 1: Right-click the Start button and select Device Manager.
Step 2: Find “Network adapters” and click the arrow to expand it.
Step 3: Right-click your network adapter (it might say Intel, Realtek, Qualcomm, or MediaTek).
Step 4: Select “Update driver.”
Step 5: Click “Search automatically for drivers.”
Windows will search online and install any available driver. This works if you have a working internet connection through another device or Ethernet.
If Windows says “The best drivers for your device are already installed,” move to the manual methods below.
Method 1: Download and Install Network Adapter Drivers from Manufacturer Website
This is the most reliable way to get the correct driver.
Finding Your Network Adapter Model
Before downloading anything, you need to know what network adapter you have.
Option A: Check Device Manager
- Open Device Manager (right-click Start button)
- Expand “Network adapters“
- Look at the adapter name (example: “Intel Wi-Fi 6 AX201”)
- Write down the full name
Option B: Check System Information
- Press Windows key + R
- Type
msinfo32and press Enter - Expand “Components” then click “Network” then “Adapter”
- Find your adapter and note the name
Option C: Check Your PC or Motherboard Documentation
If you built your PC, check your motherboard manual. The network chip is listed in the specifications.
Downloading the Correct Driver
Once you know your adapter model, visit the manufacturer’s website. Here are the main ones:
- Intel: Intel Download Center
- Realtek: Visit your PC or motherboard manufacturer’s support page
- Qualcomm/Killer: Killer Networking website
- MediaTek: Your PC manufacturer’s support page
- Broadcom: Your PC manufacturer’s support page
Important: For laptop users, always download from your laptop manufacturer’s website (Dell, HP, Lenovo, etc.) rather than the chip maker. Laptop manufacturers customize drivers for their specific hardware.
Steps to Download
- Go to the manufacturer’s support or downloads page
- Enter your product model or adapter name
- Select Windows 11 as your operating system
- Download the latest driver (usually a .exe or .zip file)

Understanding Network Adapter Types in Windows 11
Windows 11 supports several network adapter types. Knowing yours helps with troubleshooting.
Wi-Fi adapters: Built into laptops or added via PCIe card or USB. Common brands: Intel, Qualcomm, MediaTek, Realtek.
Ethernet adapters: For wired connections. Usually Realtek, Intel, or Broadcom. Built into motherboards or added via PCIe.
USB network adapters: Plug-and-play dongles for Wi-Fi or Ethernet. May need manual driver installation.
Bluetooth adapters: Often combined with Wi-Fi on modern systems. Use the same driver package.
Each type has specific driver requirements. Always match the driver to your exact hardware.
Advanced: Installing Drivers in Safe Mode
If Windows 11 won’t boot normally, install drivers in Safe Mode with Networking.
- Power on your PC
- When you see the Windows logo, hold the power button to force shutdown
- Repeat this 2-3 times
- Windows will enter Recovery Environment
- Click “See advanced repair options”
- Troubleshoot → Advanced options → Startup Settings → Restart
- Press 5 or F5 for “Safe Mode with Networking”
- Install your driver normally
- Restart
This bypasses startup programs that might interfere with driver installation.
Common Network Adapter Driver Errors and Fixes
“Code 10: This device cannot start”
Fix: Completely remove the driver, restart, and reinstall.
“Code 28: The drivers for this device are not installed”
Fix: Manually install the driver using the methods above.
“Windows found a driver but encountered an error”
Fix: The driver might be corrupted. Download a fresh copy from the manufacturer.
“The specified module could not be found”
Fix: Run Windows Update, then try installing again. Missing system files may be the cause.
For more technical troubleshooting, Microsoft’s official support documentation provides detailed error code explanations at Microsoft Support.

Frequently Asked Questions
How do I know if my network adapter driver is missing in Windows 11?
Open Device Manager and look under Network adapters. If you see a yellow exclamation mark, question mark, or the adapter is missing entirely, you need to install the driver. You’ll also have no internet connection and Windows will show “No connections available” in the network icon.
Can I install network adapter drivers from Windows Update?
Yes. Go to Settings → Windows Update → Check for updates. Then click Advanced options → Optional updates → Driver updates. Select any network adapter drivers and install them. However, manufacturer websites often have newer versions than Windows Update.
What if Windows 11 says the best drivers are already installed?
This means Windows Update doesn’t have a newer version. Download the driver directly from your network adapter or PC manufacturer’s website. Manually install it using Device Manager by selecting “Browse my computer for drivers” instead of automatic search.
How do I install network drivers without internet access?
Use another computer or phone to download the driver. Transfer it to your PC using a USB flash drive. Alternatively, enable USB tethering from your smartphone to give your PC temporary internet access, then download and install the driver.
Should I update my network adapter driver if everything works fine?
Update if the new driver offers security patches or fixes known bugs. Otherwise, if your internet connection is stable and fast, you can skip updates. Check every few months for important updates, but don’t update just for the sake of it. If it’s not broken, sometimes it’s best not to fix it.
