Issue: How to Fix “Wi-Fi: No Hardware Installed” Error on MacBook?

My MacBook went to the sleeping mode. Once I brought it back, I was unable to connect to Wi-Fi. I reset the router, but it was not a problem. My phone was connected to the same Wi-FI, and everything was OK. However, I rebooted MacBook, and I was still unable to connect. Besides, I noticed the message saying “Wi-Fi: No Hardware Installed.” What is wrong with my laptop?

Solved Answer

“Wi-Fi: No Hardware Installed” is Mac OS X error that might show when the computer is brought back from sleep. The error occurs when the device cannot connect to Wi-Fi. Nevertheless, restarting computer or laptop often solves connectivity problems; this time it won't help to get rid and fix this error.

Connectivity issues are always annoying. However, this one can be fixed quite easily. Often the source of the error is System Management Controller (SMC). The SMC is responsible for controlling various system settings, such as power management, sleep and awake mode, keyboard backlight, and more.

Thus, when your computer goes to sleep mode, SMC controls what services and devices can be shut down in order to save battery life on MacBook. When you wake up your laptop, you should connect to the Wi-Fi automatically or get a chance to do it manually. However, sometimes the SMC is mistaken and keeps Wi-Fi adapter turned off. Then you receive “Wi-Fi: No Hardware Installed” error.

However, this problem is easy to solve. In order to fix “Wi-Fi: No Hardware Installed” error, you have to reset System Management Controller.

Prevent websites, ISP, and other parties from tracking you

Private Internet Access is a VPN that can prevent your Internet Service Provider, the government, and third-parties from tracking your online and allow you to stay completely anonymous. The software provides dedicated servers for torrenting and streaming, ensuring optimal performance and not slowing you down. You can also bypass geo-restrictions and view such services as Netflix, BBC, Disney+, and other popular streaming services without limitations, regardless of where you are.

A VPN is also crucial when it comes to user privacy. Online trackers such as cookies can not only be used by social media platforms and other websites but also your Internet Service Provider and the government. Even if you apply the most secure settings via your web browser, you can still be tracked via apps that you are connected to the internet. Besides, privacy-focused browsers like Tor is are not an optimal choice due to diminished connection speed.

Therefore, to stay completely anonymous and prevent the ISP and the government from spying on you, you should employ Private Internet Access VPN. It will allow you to connect to the internet while being completely anonymous, prevent trackers, ads, as well as malicious content. Most importantly, you will prevent the illegal surveillance activities that NSA and other governmental institutions are performing behind your back.


Recover your lost files quickly

Unforeseen circumstances can happen at any time while using the computer: it can turn off due to a power cut, a Blue Screen of Death (BSoD) can occur, or random Windows updates can decide to reboot the machine when you went away for a few minutes. As a result, your schoolwork, important documents, and other data might be lost.

Additionally, you might also be attacked by malware that can corrupt your Windows or encrypt files with a robust encryption algorithm, and ask for a ransom in Bitcoin for the decryption tool. Cybercriminals might not deliver what they promised, however, so it is better to attempt alternative file recovery methods that could help you to retrieve at least some portion of the lost data.

Data recovery software is one of the options that could help you recover your files. Once you delete a file, it does not vanish into thin air – it remains on your system as long as no new data is written on top of it. Data Recovery Pro is recovery software that searchers for working copies of deleted files within your hard drive. By using the tool, you can prevent loss of valuable documents, school work, personal pictures, and other crucial files.
