When you see the “Wi-Fi: No hardware installed” message, it indicates that the system is not recognizing its built-in Wi-Fi hardware. Sure, the message is annoying, but this is just the tip of the iceberg. 

Suppose your Mac can’t connect to its hardware. In that case, daily activities like browsing the internet or streaming shows are a no-go, and you can forget about joining meetings or collaborating in workspaces. 

Fortunately, the “Wi-Fi: No hardware installed” message is a common problem. So, I created this guide to help you sort out that annoying message once and for all. Let’s start.

What to do when my Mac says no Wi-Fi hardware installed?

At its core, the “Wi-Fi: No hardware installed” problem is a communication breakdown between your Mac’s software and hardware. There are multiple causes and, thus, multiple solutions.

The most common solution? Just restart your Mac. However, if the message is still being displayed after you turn the Mac back on, you’ll need to follow these steps:

Reset your network settings

Corrupted network settings can lead to the “Wi-Fi: No hardware installed” message. Fixing this is easy. Just reset these settings to give your Mac a fresh start and let it find and reconnect to your networks.

Here’s how to reset your network settings: 

1. Go to the Apple Menu in the menu bar > System Settings > Wi-Fi.
2. Click Details > Forget This Network.

Forget your network

You know how sometimes your network settings can go a little haywire? It happens more often than you might think, especially if there have been some changes to the security protocols. If resetting the network settings doesn’t work to get rid of the Wi-Fi: No hardware installed problem, perhaps it’s time to forget the network. Mismatched settings can lead to errors, like the no hardware installed Wi-Fi MacBook problem.

2. Find your Wi-Fi connection and click the circle with the three dots.

Reset SMC

If your Mac still displays “Wi-Fi: No hardware installed,” you may need to reset the SMC or System Management Controller. The SMC manages basic Mac tasks like power and the Wi-Fi model. Sometimes, it just needs to be reset to clear glitches and operate normally again. 

How you reset the SMC depends on the type of Mac you are using. It will vary depending on whether your Mac has an Apple T2 Security Chip or not:

Type of Mac to reset	What to do
Reset SMC in a Mac with a T2 Security Chip	Press and hold the power button > Wait about 10 seconds > Release the button and let the Mac boot.
Reset SMC in a Mac without a T2 Security Chip	Click the Apple menu > Shut Down > Unplug the power > Wait for about 15 seconds > Plug the power back in > Turn on your Mac.
Reset SMC in a MacBook with a non-removable battery	Click the Apple menu > Shut Down > Disconnect the battery > Hold the power button > Wait for about 5 seconds > Connect the battery > Turn on your Mac.
Reset SMC in a MacBook with a removable battery	Plug your MacBook into power > Press and hold Control + Shift + Option + the power button > Wait about 5 seconds > Release the keys and turn on the MacBook.
Reset SMC in an iMac, Mac Pro, or Mac Mini	Click the Apple menu > Shut Down > Disconnect the power cable > Hold the power button > Wait about 5 seconds > Reconnect the power cable > Turn on your Mac.

If you’re using one of Apple’s newer Macs with an M4 chip, you won't have to do any of these steps. The SMC resets automatically whenever you restart the Mac.

Reset NVRAM

Although rare, sometimes the MacBook Wi-Fi has no hardware installed label because of the Mac’s memory. The NVRAM (Non-Volatile Random-Access Memory) in particular. The NVRAM stores things like screen brightness and network configurations. 

How to reset NVRAM for Intel-based Macs: 

1. Turn off the MacBook. 
2. Turn the MacBook back on and immediately press and hold Command + Option + P + R. 
3. Hold the keys down for 20 seconds before releasing them. 

How to reset NVRAM for M series Macs: 

1. Shut down your Mac > Turn it back on.
2. Press and hold the Option + Command + P + R. 
3. You’ll hear the startup chime twice.
4. Release the keys > Let your Mac boot as usual. 

M series Macs automatically examine the NVRAM at system startup and will reset it if necessary. Therefore, you won’t have to hold down any particular keys; just turn off the Mac, wait, and turn it on again. 

Update or reinstall macOS

Still no success? Sometimes, the problem is in the operating system. It’s easy to fix as Apple regularly patches bugs and security holes. All you have to do is check your Mac for software updates. If this is the cause behind the Wi-Fi: No hardware installed issue, then it should be fixed straight after the update is complete.
