📶 Understanding Mac Wi-Fi
macOS Wi-Fi has multiple layers: hardware radio, driver, and software. Understanding this helps pinpoint problems.
- Wi-Fi radio: The actual wireless chip. If dead, nothing works
- Wi-Fi drivers: Software that controls the hardware
- Network settings: Configuration for connecting to networks
- If Wi-Fi icon is missing, the hardware or driver has failed
- If icon is present but grayed out, the radio is disabled or needs a reset
📡 Fix #1: Enable Wi-Fi
- Click the Wi-Fi icon in the menu bar (top-right)
- If Wi-Fi is OFF, click to turn it ON — the icon should change color to indicate it's active
- Wait 10 seconds for your Mac to scan for networks
- You should now see a list of available networks
- If still no networks appear, proceed to Fix #2
🔄 Fix #2: Forget and Rejoin Network
- Click Wi-Fi icon → Wi-Fi Settings
- Find your network in the list
- Click the information (i) icon next to your network
- Click 'Forget This Network'
- Click Wi-Fi icon again and select your network
- Enter the Wi-Fi password if prompted
- Wait 10-15 seconds to connect
🔧 Fix #3: Restart Wi-Fi Module
- Hold Shift + Option
- Click Wi-Fi icon in menu bar while holding keys
- Look for 'Turn Wi-Fi Off' — click it
- Wait 10 seconds
- Click Wi-Fi icon again and turn Wi-Fi back ON
