No Wi-Fi After Reinstalling Windows? How to Fix Wi-Fi on a Fresh Windows Install

If the wireless adapter still doesn't appear, continue with the troubleshooting steps below.

A fresh Windows installation often means missing drivers, incorrect settings, or default configurations that aren't optimized for your device.

Here are some of the most common reasons:

• Network adapter driver not installed or outdated.
• Wi-Fi adapter disabled by default.
• Wrong DNS or IP settings.
• Airplane mode was accidentally turned on.
• Corrupted system files.

Understanding the problem is the first step toward fixing it.

Let's dive into the most effective solutions you can try.

1. Check if Wi-Fi Is Turned On

Go to the bottom-right corner of your screen and click the network icon. If Wi-Fi is off, turn it on.

Some laptops also have physical switches or function keys, such as Fn + F2, to enable or disable wireless connectivity.

2. Update or Install Network Drivers

One of the most common issues after reinstalling Windows is missing or outdated network drivers.

If your Wi-Fi adapter is missing after reinstalling Windows or you see the network adapter missing in Windows 11, open Device Manager → Network adapters and check:

• Is the adapter listed but disabled?
• Is it under “Other devices” with a warning symbol?
• Try “Action → Scan for hardware changes” to force detection.

Steps:

• Open Device Manager from the Start menu.
• Expand the Network adapters section.
• Look for items with a yellow exclamation mark.
• Right-click your Wi-Fi adapter and choose Update driver.
• If the driver isn't found, visit your computer manufacturer's official support website and download the correct network driver.

Reinstalled Windows and Now There's No Wi-Fi?

If you reinstalled Windows and now have no Wi-Fi, start by checking the network drivers before changing your router or advanced network settings.

After a fresh Windows installation, Windows may not automatically install the correct chipset or wireless network adapter driver for your computer.

Try these steps in order:

• Open Device Manager and expand Network adapters.
• Check Other devices for an unknown Network Controller or a device with a yellow warning icon.
• Install the latest chipset drivers from your computer manufacturer.
• Install the correct Wi-Fi or WLAN driver for your exact computer model.
• Restart the computer.
• Run Windows Update and install available driver and system updates.

If you're seeing “No Wi-Fi networks available” during Windows 11 setup (OOBE), it usually means Windows setup can't detect your wireless card because the Wi-Fi driver isn't loaded yet.

This is especially common on newer laptops after a fresh Windows installation.

How to Install the Wi-Fi Driver During Windows 11 Setup

• On another computer, go to your laptop manufacturer's official support page.
• Download the Wi-Fi driver for your exact computer model and Windows 11.
• If the download is a ZIP file, extract it and make sure the folder contains the required driver files, including INF files when provided.
• Copy the extracted driver folder to a USB flash drive.
• Return to the Windows setup network screen and choose Install driver.
• Select the driver folder on the USB drive.
• Once Windows loads the wireless driver, check whether your Wi-Fi networks appear.

If Windows 11 setup cannot detect a Wi-Fi network, you may see a prompt related to aka.ms/networksetup .

This usually happens when Windows does not have the correct network adapter or Wi-Fi driver available during setup.

Before assuming there is a hardware problem, check whether Windows simply needs the correct driver.

What to Do When Windows 11 Setup Shows No Wi-Fi

• On another computer, visit the support website for your PC or laptop manufacturer.
• Search for your exact computer model.
• Download the latest Windows 11 Wi-Fi or wireless network adapter driver.
• If the driver is provided as a ZIP file, extract it first.
• Copy the extracted driver files to a USB flash drive.
• Connect the USB drive to the computer you're setting up.
• Use the Install driver option on the Windows network setup screen and browse to the driver folder.
• Once Windows recognizes the wireless adapter, available Wi-Fi networks should appear.

Still Stuck on the Windows Network Setup Screen?

If aka.ms/networksetup , missing drivers, or an undetected Wi-Fi adapter is preventing you from completing Windows setup, MicroSec® can help determine the next troubleshooting step.

Once the computer has a temporary internet connection, such as Ethernet or supported phone tethering, our technicians can provide remote assistance with Windows drivers, network settings, and connectivity problems.

A common problem after reinstalling Windows is needing an internet connection to download a Wi-Fi driver while simultaneously needing the Wi-Fi driver to get an internet connection.

Fortunately, you have several options.

If the network adapter is not showing in Device Manager, Windows may not have the correct driver, the device may not have been detected properly, or the wireless hardware may be disabled.

Open:

Look for your wireless adapter. Its name may contain terms such as Wireless, Wi-Fi, WLAN, Intel, Realtek, MediaTek, Broadcom, or Qualcomm.

If you cannot find it, check Other devices for an Unknown device or Network Controller with a yellow warning symbol.

Then try:

• Device Manager → Action → Scan for hardware changes.
• Device Manager → View → Show hidden devices.

PC Has Ethernet but No Wi-Fi Option?

If your PC shows Ethernet but no Wi-Fi option, don't immediately assume the wireless card has failed.

After a fresh Windows installation, this often means Windows has recognized the Ethernet controller but has not loaded the correct wireless adapter driver.

Try these steps:

• Install the computer manufacturer's chipset drivers.
• Install the correct Wi-Fi/WLAN driver.
• Restart Windows.
• Check Device Manager again.
• Run Windows Update after internet connectivity is restored.

4. Turn Off Airplane Mode

Airplane mode can block Wi-Fi access.

• Go to Settings → Network & Internet → Airplane Mode.
• Make sure Airplane Mode is turned off.

5. Run the Network Troubleshooter

Let Windows check for common network configuration problems.

• Open Windows Settings and navigate to the network troubleshooting options available for your Windows version.
• Run the network or internet troubleshooter and follow the on-screen recommendations.

6. Reset TCP/IP Stack and Flush DNS

Network settings can sometimes become misconfigured.

Steps:

Open Command Prompt as an administrator and run the following commands:

Restart your PC after the commands have completed.

Wi-Fi Is Connected, but There's No Internet After Installing Windows

Seeing Connected, no internet is different from Windows having no Wi-Fi option at all.

If Windows can see and connect to your wireless network but websites will not load, try:

• Restart the computer and router.
• Forget the Wi-Fi network and reconnect.
• Make sure IP and DNS settings are configured to obtain addresses automatically.
• Temporarily disable a VPN to test for a software conflict.
• Run Windows Update.
• Reset Winsock and TCP/IP.
• Check whether other devices can access the internet through the same router.

7. Check for Windows Updates

Missing updates can affect hardware functionality.

• Open Windows Update from Settings.
• Check for available updates.
• Install available Windows and driver updates.
• Restart the computer when prompted.

Why Wi-Fi Issues Are Common After a Fresh Windows 11 Install

On newer Windows 11 systems, a fresh installation may not immediately include all the chipset and network drivers required by your computer's hardware.

This is especially common with newer laptops and PCs that use manufacturer-specific Wi-Fi adapters.

As a result, Windows may install successfully while the Wi-Fi option remains missing until the correct drivers are installed.

Best practice:

• Install the chipset drivers from your computer manufacturer first.
• Install the correct Wi-Fi or wireless network adapter driver.
• Restart the computer.
• Run Windows Update again to install additional driver and compatibility updates.

8. Manually Check IP and DNS Settings

Incorrect IP or DNS configuration can prevent connectivity.

• Open your network adapter settings.
• Open the properties for your Wi-Fi connection.
• Open Internet Protocol Version 4 (TCP/IPv4).
• Choose Obtain an IP address automatically.
• Choose Obtain DNS server address automatically.

9. Check for Software Conflicts

Antivirus, VPN, firewall, or other networking software may interfere with connectivity.

Temporarily disable relevant third-party networking or security software for testing, then check whether Wi-Fi starts working.

The same driver problem can occur after a fresh Windows 10 installation.

If Windows 10 has no Wi-Fi after reinstalling the operating system, open Device Manager and check whether the wireless adapter is detected.

If you see Network Controller, Unknown device, or a device with a yellow warning icon, download the correct Windows 10 network driver from the computer manufacturer's official website.

After installing the driver, restart the computer and check Windows Update for additional driver and compatibility updates.

Sometimes a Wi-Fi problem is only one symptom of a larger Windows issue.
