Today, we are with you and can not imagine a normal workflow without an internet connection, but the classic wired networks already go down in history. Of course, it is very inconvenient every time to connect a long and not the most inconspicuous wire to a MacBook, especially considering the fact that in recent models they decided to refuse the Ethernet connector. Everything is logical: the speed of modern LTE or Wi-Fi networks is enough to comfortably play even online games or watch a movie in HD directly from the Internet, what about standard web surfing or mail exchange? But to use 3G/LTE with your Mac, you also need an additional device – a modem, but the Wi-Fi module has long been built into the MacBook and iMac of all models.

In this article we will see how to deal with the error associated with the disappearance of the Wi-Fi module from your Mac. Usually this problem is accompanied by the message “Wi-Fi: No Hardware Installed”.

Most often, the MacBook does not see the wifi network for the following reasons:

  • Software issues;
  • Wi-Fi module hardware failure;
  • Damaged or disabled Wi-Fi antennas;
  • Motherboard malfunction.
