Enter the password when prompted and click “Join”

This process clears any corrupted network settings specific to your WiFi connection and establishes a fresh configuration, which can resolve persistent Apple computer WiFi not working issues.

Fix #4: Reset PRAM/NVRAM

Parameter RAM (PRAM) and Non-Volatile RAM (NVRAM) store certain settings on your Mac, including some network configurations. Resetting these can help when your Apple computer WiFi not working problem persists after trying the above solutions.

How to reset PRAM/NVRAM:

Shut down your Mac
Press the power button to turn it on
Immediately press and hold Command + Option + P + R
Hold these keys for about 20 seconds
Release the keys when you hear the startup sound a second time (on older Macs) or when the Apple logo appears and disappears for the second time (on newer Macs)

After your Mac finishes starting up, check if your WiFi connection works properly. This reset clears stored network settings that might be causing conflicts with your current connection attempts.

Fix #5: Create a New Network Location

Creating a fresh network location in macOS can resolve issues when your network configuration becomes corrupted but isn’t fixed by the previous methods.

Steps to create a new network location:

Go to System Preferences (or System Settings) > Network
Click on the Location dropdown menu at the top
Select “Edit Locations…”
Click the plus (+) button to add a new location
Name it something like “New Network” or “Fresh Setup”
Click “Done”
Ensure your new location is selected in the dropdown
