In this article, we'll explore different aspects of this issue and provide you with steps to troubleshoot and resolve the problem.
Checking Hardware Connections
The first step in troubleshooting the "WiFi No Hardware Installed" issue on your Mac is to ensure that all the hardware connections are intact. Start by checking the physical connections of your WiFi adapter or card. If you're using a MacBook, ensure that the wireless card is securely connected to the logic board. For iMacs and Mac Pros, ensure that the wireless adapter is properly connected to the PCI slot.
If you've recently installed or upgraded any hardware components on your Mac, such as RAM or a new hard drive, there's a chance that the WiFi card might have been accidentally disconnected. In such cases, open your Mac's casing and carefully reseat the WiFi card in its respective slot. Be cautious when handling internal components and consider seeking professional assistance if you're not familiar with hardware installations.
After checking the physical connections, restart your Mac and see if the "WiFi No Hardware Installed" message persists. If it does, proceed to the next troubleshooting step.
Resetting SMC and PRAM/NVRAM
If the previous step didn't resolve the issue, the next step is to reset the System Management Controller (SMC) and the Parameter RAM (PRAM) or Non-Volatile Random Access Memory (NVRAM) on your Mac.
- To reset the SMC, shut down your Mac and disconnect the power cord. Wait for a few seconds and reconnect the power cord. Press and hold the power button for 10 seconds, then release it and turn on your Mac.
- To reset the PRAM/NVRAM, start by shutting down your Mac. Press the power button and immediately hold down the Command (⌘) + Option + P + R keys. Keep holding the keys until you hear the startup chime for the second time, then release them. Your Mac will restart, and you can let go of the keys.
After resetting the SMC and PRAM/NVRAM, check if the WiFi issue has been resolved. If not, continue to the next troubleshooting step.
Updating macOS and Drivers
An outdated macOS version or incompatible WiFi drivers can sometimes cause the "WiFi No Hardware Installed" issue on your Mac. Therefore, it's important to ensure that you're running the latest macOS version and have updated WiFi drivers.
