How to Fix Laptop WiFi Not Working

WiFi issues are among the most common laptop complaints. Before assuming hardware failure, try these proven software fixes.

Windows WiFi Fixes

1. Check WiFi Toggle: Press Fn + WiFi key (varies by brand). Check Action Center for Airplane mode. 2. Network Reset: Settings → Network → Network Reset. 3. Driver Reinstall: Device Manager → Network Adapters → right-click WiFi card → Uninstall → Restart. Windows will auto-reinstall. 4. DNS Flush: Open CMD as admin, run ipconfig /flushdns then netsh winsock reset.

Mac WiFi Fixes

1. Click WiFi icon → Turn WiFi Off → wait 30 seconds → Turn On. 2. System Settings → Network → WiFi → Advanced → remove saved networks → re-add. 3. Delete WiFi preference files: remove /Library/Preferences/SystemConfiguration/com.apple.airport* then restart.

Hardware WiFi Card Replacement

If all software fixes fail, the internal WiFi card (usually Intel AX200/AX210 or Qualcomm) may need replacement. This is a 30-minute repair at Xigox. WiFi card replacement: ₹999–₹2,499 depending on the card standard (WiFi 5/6/6E).
