Wondering why my Wi-Fi is not Working After Installing Windows?

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• Network adapter driver not installed or outdated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.

How to Fix- Wi-Fi Not Working on a Fresh Windows Install?

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 (Fn + F2, for example) to enable or disable wireless connectivity.

2. Update or Install Network Drivers

One of the most common issues is missing or outdated network drivers.

Steps:

• Open Device Manager (search from the Start menu)

• Expand the Network adapters section

• Look for any items with a yellow exclamation mark

• Right-click your Wi-Fi adapter and choose Update driver

• If not found, visit your laptop manufacturer’s website to download and install the latest network drivers manually.

3. Enable Wi-Fi Adapter

Sometimes, your adapter may be disabled by default.

Steps:

• Press Windows + R, type ncpa.cpl, and hit Enter

• Right-click the Wi-Fi adapter > Click Enable (if it’s disabled)

4. Turn Off Airplane Mode

Airplane mode can block Wi-Fi access.

Steps:

• Go to Settings > Network & Internet > Airplane Mode

• Make sure it is turned off

5. Run the Network Troubleshooter

Let Windows try to fix itself.

Steps:

• Go to Settings > Update & Security > Troubleshoot > Additional troubleshooters

• Select Internet Connections and click Run the troubleshooter.

6. Reset TCP/IP Stack and Flush DNS

Network settings can sometimes be misconfigured.

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

netsh int ip reset

netsh winsock reset

ipconfig /release

ipconfig /renew

ipconfig /flushdns

Then restart your PC.

7. Check for Windows Updates

Missing updates can affect hardware functionality.

Steps:

• Go to Settings > Update & Security > Windows Update

• Install any available updates

8. Manually Set IP and DNS Settings

Incorrect IP settings can prevent connectivity.

Steps:

• Go to Control Panel > Network and Sharing Center > Change adapter settings

• Right-click your Wi-Fi network > Properties

• Double-click Internet Protocol Version 4 (TCP/IPv4)

• Choose Obtain an IP address automatically and Obtain DNS server address automatically

9. Check for Software Conflicts

Antivirus or VPN software might block Wi-Fi access. Temporarily disable these and check if Wi-Fi works.
