How to Enable Wi-Fi in BIOS on Windows 11: A Step-by-Step Guide

Have you ever tried connecting to Wi-Fi on your Windows 11 laptop, only to discover that the Wi-Fi option is missing entirely? Don’t panic—it’s not always a driver issue. Sometimes, Wi-Fi is disabled at the BIOS level, which prevents Windows from even detecting your wireless card.

In this guide, we’ll walk you through how to enable Wi-Fi in BIOS on Windows 11 step by step, why it matters, and what to do if Wi-Fi still doesn’t appear after enabling it.

Key Takeaways (Quick Summary)

✅ Some laptops allow enabling or disabling Wi-Fi directly from the BIOS/UEFI firmware.
✅ If Wi-Fi is disabled in BIOS, Windows 11 won’t detect your wireless card at all.
✅ You can access BIOS by pressing a specific function key (F2, F10, F12, DEL, ESC) while booting.
✅ After enabling Wi-Fi, you may also need to update drivers in Windows.
⚠️ Not all BIOS versions have a Wi-Fi toggle—some systems always keep it enabled.

What is BIOS and Why Does it Control Wi-Fi?

The BIOS (Basic Input/Output System) or UEFI firmware is the software that runs before Windows boots. It controls low-level settings like:

Boot order
Security features
Integrated device controls (USB, LAN, Wi-Fi, Bluetooth)

Manufacturers like HP, Dell, Lenovo, and ASUS sometimes include a Wireless switch in BIOS that can completely disable the Wi-Fi adapter. This is useful for:

Security (e.g., corporate laptops)
Troubleshooting hardware issues
Saving battery in special conditions

If Wi-Fi is disabled here, Windows 11 won’t see the wireless card—no matter how many times you reinstall drivers.

When Should You Enable Wi-Fi in BIOS?

You might need to enable Wi-Fi in BIOS if:

The Wi-Fi option is missing in Windows 11 settings.
The wireless adapter doesn’t appear in Device Manager.
You recently reset BIOS to defaults and lost Wi-Fi access.
You disabled it earlier for troubleshooting/security reasons.
The laptop manufacturer requires BIOS-level toggling of wireless networks.

How to Enable Wi-Fi in BIOS on Windows 11 (Step-by-Step)

Follow these steps carefully:

Step 1: Restart Your Computer

Save any open work.
Click Start → Power → Restart.

Step 2: Enter BIOS/UEFI Setup

As soon as your PC restarts, repeatedly press the BIOS key.
- Common keys:
  - HP – F10 or ESC
  - Dell – F2 or F12

👉 If you’re unsure, check your laptop’s manual or manufacturer’s website.

Step 3: Find the Wireless/Wi-Fi Setting

Inside BIOS, navigate using the arrow keys (or mouse in modern UEFI).

Look under menus like:

Advanced
Integrated Peripherals
Wireless Configuration
Networking

You may find an option such as:

Internal WLAN
Wireless LAN
Wi-Fi Device

Step 4: Enable Wi-Fi

Highlight the Wi-Fi/WLAN option.
Change it from Disabled → Enabled.
Press F10 to save and exit.
Your PC will restart into Windows 11.

Step 5: Check Wi-Fi in Windows 11

Press Win + I to open Settings.
Go to Network & Internet → Wi-Fi.
Toggle Wi-Fi ON.
Connect to your wireless network.

Troubleshooting: Wi-Fi Still Not Working After Enabling in BIOS

Sometimes, even after enabling Wi-Fi in BIOS, it won’t show up in Windows 11. Try these fixes:

1. Check Device Manager

Press Win + X → Device Manager.
Expand Network adapters.
Look for Wireless LAN/Wi-Fi adapter.
If missing, your Wi-Fi card may be faulty or improperly installed.

2. Update or Reinstall Drivers

Go to your manufacturer’s support site.
Download the latest Wi-Fi driver for Windows 11.
Install and restart.

3. Run Windows Network Troubleshooter

Go to Settings → Network & Internet → Advanced Network Settings.
Click Network Troubleshooter.

4. Check Hardware Switch

Some laptops (especially older HP/Lenovo models) have a physical Wi-Fi switch or a function key (Fn + F2/F3) that enables/disables Wi-Fi.

5. Reset Network Settings

Go to Settings → Network & Internet → Advanced Network Settings → Network Reset.
Click Reset Now.
